15) TNPCB IN ITS AFFIDAVIT BEFORE MADRAS HIGH COURT BLINDLY ACCEPTED NPCIL PLEADINGS:
18.4. It is stated that the Emergency Preparedness Manual has been approved by the AERB and reported in the compliance report dated 7.6.2012 and the NPCIL has also conducted a mock drill to assess the emergency preparedness, but the TNPCB is not a member in the Emergency Preparedness Manual.

(Para-5, 6 & page 17 for ESL data upto16km and upto 30km from reactor, NPCIL)
1.
The importance and essentiality of some of the
17 conditions are explained below.
1)
The 1st recommendation for an alternate
back-up provision is required firstly for charging the water to the secondary
side of the steam generators, secondly to provide for make up of borated water
to the spent fuel pools and thirdly to inject borated water in the reactor
coolant system for strengthening the safety systems. AERB should not down play this crucial
recommendation virtually as a 6th finger. Infact, NPCIL proposed on
27-3-2012 to construct a water storage tank of 8000 cu.m capacity to tackle
this problem and it should have been allowed to complete this work within 6
months i.e. by 27-9-2012 or atleast by now it should have been completed. But several committees were appointed to take
a final decision that resulted an undue delay and naturally the AERB must also
make a corresponding delay in permitting the initial fuel loading which should
not be allowed without the implementation of the full scale safety
provisions.
2)
The 2nd recommendation pertains to
increasing the emergency water storage facility for the purpose of core decay
heat removal during a period of at least one week. This is also very crucial safety measure as a
second line of defense. It is surprising
that AERB justifies the existing water storage both for reactor cooling and
also spent fuel and such storage is available only for a limited duration and
AERB further certifies that the existing water availability for the limited
duration is sufficient enough to make alternate arrangement to bring another
source of water from outside the nuclear plant site. They have never specified the exact number of
days that constitute the limited period.
Further they are not sure of the
exact external sources that are available for bringing the required water for
the emergency purpose of cooling the reactor and also the spent fuel
pools. The experience at Fukushima
reactor proved that the inadequacy of cooling water had caused the havoc. Hence additional water storage amounting to
one week’s requirement is a must to augment safety measures.
3)
The 3rd recommendation deals
with mobile self powered pumping equipment for emergency use. AERB should not underplay the urgent need to
provide this mobile pumping equipment for emergency use by stating that the
fire tenders presently available can be used for the purpose and that this
equipment will be made available as a long term measure. Inspite of the fact a nuclear plant at Japan
recently faced an accident due to break down of sources of external electrical
supply consequent to the high winds of a cyclone have damaged the power supply
systems. Hence this additional measure
must be immediately installed before grant of license for the plant.
4)
Regarding the 4th recommendation
pertaining to the facilities for
monitoring safety parameters using portable power packs, AERB should
have permitted NPCIL to complete this work by October, 2012 and it should not
be classified as a long term measure.
Regarding
the finalization of emergency operating procedures for conditions arising beyond the design basis accidents AERB should
not have merely stated that KKNPP is provided with beyond design based
accidents management and that emergency operating procedures have been
prepared and finalized. AERB further
states that these procedures are for handling situations within the plant
and are not related to any off-site
emergency for which separately approved
emergency plans are already in place. It
must be remembered that the Fukushima
accident has shown to the world that they failed in finalization of
emergency operating procedures for
beyond design based accident conditions because
they initially fixed a distance
of only 20km. for the emergency planning
zone for evacuating the victims and it was subsequently increased to 30km. and
later on upto 40km for sheltering the victims of the nuclear accident. Hence this recommendation made by the Task
Force committee should not be misinterpreted to downgrade nuclear safety and
thereby compromise with public safety .
a)
The view of AERB that the approved off-site
emergency plans already in place will provide public safety is completely wrong
because AERB provided for an emergency planning zone extending upto 16km from
the reactor location while the standards prescribed by IAEA specified the EPZ
upto 50 to 100km and the NDMA of India insists that nuclear plants in India
shall adopt these international standards to ensure safety.
b)
Hence
AERB and NPCIL should not play with the lives of the people by promoting
Nuclear plants which not only slowly ruin public health, fisheries wealth,
agriculture and the national economy.
Infact Japan is planning to pay compensation amounting to about Rs.4
lakh crores to the victims Fukushima Nuclear Plant disaster for the
present. If Kudankulam nuclear reactor
is subjected to a similar accident due to external threats like terrorist,
bombing of the reactor by aeroplanes as was done by the terrorists on 9/11
September, 2001 indestroying a very huge structure like the world Trade Center
in New York the destruction of nuclear reactors at Kudankulam is equally, if
not more, likely. Even the cyclones can
disrupt the power systems with the result that the recent hurricane that hit
New Jersey during November, 2012 has resulted in closing of several nuclear
plants in USA.
c)
Since the
present cost of KKNPP is only Rs.14,000crores and its damaging cost due to an
accident will be about Rs.4 lakh crores.
It will be much cheaper and safer to abandon this KKNPP or otherwise
convert the reactors to produce electricity by using alternate fuels like oil,
coal and natural gas which are readily available in India and particularly since
lignite is available in Tamil Nadu
5)
With regard to 5th recommendation
it deals with finalisation of Emergency Operating Procedures (EOP) for beyond
design basis accidents. NPCIL replied
that EOP for some post irradiation examinations (PIE) have been made and the
remaining are in progress as a short term measure. This is not correct. Emergency preparedness plans under fifth
level of nuclear safety under the defense indepth philosophy essentially
requires the nuclear accident classification under the 7 grades of nuclear
accidents and incidents and the relevant source factors are accidental radioactive
emissions from the chimney stack of the reactors must be used to predict ground
level concentrations for taking up evacuations of people likely to be
victimized and also other people who have to be sheltered and more distant
people who must be administered potassium iodine tablets to protect their
health. This emergency drills which have
to be conducted once before starting
production of electricity must be done before sanctioning clearance for the
commencement of operations.
6)
The 6th recommendation pertaining to assessment of the
primary containment for ultimate load bearing capacity must be confirmed because
the task force committee consisting of several nuclear safety experts made this
strong recommendation only after realizing that there is an existing deficiency
in the matter.
7)
The 7th recommendation that the
doors and barrels of airlocks have to be qualified for proof test pressure
cannot be considered to have been completed by the NPCIL by merely stating that
the qualification of barrel and other door of tapped anchor location has been
carried out by merely the design analysis
and hence meets the requirement. The
suggestion made by the task force is very important and hence must be carried
out immediately before sanctioning license for operation of the nuclear
reactors.
8) The 8th recommendation for ensuring
that the highly active water used for cooling the core catcher vessel under
beyond the design basis accident shall be contained inside the primary containment
cannot be brushed aside by the NPCIL and the AERB by providing a casual
statement that the required analysis is being carried out on a long-term
basis. It virtually means that the AERB
and the NPCIL are indirectly promoting conditions for easy triggering of accidents.
9) With regard to the 9th
recommendation that demands reconfirmation of design adequacy of hydrogen
management system the NPCIL without applying its mind for implementing
suggested action it is simply stating that the conditions complied with by
mentioning that the design adequacy of
hydrogen management system has been reviewed and all the aspects are addressed.
10) With regard to the 10th
recommendation on the Environmental qualification of core catcher temperature
monitoring system the NPCIL is stating that this requirement has been complied
with as the instrumentation for the core catcher monitoring has been qualified
without giving the details of how the system will work efficiently to promote
environmental safety even during severe accidental conditions.
11)
The 11th recommendation
pertaining to adequacy of design provision for remote water addition to the
core catcher the NPCIL replies that this recommendation is complied with by
stating water addition provision through hook up point already exists and that
it is adequate. This attitude of the
NPCIL that the actions already taken by them for remote water addition to the
core catcher is sufficient must be
considered in the light of the fact that
the task force committee experts have examined the issue in depth and found inadequacy
conditions that interfere with absolute safety of the nuclear plant and hence
they must take positive action.
12) with regard to the 12th
recommendation that calls for adequacy of instrumentation for monitoring plant
status during a beyond the design basis
accident the NPCIL casually states that
all important parameters of the plant during the major accident will be monitored and that
provisions to extend power supply to these instruments will be implemented in
stages a long term measure. This delayed
action fails to provide immediate measures needed to monitor the fluctuations
in performance of various instruments and equipment that need to be controlled in time by
integrating the crucial feedback from various components of the instruments and
parts of the equipment that are used for preventing, controlling and management
of failures that trigger nuclear accidents.
Hence immediate action must be
taken to review the adequacy of instruments for monitoring the plant status
during the design basis accident.
13) With regard to 13th
recommendation demanding that the details of margin available on the location
of various safety related structures,
systems and components like the various kinds of back -up power generators
above design basis flood level should be reviewed again, the NPCIL has blindly
replied that this requirement is complied with because the margins have been
reviewed and found adequate by different set of experts who are not at all
superior to the experts of the task force and another set of experts who
reviewed the report and thereby made NPCIL filed an affidavit before the court
promising that all the 17 recommendations will be fully implemented by
October-November, 2012.
14) With regard to the 14th
recommendation emphasizing the need for design provision that has been deleted
must be reexamined the NPCIL without any
serious application of mind blindly affirmed that this provision is complied
with just because the existing design and procedures of the nuclear plant avoid
the containment over-pressurisation by having long-term decay heat removal system
without knowing that this system will fail for one reason or the other due to a
beyond design basis accident. Hence the
containment venting provision that has been removed must be reinstalled after thorough reexamination.
15) With regard to the 15th
recommendation that the back-up sources for water injunction to steam
generators secondary side should be seismically qualified the NPCIL submitted
that a seismically qualified water storage tank of 8000cu.m capacity will cater to this requirement as a
short-term measure but this measure could have been implemented within 6 months
and before October-November, 2012 and also before grant of clearance by AERB
for operation of the reactors.
16) With regard to the 16th
recommendation demands that the provisions for addition of water to core
catcher required a detailed study for ensuring that there is no possibility of any stream
explosion. But the NPCIL reports
compliance with this demand on the plea
that the existing design and procedures
of nuclear plant prevent possibility of steam explosion. But this unscientific reply cannot be
accepted to ensure nuclear safety and public safety and it should be studied indepth and remedial action must be taken
before grant of clearance for operation of the reactors.
17) With regard to the 17th
recommendation demands that provision of additional back-up power supply
sources for performing essential safety functions l9ke air cooled diesel
generators located at a high elevation should be considered. But this crucial recommendation is not
seriously taken by the NPCIL for ensuring safety of the nuclear plant and the public by
stating casually that the provision of a mobile diesel generator will be made
for performing essential functions as a long-term measure. This recommendation is based upon the serial serial
failure of several diesel generators except the one air cooled reactor
over a small mould located at an
elevation near Fukushima 6th reactor at Fukushima which provided the
back up system that proved successful even during the period of the Fukushima
disaster. Hence AERB and NPCIL shall not
take these recommendations of the expert committee casually but should get them
implemented fully before granting permission for starting the operations at the
nuclear reactors of Kudankulam.
The
affidavit filed by AERB that it satisfied itself that the said recommendations
will be duly complied with cannot taken for a granted to ensure safety because
the promise made cannot be true unless
it is fulfilled by taking the practical step of implementing measures
immediately before the reactors are permitted to become operational. That the
AERB as satisfied itself that NPCIL has taken all the necessary steps to comply
with all the said recommendations made by the Task Force and the high level
committee cannot be valid unless all the recommendations implemented in
toto as accepted by the NPCIL for
executing the practical implementation of those measures before
October-November, 2012. Otherwise the
promise becomes a pie in the sky as a catastrophic accident can occur within a
short-time and the obstacles placed in the path of implementing the
recommendations becomes major cause of a nuclear catastrophy like the one at
Fukushima.
14) PERMISSIONS
GIVEN TO KUDANKULAM NUCLEAR PLANT ARE BASED ON WRONG INFORMATION
(From Madras High Court Judgement on Kudankulam):
108. By taking note of the overall situation explained in detail, we
are of the view that the KKNPP in respect of Units 1 and 2 do not suffer from
any infirmities either for want of any clearance from any of the authorities,
including the MoEF, AERB, TNPCB, and the Department of Atomic Energy, and there
is absolutely no impediment for the NPCIL to proceed with the project
15) TNPCB IN ITS AFFIDAVIT BEFORE MADRAS HIGH COURT BLINDLY ACCEPTED NPCIL PLEADINGS:
18.4. It is stated that the Emergency Preparedness Manual has been approved by the AERB and reported in the compliance report dated 7.6.2012 and the NPCIL has also conducted a mock drill to assess the emergency preparedness, but the TNPCB is not a member in the Emergency Preparedness Manual.
16) AFFIDAVIT FILED BY DISTRICT COLLECTOR STATES THAT STATE GOVERNMENT
DECIDED ON THE PLANT:
19.1. In the counter affidavit filed by
the District Collector, Tirunelveli, it is stated that action has to be taken against the protestors sensitively,
since they are using children, ladies and common public as a shield. It is stated that the Tamil Nadu State
Cabinet on 19.3.2012 has decided to take immediate action on commissioning of
KKNPP and has requested all people to cooperate with the decision of the
Government.
17) ADVOCATE
FOR PETITIONER OBJECTED TO CLEARING THE REACTORS WITHOUT ESTABLISHING
FEASIBILITY OF EVACUATION UPTO 16KM FROM THE PLANT IN CASE OF AN ACCIDENT:
20.12.
While it is the admitted case of the respondents that the recommendations of
the AERB High Level Committee for review of safety of Indian power plants in
the light of the Fukushima accident is being carried out by the NPCIL in a time
bound manner, it is his submission that
till such compliance is made, actual fuel loading of KKNPP cannot be done and
that also requires a fresh environmental clearance.
21.7.
With regard to the stand of the TNPCB that two volumes of on-site and off-site
preparedness plans are shown during inspection approved by AERB and that the mock drill has been conducted to
assess the emergency preparedness, it is the contention of the learned Senior
Counsel that mock drill was done in a small hamlet called Nakkaneri, while the
Comprehensive Environment Impact Assessment of KKNPP specifically states that
the emergency preparedness operations have to be done in the monitoring zone,
which is within 30 Kms. radius from the Power Plant.
It is stated that the very condition is to
create awareness among the people and, therefore, the conducting of a mock
drill only in Nakkaneri is not inaccordance with the requirements. Insofar as it relates to the off-site
emergency preparedness, the District Collector must do the act as a continuing
process. He would also refer to
another special condition which contemplates the regular training drills for
personnel, and would submit that the TNPCB has merely chosen to state that the
unit has training programmes and no records have been produced to show that
actually they conducted the training
18) NPCIL COUNSEL MISINFORMS HIGH COURT THAT
PERMITS WERE GIVEN AS PER LAW:
25.1.
Mr.Krishna Srinivasan, learned counsel
appearing for the NPCIL would submit that the plant has got approval
from all regulatory bodies up to the present stage in which fuel loading has
been started and other requirements have been scrupulously complied with. It is his submission that the Four Expert Committees
have considered the Post Fukushima accident and found that there is no
possibility for any nuclear risk either in Kalpakkam or in Kudankulam and
moreover, even in the year 2004 when tsunami occurred, the Kalpakkam project
has not been affected. He further submitted that the experts from
AERB, Committees appointed by the Central Government and the Committees
appointed by the State Government, who are all eminent persons in the field of
science and technology after visiting
the plant and meeting the people have given reports to the effect the KKNPP is
a safe project. He would submit that
experts views have been obtained on many occasions and emergency preparedness
and mock drill has been done in accordance with law.
19) TAMIL NADU ADVOCATE MISLEADS COURT THAT MOCK
DRILL WAS DONE AS PER LAW:
27.1. Mr.Inbadurai, learned Special Government
Pleader appearing for the State Government while producing the sealed cover
report of the Expert Committee appointed
by the Government of Tamil Nadu has forwarded the report dated 27.2.2012. He would submit that in fact as per the AERB
Guidelines, mock drill was conducted and emergency preparedness plan was made
in Nakkaneri Village, which is near the project itself. According to him, off-site emergency drill
has been done in the manner known to law and the authorities have been educated
properly so that in the event of any eventuality they will guide the people in
a proper manner.
20) The environmental clearance for the
Kudankulam reactors obtained from the Union Ministry of Environment and forests
is based on insufficient technical data and false information.
a) for instance the National Environmental Engineering
Research Institute (NEERI) prepared an Environmental Impact Assessment report
for Kudankulam Nuclear reactors 1 &2 submitted to the NPCIL in January,
2003. This report is entitled as a
comprehensive EIA report of Nuclear Power Plant (Units 1&2)
Kudnakulam. Since the report was
prepared in January 2003 it must have to taken into consideration the
environmental regulations to be followed for the EIA report based on the rules
of the environmental protection Act, 1986.
This report has not taken into consideration the scientific data to be
provided under the items 11, 12 and 13 of the questionnaire under schedule-II
of the application to be sent to the Union Ministry of Environment for
obtaining the environmental clearance for the project. These items pertain to preparation of the
risk analysis report, disaster management report, environmental impact
assessment report and the environmental management reports. For the Environmental Impact Assessment
report NEERI has furnished under Chapter-III – Prediction of Impacts the
procedures followed for air pollution models used to predict ground level concentrations
of radioactive pollutants discharge from the chimney stacks of the reactors for
the summer, winter and post monsoon seasons and
the figures 3.1.1 upto 3.1.9 present the graphics of the isodoses of radioactivity due to the nuclear
plant for about 20 km from the plant and table 3.1.1 presents the radioactive
pollutants released from the stacks of the reactors into the environment. Although NEERI has the necessary software and
also the experts to prepare similar ground level concentrations of radioactive
pollutants due to radioactive releases from the chimney stacks during a major
credible nuclear accident and thus NEERI could have predicted the radioactivity
deposits for 30km from the nuclear plant to identify the levels of
radioactivity that will slowly poison public health, soils, agriculture fields
and the human and animal populations.
Such predictions could have been used to identify the areas to be
provided with safety measures for evacuation of the victims of radioactive
pollution and also to shelter lakhs of people exposed to high radioactivity and
many others whose health could be protected by distributing potassium iodine
tablets even beyond the distance of 30km if the exposure dose of radioactivity
is going to be in excess of the stipulated standards as per ICRP and AERB
guidelines.
b) unfortunately the Union Ministry of Environment and
Forests did not take into consideration these crucial factors in granting
Environmental clearance for the nuclear plants at Kudankulam. If Environemtnal clearance is given by the
Union Ministry on the basis of inadequacy of data and false data the
environmental clearances so far given can be cancelled.
c) As already pointed out the Environmental clearance
revalidated in September,2001 is based on
false information and hence that clearance for nuclear reactors 1 and 2
at Kudankulam must be treated as illegal and hence invalid. Hence fresh
environmental clearance must be given for the project.

CONTRADICTIONS
ON DISASTER MANAGEMENT FOR KKNPP
1) For the purpose of
planning for serious accidents, if any, an area of 16 km around the plant is
considered as the Emergency Planning Zone. The AERB Code of Practice on Safety
in Nuclear Power Plant Siting states: During emergency, availability of
transportation network means of communication, etc. which are of significance
during emergency condition shall be checked. A radial distance of 16 km from
the plant may be considered for this purpose.
2) Radiation in the Surrounding Area
Utmost attention
is given to safety of the environment and the public in all aspects of nuclear
power from siting, design, construction, commissioning, and operation and up to
decommissioning. The entire effort is to ensure that release of any radioactivity
or radiation in the public domain affecting the public and the environment is
minimized to be well within the prescribed regulatory limits. A principle of
“As Low As Reasonably Achievable (ALARA)” is adopted in this regard. The
radiation dose from nuclear power plants in operation in India has been found
to be a negligible fraction of the naturally existing background radiation. The
details are:
An
Environmental Survey Laboratory (ESL) is set up at the site before the start of
operation of the reactors, which collects data of several environmental
matrices like air, water, soil, vegetation, crops, fish, meat, etc. It
establishes a baseline. Subsequent to start of operation of the station, the
ESL monitors the environmental matrices even beyond emergency planning zone of
16 km (usually up to 30 km of the site) for radioactivity (elements like
Iodine-131/133 Strontium-90 etc) and radiation levels. The experience over the
last 40 years has been that at such distances no significant increase in
radiation levels above the baseline data is found at Indian nuclear power plant
sites.
3)
AERB ADOPTS STANDARDS AND GUIDELINES FOR NPP FOLLOWED BY IAEA
Detailed technical safety requirement developed by AERB including those for siting and design
of NPPs are published in the safety
Codes and Guides, which are available
n AERB website (www.aerb.gov.in). These requirements are in line with safety standards of International Atomic Energy Agency (IAEA) and other international guidelines.
4)
AERB FORMED HIGH LEVEL COMMITTEE
TO REVIEW SAFETY OF NPP WITH RESTRICTED TERMS
Annexure2 MEASURES TAKEN POST FUKUSHIMA NUCLEAR
ACCIDENT IN JAPAN
Post
the Fukushima Nuclear Accident in Japan,
AERB has taken several proactive
measures, which are as follows:
•
A High Level Committee under the
Chairmanship of Shri S. K. Sharma,
Former Chairman, AERB and consisting
of experts from Central Water and Power
Research Station, Indian
Institute of Tropical Meteorology &IIT (Madras) apart
from BARC, NPCIL & AERB was constituted to review safety of Indian NPPs in the
light of the lessons from Fukushima. The Committee shall assess the
– The capability of Indian Nuclear
Power Plants to withstand earthquakes
and other external events such as tsunamis, cyclones, floods, etc.
– Adequacy of provisions available
to ensure safety in case of such events,
both within and beyond design basis.
The Committee has started functioning and has formed several working groups.
•
An inhouse Monitoring Cell has been constituted
to continuously follow the events at
Fukushima and to keep a close vigil
on the radiation/contamination
levels in Japan and India.
•
Daily updates on AERB website

•
AERB has also informed to the Food
Safety and Standards Authority of
India (FSSAI) that currently there are
three laboratories in India which have been
identified for testing of food items
for contamination. AERB representative
attended the Meeting organized by FSSAI for taking a decision related to import
of Food items from Japan
•
With respect to screening of passengers coming from Japan, AERB has informed
National Disaster Management Authority (NDMA) that at present there is no such
requirement.
•
Statements and responses by Chairman, Vice
Chairman and Secretary, AERB to
the
queries from Journalists, Electronic Media,

safety of Indian Nuclear Power Plants as well as effect of Japan incident on India.
5)
AERB HAS EQUAL OR SUPERIOR
STANDARDS FOR EMISSIONS THAN PRESCRIBED BY IAEA
(From Madras High Court Judgement
on Kudankulam):
(ix) AERB has prescribed limits for discharges and ensures that the
radiation releases are well within the prescribed limits. The limits prescribed
are based on international recommendations, and in all cases are either equal
to or more stringent than these.
6)
PERMISSIONS GIVEN TO KUDANKULAM
NUCLEAR PLANT ARE BASED ON WRONG INFORMATION
(From Madras High Court Judgement on Kudankulam):
108. By taking note of the overall situation explained in detail, we
are of the view that the KKNPP in respect of Units 1 and 2 do not suffer from
any infirmities either for want of any clearance from any of the authorities,
including the MoEF, AERB, TNPCB, and the Department of Atomic Energy, and there
is absolutely no impediment for the NPCIL to proceed with the project
7)
MADRAS HIGH COURT WAS INFORMED
THAT AERB DIRECTIONS WERE FOLLOWED:
17.9.2.
While reiterating that the plant is most advanced one called Generation III
Plus Plant, the various advanced features of the plant, as stated by the Union
of India and AERB, have been emphasized.
It is also stated that even in case of severe accident, there is no need
for evacuation of persons or public who may be living beyond the plant
boundary, but still as a next level of defense, an emergency evacuation plan
exists for evacuating the public, which is planned as per the requirement of
the AERB, and as per the direction of AERB, effective mock drills at regular
frequency are being arranged.
17.11. In respect of the next issue of Emergency
Preparedness Plan (EPP) and lack of resources to implement it, it is stated
that the AERB can always direct and instruct the KKNPP Unit to fulfill the
requirement of emergency preparedness plan, in which event the unit is legally
bound to fulfill the said requirements.
17.14.
In effect, the counter affidavit of the NPCIL would reiterate that all safety
measures have been taken and there is absolutely no reason to apprehend any
fear about the safety or otherwise.
8) TNPCB IN ITS AFFIDAVIT BEFORE MADRAS HIGH COURT BLINDLY ACCEPTED
NPCIL REMARKS:
18.3. It is stated that once again the officials of the TNPCB have inspected the KKNPP on 12.6.2012 and it was observed that the unit has furnished the compliance of the conditions appended to the consent for establishment and it was verified that the NPCIL has complied with all requirements, as stipulated in the general and special conditions and, therefore, it is stated that the allegation made by the petitioner that some of the conditions imposed by the TNPCB have not been complied with, is incorrect. It is added that the information stated to have been obtained by the petitioner under the Right to Information Act is outdated and NPCIL has updated the latest compliance vide their letter dated 7.6.2012, which indicates that all the conditions have been complied with.

18.4.
It is stated that the Emergency Preparedness Manual has been approved by the
AERB and reported in the compliance report dated 7.6.2012 and the NPCIL has
also conducted a mock drill to assess the emergency preparedness, but the TNPCB
is not a member in the Emergency Preparedness Manual.
18.7.
Insofar as it relates to the retaining of temperature of cooling water at the
point of confluence in the sea as not exceeding 7oC as prescribed by the MoEF,
it is stated that the TNPCB will take a decision at the time of issuing the
consent to operate
9)
AFFIDAVIT FILED BY DISTRICT
COLLECTOR STATES THAT STATE GOVERNMENT DECIDED ON THE PLANT:
19.1. In the counter affidavit filed by
the District Collector, Tirunelveli, it is stated that action has to be taken against the protestors sensitively,
since they are using children, ladies and common public as a shield. It is stated that the Tamil Nadu State
Cabinet on 19.3.2012 has decided to take immediate action on commissioning of
KKNPP and has requested all people to cooperate with the decision of the
Government. However, the People's
Movement against Nuclear Energy (PMANE) continued their unpermitted fast
against the Government's decision at Idinthakarai seashore. It is stated that road blockades were done by
the protestors opposing the KKNPP and buses were stopped and ultimately on
19.3.201, normalcy has been restored to some extent.
19.4.
It is stated that on 9.6.2012, the Shift Charge Engineer declared a plant
emergency and subsequently, the Site Director reached the plant, declared start
of site emergency exercise; alert messages were sent to all the relevant
officials, including the NPCIL, DAE, AERB, District Collector and the Line
Department officials; and based on inputs from Environmental Survey Lab Team,
the District Collector declared an Off-Site Emergencyand exercise of counter
measures were carried out in three stages, as prescribed in the Emergency Plan.
It is stated that Nakkanery Village, which is situated at a distance of about 7
Kms. From KKNPP, was selected as locally affected area for the purpose of the
said exercise and the exercise was observed by the representatives from AERB,
NPCIL Head Quarters and other officials of the NPCIL. It is also stated that all villages within
16 Kms. radius will be covered under
this exercise as one village in every two years.
10) ADVOCATE FOR PETITIONER OBJECTED TO CLEARING
THE REACTORS WITHOUT ESTABLISHING FEASIBILITY OF EVACUATION UPTO 16KM FROM THE
PLANT IN CASE OF AN ACCIDENT:
20.12.
While it is the admitted case of the respondents that the recommendations of
the AERB High Level Committee for review of safety of Indian power plants in
the light of the Fukushima accident is being carried out by the NPCIL in a time
bound manner, it is his submission that
till such compliance is made, actual fuel loading of KKNPP cannot be done and
that also requires a fresh environmental clearance.
21.7.
With regard to the stand of the TNPCB that two volumes of on-site and off-site
preparedness plans are shown during inspection approved by AERB and that the mock drill has been conducted to
assess the emergency preparedness, it is the contention of the learned Senior
Counsel that mock drill was done in a small hamlet called Nakkaneri, while the
Comprehensive Environment Impact Assessment of KKNPP specifically states that
the emergency preparedness operations have to be done in the monitoring zone, which
is within 30 Kms. radius from the Power Plant.
It is stated that the very condition is to
create awareness among the people and, therefore, the conducting of a mock
drill only in Nakkaneri is not inaccordance with the requirements. Insofar as it relates to the off-site
emergency preparedness, the District Collector must do the act as a continuing
process. He would also refer to
another special condition which contemplates the regular training drills for
personnel, and would submit that the TNPCB has merely chosen to state that the
unit has training programmes and no records have been produced to show that
actually they conducted the training
11)
NPCIL COUNSEL MISINFORMS HIGH COURT THAT PERMITS WERE GIVEN AS PER LAW:
25.1.
Mr.Krishna Srinivasan, learned counsel
appearing for the NPCIL would submit that the plant has got approval
from all regulatory bodies up to the present stage in which fuel loading has
been started and other requirements have been scrupulously complied with. It is his submission that the Four Expert
Committees have considered the Post Fukushima accident and found that there is
no possibility for any nuclear risk either in Kalpakkam or in Kudankulam and
moreover, even in the year 2004 when tsunami occurred, the Kalpakkam project has
not been affected. He further
submitted that the experts from AERB, Committees appointed by the Central
Government and the Committees appointed by the State Government, who are all
eminent persons in the field of science and technology after visiting the plant and meeting the
people have given reports to the effect the KKNPP is a safe project. He would submit that experts views have been
obtained on many occasions and emergency preparedness and mock drill has been
done in accordance with law.
12) AERB ADVOCATE
SURESH STATES THAT PERMISSION WILL BE GIVEN TO REACTORS ONLY AFTER FULFILLING
IMPLEMENTATION OF ADDITIONAL SAFETY FEATURES AS SUGGESTED BY EXPERT COMMITTEES:
26.2. He would rely upon the various
reports of the Experts Committee of AERB and state that before initial fuel loading is done, the
compliance of all the requirements under Annexure VIII will be ensured by the
AERB and it is only after its satisfaction any direction will be given and now
it is brought to the notice of this Court after having been satisfied, the AERB
has given its report giving clearance
13)
TAMIL NADU ADVOCATE MISLEADS COURT THAT MOCK DRILL WAS DONE AS PER LAW:
27.1. Mr.Inbadurai, learned Special Government
Pleader appearing for the State Government while producing the sealed cover
report of the Expert Committee appointed
by the Government of Tamil Nadu has forwarded the report dated 27.2.2012. He would submit that in fact as per the AERB Guidelines,
mock drill was conducted and emergency preparedness plan was made in Nakkaneri
Village, which is near the project itself.
According to him, off-site emergency drill has been done in the manner
known to law and the authorities have been educated properly so that in the
event of any eventuality they will guide the people in a proper manner.
14)
ADDITIONAL SOLICITOR GENERAL
ADMITS ASPECTS OTHER THAN DISASTER MANAGEMENT:
29.5.
It is also submitted that the project was evaluated by the Site Selection
Committee of the Government as per the norms laid down by the AERB Code of
Practice on Safety in Nuclear Power Plant Siting, which includes the assessment
of seismicity, location of faults, geology, foundation conditions, meteorology,
potential of flooding, proximity to airports, military installations,
facilities storing explosive and toxic substances, etc. and the site was also evaluated by the SSC
and approved after due process on 10.11.1989.
15) SITE EVALUATION COMMITTEE FOR KUDANKULAM
ACCEPTED THAT THE SITE IS SUITABLE FROM MAJORITY OF THE CONDITIONS SUITABLE FOR
LOCATING THE NUCLEAR PLANT:
44.
In respect of the designs, the Committee has recommended as follows:
"3.2.
Aspects related to design
1)Radiological
impact should be assessed with proper source terms and relevant dispersion
characteristics of the site. Does limits
prescribed should be met at a distance of 1.6 km in the event of greater
exclusion radius adopted by NPC.
2)Stack
height to be checked by Health Physics Division, BARC considering topography
and dispersion characteristics.
3)Model
studies should be taken up for intake and outfall structure for thermal
pollution and recirculation.
4)Studies
on Biofouling and Jelly-fish etc. that may affect the water supply should be
taken up.
5)Studies
on accretion/erosion rate around the plant site should be carried out. If
required, proper protection should be provided.
6)Design
should be engineered to meet site related design basis events.
7)Atleast
two evacuation routes from plant site during an emergency should be
provided"
45.
Ultimately, the Committee has given its opinion that the Kudankulam site meets
the major criteria for siting 2 x 1000 MWe VVER units and also recommended that
the observations made and the recommendations made are to be implemented at
appropriate stages.
16) TAMILNADU POLLUTION CONTROL BOARD
BLINDLY ACCEPTED EMERGENCY PREPAREDNESS PLAN
A) CONDITION: On site and
off site disaster management plant (DMP) should be prepared as per the
guidelines stipulated by AERB and approved by the National Emergency Response
(NERC) of Department of Atomic Energy, Government of India
B) ANSWER BY TNPCB: Two volumes of onsite and offsite preparedness plan
was shown during inspection approved by AERB
The
unit shall have regular training drills for all personnel to be involved in
handling, storing and processing by updating training manual from time to time
so as to control actual spills of hazardous
materials if any in the quickest possible time.
The unit has training programmes. Hence complied.
17) MADRAS HIGH COURT DIRECTS NPCIL TO
CONDUCT MOCK DRILLS FOR 40 MORE VILLAGES WITHIN 30KM DISTANCE FROM NUCLEAR
PLANT BY INVOLVING THE LOCAL PEOPLE: Even though it is stated that the said exercise was
done in only one village, namely Nakkaneri village, which is stated to be
nearer to the KKNPP, as we are informed that nearly 30 to 40 villages are
within 30 Kms radius of KKNPP, such event must take place in all villages and
more importantly, apart from the officials, as stated above, the people in the
area must be made to participate and an awareness programme must be made to
infuse confidence in the minds of the local people that the project is for the
benefit of the country and there is no need to alarm.
1.
NPCIL presented the Environmental Impact
Assessment (EIA) report of NEERI on Environmental Impact Assessment
(2003). This report is incomplete
because it has not incorporated the risk analysis and disaster management report for a design
basis accident and for beyond the design
basis accident at Kudankulam Nuclear plant. This requirement of risk analysis
and disaster management plan comes under schedule-II of the application for
Environmental clearance for nuclear plant.
Hence EIA report of NEERI cannot be treated as a comprehensive report as
it failed to provide the full details as required under EIA notification
dt.27-1-1994 under the Environmental Protection Act, 1986.
2) Impact area for Emergency Preparedness plan
in case of a nuclear reactor accident was kept at 16km distance from the reactor
by AERB and NPCIL while the EIA report
of 2003 by NEERI prepared at the request of NPCIL has prepared the impact zone for 30km radius from the
reactor. Normally this impact area used
for emergency planning zone (EPZ) for nuclear reactor accidents should be based
on actual calculations for dispersal of radioactive emissions from the reactor
core under different failure conditions and meteorological parameters for
fixing the distance of planning zone
based on radiation exposure of the public for 1.0 mSv/year. Such evacuation distances in practice
extended upto 50km in the case of Fukushima accident on the basis of radiation
exposure of 20mSv/year but Japan has officially extended this Emergency
Planning Zone from 20 to 30km during the accident and declared the extra
distance as voluntary evacuation zone.
3) In the wake of the Fukushima accident
American Environmental organizations revised their emergency preparedness
planning zones from 80km from nuclear plants to more than double the existing
standard of 80km based on topographical and meteorological factors. Even in the case of Three Mile Island
accident the people in the surrounding areas were evacuated upto a distance of
20 miles or 32 km from the nuclear plant.
The Indian Point nuclear plant authorities presented full details on the
radiation doses and their spread over large areas downwind from the reactor and
also compared the disaster scenario with the particulars obtained from the
Fukushima accident scenario.
4) But
the Kudankulam nuclear plant authorities including the NPCIL have transfered the
entire responsibility of preparing the emergency preparedness for a nuclear
accident at Kudankulam lies over the shoulders of the local Tirnelveli District
Collector and Tamil Nadu state Government who will be assisted by the NPCIL,
DAE and other central organizations.
Thus it is the District Collector, Tirnelveili, the Tamil nadu Pollution
Control Board and the Tamilnadu state Government who will be ultimately held responsible for any major failures in the preparation and implementation
of the Emergency Preparedness plans due to nuclear accidents. Unfortunately Tamil Nadu state Government and
its district administrative organizations are not at all qualified even to
understand the damaging impacts of the postulated nuclear accidents and
prepared to meet the emergencies by taking remedial actions and hence they
cannot be expected to undertake this gigantic task and hence lakhs of local
people in southern Tamilnadu districts are bound to suffer from serious public
health hazards and face several risks likely to be created by the inevitable
failure of the Kudankulam reactors for several reasons including external
threats like satellite hits and bombing the enemy countries.
5)
The Nuclear Power Corporation, the Atomic Energy Regulatory Board and the
Kudankulam Nuclear Plant authorities are misleading the public, the central and
state Government on the safety aspects
of the nuclear reactors even by violating the International safety
standards for nuclear plants by refusing to implement the measures dealing with
preparation emergency preparedness plans for design basis accidents under 4th
level of safety under the defense in depth philosophy pertaining to nuclear
safety and also the disaster management stipulated under 5th level
of safety under design in depth philosophy of nuclear safety. Moreover the madras High Court in its judgement
directed the nuclear plant authorities to implement emergency evacuation
measures by making mock drill exercises in more than 30 to 40 villages within
30km radius from Kudankulam and that to the exercises must be done by involving
the local people who will be properly educated about the implications of the
impacts of the Kudankulam nuclear plant.

Comments

3-5 (Safety)
|
NPCIL has tried to dispose of the
safety concerns by nitpicking on words and ignoring the spirit underlying the
constitution of the expert Committee by ARRB on 19-3-2011. The following
observation of the Committee summed up the rationale of its recommendations
Para 4.1
In spite of all the safety
features provided, the extremely remote
possibility of an accident leading
to partial or total melting of fuel in the
reactor core due to unforeseen
reasons should still be deterministically
taken into consideration.
Provisions for management of such an
accident, termed as severe
accident, need to be made such that the
operators are able to control its
progression and mitigate its
consequences in terms of
preventing, or at least minimizing, any
significant adverse impact in the
public domain.
In right earnest, the Committee
submitted its report in August, 2011. If AERB is reaaly a fully empowered
regulator, NPCIL should have immediately submitted the time schedule for
implementing the 17 important measures suggested on the assumption that a
Fukushima-like disaster could take place and the system should be fully ready
to deal with such a cdisaster both onsite and offsite. These measures are not
to be taken lightly as otherwise the Committee would not have recommended
them. Without these measures, from what the Committee has stated in Para 4.1,
there will be a gap in the safety shield in the event of a Fukushima-like
meltdown. NPCIL's latest affidavit, filed on 16-10-2012 is still talking
about a phased implementation over several years of the ten residual measures
as though a Fukushima-like melt down will afford NPCIL and the public the
luxury of such a long lead time.
In a way, the casual manner in
which NPCIL is dealing with AERB Committee's recommendations demonstrates how
helpless is AERB as a regulator, which reports to Atomic Energy Commission
which is nothing but a component of the executive. C&AG's report on AERB
amply brought this out.
It is also relevant to cite here
that the Task Force (see para 7 of the latest NPCIL affidavit) submitted its
interim report on 11-5-2011. An interim report is meant to save time in view
of extreme urgency which existed in this case. Instead of acting fast, NPCIL
finalised the schedule of implementation on this on 7-5-2012, after the lapse
of one year! Apparently, NPCIL had not shown the same alacrity in acting
either on the Task Force's report or AERB Committee report, as in loading
fuel at Kudankulam.
Since the people's right under
Art. 21 is involved, this cannot be left to NPCIL's version of “safety”.
What about offsite disaster
preparedness? Has Tamil Nadu government constituted State and District level
DMAs as required the statutory NDMA? Are there contingent plans with
identified nuclear shelters, hospitals, doctors, their telephone numbers etc.
and have the people within 30km involved in simulating the implementation of
such contingency plans? We will touch upon this in the following paras.
|
9-10 (Independence of AERB)
|
Article 8 of IAEA's Convention on Nuclear Safety (see
para 9 of NPCIL's latest affidavit) clearly envisaged separation of
regulation from the agency that promoted nuclear energy. No such separation
either de facto or de jure exists in our case. The observations above have
demonstrated how AERB finds itself ineffective before DAE/ NPCIL. The latest
C&AG report clearly corroborated this.
|
11-13 (Spent fuel)
|
Retaining spent fuel in India was clearly an after
thought on the part of DAE/ NPCIL as otherwise NPCIL would have obtained
prior environment clearance from MOEF for Kudankulam complex on the basis
that spent fuel would be stored at plant site. There are serious environmental
and safety implications of storing the spent fuel as it happened at Fukushima
and elsewhere.
The Report of the committee appointed by Japanese
Parliament on Fukushima had this to say
“Units 1, 3 and 4 exploded, and the
containment vessel was breached in Unit 2. Core damage
was avoided in
Units 5 and 6, which shut down safely. The Commission discovered that,
in reality, an
even worse situation could have developed at Units 2 and 3, and the
situations at
Unit 5 and 6
could have easily worsened. If preventive measures against terrorist attacks
had
been
implemented, the accident might have been handled and developed in a
different way.
Damage to the
spent fuel of Unit 4 could have occurred, with greater affect to the wider
surrounding environment. There was a distinct potential at the time for this
disastrous accident
to result in an
even more frightening scenario.”
The above
Committee described spent fuel storage as one of the unresolved issues.
IAEA is seized
of the unresolved problem of spent fuel storage.
The US case law
corroborates this position.
|
14-44 (Environment clearances)
|
The earlier EC does not hold good as there has been a
basic alteration in the facilities at Kudankulam. Spent fuel storage has
serious environment implications. Under Environment (Protection) Act and the
regulations made thereunder, NPCIL was under an obligation to seek prior
EC for including spent fuel storage in the complex. In fact, NPCIL should
have got a cummulative EIA carried out and held a public hearing before
seeking an alteration in EC. In the absence of this, the project constitutes
an infringement of the law of the land.
Similarly, the EC did not envisage release of 320 CuM
per hour of water into the sea. Whether the quantity is small or large, it
has an impact on the marine resources. The temperature difference of 2
degrees is equally unauthorised as it was never envisaged.
|
45-48 (Liability)
|
The liability issue raised in this matter is different
from the one raised in the earlier PIL before SC. Here, the question is whether
the Liability law is applicable and, if not, does not “polluter pays”
principle apply? If there is no liability, does it not introduce a moral
hazard that would have encouraged the manufacturer to cut corners in design
and compromise safety
|
49-62 (Distater management)
|
NPCIL's affidavit did not answer the question on
offsite preparedness. NPCIL is not competent to say that offsite preparedness
as envisaged by NDMA has been ensured. It is for Tamil Nadu government to
file an affidavit.
Disaster preparedness is not paper preparedness. It is
an elaborate process, as envisaged by NDMA, that covers NPCIL, the State
govt, the local authorities, the local hospitals, the local logistics and the
people with information fully shared and the disaster mock drills simulated
several times over.
Para 89 of HC order is reproduced below
“Even
though it is stated that the said exercise was done in only one village,
namely Nakkaneri village, which is stated to be nearer to the KKNPP, as we
are informed that nearly 30 to 40 villages are within 30 Kms radius of KKNPP,
such event must take place in all villages and more importantly, apart from
the officials, as stated above, the people in the area must be made to
participate and an awareness programme must be made to infuse confidence in
the minds of the local people that the project is for the benefit of the
country and there is no need to alarm.”
Neither
NPCIL nor the State govt has complied with this
NDMA
itself prepared its disaster management guidelines in February, 2009. After
Fukushima, these guidelines should have been reviewed and made more
conservative. The fact that this has not been done demonstrates the casual
way in which our statutory agencies have viewed Fukushima. It is to be noted
that the PM chairs NDMA and heads DAE.

Comments on NPCIL’s Disaster
Management Plan
1.NPCIL’s Emergency preparedness plan
is limited by AERB only to 16km around the site, whereas the Madras High Court
order (para 89) referred to the need for preparedness up to 30km based upon
NEERI’s EIA impact zone.
2.
After Fukushima accident, the Disaster
Management Plan (DMP) Zoning limits have been reviewed and extended in several
countries. Japan itself increased its evacuation zone from 20km to 30km and
shelter the victims upto 40km. USA’s NRC has stipulated Impact Monitoring zone
(EPZ-II) up to 80km and US citizens residing near Fukushima were advised to
move away beyond 80km. IAEA’s guidelines too have prescribed a zoning system
that is yet to be adopted by NPCIL. The zoning limits depend on several local
factors also, such as the wind direction and velocity.
NPCIL should have
carried out Emergency Planning studies for different levels of severity of the
accident at Kudankulam out of the 7 levels formulated by IAEA and adopted the IAEA zoning system keeping in
view the worst case scenario. After Fukushima, NPCIL has not reviewed its
zoning system to ensure greater safety of the public, even though the Prime
Minister directed them to take action in the wake of the Fukushima explosion
and also the guidelines formulated by the
National Disaster Management Authority of India under the chairmanship
of Prime Minister.
3. NPCIL’s
DMP plan is inadequate as explained above and continues to be a paper plan with
little or no involvement of the local authorities and the public. For example,
have the local authorities identified the hospitals where the affected people
are required to get admitted? Are the public aware of the emergency numbers and
the hospital details? Have mock drills been conducted to promote public
awareness up to the zoning limit of 30km including more than 30 villages as
indicated by the Madras High Court at para 89 of its order? Has Tamil Nadu
government a budgetary provision to deal with the situation? Is the State aware
of the Fukushima-kind of liability (Rs.4 lakh crores till date) that would
devolve on the government in the event of an accident? NPCIL’s affidavit is
incomplete unless Tamil Nadu state government and the District Collector,
Tirunelveli also file the affidavits.
4.
NPCIL’s disaster preparedness plan is only a
paper plan. To cite one specific example, as per NPCIL’s plan, the local
Medical/ Health authorities are required to be ready to administer stable
iodine to neutralize harmful radioactive iodine ingestion by
providing Potassium Iodide tablets stored in the PHCs in the emergency area. If
a nuclear accident of Fukushima type were to take place on the day of the
hearing, will NPCIL vouchsafe to the court under oath that all PHCs have in
store sufficient number of Potassium Iodide tablets and are the people in the
emergency area aware that the tablets should be taken in for the purpose? Are
PHCs fully aware of the dosage? If the answers to these questions are in the
negative, the inevitable conclusion that one should reach is that neither NPCIL
nor Tamil Nadu is prepared to deal with the disaster. Fuel loading in such a
situation will amount to a highly irresponsible act.
- It is not unusual for governments to abandon even fully commissioned nuclear power plants in view of safety considerations. South Korea recently closed down two of its nuclear power projects after a complaint that some minor parts in the plant had questionable quality certification. (report enclosed). Several plants under construction have been abandoned due to fears about safety in countries like United States and Europe. Germany abandoned nuclear power in view of the apprehensions that arose after Fukushima. Japan has closed down many of its reactors. There is no reason as to why Kudankulam should not be stopped for a similar reason.
- NPCIL has placed the responsibility for offsite emergency preparedness on the local district authorities and the Tamil Nadu State Government. Unless Tamil Nadu government also files an affidavit that they have understood their scientific, technical, public health, environmental safety and financial responsibilities under the DMP plan and are fully geared to effectively implement the same, NPCIL's affidavit on safety cannot be accepted. Is TN government ready to discharge its responsibilities if the accident were to take place on the day the plant starts operating?
- NPCIL's DMP plan does not appear to have taken into account the worst case scenario of level 7as per international standards followed by IAEA. Can it therefore be accepted as complete and safety-ensuring measure taken in public interest?
- The DMP plan is merely a paper plan. Has DMP plan been simulated to the last detail and conducted the required emergency evacuation exercise as per specifications even once? Both NPCIL and TN government should file affidavits to say whether this has been done or not.
- Till these issues are satisfactorily answered, NPCIL should be directed to freeze Kudankulam fuel loading.
10.
NPCIL in its affidavit before the Supreme Court
on 16-10-2012 clearly admitted that the NPCIL proposed in its letter
dt.7-5-2012 that it will implement all the 17 recommendations made by the Task
Force committee by October-November 2012 and this fact is mentioned in the
Affidavit filed by the AERB on 27-9-2012 in Supreme Court under Annexure-R/8
covering pages 226-231. Unfortunately
the AERB created to promote nuclear safety has been playing the opposite role
by delaying the implementation of the safety measures which were demanded to be
implemented by the Prime Minister on 29-3-2011 in the wake of the Fukushima
disaster. All the 17 conditions are essential ones to be complied with prior to
fuel loading in order to ensure safety.
11.
AERB on 5-6-2012 before the Madras High Court
that it would grant further clearances only after ensuring implementation
of safety measures recommended by the
task force for strengthening the safety of Kudankulam Nuclear plant in the wake
of Fukushima disaster. But NPCIL brushes
aside the spirit of the assurance given by the AERB by saying that AERB never
meant that all the 17 recommendations to be implemented as a pre-requisite to
grant license for initial fuel loading of the reactors. While the Prime Minister is insisting that
there should be no compromise on the absolute safety of Kudankulam Nuclear
reactors the AERB and NPCIL by their statements appear to be promoting nuclear
safety but by their actions are actually working against nuclear safety by
planning to commission the nuclear reactors at the earliest while postponing
the implementation of the essential safety measures even by violating the
guidelines both on plant safety and public safety as envisaged by the standards
and guidelines specified by the National Disaster Mangement Authority (NDMA)
and the International Atomic Energy Agency (IAEA)
12.
The recommendations of the Task Force are not in
the nature of “abundant precautionary measures” or a back-up system to another
back-up system but are highly essential pre-requisites for ensuring nuclear
safety before starting the reactors because in most major industrial accidents
like Bhopal, more than half a dozen back-up systems failed and thereby created
major disasters involving the loss of thousands of lives. The recommendations
of the Task Force committee provided only a second line of defense to ensure more
reliable safety even when the first line of safety fails due to several reasons
like electrical or mechanical failures or human errors in operations,
vulnerabilities due to aging of the
instruments and equipment, internal sabotage and lack of close coordination
among the officers and workers involved in operation and maintenance. The task force recommendations and their
implementation must be considered as essential prerequisites for ensuring
higher reliability and nuclear safety.
I. Illegal
Environmental clearance for the KKNPP project:
1) Initially Kudankulam plant authorities applied for consent
for nuclear plant project in 1988 along with brief Environmental Impact
Assessment of KKNPP 1 and 2 as per Environmental Protection Act,
1986. In this first EIA report NPCIL
stated that from its 100 meters high stack it will discharge about 0.4 mSv of
radioactivity per year and also promised to let out the effluents from the waste treatment plant
before dilution to contain very small quantities of radioactivity in 200 cu.m
/day and the once through condensed cooling sea water of about 6 lakh cu.m per hour discharged into the sea
will contain negligible radioactivity
and with a temperature increase of 5oC.
2) The plant accommodates a design basis accident and the
radiation dosage will be limited to 100 mSv for whole body and 500 mSv for the
thyroid during an accident in the exclusion area and it will be during the
normal operations limited to 50 mSv per year for the plant workers and 1 mSv
per year for the common people.
3) Under the design safety features NPCIL emphasized that the
Kudankulam reactor will adopt the safety features of the defense in depth
approach which was described in terms of
3 levels of safety.
4) Under the topic on EIA the plant authorities emphasized
that the environmental impact of the nuclear plant will be assessed under
several categories including the “the potential impact due to the unlikely event of an uncontrolled
release from the nuclear plant reaching the public domain”.
5) Even under the tabulated data item-13
on Emergency preparedness the NPCIL stated that the draft proposal on off-site
emergency preparedness plans was already submitted to the Atomic Energy
Regulatory Board and it was also stated that under the statutory requirements
the stipulations made in the clearance documents by the central and state
Governments will be adhered to.
6) Based on this brief EIA report and
other documents the Union Ministry of Environment accorded Environmental
clearance for the Kudankulam nuclear plant on 9-5-1989 by stipulating firstly
that the temperature of the condensed water should not exceed 5oC
over and above the ambient temperature of the water at the point of discharge
into the sea. Secondly that the on-site and off-site disaster
management plan (DMP) should be prepared as per the guidelines stipulated by
ICRP/AERB and approved by the National Emergency Response Committee of the
Department of Atomic Energy, Government of India.
7) Unfortunately on a second
representation of the NPCIL dt. 7-8-2001 for grant of Environmental clearance
for this project the Union Ministry of Environment sent its officials to visit Kudankulam site
on 31-8-2001 and these officials were provided with false information that
construction work on the plant has progressed well and that the consent
conditions of the Environmental clearance letter dt.9-5-1989 were fulfilled and
as a consequence this misleading information the Union Ministry said that
“Keeping in view the steps already taken to implement the project, the
Environmental clearance issued in May, 1989 stands valid and there is no need to conduct public hearing and seek fresh
environmental clearance and hence granted revalidated on 6-9-2001 the original
environmental clearance for this project.
Since this revalidated environmental clearance is based on false data
and false information it becomes illegal null and void.
The
truth is that AERB did not accord permission for construction of this project
and the Tamil Nadu state Pollution Control Board also did not give any permission
for the construction of this project by this time. More over the stipulation made by the
Environmental Ministry that off-site disaster management plan should be
prepared by NPCIL was not fulfilled by August, 2001 and it was fulfilled only
on 4-1-2011 more than a decade later.
Yet the Union Ministry of Environment did not raise this relevant
questions and blindly revalidated on 6-9-2001 the original environmental
clearance letter of 9-5-1989.
II.AERB misinterprets recommendations of Task
Force Committee on Nuclear Safety:
1) AERB instead of working for nuclear
plant safety is promoting nuclear hazards to the detriment of public health and
Environmental Safety by misinterpreting the recommendation No.5 of the Task
Force committee report submitted in the wake of the Fukushima accident for
instance the recommendation No.5 deals
with “Finalization of Emergency Operating procedures for beyond design basis
accident conditions”. NPCIL treated
this as a short term measure for
implementation by merely stating “EOPs
for some PIEs have been made, remaining are in progress”.
2) The AERB in its Affidavit filed on 27-9-2012 before
the Supreme Court in SLP (Civil No.27335 of 2012) states that KKNPP is one of
the advanced reactors in the world having built in design features for beyond
design based accidents management.
Emergency operating procedures for all designed bassis accident have
been prepared and finalized. As and when the proposed safety enhancements are
incorporated the EOPs need to appropriately be formulated. Hence AERB recommended to NPCIL to address
this issue. It is also submitted here
that these procedures are for handling situations within the plant and are not
related to any off-site emergency for which separate approved emergency plans
are already inplace.”
This
assertion by AERB clearly shows that it is a body that is least interested in
promoting nuclear safety without compromising with the absolute safety of the reactors as directed by the
Prime Minister during the last week of March 2011 during a meeting attended by
the officials of the Department of Atomic Energy. Infact the United States Government directed
the US nuclear regulatory commission to appoint an expert committee to study
the Fukushima accident and to learn some lessons from this disaster so that
necessary remedial measures can be implemented to improve the safety of the
nuclear plants in USA. This Task Force
gave utmost importance for reviewing the existing emergency preparedness plans
in case of nuclear accidents both design- base and beyond-design-based
accidents. But the Indian nuclear
regulatory authority has taken an anti-public and anti-national stand in the
matter as can be seen in the following paragraphs.
I) US EXPERT COMMITTEE
RECOMMENDATIONS TO IMPROVE REACTOR SAFETY BASED ON THE LESSONS FROM FUKUSHIMA
ACCIDENT
The Near-Term Task Force was established in response to Commission
direction to conduct a systematic and methodical review of U.S. Nuclear
Regulatory Commission processes and regulations to determine whether the agency
should make additional improvements to its regulatory system and to make
recommendations to the Commission for its policy direction, in light of the
accident at the Fukushima Dai-ichi Nuclear Power Plant. The Task Force
appreciates that an accident involving core damage and uncontrolled release of
radioactive material to the environment, even one without significant health
consequences, is inherently unacceptable. The Task Force also recognizes that
there likely will be more than 100 nuclear power plants operating throughout
the United States for decades to come. The Task Force developed its
recommendations in full recognition of this environment.
In examining the Fukushima
Dai-ichi accident for insights for reactors in the United States, the Task
Force addressed protecting against accidents resulting from natural phenomena,
mitigating the consequences of such accidents, and ensuring emergency
preparedness.
The accident in Japan was
caused by a natural event (i.e., tsunami) which was far more severe than the
design basis for the Fukushima Dai-ichi Nuclear Power Plant. As part of its
undertaking, the Task Force studied the manner in which the NRC has
historically required protection from natural phenomena and how the NRC has
addressed events that exceed the current design basis for plants in the United
States.
In general, the Task Force
found that the current NRC regulatory approach includes:
• requirements for design-basis events with protection and
mitigation features controlled through specific regulations or the general
design criteria (Title 10 of the Code of Federal Regulations (10 CFR)
Part 50, “Domestic Licensing of Production and Utilization Facilities,”
Appendix A, “General Design Criteria for Nuclear Power Plants”)
• requirements for some “beyond-design-basis” events through
specific regulations (e.g., station blackout, large fires, and explosions)
• voluntary industry initiatives to address severe accident
features, strategies, and guidelines for operating reactors
This regulatory approach,
established and supplemented piece-by-piece over the decades, has addressed
many safety concerns and issues, using the best information and techniques
available at the time. The result is a patchwork of regulatory requirements and
other safety initiatives, all important, but not all given equivalent
consideration and treatment by licensees or during NRC technical review and inspection.
Consistent with the NRC’s organizational value of excellence, the Task Force
believes that improving the NRC’s regulatory framework is an appropriate,
realistic, and achievable goal.
The Task Force has found
that the defense-in-depth philosophy is a useful and broadly applied concept.
It is not, however, susceptible to a rigid definition because it is a
philosophy. For the purposes of its review, the Task Force focused on the
following application of the defense-in-depth concept:
• protection from external
events that could lead to fuel damage
• mitigation of the
consequences of such accidents should they occur, with a focus on preventing
core and spent fuel damage and uncontrolled releases of radioactive material to
the environment
• emergency preparedness
(EP) to mitigate the effects of radiological releases to the public and the
environment, should they occur
Finally, a new and dedicated
portion of the regulations would allow the Commission to recharacterize its
expectations for safety features beyond design basis more clearly and more
positively as “extended design-basis” requirements. The Task Force recognizes
fully that a comprehensive reevaluation and restructuring of the regulatory
framework would be no small feat. The Task Force also recognizes that
strengthening the roles of defense-in-depth and risk assessment, emphasizing
beyond-design-basis and severe accident mitigation, and establishing a clear,
coherent, and well-integrated regulatory framework would be a significant
accomplishment. Therefore, the Task Force concludes that additional steps would
be prudent to further enhance the NRC regulatory framework to encompass the
protections for accidents beyond the design basis. The Task Force
recommends
1)
establishing a logical, systematic, and coherent regulatory framework
for adequate protection that appropriately balances defense-in-depth and risk
considerations.
2) that the NRC require licensees
(operators) to reevaluate and upgrade as necessary the design-basis seismic and
flooding protection of SSCs (Structures, Systems and Components) for each
operating reactor.
3)
as part of the longer term review, that the NRC evaluate potential
enhancements to the capability to prevent or mitigate seismically induced fires
and floods.
4)
that the NRC strengthen SBO (Station Black Out) mitigation capability at
all operating and new reactors for design-basis and beyond-design-basis
external events (accidents).
5 )
requiring reliable hardened vent designs in BWR facilities with Mark I
and Mark II containments.
6) as part of the longer term review,
that the NRC identify insights about hydrogen control and mitigation inside
containment or in other buildings as additional information is revealed through
further study of the Fukushima Dai-ichi accident.
7 )
enhancing spent fuel pool makeup capability and instrumentation for the
spent fuel pool.
8 ) strengthening and integrating onsite
emergency response capabilities such as EOPs(Emergency Operating Procedures),
SAMGs, and EDMGs
9) that the NRC require that facility
emergency plans address prolonged SBO and multiunit events.
10)as part of the longer term review,
that the NRC should pursue additional EP (Emergency Preparedness) topics related to multiunit events and
prolonged SBO. (See explanation under Note-1)
11)
as part of the longer term review, that the NRC should pursue EP topics
related to decision making, radiation monitoring, and public education.
12) that the NRC strengthen regulatory
oversight of licensee safety performance (i.e., the ROP) by focusing more
attention on defense-in-depth requirements consistent with the recommended
defense-in-depth framework.
Note-1 : Currently, if a nuclear
power plant shuts down as a result of a natural disaster and the disaster is of
such severity that damage or changes to the offsite emergency response
infrastructure may be substantial or are in question, the NRC and FEMA determine
the status of offsite EP and coordinate approval of plant restart activities.
Evacuation time estimates
(ETEs) are used as a tool to (1) develop and improve evacuation plans in
advance of an accident and (2) to decide whether sheltering or evacuation is the
more protective response during an accident. Evacuation is preferred if a dose
in excess of protective action guides is probable, but it is not always more
effective in reducing public exposure. ETEs are a planning tool and do nothing
to affect conditions during an actual evacuation. Draft NUREG/CR-7002,
“Criteria for Development of Evacuation Time Estimate Studies,” issued May
2010, provides the latest guidance for licensees to develop a comprehensive set
of ETEs.
Infrastructure damage could
also affect the ability of licensees to bring equipment from offsite sources to
the site. The regulation in 10 CFR 50.47(b)(3) requires licensees to maintain
agreements with offsite organizations needed to support emergency response.
Typically, this includes local fire departments, law enforcement, and medical
support. As part of the requirements of 10 CFR 50.54(hh)(2)(i), licensees must
identify and seek readily available agreements for additional offsite resources
(both local and regional) that could support fire fighting, electrical power,
core cooling, and other needs.
The regulation in 10 CFR
50.47(b)(10) requires licensees to make protective action recommendations. To
facilitate a preplanned strategy for protective actions during an emergency,
two EPZs surround each nuclear power plant. The exact size and shape of each
EPZ is determined through detailed planning that includes consideration of the
specific conditions at each site, unique geographical features of the area, and
demographic information. This preplanned strategy for an EPZ provides a
substantial basis to support activity beyond the planning zone in the extremely
unlikely event it would be needed. The plume exposure pathway EPZ has a radius
of about 16 kilometers (10 miles) from the reactor site. Predetermined
protective action plans in place for this EPZ are designed to avoid or reduce
dose from potential exposure to radioactive materials. These action plans
include sheltering, evacuation, and the use of potassium iodide (KI) where
appropriate. The ingestion exposure pathway EPZ has a radius of about 80
kilometers (50 miles) from the reactor site. Predetermined protective action
plans in place for this EPZ are designed to avoid or reduce dose from the
potential ingestion of radioactive materials. These action plans include a ban
of contaminated food and water.
NUREG-0396, “Planning Basis
for the Development of State and Local Government Radiological Emergency
Response Plans in Support of Light Water Nuclear Power Plants,” issued December
1978, establishes the concept and basis for the 10-mile and 50-mile EPZs,
describes the basis for the types of reactor accidents that should be
considered in an emergency plan, states that emergency planning is not based on
probability but on public perceptions of the problem and what could be done to
protect public health and safety (as a matter of prudence rather than
necessity), and concludes that the objective of an emergency plan should be to
provide dose savings for a spectrum of accidents that could produce offsite doses
in excess of the U.S. Environmental Protection Agency’s (EPA’s) protective
action guides.
During the emergency at
Fukushima, conditions deteriorated such that Japanese officials required
additional protective actions up to and beyond a 20-kilometer (16-mile) area
around Fukushima (i.e., beyond the equivalent of the U.S. plume exposure
pathway EPZ). The possibility of making protective action recommendations for
areas beyond the plume exposure pathway EPZ has been a program consideration
since the inception of the EPZ concept in the United States. The emergency
planning basis for U.S. plants, as discussed in NUREG-0654, states, “…detailed
planning within 10 miles would provide a substantial base for expansion of
response efforts in the event that this proved necessary.” NUREG-0654 goes on
to state that it would be unlikely that any protective actions for the plume
exposure pathway would be required beyond the plume exposure pathway EPZ. It
further stated that the plume exposure EPZ is of sufficient size for actions
within this zone to provide for substantial reduction in early severe health
effects (injuries or deaths) in the event of a worst case core melt accident
Note-2 :
Basis for Japanese authorities to
decide for evacuating People from
Fukushima reactor site upto 30km and
sheltering people upto 40km and beyond due to the accident:
Currently
evacuation zones are defined on the basis of the expected exposure of the
public to radiation (in millisieverts, mSv). In Japan, the reference level is
20 mSv per year. This means that if members of the public are expected to
receive more than a 20 mSv dose in a year they must be evacuated.
Following the accident, the Japanese government chose these criteria based on
the latest recommendations of the International Commission on Radiological
Protection (ICRP).
In
the event of an accident, for most nuclear power plants around the world, it is
expected that people located within a 5 km radius will be evacuated. At
Fukushima Daiichi, the evacuation zone was 20 km and in some circumstances
out to 30 km.
Note-3: US GOVERNMENT ORDERS REVIEW OF NUCLEAR SAFETY
BASED ON FUKUSHIMA:
CHARTER
FOR THE NUCLEAR REGULATORY COMMISSION TASK FORCE TO CONDUCT A NEAR-TERM
EVALUATION OF THE NEED FOR AGENCY ACTIONS FOLLOWING THE EVENTS IN JAPAN Objective
The objective of this task force is to conduct a methodical and systematic
review of relevant NRC regulatory requirements, programs, and processes, and
their implementation, to recommend whether the agency should make near-term
improvements to our regulatory system. This task force will also identify a
framework and topics for review and assessment for the longer-term effort.
Scope The task force review will include the following: a. A near-term review
to:
• Evaluate currently available technical
and operational information from the events that have occurred at the Fukushima
Daiichi nuclear complex in Japan to identify potential or preliminary
near-term/immediate operational or regulatory actions affecting domestic
reactors of all designs, including their spent fuel pools. The task force will
evaluate, at a minimum, the following technical issues and determine priority
for further examination and potential agency action:
•
External event issues (e.g. seismic, flooding, fires, severe weather)
• Station blackout
• Severe accident measures (e.g.,
combustible gas control, emergency operating procedures, severe accident
management guidelines)
• 10 CFR 50.54 (hh)(2) which states, “Each
licensee shall develop and implement guidance and strategies intended to
maintain or restore core cooling, containment, and spent fuel pool cooling
capabilities under the circumstances associated with loss of large areas of the
plant due to explosions or fire, to include strategies in the following areas:
(i) Fire fighting; (ii) Operations to mitigate fuel damage; and (iii) Actions
to minimize radiological release.” Also known as B.5.b. • Emergency
preparedness (e.g., emergency communications, radiological protection,
emergency planning zones, dose projections and modeling, protective actions)
• Develop recommendations, as appropriate,
for potential changes to NRC’s regulatory requirements, programs, and
processes, and recommend whether generic communications, orders, or other
regulatory actions are needed.
b.
Recommendations for the content, structure, and estimated resource impact for
the longer-term review. Coordination and Communications The near-term task
force will:
•
Solicit stakeholder input as appropriate, but remain independent of industry
efforts.
•
Coordinate and cooperate where applicable with other domestic and international
efforts reviewing the events in Japan for additional insights.
• Provide recommendations to the Commission
for any immediate policy issues identified prior to completion of the near-term
review.
•
Provide recommendations to program offices for any immediate actions not
involving policy issues, prior to completion of the near-term review.
• Identify resource implications of near-term
actions.
•
Consider information gained from Temporary Instruction 2515/183, “Followup to
the Fukushima Daiichi Nuclear Station Fuel Damage Events.”
• Develop a communications plan.
•
Update and brief internal stakeholders, as appropriate. Expected Product and
Schedule The task force will provide its observations, conclusions, and
recommendations in the form of a written report to the Deputy Executive
Director for Reactor and Preparedness Programs at the completion of the 90-day
near-term review. During the development of its report, the task force will
brief the Commission on the status of the review at approximately the 30- and
60-day points. The report will be transmitted to the Commission via a SECY
paper, and the task force will brief the Commission on the results of the
near-term effort at approximately the 90-day point. The report will be released
to the public via normal Commission processes. The task force will recommend a
framework for a longer-term review as a part of the near-term report. The
longer-term review will begin as soon as the NRC has sufficient technical
information from the events in Japan (with a goal of beginning by the end of
the near-term review).
Appendix C Staffing The task force will consist of the following members:
Leader Charles Miller FSME Senior Managers Daniel Dorman NMSS Jack Grobe NRR
Gary Holahan NRO Senior Staff Amy Cubbage NRO Nathan Sanfilippo OEDO
Administrative Assistant Cynthia Davidson OGC Additional task force members
will be added as needed. For the near-term review, other staff members may be
consulted on a part-time basis. EDO Interface The task force will keep agency
leadership informed on the status of the effort and provide early
identification of significant findings. The task force will report to Martin J.
Virgilio, Deputy Executive Director for Reactor and Preparedness Programs.
NUCLEAR SAFETY IS BASED ON DEFENCE INDEPTH
CONCEPT INCLUDING DISASTER MANAGEMENT PLAN (DMP) IN CANADA
The
concept of defence-in-depth is applied to all organizational, behavioural, and
design-related safety and security activities to ensure that they are subject
to overlapping provisions. With the defence-in-depth approach, if a failure
were to occur it will be detected and compensation made, or it would be
corrected.
This
concept is applied throughout the design process and operation of the plant to
provide a series of levels of defence aimed at preventing accidents, and
ensuring appropriate protection in the event that prevention fails.
The
design provides all five levels of defence during normal operation; however,
some relaxations may be specified for certain shutdown states. These levels are
introduced in general terms below, and are discussed in greater detail in subsection 6.1.
6.0 Safety Considerations
Defence-in-depth
is achieved at the design phase through application of design provisions
specific to the five levels of defence.
Level One
Achievement
of defence-in-depth level one calls for conservative design and high-quality
construction to provide confidence that plant failures and deviations from
normal operations are minimized and accidents are prevented.
This
entails careful attention to selection of appropriate design codes and
materials, design procedures, equipment qualification, control of component
fabrication and plant construction, and use of operational experience.
Level Two
Defence-in-depth
level two is achieved by controlling plant behaviour during and following a PIE
using both inherent and engineered design features to minimize or exclude
uncontrolled transients to the extent possible.
Level Three
Achievement
of defence-in-depth level three calls for provision of inherent safety
features, fail safe design, engineered design features, and procedures that
minimize the consequences of DBAs. These provisions are capable of leading the
plant first to a controlled state, and then to a safe shutdown state, and
maintaining at least one barrier for the confinement of radioactive material.
Automatic activation of the engineered design features minimizes the need for
operator actions in the early phase of a DBA.
Level Four
Defence-in-depth
level four is achieved by providing equipment and procedures to manage
accidents and mitigate their consequences as far as practicable.
Most
importantly, adequate protection is provided for the confinement function by
way of a robust containment design. This includes the use of complementary
design features to prevent accident progression and to mitigate the
consequences of selected severe accidents. The confinement function is further
protected by severe accident management procedures.
Level Five
The
design provides an adequately equipped emergency support centre, and plans for on-site and
off-site emergency response.
To
ensure maintenance of the overall safety concept of defence-in-depth, the
design provides multiple physical barriers to the uncontrolled release of
radioactive materials to the environment. Such barriers include the fuel
matrix, the fuel cladding, the reactor coolant pressure boundary, and the
containment. In addition, the design provides for an exclusion zone.
To
the extent practicable, the design therefore prevents:
Challenges
to the integrity of physical barriers;
Failure
of a barrier when challenged; and
Failure
of a barrier as a consequence of failure of another barrier.
The
design also allows for the fact that the existence of multiple levels of
defence is not a sufficient basis for continued power operation in the absence
of one defence level.
NRC
PROVIDES PROTECTIVE ACTION RECOMMENDATIONS BASED ON U.S. GUIDELINES
Under the guidelines for public safety that
would be used in the United States under similar circumstances, the NRC believes
it is appropriate for U.S. residents within 50 miles of the Fukushima reactors
to evacuate.
Among
other things, in the United States protective actions recommendations are
implemented when projected doses could exceed 1 rem to the body or 5 rem to the
thyroid. A rem is a measure of radiation dose. The average American is exposed
to approximately 620 millirems, or 0.62 rem, of radiation each year from
natural and manmade sources.
In
making protective action recommendations, the NRC takes into account a variety
of factors that include weather, wind direction and speed, and the status of
the problem at the reactors.
Attached
are the results of two sets of computer calculations used to support the NRC
recommendations.
In response to nuclear emergencies, the NRC works with other
U.S. agencies to monitor radioactive releases and predict their path. All the
available information continues to indicate Hawaii, Alaska, the U.S.
Territories and the U.S. West Coast are not expected to experience any harmful
levels of radioactivity.

and the event was participated by not only the officials of the NPCIL
and Department of Atomic Energy, but also AERB.
Even though it is stated that the said exercise was done in only one
village, namely Nakkaneri village, which is stated to be nearer to the KKNPP,
as we are informed that nearly 30 to 40 villages are within 30 Kms radius of
KKNPP, such event must take place in all villages and more importantly, apart
from the officials, as stated above, the people in the area must be made to
participate and an awareness programme must be made to infuse confidence in the
minds of the local people that the project is for the benefit of the country
and there is no need to alarm.

A design outcome could be
spending proportionately more on protecting those systems, the consequence of
failure of which to an external event would be more serious. However, to an
extent
this is already done by the
application of more rigorous design codes to such items.
The hierarchy of Westinghouse
PWR Safety Critical Functions could be adopted as a practical implementation of
the aspiration for safety significance given in paragraph 3.13 of reference
[3.8]:
Safe shutdown;
Safe hold-down;
Safe decay heat removal;
Safe containment;
Safe cooling of spent fuel.
