Your Excellency:

Greetings! We, the Expert Team of the People’s Movement Against Nuclear Energy (PMANE) has met today at Kanyakurmari and confirms the worst fears of the people that the Nuclear Power Corporation of India (NPCIL) has compromised on safety and failed to perform statutory due diligence. Citing the responses on the matter of siting and the issue of fresh water supply – both critical components in determining safety of the plant – we confirm that NPCIL has compromised on both these aspects.

May we bring your kind attention to the following issues:

1. The Koodankulam site is not only prone to small-volume volcanic eruptions, but also to mega-tsunamis with heights exceeding 100 feet, arising out of the presence of two large “slumps” in the seabed of Gulf of Mannar less than 100 km from the plant. A 1982 study in a noted journal documents the presence of two slumps — the East Comorin slump and the Colombo slump — in the vicinity of the Koodankulam site. The second report by the Central Govt expert committee has accepted the presence of the slumps and the possibility of a Near Field Tsunami occurring out of a landslide. This is in opposition to their earlier position and also to the position of AERB that Near field Tsunamis are not possible in India. However their contention is on the height Tsunami waves. While welcoming their change in accepting the possibility of near field Tsunami the PMANE Expert Team wishes to state that after the 1982 study, a Tsunami has occurred in DEC 2006 and the possibility of the Slump having changed it structure. Hence merely answering the question from the 1982 text is not sufficient.

2. PMANE’s Expert Team is alarmed that NPCIL has allowed the siting of the plant in an area characterised by sub-volcanic intrusions – an indication of volcanism in the near vicinity of the plant. The presence of sub-volcanic intrusions of the kind found in the KKNPP site is precisely the reason why the US Government abandoned the Yucca Mountain site as a possible waste storage site owing to concerns about the structural integrity. In addition to this small volume volcanic eruptions have occurred in the site vicinity from the year 1998.

3. Studies by ONGC, the Geological Survey of India and numerous other terrestrial and marine geologists confirm the presence of basaltic intrusions into the crust and the Gulf of Mannar seabed. Their findings tell us that the Gulf of Mannar sea bed has been thinned because of this. Its thickness is a mere 1,000 to 5,000 metres instead of average 40,000 metres for continental crust.

4. Scientists from National institutes have published as late as 2010 that the crustal thickness of koodankulam site is much thinner than the Gulf of Mannar Crust because of similar sub-volcanic intrusions. Ground Magnetic Survey conducted by them have suggested that the Crustal thickness is a mere 150 to 200 metres at koodankulam site.

5. The entire koodankulam region is known for its lime stone formations. Lime stone formations are known to the formation of Sink holes and underground caves. Events that have occurred in Nov 26, 2011, 2008, 1998 at Pannaiyarkulam, Radhapuram both located 10kms from the site and Maruthankulam (25kms) have suggested that this is a “KARST” Region. AERB’s safety laws clearly state that if a Karst region is suspected a detailed study has to be conducted. Such a study has not been attempted by NPCIL.

6. During 2004 Tsunami the withdrawal of the sea was around 4-5 Kms from the shore. Every year after this Tsunami, the some places of the coast of Tamilnadu has faced the issue of Sea water withdrawal at least 3 times a year. Tsunami hazard manual released by USNRC in March 2009 states that if sea water withdrawal is an issue at the site then the chances of the reactor going in for a dry intake should be studied thoroughly. Dry intake can cause damage to the turbines and reactors. Each minute a reactor needs 5,000 cubic-metres of sea water. Hence a detailed volcanic hazard study, Tsunami hazard study and a study about the “Karst” Terrain is a must.

7. Another crucial failure of NPCIL is the fact that the plant has assured supply of freshwater for merely 36 hours and 25 minutes. The dependence on a single source, namely, the desalination plant further reduces the reliability of this water source as desalination plants rely on the sea and electricity and can be disrupted both by disturbances in electricity supply and cyclones and extreme weather events in the sea along with Jelly fish intrusions. In such a situation reactors will have to be closed down immediately and the have just enough water for maintaining the safety systems for 10 days. The reserve of potable water for the KKNPP Township is sufficient for 2 days. The seawater intake pipeline of the Minjur desalination plant in Thiruvallur district was uprooted in 2008 during the Cyclone Nisha. Repairing the pipeline required engineers from the Netherlands and took more than 45 days.

8. Department of Atomic energy (DAE) funded study conducted by Dr. Manjula Datta has found that the Morbidity burden in the proximity villages of Kalpakkam is 400% higher than in distant villages. The diseases include Cancer, mental retardation, thyroid problems, infertility, lumps, stroke, cataract, TB, ulcer and diabetes. Another study conducted by Dr. Pugazhendhi et. al. showed that auto immune thyroid disease among women living in upto 40kms from the Kalpakkam site was significantly higher than those living 500kms away. In another study conducted by same doctor on 2003 among employees and family members had shown that the death rate due to Multiple Myloma (A bone marrow cancer) is statistically significant. Studies based on data supplied by NPCIL shows that the prevalence of cancer in workers and wives of BARC and TAPS is significantly higher than that found in MAPS. The first 2 reactors became critical during 60’s and 70’s whereas MAPS came critical during 1984-85. Yet another study shows significant deviation in sex-ratio of children born to employees of BARC & TAPS which is indicative of genetic mutations.

9. The USA and Japan have compensatory laws for employees as well as people living around the plants. (Energy employees occupational illness compensation program act) that too when the reactors function normally without any leaks or accidents. This clearly shows that Low level Radiation from the reactors is a health hazard.

10. We would like to submit that the airports in European Union banned the usage of X-rays due to the hazards of low level radiation. We would like to submit that there is no safe dose in radiation.

11. We would also like to submit that the de-commissioning cost of the reactors is not taken into account and the cost is at least few times higher than the commissioning cost. In Fukushima it has been estimated that it will cost 75,000 crores and 30 years to de-commission the failed nuclear plants. Taken this into account all the nuclear plants are unviable and un-economical.

12. The issue of spent fuels disposal is an unsolved issue both in terms of technology and economics and spent fuel will remain highly radioactive for 1000’s of years.

13. Energy efficiency and alternatives will give a sustainable energy solution. Energy efficiency measures in electricity will free up enough electricity to meet all present demands.

14. We would request the Honourable TN CM to take up the generation of electricity using renewable energy sources like Solar, Wind and excess bio-mass which are available in plenty in Tamil Nadu on a war-footing as was done in the case of rain water harvesting.

15. We would also like to request to implement the distributed renewable energy system and institute proper policies as was done for grid connected renewable energy generation. Tamil Nadu has got a greater potential for solar energy (25-30MW per sq.Km) and 300 cloud free days and establish Tamil Nadu as the pioneer in Renewable energy in India coinciding with the “International Year of Sustainable energy for all.”

Given this situation, we would very much like to request you to grant us an opportunity to meet with you and explain our reservations to the implementation of the KKNPP project. We would also like to request you to bring up the above issues with the Central Government and the Department of Atomic Energy and persist with your concern for the wellbeing of the people of Tamil Nadu.
