Scientists' letter to CMs voicing concern over Koodankulam equipment

The following is a letter written by a group of scientists to the Chief Ministers of Tamil Nadu and Kerala expressing their concern about the use of substandard components in ooudankulam Nuclear Power Plant 1 & 2, and the revelation at this late stage that four valves in a critical safety system were found defective:


To: Hon'ble Chief Minister
Government of Tamil Nadu
Secretariat, Chennai 600 009;

To: Hon'ble Chief Minister
Government of Kerala
Secretariat, Thiruvananthapuram 695001
Copy: Prime Minister's Office
South Block, Raisina Hill, New Delhi 110011
                                                      Date: 14th of May 2013
Respected Chief Ministers:
We, the below-signed, are scientists from various disciplines who are concerned about the quality of components and equipment used at the Koodankulam Nuclear Power Plant (KKNP) Units 1 & 2. Our concerns arise from recent media reports about the use of substandard components in KKNP 1 & 2, and the revelation at this late stage that four valves in a critical safety system were found defective.

These safety concerns are compounded by the fact that Russian authorities arrested Mr. Sergei Shutov, procurement director of Zio-Podolsk, on corruption charges for having sourced cheaper sub-standard steel for manufacturing components that were used in Russian nuclear installations in Bulgaria, Iran, China and India.  This has led to several complaints of sub-standard components and follow-up investigations in Bulgaria and China. The ramifications of such corruption need to be taken very seriously as they have implications on the long-term safety of the nuclear plant.

As the Chief Ministers of the states hosting and neighbouring the nuclear power plant, the two of you have a responsibility to satisfy yourself and the residents of Tamil Nadu and Kerala that the plant has been constructed to the highest safety standards. Any exercise to assure oneself of the quality of components used will have to be done before the plant is commissioned. Once commissioned, the radioactive environment in sections of the plant will make it impossible to access and test some potentially critical components.

Unfortunately, as we have seen in Fukushima, there is the danger that the impact of a major hazardous event in Koodankulam may not be localized but could spread to larger regions in both Tamil Nadu and Kerala. To reduce such a risk, in the light of recent revelations, we believe that it is important to have a fresh independent and thorough quality inspection of the components used in the two reactors.

We, the below-signed, include scientists who believe that nuclear energy has a legitimate role in securing our energy future and others that believe that nuclear energy is too risky. Through this letter, we are not advocating for or against nuclear energy. All of us are of the opinion that when dealing with complex and potentially dangerous technologies transparency, honesty and a rigorous adherence to the highest quality standards are imperative.   Even the Supreme Court's recent judgment has emphasized the need to ensure the quality of components and systems before operationalising the plant.

We urge you to convey to the Prime Minister and the Department of Atomic Energy that before commissioning the reactors, they should consult independent national experts to formulate an inspection regime and carry out a full-fledged inspection into the safety of KKNP 1 & 2. Such an inspection should pay particular attention to the allegations of sub-standard equipment and components.
