Koodankulam Update: Reaching Criticality

Statement from the Coalition for Nuclear Disarmament and Peace:

In a shocking development, Nuclear Power Corporation of India Ltd has announced that the first nuclear reactor at Koodankulam in Tamil Nadu has reached criticality, or the beginning of a fission chain reaction.

This is an important step in the plant’s commissioning and towards making the fission process irreversible. But it violates the spirit of the Supreme Court’s May 6 order, which asked that NPCIL, the Atomic Energy Regulatory Board, Ministry of Environment and Forests and Tamil Nadu Pollution Control Board “oversee each and every aspect of the matter, including the safety of the plant, impact on environment, quality of various components and systems in the plant before commissioning of the plant. A report to that effect be filed before this Court” prior to its commissioning.

Implicit in the order is not just the formal filing of such a report, but its perusal and approval by the Supreme Court. However, the agencies concerned merely filed the report in a sealed envelope, but the Court confirmed on July 15 that it has not even seen, let alone approved, the report.

This is part of a pattern followed by the nuclear establishment in cutting corners and bypassing essential procedures in matters of safety. It amounts to a breach of public trust, ans shows contempt for democratic and judicial processes.

The Koodankulam reactor was made critical despite the massive and sustained peaceful popular protests against the plant, and despite numerous warnings by nuclear experts, including former AERB chairman A Gopalakrishnan, about the plant’s vulnerability to hazards and the use of substandard equipment supplied by Russian company Zio-Podolsk.

This is profoundly anti-democratic and totally unacceptable. Ironically, the Koodankulam reactor reached criticality on the same day that China bowed to public protest by announcing the abandonment of a nuclear processing project in the Southeast.

We demand that the commissioning of the Koodankulam reactor be immediately halted and an independent safety review be initiated at the earliest into the plant.

The authorities must revoke the criminal charges filed against the protesters in Koodankulam with immediate effect in keeping with the Supreme Court’s order.

Summary from Koodankulam Criticality: Tickling the Dragon’s Tail, Dianuke: 

The Commissioning of the first VVER-1000 reactor at Kudankulam Nuclear Power Plant [KKNPP] has been delayed by 66 months. According to a report dated 19 June 2013 by Dr A Gopalakrishnan, formerly Chairman of the Atomic Energy Regulatory Board [AERB], the instrumentation and control cables in the reactor are giving out spurious signals which is the operator’s main headache now. KKNPP’s Station Director had appointed a committee of scientists to clarify this issue. The clarification has not been given so far. Instead, the authorities have decided to go for the first act of criticality [FAC]. There are eight other reactors in the world – 6 in South Korea and 2 in the Czech Republic, which have had cable-related problems. The problems in the Korean reactors have been due to counterfeit cables which the Korean regulator has decided to replace. Studies have shown that the KKNPP reactors have counterfeit equipment such as the reactor pressure vessel, polar cranes and safety-class valves. Taking the reactor to FAC without clarifying the safety issues is a high risk operation.
