Kudankulam Nuclear Power Plant is a nuclear power station in Koodankulam in the Tirunelveli district of the southern Indian state of Tamil Nadu. Construction on the plant began on 31 March 2002, but faced several delays. Long construction times for nuclear reactors are common in India, but this delay was partly due to the 500-day-long anti-nuclear protests by local residents, led by the People's Movement Against Nuclear Energy (PMANE).
Unit 1 was synchronized with the southern power grid on 22 October 2013. The original cost of the two units was 13,171 crore, but it was later revised to 17,270 crore. Russia advanced a credit of 6,416 crore to both the units.
An Inter-Governmental Agreement (IGA) on the project was signed on 20 November 1988 by then Prime Minister Rajiv Gandhi and then Soviet head of state Mikhail Gorbachev, for the construction of two reactors. The project remained in limbo for a decade due to the dissolution of the Soviet Union. There were also objections from the United States, on the grounds that the agreement did not meet the 1992 terms of the Nuclear Suppliers Group (NSG). M.R. Srinivasan, Atomic Energy Commission (AEC) Chairman from 1987 to 1990, called the project "a non-starter". However, the project was revived on 21 June 1998.
Construction began on 31 March 2002, with Nuclear Power Corporation of India Ltd. (NPCIL) predicting that the first unit would be operational in March 2007, instead of the original target of December 2007.
A small port became operational in Kudankulam on 14 January 2004. This port was established to receive barges carrying over sized light water reactor equipment from ships anchored at a distance of 1.5 kilometres (0.93 mi). Until 2004, materials had to be brought in via road from the port of Tuticorin, risking damage during transportation. In 2008, negotiations on building four additional reactors at the site began. Though the capacity of these reactors has not been declared, it was expected that the capacity of each reactor will be 1200 MW or 1.2 GW. The new reactors would bring the total capacity of the power plant to 6800 MW or 6.8 GW.
The first reactor of the plant attained criticality on 13 July 2013 at 11:05 pm.
A healthy growth in fauna, particularly birds, has been observed around the Kudankulam plant. This is due to measures taken to enhance green cover around the nuclear plant.
Design and specification
Two 1 GW reactors of the VVER-1000 model are being constructed by the NPCIL and Atomstroyexport. When completed they will become the largest nuclear power generation complex in India producing a cumulative 2 GW of electric power. Both units are water-cooled, water-moderated power reactors.
The reactor was to begin supplying power to the Central Grid by end of August 2013.
The Kerala State Electricity Board (KSEB) board members have approved signing of a power purchase agreement (PPA) with the Nuclear Power Corporation of India (NPCIL) for sourcing electricity from the Kudankulam nuclear power project (KKNPP).
KKNPP was first synchronized to grid at 2:45 am on 22 October 2013. Power generation from first nuclear reactor started on the same day. Unit-1 was operating at 73% capacity (680 MW) by April 2014. Unit 1 attained its maximum capacity of 1,000 MWe at 1:20 pm on 7 June 2014. The unit 1 started commercial operation from 31st Dec 2014
In 2011, thousands from the vicinity of the plant protested against it, fearing a nuclear disaster. According to the protesters, evacuation of people in the event of a nuclear disaster would be impossible. According to S P Udayakumar, of the People's Movement Against Nuclear Energy, "the nuclear plant is unsafe". However, in 2012, the chief of India's nuclear energy program, Dr Srikumar Banerjee, called the plant "one of the safest" in the world. In December 2012, The Hindu reported that hundreds of villagers in the region were largely ignorant of the risks and benefits of the plant.
A Public Interest Litigation (PIL) was filed in 2011 with the Supreme Court asking for nuclear power development to be delayed until safety concerns were independently assessed. In May 2013, the Supreme Court ruled in favour of the plant, stating that the nuclear power plant was in the larger public interest.
In March 2012, nearly 200 anti-nuclear protesters were detained for a few hours by the police. The protesters were set to join protests objecting resumption of work of one of two 1 GW reactors, a day after the local government restarted work on the project.
On, 24 February 2012, Prime Minister Manmohan Singh blamed foreign NGOs for protests at the power plant. News agencies reported that three NGOs had diverted donations earmarked for religious and social causes to the protests, in violation of foreign exchange regulations.
Response from officials
Former chairman of Atomic Energy Commission of India Srinivasan said, "The Fukushima plant was built on a beachfront, but the Kudankulam was constructed on a solid terrain and that too keeping all the safety aspects in mind. Also, we are not in a tsunami prone area. The plants in Kudankulam have a double containment system which can withstand high pressure. At least Rs.14,000 crore has been spent. If we don't operate the plant immediately, it will affect the economic stability of our country".
A centre panel constituted by the Government of India, which did a survey of the safety features in the plant, vouched for the safety of the Kudankulam reactors. Dr. Muthunayagam, who headed the panel, said that the protesters asked for some documents which are not related to the safety of the reactor. Nuclear scientist and principal scientific adviser to the federal Government of India Rajagopala Chidambaram has said “We have learnt lessons from the Fukushima nuclear accident, particularly on the post-shutdown cooling system,” and also added Fukushima nuclear accident should not deter or inhibit India from pursuing a safe civil nuclear program.
The Tamil Nadu state government formed a four-member expert panel which submitted a report to the government after inspecting the safety features of the plant. The Tamil Nadu government in the wake of the acute power shortages in the state has ordered in favour of the commissioning of the plant.
Allocation of power
Government of India announced the power allocation from the 2 units of the reactor on Aug 29, 2013
|Tamil Nadu||925 MW|
|Not allocated||300 MW|
Tamil Nadu may get another 100 MW over its allocation.
