Reactors for Koodankulam

RUSSIA is to supply two more 1,000 MWe VVER-1000 nuclear power reactors for the Koodankulam Atomic Power Project (KAPP) in Tirunelveli district in Tamil Nadu. Construction of two reactors of the same specification purchased earlier from Russia is already on. Koodankulam will thus have four Russian reactors. The plant has the capacity to accommodate a total of eight units. The Russian reactors will use enriched uranium as fuel, and light water as coolant and moderator.

Russia lobbied hard for the supply of these additional reactors. At the first pour of concrete for the first two units that took place on March 31, 2002, (Frontline, April 26, 2002) E.A. Reshetnikov, the Russian Deputy Minister for Atomic Energy, presented Russia's case for building more reactors. But the Department of Atomic Energy (DAE) did not respond to the overtures immediately. Nuclear Power Corporation of India Limited (NPC) was prepared to construct reactors of 700 MWe or 1,000 MWe capacity if the Russian offer was not commercially viable. Finally, an agreement was reached by late 2002 on the supply of two additional reactors.

An announcement on the deal was to be made when Russian President Vladimir Putin visited New Delhi in the first week of December 2002, informed sources said. It was , however, not made considering the "international sensitivities" on nuclear-related sales. The United States has consistently opposed Russia supplying nuclear reactors to India on the grounds that the latter is not a signatory to the Nuclear Non-Proliferation Treaty (NPT). The Nuclear Suppliers Group (NSG), of which Russia is a member, also asked the latter not to supply reactors to India. What stood in India's favour is that it is not considered a nuclear proliferator, sources pointed out. The safety record of India's reactors is considered good. India has also respected the voluntary moratorium after the five nuclear tests conducted in May 1998 at Pokhran, Rajasthan.

While Russia will provide the reactor design and supply equipment such as reactor vessels, turbines, steam generators and so forth, NPC will build the two units. A contract was signed between NPC and the Russian company Atomstroyexport in Moscow in February 2002 for the supply of equipment.

At a press conference in Chennai on March 20, S.K. Jain, executive director (Light Water Reactors), NPC, said that there was speedy progress in the construction of the first two units. "We have signed contracts with the Russians for Rs.8,000 crores" for the supply of equipment, Jain said. Most of the equipment was in advanced stages of fabrication . "The main core of the reactor, which was to arrive in 2005, will arrive in 2004 itself," Jain said. According to him, the first unit will start generating electricity four and half years from now. The second unit will go critical six months later.

S.K. Agrawal, project director of the KAPP, said that 98 per cent of those recruited so far at the project were from Tamil Nadu. "Quite a good number of them belong to local areas. This for both technical and non-technical jobs," he said. Those who gave land for the project have been provided with jobs. Thousands of saplings have also been planted on the 420-hectare site.

S.A. Bohra, senior executive director (technical), NPC, said that the Centre had given financial approval for the construction of two reactors of 1,000 MWe each and two reactors of 700 MWe each in the Tenth Plan. He added that the Centre may approve construction of two more 1,000 MWe and another two 700 MWe reactors. According to Bohra, no more 220 MWe Pressurised Heavy Water Reactors (PHWRs) will be built. All future indigenous PHWRs will be of 700 MWe or 1,000 Mwe. Nine reactors are under construction. They include four PHWRs of 220 MWe (two each at Rawatbhatta in Rajasthan and Kaiga in Karnataka), two indigenous PHWRs of 540 MWe each at Tarapur in Maharashtra, two Russian units at Koodankulam, and the 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam in Tamil Nadu. Pre-project activities of the PFBR were in full swing, he added. Fourteen reactors are generating 2,720 MWe in the country now.

Koodankulam project delay led to power shortage

CHENNAI: The failure to commission the Koodankulam nuclear power project on time has led to the present power shortage in Tamil Nadu, S. Machendranathan, Chairman of the Tamil Nadu Electricity Board, said on Saturday.

Delivering the keynote address at a seminar, he said: “We have 2-4 per cent power shortage. But this should not deter us. The shortage could have been met, if the Koodankulam project was commissioned on time. However, in the past two years, there has been a tremendous increase in power demand, for which we have not done any planning.”

Soon after taking over the reins in November, Mr. Machendranathan had discussions with Board officials to bring down the peak load at summer. It was projected that the State might fall short of 400 MW, and he suggested that industrial units stagger holidays to meet the shortage. “Till now, we have managed the demand. If the Koodankulam project comes on, our problem will be solved. We hope it will be ready by March 2009,” he said.

Explaining the initiatives taken by the Board to generate more power during the 11th Plan, he said the new projects would generate additional 2200 MW by 2011.

On the improved power situation in the State, Mr. Machendranathan said electricity generated through windmills touched an all-time high of 1800 MW on Thursday.

A milestone in Koodankulam

T.S. SUBRAMANIAN


THE final hurdle to the Koodankulam Atomic Power Project (KAPP) becoming a reality was cleared on November 6 when a general framework agreement was signed in Moscow by V.K. Chaturvedi, Chairman and Managing Director, Nuclear Power Corporation of India Limited (NPC), and Viktor Kozlov, General Director, Atomstroiexport of Russia. Under the agreement, which was signed during Prime Minister A.B. Vajpayee's visit to Moscow, Russia will provide financial and technical assistance to the NPC for constructing two reactors of 1,000 MWe capacity each at Koodankulam, a coastal site in Tamil Nadu's Tirunelveli district. Anil Kakodkar, Chairman, Atomic Energy Commission and Secretary, Department of Atomic Energy, who was present at the signing ceremony, called the agreement a milestone in Indo-Russian nuclear electricity cooperation.

Chaturvedi told Frontline that the two reactors were of the VVER-1000 type. They will use enriched uranium as fuel and light water as coolant and moderator. Russia will supply the enriched uranium for the entire life of the plant, provide the design of the reactors and bring equipment, systems, sub-systems and components. The NPC will build the project. Plants will be built at Koodankulam for reprocessing plutonium from the spent fuel. The two reactors will come under International Atomic Energy Agency safeguards (Frontline, July 17, 1998 and October 27, 2000).

According to Chaturvedi, VVER-1000 reactors are advanced versions of Pressurised Water Reactors, and about 50 reactors of this type are operating in Russia, Ukraine and some East European countries. The Koodankulam reactors will incorporate additional safety systems that will take care of severe accident conditions going beyond the design basis.

Civil works are under way at Koodankulam. About 35 per cent of the residential quarters for the project staff have been built. About 70 per cent of the construction of a desalination plant to produce potable water has been completed. About 40 per cent of the earth excavation work for the turbine plant of the first unit is over. The first pour of concrete will take place on March 31, 2002. The first unit is expected to reach criticality towards the end of 2007 and the second unit a year later. About 10,000 people will work at the peak of the construction activity. Preference will be given to local people in the recruitment for class III and IV jobs.

Chaturvedi claimed that KAPP would produce power at Rs.3.10 paise a unit. "The cost is low because the fuel is enriched uranium. Expensive heavy water is not used. The capital cost is competitive. On completion of the project, it will be Rs.6.7 crores for an MWe." Factors such as the adverse effect of foreign exchange rates had been taken into account, he said.

India will finance 46 per cent of the construction cost, which is estimated at about $3 billion. The balance will be raised on credit from Russia.

The project's history is full of vicissitudes. After the Inter-Governmental Agreement (IGA) was signed on November 20, 1988 by Prime Minister Rajiv Gandhi and Soviet President Mikhail Gorbachev, the project became a non-starter because of the disintegration of the Soviet Union and differences over the rouble-rupee ratio. The project was revived when a supplementary agreement was signed on June 21, 1998 in New Delhi by Russian Minister for Atomic Energy Yevgeny Adamov and Atomic Energy Commission Chairman Dr. R. Chidambaram.

Koodankulam Nuclear Power Plant

Koodankulam Nuclear Power Plant is a nuclear power station currently under construction in Koodankulam in the Tirunelveli district of the southern Indian state of Tamil Nadu. Project investment cost to India was estimated to be US$ 3.5 billion in a 2001 agreement.[1]

[edit] HistoryAn Inter-Governmental Agreement on the project was signed on November 20, 1988 by Prime Minister Rajiv Gandhi and Soviet President Mikhail Gorbachev. The project remained in limbo for 10 years due to political and economic upheaval in Russia after the post-1991 Soviet breakup, and also due to objections of the United States on the grounds that the agreement does not meet the 1992 terms of the Nuclear Suppliers Group (NSG).[2]

There are negotiations over the possible addition of a naval base at the site, both safeguarding the project and as a presence in the southern tip of the country.[3] A small port became operational in Kudankulam on January 14, 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.[4]

In 2008 negotiation on building four additional reactors at the site began. Though the capacity of these reactors has not been declared, it is expected that the capacity of each reactor will be 1000 MW or 1 GW.[5][6] The new reactors would bring the total capacity of the power plant to 9200 MW or 9.2 GW.

[edit] Technical descriptionTwo 1 GW reactors of the VVER-1000 model are being constructed by the Nuclear Power corporation of India Limited (NPCIL) and Atomstroyexport. When completed they will become the largest nuclear power generation complex in India producing a cumulative 2 GW of electric power.[7] Both units are water cooled water moderated power reactors.[8] The first was scheduled to start operation in December 2009 and the second one was scheduled for March 2010. Currently, the official projections put unit 1 into operation in June 2011, and unit 2 in March 2012.[9][10][11]

Four more reactors are set to be added to this plant under a memorandum of intent signed in 2008.[12] A firm agreement on setting up two more reactors, has been postponed pending the ongoing talks on liability issues. Under an inter-government agreement signed in December 2008 Russia is to supply to India four third generation VVER-1200 reactors of 1170 MW.[13] The nuclear project will be commissioned in April 2011.[14]

Koodankulam reactors quite safe

Allaying fears in the minds of the public after the recent quake-tsunami-triggered explosion in a couple of nuclear reactors in Japan, Site Director, Koodankulam Nuclear Power Project (KKNPP) M. Kasinath Balaji has said the state-of-the-art safety measures in the 1,000 MWe capacity pressurised water reactors of KKNPP had made the reactors the safest units.

Speaking to reporters at Koodankulam on Tuesday, Mr. Balaji said the nuclear reactors there had been designed to be safe in all natural eventualities such as tsunami and earthquake. The buildings that house the reactor and its auxiliary equipment, reactor safety systems, safety diesel generators, the control room and other power generating equipment — all are designed to operate safely under seismic activity as “Koodankulam comes in a Very Low Seismic Category Zone 2 as per the seismic classification.”

While designing the Koodankulam reactors, the designers have considered the ground elevation of all the buildings to be starting from 7.50 metre (25 feet) above the Mean Sea Level (MSL) to preclude flooding due to any reason whatsoever, including tsunami. These design features got testified when tsunami struck the coast of Tamil Nadu in 2004. The Koodankulam site has been provided with a shore protection bund to a height of 7.50 metre from the MSL.

Third generation design

The reactors have the third generation safety design features, in terms of the various passive safety features backing up the active safety systems, ensuring that the core is always filled with water-containing boron and the temperature of water is well below the limits.

Twelve huge capacity water accumulators have been kept inside the reactor building to ensure that the reactor is filled with water with boron, in the eventuality of loss of water from the reactor core. In addition, the reactor is cooled by way of natural circulation in the event of loss of power supply to the recirculation pumps by the large capacity system generators which are kept at high elevation compared to the reactor.

Further, the steam generator water is cooled by a passive air cooling system which works on the principle of natural convection needing no external power. This ensures long term cooling of reactor core in the event of no power supply to the coolant pumps.

Each reactor at Koodankulam is provided with four redundant diesel generators of which only one is required to keep the reactor in cool state under shutdown condition. The diesel generators at KKNPP are located at a higher elevation of 9 metres (30 feet) above MSL, isolated from tsunami-like natural calamities.

The cooling water pumps for the diesel generators are also kept in secured buildings, capable of withstanding earthquakes. In the unlikely event of unavailability of all diesel generators, the passive heat removal system mentioned above, which is a unique feature of the KKNPP, will ensure cooling of the steam generator using the natural cooling by air. Thus the reactor core is kept in cool condition, ensuring that the fuel cladding temperature is within the limits.

In the most unlikely event of core melt, for which the probability is extremely low in this type of reactors in view of the above mentioned features, there is a special feature called ‘Core Melt Catcher' to contain the core melt if at all it occurs.

To convert any hydrogen formed in the above unlikely event, passive hydrogen re-combiners are provided in the containment to recombine the hydrogen back to water. This precludes the possibility of accumulation of explosive quantity of hydrogen in the containment.

Thus the events that had taken place in Japan would not happen in the Koodankulam reactors.

To verify the structural integrity of the above mentioned systems, the system circuits were hydro-tested and the result accepted by the Indian and Russian specialists as well as the Indian Atomic Energy Regulatory Board.

Safety drill soon

“Unit 1 of KKNPP is getting prepared for hot run in a couple of days when all the safety systems will be tested for its design capability during operation and power generation will start within three months,” Mr. Balaji said, adding that the safety drill rehearsal involving the local communities will be conducted soon.
