The second unit of Kudankulam nuclear plant, which was linked to the southern grid last Monday, will start commercial operation in December, said sources in Nuclear Power Corporation of India (NPCIL).
The unit, a Russia-designed VVER-1000 reactor, is producing about 245 MWe. With this, India's installed nuclear power capacity will go up to 6780 MWe. The unit was completed in July 2015, and first fuel was loaded in May 2016.
Kudankulam first unit has been running commercially since December 2014. Two more VVER-1000s are planned to be built at Kudankulam under a 2014 agreement with Russia. Digging work for these have started and Russia's nuclear export agency, Atomstroyexport, expects that the first concrete will be poured in March 2017. Power production should commence by 2022-2023 from these third and fourth units, informed Elena Gulina, press officer of Russian state nuclear agency Rosatom.
Russia wants to built 12 atomic power units, of which four more are likely to be in Kudankulam. The Kudankulam units are India's largest and first pressurised water reactors. The two running reactors were supplied by Russia and built by NPCIL. They have been placed under IAEA safeguards under supervision by Russian scientists. Russia also supplies all the enriched uranium fuel that the plants need.
