Nuclear Power Corporation of India (NPCIL) plans to connect the second unit of the Kudankulam nuclear power plant (KNPP) in southern Tamil Nadu to the grid by September. The power plant, which has a generation capacity of 1,000 megawatt (Mw) will raise the contribution of nuclear power in the country to 6,780 Mw. The first unit, also of 1,000 Mw, was commissioned recently. The third and fourth units, of 1,000 Mw each, will be commissioned by 2022-23, with total investment of Rs 40,000 crore. The second unit attained first criticality (controlled self-sustaining nuclear fission chain reaction in the reactor for the first time) on July 10. Orders for the third and fourth units have been placed with Atomstroyexport of Russia. They will supply the reactors; other construction will be done by NPCIL. The power from unit-I was currently supplied to Tamil Nadu (562.5 Mw), Karnataka (221 Mw), Kerala (133 Mw), Andhra Pradesh (50 Mw) and Puducherry (33.5 Mw), at Rs 4 a unit. The share of power allocation from unit-II will be the same, except for Telangana replacing Andhra. The reactors would ensure the highest level of safety, in line with current global standards. These are Generation III+ reactors, incorporating a combination of active and passive safety systems.
