Kudankulam NPP's Unit 2 is finally connected to the grid

It is India's 22nd operating reactor.

Unit 2 of the Kudankulam nuclear power plant in India's southern state of Tamil Nadu has been connected to the electricity grid. It becomes India's 22nd operating power reactor.

The Russian-designed VVER-1000 reactor was synchronized with the southern grid at 11.17am yesterday and is now generating 245 MWe, Nuclear Power Corporation of India Ltd (NPCIL) announced.
Output from Kudankulam 2 is being divided between four states: Tamil Nadu, Karnataka, Kerala and Puducherry.

Plant supplier Atomstroyexport said, "Next comes the stage of unit tests for dynamic stability at different levels of the electrical load and then exit at 100% load. After their completion will take place a 72-hour test at rated power, the results of which will be signed by the act of the provisional acceptance of Kudankulam unit 2 by the Indian customer."

Construction of Kudankulam 2 was completed in July 2015, and it was loaded with its first fuel in May 2016. Following the completion of safety tests, NPCIL began the process of approaching criticality on 8 July by diluting neutron-absorbing boric acid in the primary coolant water. A controlled self-sustaining nuclear fission chain reaction - or criticality - was attained on 10 July.

The grid connection of Kudankulam 2 - making it India's 22nd operating power reactor - brings India's installed nuclear generating capacity to 6780 MWe.
