The second Russian nuclear reactor at Kudankulam has started up after prolonged delays. Construction of the 917 MWe (net) unit started in 2002 and construction was declared complete a year ago. Its twin was grid-connected in October 2013 and entered commercial operation at the end of 2014 but then required major turbine repairs. They are AES-92 plants using VVER-1000 reactors, financed by Russia but largely built by the Nuclear Power Corporation of India Led (NPCIL). The reactors are from Atomstroyexport and the turbines were made by Silmash in St Petersburg.
