It has produced 69 crore units since inception in October 2013. The first unit at Kudankulam Nuclear Power Plant (KKNPP) has, so far, produced 69 crore units of power ever since production started in October 2013, its Site Director, R.S. Sundar, said here on Thursday. He was here to flag off a rally by students on creating awareness of safe nuclear energy. The first unit with a capacity of 1000 MWe has reached the power production of 680 MWe ever since it was resynchronised with the southern grid on February 8, 2014. “Power production capacity of the first unit will cross 700 MWe in one month,” Mr. Sundar told The Hindu over phone. Incidentally, the first unit at KKNPP became the first single nuclear power unit in the country to produce maximum power, he said. “(Before this) Units III and IV at Tarapur Atomic Power Station (in Maharashtra) had the maximum capacity of power production of 540 MWe,” he said. KKNPP is the first nuclear power plant to have VVER-1000, Russian reactors, with a capacity to generate 1000 MWe power each. The ground work for commissioning of the second unit (also 1000 MWe) was under way and power production is likely to begin by September or October, Mr. Sundar said. A total of six reactors have been planned at the KKNPP in Tirunelveli district.
