The reactor was launched Sunday, after the Indian Atomic Energy Regulatory Board issued an approval on the launch of the Russian-built reactor.
"This is the final stage of physical start-up of the unit. Next, the second unit will be connected to the energy grid of India, which is planned [to be finished] before the end of July 2016," the press service cited Vice President for South Asia Projects Andrei Lebedev.
Russia helped India build two nuclear power blocks near the town of Kudankulam in the southern Tamil Nadu state. They are both equipped with VVER-type reactors producing 2,000 megawatt in total. The first power plant unit was connected to the electricity grid three years ago.
