The issue figured prominently during Summit talks between Prime Minister Narendra Modi and Russian President Vladimir Putin.
"India has agreed to expeditiously identify a second site for Russian-designed nuclear power units in India," External Affairs Ministry Spokesperson Syed Akbaruddin said.
Both sides also decided to fast-track implementation of agreed cooperation projects for nuclear power plants.
Russia has already built a 1000 MW-capacity reactor as part of Kudankulam Nuclear Power Plant and a second reactor is expected to be commissioned next year.
