Power generation at Kudankulam Nuclear Power plant was stopped on Tuesday due to a leakage in a steam pipe, a senior official said.
"The plant was generating 600 MW till yesterday. It was stopped on Tuesday due to a technical snag. There was a leakage in a steam pipe, which needed to be plugged immediately," KNPP Site director R Sundar said.
Repairs would be carried out immediately after which power generation would resume, he said.
Power generation at the plant had resumed on January 30 after seven months of shutdown for maintenance, but was suspended on February 5 due to steam leak and was again started.
Earlier on June 24, 2015 the first plant at KNPP, an Indo- Russian collaborative venture, was shut down for maintenance after being in commercial operation since December 31, 2014.
Work is underway on the second 1000 MW reactor, which is expected to be commissioned later this year.
