Power generation at the Kudankulam Nuclear Power Plant in Tamil Nadu has been temporarily suspended for the second time in about a week in order to undertake mandatory tests, official sources said today.

The 1000 MWe first unit was shut down yesterday, a top official of the plant said here.

This is the second exercise undertaken by the authorities after it was synchronised with the southern grid last Friday.

“Yes. It was suspended around 8.03 p.m. yesterday. I cannot tell the time till when it will be like this. But, so far we have generated 300 MWe. We stopped the turbine to undertake mandatory tests”, official sources told PTI.

It may be recalled that last week power production was temporarily halted for tests as mandated by the Atomic Energy Regulatory Board (AERB).

Power at the Kudankulam Nuclear Power Plant would be gradually increased to touch the 1000MWe benchmark by December this year once the unit attains operational stability.

Unit-1 had attained criticality on July 13 this year after much delay following protests against the project by anti-nuclear activists in areas around the complex, citing safety reasons.

Nuclear Power Corporation of India is constructing two 1,000MW units at KNPP jointly with Russia at Kudankulam in Tiruneveli district, about 650 km from here.
