Chennai: Kudankulam Nuclear Power plant's first unit was today shut down for six to eight weeks after a "minor" problem was detected in its turbine generator which had a run for over 190 days.
An official of the Kudankulam Nuclear Power Project (KNPP), an Indo-Russian joint venture, said the problem was minor and the unit is expected to be back in operation in six to eight weeks.
KNPP Unit 1 turbine generator has operated for 4,701 hours so far and generated 282.5 crore units of power, which was supplied to the Southern grid since October 2013, KNPP Site Director R S Sundar said in a statement.
"The unit has been shut down to inspect the turbine and its associated components before putting it for commercial operation", he said.

Sundar said a "minor" deficiency was found on the turbine during inspections. Some of the components needed replacement and officials are working on it, he later told PTI.

"Maintenance activities are in progress and we wanted some more time to put it back in service. That is why we have taken time", he said.
Sundar said Unit 1 was expected to be back in service in six to eight weeks.

The Nuclear Power Corporation of India(NPCIL) had undertaken construction of two 1,000 MW units at KNPP jointly with Russia at Kudankulam in Tiruneveli district in Tamil Nadu.

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

It was synchronized with the southern power grid on October 22, 2013.
