Stage set for Kudankulam units 3, 4

Following the successful commissioning and synchronisation of the first two 1,000 MWe VVER reactors of Kudankulam Nuclear Power Project (KKNPP), pre-project work on the third and the fourth units has gathered momentum with 6 lakh cubic metre of soil excavated since February, preparing the ground for early commencement of construction work.

Weeks after the second 1000 MWe unit at the Kudankulam Nuclear Power Plant attained criticality, the Atomic Energy Regulatory Board (AERB) has given its nod for generating electricity from the reactor, a top KNPP official said.

“The Kudankulam Nuclear Power Plant Unit-2 has achieved a critical milestone. It first attained criticality on July 10 at 20.56 hours. Having completed the mandatory tests, we have got permission from AERB yesterday for going ahead”, KNPP Site Director R S Sundar said.

The second unit that attained criticality on July 10 cleared all mandatory tests and hence the Atomic Energy Regulatory Board gave its go ahead on Sunday for its synchronisation with the grid.

The “First Pour of Concrete”, a major milestone in the construction of Units 3 and 4, would take place before the start of next fiscal.

The unit-I of the KNPP, an Indo-Russian joint venture, started commercial generation from December 31, 2014. Referring to the recent dedication of Unit-I by Prime Minister Narendra Modi and Russian President Vladimir Putin in the presence of chief minister J Jayalalithaa, he said,”It is a very glorious occasion and significant milestone”.
