The Nuclear Power Corporation of India (NPCIL) has confirmed that the Kudankulam Nuclear Power Project (KKNPP) in the Indian state of Tamil Nadu will be commissioned in May 2013.

The project, which was scheduled to be commissioned in April 2013, has missed several deadlines for commissioning since December 2012.

The NPCIL said the commercial operation of the first of the 2x1000MW reactors of the Indo-Russian project is anticipated by May 2013.

In January 2013, the project secured clearance from the Atomic Energy Regulatory Board (AERB) for the second heat-up and full system tests of Unit-1.

The Kudankulam project is part of an inter-governmental agreement (IGA) signed between India and Russia in 1988 to cooperate in the areas of atomic energy.

Both the countries signed a new IGA in December 2008 to construct four additional nuclear power units at Kudankulam.
