The first 1000 MW reactor at the Kudankulam Nuclear Power Plant (KKNPP) is under the testing phase and is expected to commence operations next month.

Nuclear Power Corporation of India (NPCI) is delivering the project which will use Russian technology, reactor and fuel.

NPCI is currently testing all the operational phases at the plant and has submitted the report to the Atomic Energy Regulatory Board (AERB) for approval.

The unit located in the Tirunelvei district will begin commence commercial operations, once it receives final approval.

The unit was originally supposed to begin commercial operations in December 2007.
