The completion of tests permits to launch the reactor start-up process. It will begin with loading nuclear fuel into the VVER-1000 reactor core. According to the information from NPCIL, an Indian nuclear power corporation, the plans for this June are to initiate a controlled chain reaction in the reactor core and ramp up the unit to the so-called minimum controllable capacity level (i.e. a level sufficient to sustain and control the nuclear chain reaction). To reach it means to pass one of the most crucial phases in preparing the reactor for operation.

Kudankulam NPP Unit 1 was also constructed by Russian companies. With a capacity of 1000 MW, it is now India’s most powerful reactor compliant with the latest safety requirements. The unit was connected to the Indian national power grid in 2013.

In the spring of 2014, Russia and India signed a framework agreement to build the third and fourth units at Kudankulam. Construction documents were signed in December of the same year.

A framework agreement is currently drafted for Units 5 and 6 of the station. According to the Indian Department of Atomic Energy, Russia and India are negotiating the construction price.

“As for the price of Units 5 and 6, we are considering a commercial offer and a technical proposal made by the Russian party. The price will be announced after the talks”, says the Department’s statement.

Private local companies are also expected to take part in the project. “We plan that local subcontractors will be involved in the project. Private Indian companies will be awarded contracts for equipment deliveries, services and supplies of components produced locally,” a spokesman for the Department said.
