The Kudankulam NPP was the outcome of a 1988 inter-governmental agreement between the Soviet Union and India.
The dissolution of the Soviet Union delayed the project and it was revived after a supplementary agreement in 1998.
Under the agreement, Russia is required to manufacture and deliver important components for the power plant and provide technical support.
Russia has also extended credit support for the project over the years.
As part of India-Russia nuclear cooperation, Rosatom is scheduled to construct 6 units of VVER-1000, light-water reactors at Kudankulam.
The 1st power unit of the Kudankulam NPP in 2013 was brought to the minimum controlled level (MCU).
In October 2013, it was connected to the power grid of India and in June 2014 it was brought up to 100% capacity.
In July 2016, the 2nd Unit was brought to the MCU.
In August 2016, the Unit was connected to the Indian power grid.
In January 2017 it was brought up to 100% capacity.
The general framework agreement with Rosatom on the construction of the 3rd and 4th Units was signed in the spring of 2014.
In 2017, the Engineering Division of ROSATOM and the Indian Atomic Energy Corporation signed an agreement on the construction of the 3rd stage (Power Units 5 and 6) of the Kudankulam NPP.
Power units 3 and 4 are the 2nd stage of Kudankulam NPP constructed under AES-92 design with VVER-1000 (V-412) reactor type.
The technical solutions implemented in Kudankulam design characterize further evolutionary development of NPPs with high power VVER reactors and transition to creation of a new and safe power unit.
New power units of Kudankulam NPP comply with the most up-to-date safety requirements of IAEA.
The developer - the technical customer of the facility - is Nuclear Power Corporation of India.
The general designer and supplier of equipment is Russian ASE.
India and Russia’s agreement on nuclear power envisions building as many as 12 nuclear plants by 2035.
