A seven-member Russian technocrat team reached the Kudankulam Nuclear Power Project (KKNPP) site on Wednesday to inspect the ‘unusual vibrations’ in the generator section of the second reactor that has temporarily hampered the operation of the reactor at its maximum power generation capacity of 1,000 MWe.

About Kudankulam Nuclear Power Project

Kudankulam Nuclear Power Plant (KKNPP) is the largest nuclear power station in India, situated in Koodankulam in the Tirunelveli district of the Tamil Nadu. KKNPP is scheduled to have six VVER-1000 reactors built in collaboration with Atomstroyexport, the Russian state company and Nuclear Power Corporation of India Limited (NPCIL), with an installed capacity of 6,000 MW of electricity.

The reactors are pressurised water reactor of Russian design. When completed, the plant will become the largest nuclear power generation complex in India, producing a cumulative 2 GW of electric power. Both units are water-cooled, water-moderated power reactors.


Nuclear Power Corporation of India Limited (NPCIL) is a Public Sector Enterprise under the administrative control of the Department of Atomic Energy (DAE), Government of India. The Company was registered as a Public Limited Company under the Companies Act, 1956 in September 1987. 

NPCIL is responsible for design, construction, commissioning and operation of nuclear power reactors. The objectives of NPCIL are operating atomic power plants and implementing atomic power projects for generation of electricity in pursuance of the schemes and programmes of the Government of India under the Atomic Energy Act, 1962. NPCIL also has equity participation in BHAVINI, another PSU of Department of Atomic Energy (DAE) which implements Fast Breeder Reactors programme in the country.

Objectives of NPCIL

  • To maximise the power generation and profitability from nuclear power stations.
  • To increase nuclear power generation capacity in the country, consistent with available resources in a safe, economical and rapid manner, in keeping with the growth of energy demand in the country.
  • To continue and strengthen activities relating to nuclear power programme within the organisation and those associated with it.
  • To develop personnel at all levels through an appropriate Human Resources Development (HRD) programme in the organisation with a view to further improve their skills and performance consistent with the high technology.
  • To continue and strengthen the environmental protection measures relating to nuclear power generation.
  • To continue and strengthen the neighborhood welfare programme/CSR activities for achieving inclusive growth of surrounding population.
  • To share appropriate technological skills and expertise at national and international levels.
  • To bring about modernisation and technological innovation in activities.
  • To coordinate and endeavor to keep the sustained association with the other units of DAE.
