Explanation:

The Nuclear Power Corporation of India Limited (NPCIL) is a government-owned corporation of India based in Mumbai in the state of Maharashtra. It is wholly owned by the Central Government and is responsible for the generation of nuclear power for electricity. NPCIL is administered by the Department of Atomic Energy, Govt. of India (DAE).
NPCIL was created in September 1987 under the Companies Act 1956, "with the objective of undertaking the design, construction, operation and maintenance of the atomic power stations for generation of electricity in pursuance of the schemes and programmes of the Government of India under the provision of the Atomic Energy Act 1962." All nuclear power plants operated by the company are certified for ISO-14001 (Environment Management System).
NPCIL was the sole body responsible for constructing and operating India's commercial nuclear power plants till setting up of BHAVINI ( Bharatiya Nabhikiya Vidyut Nigam ) in October 2003. As of 10 August 2012 the company had 21 nuclear reactors in operation at seven locations, a total installed capacity of 5780 MWe.[4][5] Subsequent to the government's decision to allow private companies to provide nuclear power, the company has experienced problems with private enterprises "poaching" its employees.
