Nuclear Power Plants of India

The Nuclear Power is the fifth largest power source in India following thermal, hydroelectric, and renewable sources.

Nuclear Power Corporation of India Limited(NPCIL)under theDepartment of Atomic Energy(DAE)is responsible for the construction, design, operation and maintenance of the nuclear power plants across the country.

India currently operates22 nuclear power reactors ins in 7 states, with a total installed capacity of6780 MegaWatt electric(MWe)contributing 3.11% of total power generation in India.Apart from these, India also has18Pressurized Heavy Water Reactors(PHWRs)and4Light Water Reactors(LWRs).

Nuclear Power Plants of India is an important topic for all competitive exams including IBPS, RRB Insurance, PSC & UPSC exams.

Vikram Sarabhai
The first successful nuclear reaction experiment credited to
Ernest Rutherford (1919).He bombarded nitrogen nuclei with alpha particles which resulted in the emission of protons and the creation of oxygen nuclei
The world's first self-sustaining, controlled nuclear chain reaction was conducted by
Enrico Fermi (code name: Chicago Pile-1, 1942)
The Code name for the world's first nuclear explosion /  first detonation of a nuclear weapon
Trinity (conducted by USA, 1945)
Control Rods
used for controlling the fission reaction in the nuclear reactors, they can be inserted or removed from nuclear reactor core and works by absorbing excess neutrons produced during the reaction
