Nuclear Power Plant in India

  • Under the guidance of Dr Homi Bhabha India developed a three-stage nuclear power programme, aimed at optimum utilisation of India’s nuclear resource profile of modest uranium and abundant thorium.
  • The three stages policy of India comprises of Pressurised Heavy Water Reactors (PHWRs) in the first stage, then the Fast Breeder Reactors (FBRs) in the second stage and the last thorium-based systems in the third stage. The policy is aimed at a closed fuel cycle, where the spent or used nuclear fuel of one stage is reprocessed and utilised to produce fuel for the next stage.
  • There is presently 22 nuclear power plant in India with a total capacity of 6780 MW in operation and one reactor, KAPP-3 (700 MW) has been connected to the grid on January 10, 2021. The nuclear plant wise detail is given in the table.
  • The Government of India has granted administrative approval and financial sanction for the construction of 12 more nuclear power reactors which will comprise of-
    • 10 indigenous Pressurized Heavy Water Reactors (PHWRs) -700 MW – to be set up in fleet mode. 
    • 2 Light Water Reactors (LWRs) to be set up in cooperation with Russian Federation. 
  • The details of new nuclear power projects are given below:

Future of Nuclear Power Plant in India

  • The majority of the nuclear power plant in India are indigenously designed pressurized heavy water reactors (PHWRs), although two Russian-designed WERs are in operation, with two further WERs under construction.
  • As is the case with other countries with PHWRs, India has started the process of refurbishing its reactors to allow for extended operation.
  • India has plans to increase its nuclear generation substantially. 
  • In January 2019 the Department of Atomic Energy (DAE) announced that India plans to build 21 new nuclear power reactors – including 10 PHWRs – with a combined generating capacity of 15,700 MWe by 2031
  • In October 2019 DAE chairman Kamlesh Vyas said that 17 nuclear power reactors are planned in addition to those already under construction.
  • India’s Parliamentary Standing Committee on Science & Technology, Environment, Forests and Climate Change recommended in March 2020 that India should aim to at least double the present proportion of electricity generated by nuclear power plants by 2030. The committee said that, for the time being, India should adopt “home-grown” 700 MWe heavy water reactors for its nuclear expansion programme.

Government of India Atomic Energy Commission

  • The Indian Atomic Energy Commission was first established in August 1948 under the Department of Scientific Research, which itself was created a few months earlier in June 1948.
  • The Department of Atomic Energy (DAE) was established on August 3, 1954 under the direct charge of the Prime Minister through a Presidential Order.
  • Headquarters: Mumbai, Maharashtra.
