Why in news?

  • Recently, member of NITI Aayog V K Saraswat suggested the government to focus on setting up small modular reactors (SMRs).
  • It was suggested to accelerate nuclear power plant projects, set up under fleet mode production, in order to meet India’s base load requirements at the earliest.
  • Small modular reactors will help in meeting requirements in distributed manner.

About Small Modular Reactors (SMRs):

  • Small modular reactors are advanced nuclear reactors, with the power capacity of 300 MW(e) per unit.
  • This equals to 1/3rd of generating capacity of traditional nuclear power reactors.
  • The nuclear plant is likely to be built in a period of 5 years, under fleet mode.
  • An important aspect of the advanced nuclear reactor is that, it is factory fabricated.
  • It can be operated by any agency. Thus, it would attract larger participation of private sector.

Nuclear Power energy in India:

  • Currently, 22 reactors are operational in India, with a total capacity of 6,780 MW.
    • Out of these, 18 reactors are Pressurised Heavy Water Reactors while 4 are Light Water Reactors.
  • Share of nuclear power in overall electricity generation in India was 3.1% in 2020-21.
  • India has planned to enhance the current capacity of 6,780 MW to 22,480 MW by 2031, in line with the net-zero targets.
