Small Modular Reactors

Facts for Prelims (FFP)

Context: The Indian Government is considering offering incentives, similar to a production-linked incentive (PLI) scheme, to encourage the manufacturing of small modular reactors (SMRs) with the goal of increasing nuclear power’s share in India’s energy production.

  • The government aims to attract private investments and scale up SMR production to reduce costs. PLI schemes, introduced in 2020, provide financial incentives based on a share of the sales value and have been implemented in various sectors.


About Small Modular Reactors:

 Small modular reactors (SMRs) are advanced nuclear reactors with a power capacity of up to 300 MW(e) per unit. This is about one-third of the generating capacity of traditional nuclear power reactors. 

 SMRs are smaller than conventional nuclear reactors and can be built in one location, such as a factory, then shipped, commissioned, and operated at a separate site. This offers significant savings in cost and construction time.


SMRs have the following characteristics: 

  1. Can produce a large amount of low-carbon electricity
  2. Designed with modular technology using module factory fabrication
  3. Pursue economies of series production
  4. Have short construction times
  5. Are flexible in design and require a smaller footprint
  6. Have a power capacity of up to 300 MW per unit
