Nuclear power plants generated 56681 Million Units of electricity in the year 202425,  contributing  about  3.1%  of  the  total  electricity  generation  in  the  country.

Nuclear  power  plants  are  in  the  central  sector  and  power  generated  by  them  is allocated to the beneficiary states and union territories in the electricity region by the Ministry of Power.

- (b) & (c) Under  the  Nuclear  Energy  Mission,  announced  in  the  Union  Budget  2025-26, Department  of  Atomic  Energy  (DAE)  has  initiated  design  and  development  of SMRs namely 220 MWe Bharat Small Modular Reactor (BSMR-200), 55 MWe Small  Modular  Reactor  (SMR-55)  and  up  to  5  MWth  High  Temperature  Gas Cooled Reactor (HTGCR) with the aim to enhance the share of nuclear power in India's energy mix and decarbonization of transport and industrial sector to meet the goal of net zero carbon emission by 2070.

It  is  planned  to  deploy  the  lead  unit  of  these  SMRs  at  DAE  site  for  technology demonstration.  The lead units of the BSMR-200 and SMR-55 are proposed to be constructed at the Tarapur Atomic Power Station site in Maharashtra, while a high temperature gas cooled reactor of up to 5MWth is proposed to be constructed at Bhabha Atomic Research Centre, Vizag, Andhra Pradesh.

Estimated time for construction of these SMR is 60 to 72 months from receipt of administrative and financial approval.

- (d) Presently, no SMRs are operational/under construction.
- (e) Under the Nuclear Energy Mission (NEM), Government has allocated Rs.20,000 crore for R&D and deployment of at least five indigenous SMRs by 2033.  Further enactment of SHANTI Act, 2025 enables participation of private entity for R&D in nuclear  science  and  technology.    BSMR-200,  SMR-55,  HTGCR  are  being developed indigenously through Indian Industries.  Other critical equipment and components for SMRs are within the capabilities of Indian Industries and are being developed through handholding in BARC.
