made for design, development and deployment of indigenous Small Modular Reactors
(SMR);
(b) the details of the Research and Development (R&D) milestones achieved and private
sector partnerships established; and
(c) whether the Department has assessed timeline for first SMR prototype and potential
capacity addition towards 100GW nuclear target by 2047 and if so, the details thereof?
ANSWER
THE MINISTER OF STATE FOR PERSONNEL, PUBLIC GRIEVANCES & PENSIONS
AND PRIME MINISTER’S OFFICE (DR. JITENDRA SINGH)
(a) Under the Nuclear Energy Mission announced in the Union Budget 2025–26, a total
budgetary provision of ₹20,000 crore has been made for the research, design,
development, and deployment of Small Modular Reactors (SMRs). Bhabha Atomic
Research Centre (BARC), a constituent unit of Department of Atomic Energy (DAE)
has undertaken design and development works on SMRs namely,
(i) 220 MWe Bharat Small Modular Reactor (BSMR-200),
(ii) 55 MWe Small Modular Reactor (SMR-55), and
(iii) Up to 5 MWth High temperature gas cooled reactor meant for hydrogen
generation.The lead units of these SMRs will be established at DAE sites for technology demonstration.
The estimated utilisation of the allocated funds by BARC toward setting up SMRs is
mentioned below:
Reactor Cost Outlay (Rs Cr.)
Development and Construction of BSMR-200 5960
Development and Construction of SMR-55 (2 units) 7000
Design and construction of High Temperature Gas Cooled Reactor 320
(HTGCR)
Design, engineering & development works for new reactors 800
Civil and General Infrastructure Development for reactors complex 452
The progress of these SMRs is as follows;
(i) BSMR-200: AEC in-principle approval has been received for the project.
Proposal for administrative & financial sanction is cleared by Atomic Energy
Commission (AEC) for submission of the proposal to the Cabinet Committee.
(ii) SMR-55: In-principle approval has been received for the project.
(iii) HTGCR: In-principle approval has been received for the project. Detailed Project
Report (DPR) has been prepared. Siting consent has been received and Terms of
Reference (ToR) for obtaining environmental clearances has been received from
Ministry of Environment, Forest and Climate Change (MoEF&CC).
(b) The special material called “Advanced Purified Reactor Vessel Alloy (ApuRVA) and
technology for forgings for reactor pressure vessels of BSMR-200 and SMR-55 has been
developed indigenously in collaboration with Indian Industries. The control rod drive
mechanism has also been developed in-house. Necessary technology for deployment of
these reactors is available in the country. Majority of equipment are within
manufacturing capability of Indian Industries with technological handholding by BARC.
Therefore, Indian industries will be engaged in manufacturing of equipment.
(c) Bharat Small Modular Reactor (BSMR) is being jointly designed and developed by
BARC and Nuclear Power Corporation of India Limited (NPCIL), a Govt. of India
enterprise under DAE. Estimated time for construction of BSMR is 60 to 72 months
from receipt of administrative & financial approval.
