Executive Summary
The Nuclear Energy Mission (NEM) aims to expand India’s nuclear power capacity to 100 GWe by 2047 and operationalize five indigenous Small Modular Reactors (SMRs) by 2033. A key legislative milestone is the SHANTI Act, 2025, which opens the sector to private participation and grants statutory status to the Atomic Energy Regulatory Board (AERB). Progress is currently focused on three indigenous reactor designs with approved sites in Tarapur and Vizag.
Key Points / Main Content

NUCLEAR ENERGY MISSION
प्रव तथ: 23 JUL 2026 3:57PM by PIB Delhi
The Nuclear Energy Mission (NEM) announced in the Union Budget 2025–26 with the objective of
achieving 100 GWe nuclear power generation capacity by 2047 to support the vision of Viksit Bharat and
the goal of net zero carbon emissions by 2070. Further, the mission also aims to develop and
operationalise at least five indigenous Small Modular Reactors (SMRs) by 2033.
In this regard, BARC has undertaken design and development of SMRs namely;
220 MWe Bharat Small Modular Reactor (BSMR-200);
55 MWe Small Modular Reactor (SMR-55); and
High Temperature Gas Cooled Reactor (HTGCR) having power up to 5 MWth, for hydrogen production.
Parliament has enacted the SHANTI Act, 2025, focussed on the Nuclear Energy Mission of the
Government of India, to achieve a target of 100 GW by 2047. This Act opens the nuclear energy sector to
the private participation.
Government has drawn up a roadmap for reaching the 100 GW nuclear power capacity by 2047 as
announced in the Nuclear Energy Mission. As per the roadmap, the present nuclear power capacity of
8.78 GW is expected to reach about 22 GW by 2031-32 on progressive completion of projects presently
at various stages of implementation. Another 32 GW of nuclear power capacity is envisaged to be set up
beyond 2032 by NPCIL, comprising of indigenous Pressurised Heavy Water Reactors (PHWR) and Light
Water Reactors (LWR) by 2047 taking the capacity to about 54 GW. As per the roadmap, the balance of
46 GW is expected to be set up by other Public Sector Enterprises (Central & State), State Governments,
Private sector and Joint Ventures in different business models, comprising of reactors of different
technologies.
(A) The BSMR-200 is an indigenous Pressurized Water Reactor (PWR) based power reactor. The current
status of the BSMR-200 is mentioned below;
a. In-principle approval for engineering and construction of BSMR-200 has been received.
b. Proposal for Administrative & Financial sanction is cleared by Atomic Energy Commission (AEC)
and the approval of Empowered Technology Group (ETG) has been obtained.
c. Atomic Energy Commission has approved Tarapur, Maharashtra as site for BSMR-200.
B. The SMR-55 is based on Pressurised Water Reactor design. The current status of the SMR-55 is
mentioned below;
a. In-principle approval for engineering and construction of SMR-55 has been received.
b. Atomic Energy Commission has approved Tarapur, Maharashtra as site for SMR-55C. HTGCR having power up to 5 MWth is being designed and developed by BARC as nuclear heat
source for suitable thermochemical cycle a suitable thermochemical cycle, such as copper-chlorine
cycle, for hydrogen production. The current status of the HTGCR is mentioned below;
a. In-principle approval for engineering and construction of HTGCR has been received.
b. The proposed site for the reactor is BARC, Vizag. Siting consent has been received.
c. Terms of Reference (ToR) for obtaining environmental clearances has been received from the
Ministry of Environment, Forest and Climate Change (MoEF&CC).
The SHANTI Act-2025 envisages participation of private entities in the field of nuclear energy including
R&D in the field to promote indigenous nuclear technology. Also, BARC is engaging Indian industries
through knowledge sharing and handholding for new technology developments for the SMRs, thus
developing nuclear vendors for self-reliance in the field of nuclear technology encouraging R&D
ecosystem in private sector.
To facilitate participation of private sector in nuclear power generation, the SHANTI Act establishes the
regulatory body (Atomic Energy Regulatory Board) so as to give it a statutory status and to carry out its
functions independently. Under the SHANTI Act, the regulatory body will be able to draft their own
regulations and regulatory documents, carry out regulatory oversight, take enforcement action, and make
recommendations to Central Government. In addition, the SHANTI Act will provide enhanced legislative
and regulatory framework for continued excellence in nuclear safety keeping pace with large scale
expansion of nuclear power program.
India has a robust system of implementation of Nuclear Safety and Security for all existing in Nuclear
Power Plants.
Highest priority is accorded to safety and security in all aspects of nuclear power viz. siting, design,
construction, commissioning, and operation. Nuclear power plants are designed adopting safety principles
of redundancy, diversity and provided with fail-safe design features following an overlapping defence-in-
depth approach. This ensures that there are multiple barriers between the source of radioactivity and the
environment. Nuclear power plants are constructed to highest quality standards and the operations are
performed adopting well laid out procedures by highly qualified, trained and licensed personnel. There is
also a robust internal and independent regulatory mechanism in place and periodic safety reviews are
carried out both by Nuclear Power Corporation of India Ltd. (NPCIL) and the Atomic Energy Regulatory
Board (AERB) to ensure safety of the plant.
The nuclear waste handling, treatment, storage and disposal are carried out as per the well laid down
procedures and guidelines stipulated by the AERB in accordance with the Atomic Energy (Safe Disposal
of Radioactive Wastes) Rules, 1987 and the requirements of AERB Safety Code on 'Management of
Radioactive Waste (AERB/SC/RW)'. The adherence to these is verified through periodic inspection
conducted by AERB. The handling and disposal area is kept under surveillance by the facility
management. The environmental monitoring is carried out by Environmental Survey Laboratories (ESLs)
of BARC.Comprehensive safeguards and well-established procedures are implemented to ensure the safe storage,
handling, and disposal of nuclear waste. Waste management practices are governed by stringent
regulatory standards and are designed to protect operating personnel, the public, and the environment.
Radioactive waste is segregated based on its activity level, treated using appropriate techniques such as
chemical decontamination, absorption, ion exchange/membrane separations and volume reduction, and
then conditioned into stable forms suitable for storage. Engineered storage systems with multiple
containment barriers, radiation shielding, and leak detection mechanisms are employed to prevent any
release of radioactivity. Waste handling operations are conducted using remote or shielded systems,
wherever necessary, and under strict radiological surveillance. Regular monitoring, periodic safety
reviews, and adherence to approved waste disposal protocols ensure continued safety throughout the
lifecycle of waste management.
This information was given by Union Minister of State for Prime Minister’s office and Personnel, Public
Grievances and Pensions, Atomic Energy and Space, Dr. Jitendra Singh, in a written reply in the Rajya
Sabha today.
