Quick Revision: The Atomic Energy Mission 2047 aims to scale India’s nuclear power capacity to 100 GW by 2047, leveraging indigenous Small Modular Reactors (SMRs) and advanced reactor technologies like HTGR for hydrogen production.
Why is this in the news?
The Union Budget 2025-26 announced the Atomic Energy Mission as a cornerstone of India’s vision for a ‘Viksit Bharat’ (Developed India) by 2047, aligning with the net-zero carbon emissions target for 2070. This mission aims to expand India’s nuclear power capacity from the current 8.78 GW to 100 GW by 2047, while also fostering indigenous development of Small Modular Reactors (SMRs) and advanced reactor technologies such as the High-Temperature Gas-Cooled Reactor (HTGR) for hydrogen production. The initiative underscores India’s commitment to leveraging nuclear energy for energy security, decarbonisation, and technological self-reliance, with significant implications for both domestic energy policy and international climate commitments.
Background
- India’s nuclear energy programme, initiated in the 1950s under Homi Bhabha, has evolved into a three-stage nuclear power programme based on Pressurised Heavy Water Reactors (PHWRs), Fast Breeder Reactors (FBRs), and Thorium-based reactors.
- As of 2026, India operates 23 nuclear power reactors with a total installed capacity of 8.78 GW, contributing ~3% to the national electricity mix.
- The Atomic Energy Act, 1962, originally restricted private sector participation in nuclear power generation and fuel cycle activities, limiting the sector’s growth.
- India’s Nationally Determined Contributions (NDCs) under the Paris Agreement include a target of 40% non-fossil fuel-based electricity capacity by 2030 and net-zero emissions by 2070.
- The global shift towards Small Modular Reactors (SMRs) and advanced reactor designs has prompted India to accelerate indigenous R&D in these areas to meet future energy demands sustainably.
What is the Atomic Energy Mission 2047?
- A strategic initiative announced in Union Budget 2025-26 to expand India’s nuclear power capacity from 8.78 GW (2026) to 100 GW by 2047, supporting the ‘Viksit Bharat’ vision and net-zero emissions target by 2070.
- The mission includes the indigenous development and deployment of at least five Small Modular Reactors (SMRs) by 2033, with the Bhabha Atomic Research Centre (BARC) leading the design and development of three key SMRs: BSMR-200 (220 MWe), SMR-55 (55 MWe), and HTGR (5 MWe thermal for hydrogen production).
- The phased implementation plan outlines a trajectory where nuclear capacity is expected to reach ~22 GW by 2031-32, and the remaining 46 GW through diverse reactor technologies and public-private partnerships by 2047.
- The BSMR-200 and SMR-55 are indigenous Pressurised Water Reactor (PWR)-based designs, with Tarapur, Maharashtra, approved as the site for their deployment. The HTGR, proposed for Visakhapatnam, is designed for high-temperature applications, including hydrogen production via thermochemical cycles like the Copper-Chlorine cycle.
- The mission emphasises self-reliance (Atmanirbhar Bharat) in nuclear technology, with BARC collaborating with Indian industries to develop a robust nuclear supply chain and indigenous nuclear equipment manufacturers.
- The HTGR’s design and development align with India’s long-term strategy for clean hydrogen production, a critical component of decarbonising hard-to-abate sectors such as industry and transport.
- The mission integrates India’s nuclear energy programme with its climate goals, ensuring energy security while reducing dependence on fossil fuels and contributing to the global effort to limit temperature rise to 1.5°C.

4. Financial and Investment Risks
- High upfront capital costs for nuclear projects (₹8–10 crore per MW) deter private sector participation despite policy incentives.
- Long gestation periods (10–15 years) with uncertain returns, necessitating risk-sharing models (e.g., viability gap funding).
- Need for blended finance mechanisms to de-risk investments in emerging technologies like SMRs and HTGRs.

5. Waste Management and Decommissioning
- Lack of a dedicated national policy for long-term storage and disposal of high-level radioactive waste.
- Decommissioning costs (₹100–200 crore per reactor) and liability frameworks remain ambiguous for future projects.
- Public distrust in government assurances on waste safety requires transparent, third-party audited disposal strategies.
