Why is this in the news?

The Union Minister of State (Independent Charge) for the Department of Atomic Energy (DAE), Dr. Jitendra Singh, presented in the Lok Sabha a comprehensive roadmap for India’s indigenous nuclear energy ecosystem aimed at achieving self-reliance and global competitiveness. The announcement underscores the government’s strategic focus on Small Modular Reactors (SMRs), thorium utilisation, private sector participation, and advanced reactor technologies to enhance nuclear power capacity to 100 GW by 2047. This initiative is part of the Nuclear Power Mission announced in the Union Budget 2025-26 and aligns with India’s three-stage nuclear programme to ensure long-term energy security through sustainable utilisation of domestic thorium reserves.

Background

• India’s nuclear energy programme is governed by a three-stage strategy formulated by Dr. Homi Bhabha, aimed at leveraging domestic uranium and thorium resources for sustainable energy security.
• The Pressurised Heavy Water Reactor (PHWR) technology, indigenous to India, forms the backbone of the current nuclear power capacity, with units such as Kakrapar and Rawatbhata operational.
• The Atomic Energy Regulatory Board (AERB) ensures safety and regulatory oversight for all nuclear installations in India.
• The Nuclear Power Corporation of India Limited (NPCIL) is the public sector enterprise responsible for the design, construction, and operation of nuclear power plants.
• India’s thorium reserves are among the largest globally, estimated at approximately 360,000 tonnes, primarily in the form of monazite sands along the coasts of Kerala, Tamil Nadu, Odisha, and Andhra Pradesh.

What constitutes India’s strategic roadmap for a self-reliant and globally competitive nuclear energy ecosystem?

• The roadmap is structured around the Nuclear Power Mission 2047, which aims to increase India’s nuclear power capacity from the current ~7.5 GW to 100 GW by 2047, ensuring long-term energy security and reducing dependence on fossil fuels.
• Small Modular Reactors (SMRs) are a key focus, with a target to operationalise at least five indigenous SMRs by 2033. SMRs offer flexibility in deployment, shorter construction timelines, and suitability for remote or industrial applications, including replacement of fossil fuel-based captive power plants.
• The three-stage nuclear programme remains central to India’s strategy: Stage-I utilises natural uranium in PHWRs; Stage-II involves fast breeder reactors (FBRs) to utilise plutonium bred from uranium-238; Stage-III targets thorium utilisation in advanced reactors such as the Advanced Heavy Water Reactor (AHWR).
• Advanced reactor technologies under development include high-temperature gas-cooled reactors (HTGRs) for hydrogen production, and sodium-cooled fast breeder reactors (SFRs) at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, which enhance fuel efficiency and reduce waste.
• Domestic manufacturing capabilities are being strengthened through the development of critical components such as reactor pressure vessels, reactivity control drive mechanisms, and low-alloy steel forgings, reducing import dependence and fostering self-reliance in the nuclear supply chain.
• The Department of Atomic Energy (DAE), through its constituent units like the Bhabha Atomic Research Centre (BARC) and IGCAR, is leading R&D in reactor design, fuel cycle technologies, and advanced materials to support the deployment of next-generation nuclear systems.
• Private sector engagement is being encouraged through knowledge-sharing initiatives, R&D partnerships, and the establishment of domestic nuclear vendors, ensuring a collaborative ecosystem for innovation and deployment.
