Small Modular Reactors (SMRs): India plans at least five indigenous SMRs by 2033
Science & Technology · Friday, 14 August 2026
Under a newly launched Nuclear Energy Mission, the Government of India informed the Lok Sabha that it plans to develop and operationalize at least five indigenous Small Modular Reactors (SMRs) by 2033. The initiative aligns with India’s goal to scale nuclear power capacity to 100 GWe by 2047.
Quick highlights
- Government plans at least five indigenous SMRs to be developed and operationalized by 2033 under a Nuclear Energy Mission.
- Long-term nuclear goal stated: 100 GWe total nuclear capacity by 2047.
- IAEA defines SMRs as reactors with output up to 300 MWe per unit.
- India’s nodal developer: BARC under the Department of Atomic Energy (DAE).
- Legislative framework mentioned: SHANTI Act, 2025, facilitating private sector participation in nuclear tech manufacturing and deployment.
- SMRs emphasize modular factory fabrication and enhanced passive safety features.
Context
The Government of India informed the Lok Sabha that, under a newly launched Nuclear Energy Mission, it plans to develop and operationalize at least five indigenous Small Modular Reactors (SMRs) by 2033.
Key Facts
• Definition: As per IAEA, SMRs typically have power output up to 300 MWe per unit. • Global tracking/oversight: IAEA and OECD Nuclear Energy Agency (NEA) track global SMR designs. • India nodal developer: Bhabha Atomic Research Centre (BARC), under Department of Atomic Energy (DAE). • Legislative framework mentioned: SHANTI Act, 2025 (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act) enabling private sector participation. • Technology basics: controlled nuclear fission (e.g., Uranium-235) generates heat; steam drives turbines or provides industrial heat. • Build approach: modular factory fabrication with shipment to site for assembly. • Features listed: compact output footprint (20–300 MWe), lower land and water needs than large reactors; enhanced passive safety relying on natural physical laws.
Significance
The stated plan connects SMRs to low-carbon electricity and industrial heat, potentially reducing construction timelines and land footprint compared to large nuclear stations while supporting long-term nuclear capacity targets.
Challenges / Way Forward
No specific challenges were provided in the scraped text beyond the general aims. Way forward implied in-source includes indigenous development, modular manufacturing, and enabling frameworks for participation under the stated Act.
Exam Angle
GS3 (Science & Tech / Energy): Nuclear energy, reactor types, safety concepts (passive safety), institutional roles (DAE, BARC), clean energy transition.
