Small Modular Reactors: India’s Plan for Five SMRs by 2033
Why in the news
The Government told the Lok Sabha about its plan for home-grown small reactors as the Nuclear Energy Mission begins.
About SMRs
| Aspect | Detail |
|---|---|
| Nature | Advanced reactor with lower output than a gigawatt-scale plant |
| Developer | BARC, Department of Atomic Energy |
| Law | Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act, 2025 |
| Output | Low-carbon baseload power and industrial heat |
| Benefits | Lower upfront cost, shorter build time, less land |
How they work
- Fission of Uranium-235 and similar nuclei in a controlled chain reaction gives heat.
- Parts are made in factories and assembled on site, avoiding long civil work.
- Heat drives steam turbines or serves high-temperature industry.
Exam angle
- Fuel example: Uranium-235.
- Developer: BARC.
- Targets: five SMRs by 2033; 100 GWe by 2047.
