Article Summary
Exam-Focused Notes on India's Nuclear Energy Program
Overview
- Nuclear Energy Strategy: India's nuclear program aims for technological self-reliance and sustainable energy, transitioning from uranium-based to thorium-based fuel cycles.
- Target: Achieve 100 GW of nuclear power capacity by 2047 as part of sustainable development goals.
Constitutional References
- Article 21: Right to life, which can be interpreted to include the right to a clean environment, supporting nuclear energy as a clean energy source.
Nuclear Energy Program Structure
- Three-Stage Nuclear Energy Program:
- Phase 1: Utilizes Pressurized Heavy Water Reactors (PHWRs) with natural uranium.
- Phase 2: Fast Breeder Reactors (FBRs) that use plutonium to generate additional fissile material.
- Phase 3: Thorium-based reactors that utilize uranium-233, derived from thorium.
Current Capacities and Developments
- Installed Capacity: 24 operational nuclear reactors with a total capacity of 8.78 GW.
- Under Construction: 9 reactors with a combined capacity of 7.5 GW.
- Future Projects: Approval for 10 indigenous PHWRs and 2 FBRs in fleet mode.
Policy Initiatives
- Nuclear Energy Mission (2025-26): Aims for capacity expansion and enhancement of domestic manufacturing.
- SHANTI Act, 2025: Policy framework fostering innovation and private sector participation in nuclear energy.
Economic Indicators
- Investment: ₹20,000 crores allocated for research, design, and deployment of indigenous Small Modular Reactors (SMRs) under the 2025-26 budget.
- SMR Development: Targets to operationalize at least five indigenous SMRs by 2033.
Environmental Considerations
- Climate Commitments: Nuclear energy reduces dependence on imported fossil fuels, supporting India's climate goals.
- Waste Management: India follows a closed nuclear fuel cycle with advanced vitrification technology for safe waste management.
International Context
- Global Nuclear Landscape: Similar countries like the USA, France, and Russia utilize low-enriched uranium in light water reactors, while India primarily uses natural uranium in PHWRs.
- IAEA Cooperation: India engages with international bodies for nuclear safety and technology exchange.
Science & Technology Updates
- Innovations: Development of advanced reactor designs, including SMRs and high-temperature gas-cooled reactors (HTGR) for hydrogen production.
- Safety Protocols: Robust safety mechanisms integrated into reactor designs to handle nuclear reactions safely.
Key Terminologies
- Base Load Power: Minimum electric power needed to be supplied continuously to the grid.
- Fission vs. Fusion: Fission involves splitting heavy atoms to release energy, while fusion combines light atoms, currently not commercially viable for electricity production.
- Nuclear Fuel Types: Includes natural uranium, low-enriched uranium (LEU), plutonium-239, and mixed oxide (MOX) fuel.
Conclusion
India's commitment to nuclear energy is integral to its vision of becoming a developed nation by 2047, ensuring long-term energy security, economic growth, and environmental sustainability through advanced nuclear technologies and policies.
