• GS III (Environment)
  • Clean energy transition, low-carbon energy

Practice Question

Q1.Discuss the significance of the Prototype Fast Breeder Reactor (PFBR) in India’s three-stage nuclear programme.(250 Words)

Static Background

• India’s nuclear strategy designed by Dr. Homi J. Bhabha, based on closed fuel cycle and thorium utilisation for long-term energy security.
• India has limited uranium but ~25% global thorium reserves, necessitating three-stage programme for resource optimisation.

Key Dimensions of India’s Nuclear Pathway

• Scientific–Technological Breakthrough: PFBR uses MOX fuel (U-Pu mix) and fast neutrons, enabling breeding of more fissile material than consumed.
• Closed Fuel Cycle Strategy: Spent fuel reprocessing ensures resource efficiency, reduced waste, and long-term sustainability of nuclear programme.
• Three-Stage Programme Structure:
  • Stage-I (PHWRs): Natural uranium → Plutonium production.
  • Stage-II (FBRs): Plutonium fuel → more fissile material generation.
  • Stage-III (Thorium): U-233 from thorium → long-term energy source.
• Bridge to Thorium Economy: PFBR enables conversion of Thorium-232 → Uranium-233, unlocking India’s vast thorium potential.
• Institutional Ecosystem: Led by Department of Atomic Energy (DAE), IGCAR (design), and BHAVINI (execution) ensuring indigenous technological capability.
• Energy Security Dimension: Nuclear reduces import dependence on fossil fuels, ensuring base-load, reliable power supply.
• Climate Change Mitigation: Nuclear is low-carbon energy source, supporting India’s net-zero target (2070) and NDC commitments.
• Current Nuclear Status:
  • Installed capacity: 8.78 GW
  • Generation: 56,681 MU (2024–25)
  • Share: ~3.1% of electricity mix
• Future Expansion Plan: Capacity projected 22.38 GW by 2031–32 (~3x increase) with 700 MW PHWRs and 1000 MW reactors.
• Long-Term Vision: 100 GW nuclear capacity by 2047 under Nuclear Energy Mission (Budget 2025–26).
• SMR Development Push:
  • ₹20,000 crore allocation for Small Modular Reactors (SMRs).
  • Target: 5 operational SMRs by 2033.
• Advanced Reactor Innovation:
  • BSMR-200 (200 MWe)
  • SMR-55 (55 MWe)
  • HTGR (5 MWth) for hydrogen production
• Legal–Regulatory Reform: SHANTI Act, 2025 enables limited private participation, modernising nuclear governance framework.
• International Cooperation: India has civil nuclear agreements with 18 countries, enhancing technology access and global trust.
• Strategic Significance: Strengthens strategic autonomy in critical energy technologies and reduces geopolitical vulnerabilities in energy supply chains.

Challenges and Criticisms

• High capital costs and long gestation periods limit rapid scaling compared to renewables.
• Public concerns over nuclear safety and waste disposal, especially post global nuclear accidents (Fukushima context).
• Limited domestic uranium reserves, making Stage-I partially import-dependent.
• Technological complexity of FBRs and reprocessing, requiring high safety standards and skilled manpower.
• Regulatory and liability issues may constrain private sector participation despite SHANTI Act reforms.

Way Forward
