Q4. Explain the working mechanism of fast breeder reactors. Analyse their role in enhancing fuel efficiency. Evaluate their contribution to India’s nuclear strategy. (15 M)
Difficulty Level: Medium
Reference: IE
Why the question
Recent milestone of PFBR criticality (2026) has renewed focus on India’s nuclear strategy and the role of advanced reactor technologies in ensuring long-term energy security.Key Demand of the question
The question requires explaining the technical working of fast breeder reactors and linking it with the concept of fuel efficiency. It further demands evaluating their strategic significance in India’s three-stage nuclear programme and overall energy policy.Structure of the Answer:
Introduction
Briefly highlight India’s resource constraints and the need for advanced nuclear technologies like FBRs to ensure sustainability and energy security.Body
- Working mechanism: Explain in brief how fast neutrons, MOX fuel, and breeding process enable FBR functioning.
- Fuel efficiency role: Indicate how breeding, reprocessing, and closed fuel cycle enhance utilisation of nuclear material.
- Strategic contribution: Show linkage with three-stage programme, energy security, and technological self-reliance.
Conclusion
Underline that FBRs act as a bridge towards a sustainable and self-reliant nuclear future while supporting India’s clean energy goals.
