HALEU-Thorium fuel unsuitable for Indian nuclear reactors: study
GS3Economy · S&T · Environment · Security· Nuclear & new energy technology· Prelims + Mains·
Why in news
BARC researchers concluded that HALEU-Thorium fuel may be unsuitable for India's three-stage nuclear energy program due to reactor redesign requirements and lower plutonium production.
Background
The study, published in Current Science, indicates that HALEU-Thorium would cause increased wear on refueling machinery. It also notes that the fuel produces less plutonium than natural uranium, creating economic challenges for the second stage of India's nuclear plan.
Facts for Prelims
- S&THALEU-Thorium: A nuclear fuel type being evaluated for India's three-stage nuclear energy program.
- BodyBhabha Atomic Research Centre (BARC): The research body that conducted the study on HALEU-Thorium.
- FactHALEU-Thorium produces less plutonium than natural uranium, impacting the economic viability of the second stage of the nuclear plan.
- PostNTPC Ltd. and Clean Core Thorium Energy: Companies currently evaluating the HALEU-Thorium fuel option.
For Mains
Q. Discuss the technical and economic challenges associated with transitioning to Thorium-based fuel cycles in India's three-stage nuclear power program.
Dimensions to cover in your answer
- Technical bottleneck: Requirement for significant reactor redesign and increased wear on refueling machinery.
- Economic constraint: Reduced plutonium yield from HALEU-Thorium compared to natural uranium affecting stage-two viability.
