Prototype Fast Breeder Reactor (PFBR)
India’s Indigenous Prototype Fast Breeder Reactor (PFBR) and its abundant thorium reserves are indeed pivotal to the country’s future energy security.
The PFBR, located at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam, Tamil Nadu, is a key project in India’s nuclear energy program. It represents the second stage of India’s three-stage nuclear power program.
- The PFBR uses a mixed oxide (MOX) fuel, composed of plutonium-239 and uranium-238. It is designed to produce more fuel than it consumes by converting uranium-238 into plutonium-239, which can then be used as fuel.
- Capacity: The PFBR has a design capacity of 500 MWe (megawatts electric), with plans for future breeders of higher capacity.
- Breeding Ratio: The reactor is designed to achieve a breeding ratio greater than one, meaning it produces more fissile material than it consumes. This is crucial for the sustainability of nuclear fuel.
- Safety: Fast Breeder Reactors (FBRs) operate at higher temperatures and require advanced safety mechanisms. The PFBR includes features like passive cooling and a robust containment structure to enhance safety.
Role in Energy Security
- Fuel Utilization: The PFBR can significantly extend the life of uranium resources by converting fertile uranium-238 into fissile plutonium-239, effectively increasing the availability of nuclear fuel.
- Reduced Dependency on Uranium: By breeding plutonium, the PFBR reduces India’s reliance on imported uranium, contributing to energy self-sufficiency.
