India’s first Prototype Fast Breeder Reactor (PFBR) in Kalpakkam, Tamil Nadu, is likely to be commissioned by 2025-26.
This marks the second stage of India’s three-stage nuclear programme, focusing on recycling spent fuel.
Developed by BHAVINI (Bharatiya Nabhikiya Vidyut Nigam Limited), the 500 MWe reactor uses plutonium-based mixed oxide fuel (MOX) and liquid sodium as coolant.
The PFBR can utilize spent fuel from Pressurized Heavy Water Reactors (PHWRs).
The reactor is in advanced stages of integrated commissioning, with core loading commenced in March of last year and permission granted for low-power physics experiments.
PFBRs are vital as spent fuel from these reactors will fuel thorium-based reactors in the third stage of India’s closed fuel cycle.
The government aims for 100 GW of nuclear power, with current capacity at 8.18 GW and plans to reach 22.48 GW by 2031-32.
BHAVINI is expected to contribute 3.80 GW through Fast Breeder Reactors.
Unlike traditional reactors, the PFBR uses fast neutrons and breeds more fuel than it consumes.
The design incorporates advanced safety features and operates at higher temperatures for enhanced efficiency.
