India’s PFBR

  • 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.
