    Located at Kalpakkam in Tamil Nadu, this will mark the beginning of the second stage of India’s three-stage nuclear power programme.

    About Fast Breeder Reactor

    • Genesis: In 2003, government established Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) to construct and operate Prototype Fast Breeder Reactor (PFBR)
      • Earlier first stage was implemented by Nuclear Power Corporation of India Limited (NPCIL).
    • Functioning: 
      • It uses indigenously produced Uranium-Plutonium Mixed Oxide (MOX) fuel and utilizes liquid sodium as a coolant.
      • Uranium-238 “blanket” surrounding fuel core will undergo nuclear transmutation to produce more fuel, thus earning the name ‘Breeder’.

    Significance of FBR

    • Paves way for third stage: It also marks use of Thorium-232 (a non fissile material), which creates fissile Uranium-233 to be used as fuel in third stage.
    • Technological Advancement: India becomes second country after Russia with a commercial FBR.
    • Reduced Nuclear Waste: Uses spent fuel from Stage-I
    • Utilization of Thorium Reserve: Paves the way for the full utilization of India’s abundant thorium reserves.

    India’s 3 stage Nuclear Power Programme:

    • Dr Homi J Bhabha (Father of India’s nuclear programme) devised a three-stage nuclear power programme in the 1950s to make the most of India's limited uranium reserves and abundant thorium reserves.
    A flowchart titled "India's Three-Stage Nuclear Power Program" outlines the three stages of the nuclear energy cycle using natural uranium and thorium.  Stage 1: Pressurised Heavy Water Reactors (PHWRs)  Uses natural uranium (0.7% U-235 and 99.3% U-238).  U-235 undergoes fission to release energy.  U-238 is converted into plutonium-239 (Pu-239).  Generates 10 GWe of electricity.  Stage 2: Fast Breeder Reactors (FBRs) using plutonium as fuel  Uses a mixed oxide of Pu-239 and U-238.  Pu-239 undergoes fission, generating more Pu-239.  Thorium-232 (Th-232) is introduced once Pu-239 inventory is sufficient.  Produces uranium-233 (U-233).  Generates 300 GWe of electricity.  Stage 3: Advanced Heavy Water Reactor (AHWR)  Fuelled by a mix of thorium and uranium.  Th-232 transmutes into U-233.  U-233 powers the reactor.  Generates a very large amount of electricity.
