The Prototype Fast Breeder Reactor at Kalpakkam in Tamil Nadu is a sodium-cooled fast reactor being built by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI).

Fast breeders generate more fissile material than they use and are the second stage of India's three-stage nuclear programme.

महत्त्वाची तथ्ये

Remember these

  • PFBR is at Kalpakkam, Tamil Nadu, and is being built by BHAVINI (Bharatiya Nabhikiya Vidyut Nigam Limited).
  • It is a sodium-cooled fast breeder reactor with a capacity of 500 MWe.
  • A fast breeder produces more fissile material (plutonium-239) than it consumes.
  • It is the second stage of India's three-stage nuclear programme conceived by Homi Bhabha.
  • Stage 1 is PHWRs on natural uranium; stage 3 is thorium-based reactors using uranium-233.

How the exam will ask it

पूर्व

  • Statement: A fast breeder reactor uses liquid sodium as coolant and can generate more fissile material than it uses.
  • Statement: The second stage of India's nuclear programme uses plutonium recovered from stage-1 spent fuel.
  • Statement: BHAVINI, the developer of PFBR, is a public sector company based at Kalpakkam.

मुख्य

GS Paper 3 (Science and Technology / Energy): India's limited uranium but large thorium reserves led to the three-stage programme, and the PFBR is the bridge to the thorium stage. Delays, cost and sodium-handling safety are the challenges; the way forward is timely commissioning, strong safety regulation and building the closed fuel cycle to support clean-energy and energy-security goals.

Quick recall

Answer before you reveal

The Anubhava Mantapa, the 12th-century forum of the Sharanas in present-day Karnataka, is associated with which reformer?

  1. Basavanna
  2. Ramanujacharya
  3. Madhvacharya
  4. Purandara Dasa
उत्तर पहा

उत्तर: A — Correct: Basavanna — The Anubhava Mantapa is associated with Basavanna and the Vachana movement of the Sharanas at Kalyana. • Ramanujacharya — wrong: Ramanujacharya was a Vishishtadvaita philosopher who worked in Melkote, not the founder of this forum. • Madhvacharya — wrong: Madhvacharya founded the Dvaita school at Udupi, which is unrelated to this forum. • Purandara Dasa — wrong: Purandara Dasa was a Haridasa composer of the 15th-16th centuries, later than the Sharana forum.
