India's Prototype Fast Breeder Reactor achieves criticality; calls for nuclear regulatory regime revamp

India's Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has achieved first criticality, a significant milestone, though it is 16 years behind schedule and its cost has more than doubled to ₹8,181 crore. The PFBR is crucial for India's three-stage nuclear power programme, aiming for energy security and self-sufficiency by using spent fuel to produce plutonium and eventually thorium. Nuclear power currently contributes about 3% of India's electricity. The article emphasizes the need for scrupulous performance evaluation, honest admission of mistakes, and a revamp of the nuclear regulatory regime. It highlights that the Atomic Energy Regulatory Board (AERB) and the Department of Atomic Energy (DAE) currently report to the Atomic Energy Commission, creating a conflict of interest where the promoter is also the regulator.

Key Points

  • The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has achieved first criticality, a key step in India's nuclear program.
  • The PFBR is integral to India's three-stage nuclear power programme, designed to utilize abundant thorium resources for energy security.
  • The project has faced significant delays (16 years) and cost overruns (more than double the sanctioned amount).
  • There is a critical need to revamp India's nuclear regulatory regime to ensure independent oversight and address conflicts of interest.
  • Nuclear power currently contributes a small percentage to India's total electricity generation.

Exam Facts
