      Question

      Which type of fuel is used in the initial phase of

      operation for India’s Prototype Fast Breeder Reactor (PFBR) at Kalpakkam?
      A Uranium-235 Correct Answer Incorrect Answer
      B Plutonium-239 Correct Answer Incorrect Answer
      C Thorium-232 Correct Answer Incorrect Answer
      D Uranium-Plutonium Mixed Oxide (MOX) fuel Correct Answer Incorrect Answer
      E Enriched Uranium fuel Correct Answer Incorrect Answer

      Solution

      For the initial phase, the Prototype Fast Breeder Reactor (PFBR) will operate using Uranium-Plutonium Mixed Oxide (MOX) fuel. The reactor is a sodium-cooled, pool-type Fast Breeder Reactor (FBR) that produces more fuel than it consumes. The core of the reactor is surrounded by a blanket of Uranium-238, and fast neutrons convert these fertile Uranium-238 into fissile fuel. Once operational, India will be the second country after Russia to run a commercial Fast Breeder Reactor.
