  • India’s first indigenously developed 500-megawatt (MW) Prototype Fast Breeder Reactor (PFBR) at Kalpakkam in Tamil Nadu is expected to achieve criticality in 2019.
  • Criticality is the event of a nuclear reactor reaching self-sustained chain reaction. i.e., no external source of neutrons is required to sustain fission in the reactor core.
  • PFBR has been designed indigenously by Indira Gandhi Centre for Atomic Research (IGCAR).
  • It generates power by burning mixed uranium-plutonium MOX fuel, a mixture of PuO2 and UO2.
  • It is a pool-type reactor with 1,750 tonnes of sodium as coolant.
