India's PFBR Achieves Criticality, Advancing Nuclear Programme
India's Prototype Fast Breeder Reactor at Kalpakkam has achieved criticality, marking a significant advancement in the country's nuclear energy strategy. This milestone propels India into the second stage of its three-stage nuclear programme, aiming for energy independence through the utilization of thorium reserves.

The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has attained criticality, a key milestone in India's nuclear programme. This 500-megawatt sodium-cooled reactor, developed by Bharatiya Nabhikiya Vidyut Nigam Limited, signifies India's formal entry into the second stage of its nuclear power strategy, overcoming complex engineering challenges.
The PFBR uses recycled fissile material from spent fuel and is designed to generate more fuel than it consumes. This capability is crucial for establishing a closed nuclear fuel cycle. Once fully operational, India will be the second country to run a commercial fast breeder reactor, enhancing its technological capabilities and contributing to climate goals of expanding nuclear capacity to 100 gigawatts by 2047.
