India to be the second country in the world operating a commercial-level Fast Breeder Reactor

Union Minister Dr Jitendra Singh today said that after Russia, India will be the second country in the world operating a commercial-level fast breeder reactor. Addressing a workshop of MPs and MLAs, on “Small Modular Reactors” the Minister elaborated that India has achieved a significant milestone by developing an indigenously designed 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, which achieved first criticality on April 6, 2026.

Developed by the Indira Gandhi Centre for Atomic Research (IGCAR) and built by BHAVINI, this reactor marks the start of the second stage of India’s three-stage nuclear power program, using uranium-plutonium mixed oxide fuel to produce more fuel than it consumes. With this achievement, India moves toward leveraging its vast thorium reserves in the third stage of its nuclear strategy. Once fully operational, India will be the second country in the world after Russia operating a commercial-level fast breeder reactor, he added.

The session was presided over by Tarun Chugh. Dr Jitendra Singh further explained that the significance of this achievement lies in the fact that with this, India moves toward leveraging its vast thorium reserves in the third stage of its nuclear strategy. Once fully operational, India will be the second country in the world after Russia operating a commercial-level fast breeder reactor.(UPDATED ON 27TH APRIL 2026)
