What This Article Covers

1.India's Prototype Fast Breeder Reactor (PFBR) achieved criticality on April 6, 2026, marking a key step in its three-stage nuclear programme.

2.The PFBR, designed by IGCAR and built by BHAVINI, uses sodium cooling and mixed oxide fuel to breed plutonium-239 from uranium-238.

3.The SHANTI Act opens nuclear power to private sector participation, supporting the 2047 target of 100 GW nuclear capacity.

The Big Picture
Prelims · HighMains · Medium

India has achieved a critical milestone in its three-stage nuclear programme with the Prototype Fast Breeder Reactor (PFBR) reaching criticality. This indigenous 500 MWe reactor is central to India's long-term energy security strategy, aiming to eventually use thorium and reduce uranium dependency. The development aligns with the national target of 100 GW nuclear electricity by 2047.

Parliamentary Panel Recommends MDO Entry in Uranium Mining; India's 3-Stage Nuclear Plan to Thorium

The Parliamentary Committee on Atomic Energy has recommended allowing Mine Developer-cum-Operator (MDO) participation in uranium mining under DAE oversight to meet India's growing fuel demand for indigenous PHWRs. India currently imports uranium from Kazakhstan, Russia, Uzbekistan, and Canada, and aims to expand nuclear capacity from 8.7 GWe to 100 GWe by 2047. The three-stage nuclear program aims to transition from uranium to thorium for long-term energy self-sufficiency.
