IGCAR Celebrates 40 Years of Fast Breeder Test Reactor’s First Criticality – A Significant Milestone in India’s Nuclear Energy Journey

The Indira Gandhi Centre for Atomic Research (IGCAR) celebrated the 40th anniversary of the Fast Breeder Test Reactor's (FBTR) first criticality on October 18, 2025.

FBTR, a 40 MWt / 13.6 MWe sodium-cooled reactor, achieved criticality in 1985 and has been pivotal in advancing India's indigenous fast reactor program, pioneering key technologies and laying the groundwork for future reactors like PFBR.
