Nuclear power currently contributes 3 per cent of India's electricity generation. New Delhi: India took a significant step towards energy independence on 6 April 2026, when the indigenously designed and built Prototype Fast Breeder Reactor (PFBR) at Kalpakkam attained first criticality. This moment marked the start of a sustained and controlled nuclear chain reaction in the 500 MWe reactor, a technology India has pursued for decades. With this achievement, the country formally entered the sec ...Read More >

New Delhi, Apr 7 (PTI) A 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam in Chennai has successfully attained first criticality (the start of controlled fission chain reaction), marking a historic step in providing long-term energy security and advancing indigenous nuclear technology capabilities, officials said on Tuesday. The criticality was achieved after meeting all the stipulations of the Atomic Energy Regulatory Board (AERB), which had issued a clearance after a rigorous review ...Read More >

Mumbai, Apr 7 (PTI) Experts in the nuclear field on Tuesday hailed India's Prototype Fast Breeder Reactor (PFBR) attaining criticality, terming it a crucial step towards achieving energy security, and noted that very few countries have mastered this technology. They also said that the next step should be to make the technology more "robust" and build more Fast Breeder Reactors. India's 500 MW PFBR successfully attained first criticality (start of controlled fission chain reaction) on April 6. ...Read More >
