New Delhi (ABC Live): India's nuclear energy programme has entered a new phase. On 6 April 2026 at 8:25 PM, the 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, attained first criticality. The Department of Atomic Energy said the Atomic Energy Regulatory Board cleared the plant systems after a safety review. IGCAR designed the reactor, while BHAVINI built and commissioned it. (PIB) This is not a routine plant update. Instead, it marks one of the most important recent even ...Read More >
NEW DELHI, April 7 (Xinhua) -- India's Department of Atomic Energy on Tuesday announced that its most advanced indigenously designed nuclear reactor has reached criticality. Criticality in a nuclear programme is the stage at which a nuclear reactor achieves a self-sustaining fission chain reaction, where neutron production equals or exceeds losses. The reactor is located at Kalpakkam in the southern Indian state of Tamil Nadu and operated by state-run Bharatiya Nabhikiya Vidyut Nigam Ltd. "Wi ...Read More >
Hyderabad: Prime Minister Narendra Modi on Monday announced that indigenously designed and built 500 megawatt Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has attained criticality -- which means that it is producing more nuclear fuel than it is consume. This makes India only the second country to run breeder reactors after Russia. Criticality means the start of controlled fission chain reaction: In the PFBR, it means producing more nuclear fuel and electric power. The PFBR runs on a mix o ...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 >
