Full Summary

India's first indigenous Fast Breeder Reactor (FBR) at Kalpakkam in Tamil Nadu has successfully attained criticality, a crucial step in the nation's three-stage nuclear power programme aimed at utilizing its abundant thorium reserves. The FBR, with a capacity of 500 megawatts electric (MWe), signifies the initiation of a self-sustaining nuclear fission reaction, essential for future power generation. Prime Minister Narendra Modi hailed this achievement as a 'defining step' that showcases India's scientific and engineering capabilities. The FBR will initially operate using uranium-plutonium mixed oxide (MOX) fuel, with plans to transition to thorium-based fuel in the future. This reactor is part of a broader strategy to increase India's nuclear power capacity to 22,400 MWe by 2032, thereby enhancing energy independence. The development of FBR technology is critical for producing more fuel than consumed, facilitating the transition to thorium utilization in subsequent stages of the nuclear programme. India aims to establish a comprehensive nuclear fuel cycle, making it the second country after Russia to operate a commercial FBR.
