In today’s world, control over nuclear energy resources translates into strategic power. In this context, achieving “criticality” in the Prototype Fast Breeder Reactor at Kalpakkam marks a major step toward India’s energy independence.
With this milestone, India joins a select group of nations possessing fast breeder technology. The 500 MW reactor not only generates electricity but also produces fuel, making it uniquely valuable.
This development advances India’s three-stage nuclear program, especially the transition to thorium-based energy. Although India’s installed power capacity exceeds 430 GW, over 60% still comes from coal. Renewable sources like solar and wind remain intermittent and cannot ensure continuous supply.
India holds nearly 25% of the world’s thorium reserves but depends on imports for uranium. The Kalpakkam reactor uses plutonium to breed more fuel, including Uranium-233 from thorium. This achievement opens the path to a thorium-powered future, strengthening long-term energy security.
