Nuclear Power Plants & Atomic Energy in India

India's civilian nuclear energy programme is formulated around Dr. Homi J. Bhabha's visionary three-stage strategy, designed to achieve long-term fuel self-sufficiency by utilizing vast domestic thorium reserves. The first stage utilizes Pressurized Heavy Water Reactors (PHWRs) fuelled by natural uranium; the second stage deploys Fast Breeder Reactors (FBRs) utilizing plutonium-239; and the third stage envisions Advanced Heavy Water Reactors utilizing thorium-232. Operational nuclear power plants such as Tarapur, Kudankulam, Rawatbhata, Kakrapar, and Kalpakkam contribute stable base-load electricity. The Nuclear Power Corporation of India Limited (NPCIL) operates these facilities under rigorous regulatory oversight by the Atomic Energy Regulatory Board (AERB), while institutions like the Bhabha Atomic Research Centre pioneer advanced reactor technologies.
