India's nuclear power programme was established under the leadership of Dr. Homi Jehangir Bhabha, governed under the Atomic Energy Act, 1962, through the Department of Atomic Energy (DAE) and executed by the Nuclear Power Corporation of India Limited (NPCIL). To overcome domestic natural uranium scarcity while harnessing extensive coastal monazite thorium reserves, Bhabha formulated a sequential Three-Stage Nuclear Power Programme. Stage 1 utilizes Pressurised Heavy Water Reactors (PHWRs) fueled by natural uranium with heavy water (deuterium oxide) as moderator and coolant, generating plutonium-239 as a byproduct. Stage 2 employs Fast Breeder Reactors (FBRs)—exemplified by the 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam—fueled by plutonium-239 to breed fissile uranium-233 from thorium blankets. Stage 3 envisions Advanced Heavy Water Reactors (AHWRs) powered entirely by self-sustaining thorium-uranium-233 fuel cycles. India's operational nuclear fleet includes historic and advanced sites: Tarapur Atomic Power Station in Maharashtra, commissioned in 1969 as India's first commercial facility; Rawatbhata in Rajasthan; Narora in Uttar Pradesh; Kakrapar in Gujarat; Kaiga in Karnataka; and the high-capacity VVER Kudankulam Nuclear Power Plant in Tamil Nadu.
High-yield conceptual summaries for competitive exams and rapid revision.
The Three-Stage Nuclear Power Programme was formulated by Dr. Homi Bhabha to utilize India's vast domestic thorium reserves.
Stage 1 employs Pressurised Heavy Water Reactors (PHWRs) fueled by natural uranium to produce plutonium-239.
Stage 2 utilizes Fast Breeder Reactors (FBRs) to breed fissile uranium-233 from thorium blankets using plutonium fuel.
Stage 3 deploys advanced reactor systems fueled by thorium-232 and bred uranium-233 to ensure long-term energy self-reliance.
Tarapur (Maharashtra) was India's first nuclear power station (1969), while Kudankulam (Tamil Nadu) hosts high-capacity VVER reactors.
