The famous 3 stages of India’s nuclear energy program. (Today we cracked 2nd stage here - BARC calls it 3rd as 2nd was PFBTR (prototype)) Stage 1 : Convert uranium into plutonium.. Natural uranium has very little fissile U-235. In PHWRs, U-235 undergoes fission to produce energy, while the abundant U-238 absorbs neutrons and converts into plutonium-239 (Pu-239). You generate power and create fissile material for the next stage. Examples: Rajasthan Atomic Power Station, Kakrapar Atomic Power Station, Narora etc Stage 2 : Breed more fuel using fast neutrons Fast breeder reactors use Pu-239 as fuel. When it fissions, it releases high-energy neutrons that convert surrounding U-238 or thorium into more fissile material (Pu-239 or U-233). Net effect: you create more fuel than you consume (breeding). Examples: Fast Breeder Test Reactor (critical today and Modi ji called it out, Prototype Fast Breeder Reactor - Base tech demonstrator) Stage 3 : Thorium to Uranium-233 cycle Thorium-232 is not fissile, but it absorbs a neutron → becomes Uranium-233, which can sustain a chain reaction. 👉 This enables long-term energy using India’s vast thorium reserves. Example: Advanced Heavy Water Reactor (planned) In one line: Uranium → Plutonium → Thorium → U-233 → Sustainable nuclear fuel cycle
