India has consciously proceeded to explore the possibility of tapping nuclear energy for the purpose of
power generation. As result, India has planned three stage nuclear programme.
power generation. As result, India has planned three stage nuclear programme.
- STAGE 1 : Pressurised Heavy Water Reactor (PHWR) Pressurised Heavy Water Reactor using Natural UO2 as fuel matrix to produce electricity while generating plutonium-239 as by-product. Heavy water as moderator and coolant India achieved complete self- reliance in this technology and this stage of the programme is in the industrial domain
- STAGE 2 (FBR): Fast Breeder Reactor is India‘s second stage of nuclear power generation. FBR is a nuclear reactor that uses fast neutron to generate more nuclear fuels than they consume while generating power.
In the second stage, it envisages the use of Pu-239 obtained from the first stage reactor operation. As the fuel core in FBR, a blanket of U-238 surrounding the fuel core will undergo nuclear transmutation to produce fresh Pu239 as more and more Pu-239 is consumed during the operation.
Besides a blanket of Th-232 around the FBR core also undergoes neutron capture reactions leading to the formation of U-233. U-233 is the nuclear reactor fuel for the third stage of India‘s Nuclear Power Programme. FBR is known as fast breeder because it doesn‘t use moderator while liquid sodium is used as coolant. India‘s first Prototype Fast Breeder Reactor is a 500 MWe fast breeder nuclear reactor presently being constructed at the Madras Atomic Power Station in Kalpakkam (Tamil Nadu).
- STAGE 3: (Breeder Reactor). A Stage III reactor or an Advanced nuclear power system involves a self-sustaining series of thorium-232-uranium-233 fuelled reactors. U-233, obtained from second stage will be used as fuel in nuclear reactor.
Besides, U-233 fuelled breeder reactors will have a Th-232 blanket around the U-233 reactor core which will generate more U-233 as the reactor goes operational thus resulting in the production of more and more U-233 fuel from the Th-232 blanket as more of the U-233 in the fuel core is consumed helping to sustain the long term power generation fuel requirement.
Hence all the statements are correct.

With reference to the “fast breeder reactor (FBR), consider the ...
Explanation:
1. Generates more nuclear fuels than it consumes:
- This statement is correct. Fast breeder reactors (FBRs) have the ability to produce more nuclear fuel (such as plutonium-239) than they consume. This is achieved through the process of breeding new fuel from fertile material, such as uranium-238.
2. Does not use moderators:
- This statement is correct. Unlike traditional nuclear reactors that use moderators (such as water or graphite) to slow down neutrons, FBRs use fast neutrons without a moderator. This allows for a more efficient breeding of nuclear fuel.
3. Second stage of India's three-stage nuclear programme:
- This statement is also correct. The fast breeder reactor is indeed the second stage of India's three-stage nuclear programme. The first stage involves the use of pressurized heavy water reactors (PHWRs) to produce electricity and plutonium-239. The second stage, which includes FBRs, aims to use the plutonium-239 produced in the first stage as fuel to generate more power and breed thorium-232 into uranium-233 for the third stage.
Therefore, all three statements given above are correct.
