India is strategically focusing on Fast Breeder Reactors (FBRs) to significantly improve nuclear fuel utilization.
The majority of India's current nuclear fleet, Pressurised Heavy Water Reactors (PHWRs), are inefficient, utilizing only about 1% of their fuel.
FBRs are designed to produce more fissile material than they consume, which is vital for India's long-term energy security.
This technology is a cornerstone of India's three-stage nuclear power program, aiming to leverage its vast thorium reserves.
A Fast Breeder Reactor is a nuclear reactor that uses fast neutrons to sustain a chain reaction and is designed to produce more fissile material (like Plutonium-239 from Uranium-238) than it consumes. Unlike conventional thermal reactors that use moderators to slow down neutrons, FBRs operate with fast neutrons, allowing for efficient conversion of fertile materials into fissile ones. This 'breeding' capability is crucial for maximizing energy extraction from nuclear fuel and for countries like India with limited uranium but abundant thorium reserves.
Simple Analogy: Imagine a special type of nuclear 'oven' that not only bakes bread (generates electricity) but also creates more flour (fissile fuel) than it uses for baking. This allows for a continuous and expanding supply of fuel for future use.
FBRs are the core technology for the second stage of India's program, designed to utilize plutonium bred in the first stage (PHWRs) to further breed Uranium-233 from thorium for the third stage.
FBRs enable a closed nuclear fuel cycle, significantly enhancing fuel utilization efficiency and reducing nuclear waste by reprocessing spent fuel and breeding new fissile material.
By efficiently utilizing both uranium and eventually thorium, FBRs are critical for India to achieve long-term energy independence and security, reducing reliance on imported fossil fuels.

Consider the following statements: Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity. Which one of the following is correct in respect of the above statements?
Answer: Statement-I is correct but Statement-II is incorrect
In India, why are some nuclear reactors kept under "IAEA Safeguards" while others are not?
Answer: Some use imported uranium and others use domestic supplies

Answer: It can build fusion reactors for power generation
High for UPSC (strategic, technological, and energy policy implications); Medium for SSC/Railway (basic scientific facts and current developments).
Material capable of sustaining a nuclear fission chain reaction (e.g., Uranium-235, Plutonium-239, Uranium-233).
Material that can be converted into fissile material by neutron absorption (e.g., Uranium-238, Thorium-232).
The ratio of new fissile atoms produced to fissile atoms consumed in a reactor; a ratio greater than 1 indicates a breeder reactor.
