  1. Which of the following statement/s is/are correct about India’s nuclear energy programme?

    Which of the following statement/s is/are correct about India's nuclear energy programme?

    1. AOnly 1 and 2
    2. BOnly 2 and 3
    3. COnly 1 and 3
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: A

    Stage 2 of the three-stage programme runs on plutonium-fuelled Fast Breeder Reactors, and Stage 3 is built around the thorium-based Advanced Heavy Water Reactor, so statements 1 and 2 hold. Statement 3 is wrong because Kaiga is not India's first indigenous PHWR; the first home-built PHWR units came up earlier at Rawatbhata (RAPS) in Rajasthan.

    What is the primary technical objective of the Second Stage of India's Three-Stage Nuclear Power Programme?

    1. ATo utilize natural uranium to produce electricity and Plutonium-239.
    2. BTo use Fast Breeder Reactors (FBRs) to burn Plutonium-239 and breed more fuel from a Thorium blanket.
    3. CTo utilize India's vast Thorium reserves directly in Advanced Heavy Water Reactors (AHWR).
    4. DTo focus exclusively on the enrichment of Uranium-235 for export to the global market.
    Answer and explanation

    Correct answer: B

    The second stage uses Fast Breeder Reactors that burn the Plutonium-239 produced in stage one, while a thorium blanket around the core breeds Uranium-233 for the third stage. Option (a) describes the first stage, and direct thorium use in AHWR is the third stage.
