📘 Q.1 IAS Prelims 2023 — Economics (Energy & Nuclear Power)

🧷 Authentic Classroom Explanation by IAS Monk


📌 The Question:

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?

(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
(c) Statement-I is correct but Statement-II is incorrect
(d) Statement-I is incorrect but Statement-II is correct

Correct Answer: (c)


🧠 Curiosity Raiser

If India has uranium spread across many States, why does coal still dominate our power grid?
And is highly enriched uranium really needed to light our homes?


📘 Enrichment Notes (Conceptual Clarity)

🔹 Statement I — Correct

  • India does possess uranium deposits across several States such as Andhra Pradesh, Telangana, Jharkhand, Rajasthan, Karnataka, etc.
  • As per the Atomic Minerals Directorate (AMD), India has over 3.8 lakh tonnes of in-situ U₃O₈ reserves.
  • Yet, nearly 70–75% of India’s electricity generation still comes from coal-based thermal power plants.
  • Reasons include:
    • Limited domestic uranium production capacity
    • Strategic prioritisation of nuclear fuel
    • Cost, technology, and regulatory constraints
    • Abundant availability of coal

📌 Hence, Statement I is correct.


🔹 Statement II — Incorrect

  • Uranium enrichment levels:
    • Natural uranium: ~0.7% U-235
    • Low Enriched Uranium (LEU): ~3–5% U-235 → used in civilian nuclear reactors
    • Highly Enriched Uranium (HEU): >20% U-235
    • ~60% enrichment → close to weapons-grade, not required for electricity
  • Civilian nuclear power generation does NOT require 60% enriched uranium.
  • Countries enriching uranium to ~60% (e.g., Iran) raise nuclear proliferation concerns, not power-generation needs.

📌 Hence, Statement II is incorrect.


🧩 Logical Conclusion

  • India’s dependence on coal is not because uranium must be enriched to 60%.
  • Electricity generation in nuclear reactors works with low enriched uranium (3–5%).

🧘‍♂️ IAS Monk Whisper

In energy policy, abundance does not guarantee dominance — technology, strategy, and feasibility decide the mix.
