📘 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%).

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