Question map
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?
Explanation
The correct answer is Option 3: Statement-I is correct but Statement-II is incorrect.
Statement-I is correct: While India possesses significant uranium deposits (notably in Andhra Pradesh and Jharkhand), the domestic supply is insufficient and often low-grade. Consequently, India relies heavily on thermal power, with coal accounting for over 70% of its total electricity generation to meet the massive base-load demand.
Statement-II is incorrect: For commercial electricity production in nuclear power reactors, uranium generally needs to be enriched only to 3% to 5% (Low Enriched Uranium - LEU). Some reactors, like India’s PHWRs, even use natural uranium (0.7% U-235). Uranium enriched to 60% or more is considered High Enriched Uranium (HEU) and is typically associated with research reactors or naval propulsion; enrichment levels above 90% are required for nuclear weapons.
Thus, since Statement-I identifies a valid economic reality and Statement-II provides an incorrect technical requirement, Option 3 is the only accurate choice.
PROVENANCE & STUDY PATTERN
Full viewThis is a classic 'Cross-Domain' question. Statement I is pure NCERT Geography (Resources), while Statement II is Core Science/Tech (Nuclear Physics). The strategy is simple: Do not silo your preparation. When you study 'Uranium' in Geography, you must understand 'Enrichment' in Science.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Explicitly lists multiple Indian districts and states with uranium occurrences (e.g., Singhbhum, Hazaribagh, Gaya, Saharanpur, Kerala, Udaipur).
- Names important uranium mining centres and notes commercial exploitation by Uranium Corporation of India Limited.
- Gives an official reserve estimate (Department of Atomic Energy).
- Specifically names major uranium mines (Jaduguda, Bhatin, Narwapahar, Turamdih) in Singhbhum East, Jharkhand.
- Provides a quantitative total uranium reserve figure for India.
- States uranium is a key nuclear mineral and occurs in Dharwar rocks and along the Singbhum copper belt.
- Lists additional districts and states with uranium occurrences (Rajasthan, Chhattisgarh, Maharashtra, Himachal Pradesh).
- Reports coal as the major contributor to generation capacity (coal 223 thousand MW versus hydro/RES 45.4 thousand MW), showing coal dominates installed capacity.
- Provides a recent (2018–19) snapshot of the generation mix, directly linking coal to the largest share of generation capability.
- States that about 65% of total electricity produced is thermal in character (produced by coal, petroleum and natural gas), indicating a clear majority is from thermal sources.
- Establishes that thermal generation—of which coal is the principal fuel—forms the bulk of electricity production.
- Identifies coal as the main source of national commercial energy and quantifies its large share (about 67% of commercial energy), supporting coal's dominance in the energy sector.
- Gives production figures and the central role of coal in meeting commercial energy needs, reinforcing coal's primacy for power generation.
States nuclear energy in India is produced from uranium and thorium, indicating multiple fuel types/paths are used for power reactors.
A student could combine this with knowledge of reactor fuel cycles to infer that not all power reactors rely on a single high-enrichment requirement.
Notes thorium is used for breeding nuclear fuel and that India's Kakrapara-1 reactor uses thorium, showing alternative fuel cycles (thorium-based) exist in commercial settings.
One could use this to reason that reactor designs and required enrichment differ, so a uniform 60% U-235 requirement is unlikely.
Gives uranium as a primary atomic mineral and emphasizes its role in electricity generation (1 kg uranium yields large energy), implying uranium is used in practical power reactors.
A student could combine this with basic reactor technology knowledge (natural vs enriched fuel) to explore typical enrichment levels needed for different reactor types.
Lists many Indian nuclear power stations and units (Tarapur, Rawatbhata, Kakrapara, Kaiga, Kudankulam, etc.), implying a variety of reactor types and technologies are deployed commercially.
Knowing there are many reactor sites, a student could check which reactor types (and thus typical fuel enrichments) are used at these specific stations to judge if 60% enrichment is generally required.
Mentions new indigenous nuclear reactors being added (700 MW each) and domestic industry development, suggesting national reactor designs and fuel strategies may vary rather than universally requiring very high enrichment.
A student could infer that indigenous designs may use different fuel enrichment levels and then compare typical commercial reactor design requirements to the 60% figure.
- [THE VERDICT]: Sitter mixed with a Logic Trap. Statement I is standard NCERT; Statement II is an 'Extreme Data' trap detectable via basic Science awareness.
- [THE CONCEPTUAL TRIGGER]: Energy Security & Nuclear Technology. The intersection of Mineral Resources (Geography) and Reactor Fuel Cycles (Science).
- [THE HORIZONTAL EXPANSION]: Memorize the Enrichment Spectrum: Natural Uranium (0.7% U-235), Low Enriched Uranium for Power (3-5%), High Enriched (>20%), Weapons Grade (>90%). Know India's Reactor types: PHWR (uses Natural Uranium) vs LWR (uses Enriched Uranium).
- [THE STRATEGIC METACOGNITION]: When reading about Uranium mines in Majid Husain, ask 'How is this rock turned into electricity?' This leads you to the concept of PHWRs (Pressurized Heavy Water Reactors), which India uses specifically because they run on Natural Uranium, debunking the 'enrichment required' claim.
Identifies the specific Indian districts and states where uranium occurs, including Singhbhum (Jharkhand), Gaya (Bihar), Saharanpur (UP), parts of Rajasthan, Andhra Pradesh and Kerala.

The 'Three-Stage Nuclear Program' Fuel Cycle. Stage 1 (PHWR) uses Natural Uranium (U-238). Stage 2 (FBR) uses Plutonium-239. Stage 3 (AHWR) uses Uranium-233 derived from Thorium. UPSC will likely ask which stage uses Thorium or what fuel the Fast Breeder Reactor uses next.
The 'Bomb Factory' Logic. If commercial electricity required 60% enrichment (High Enriched Uranium), every power plant would effectively be a weapons-grade facility (Weapons grade is >90%, but 60% is dangerously high). Commercial reactors prioritize safety and cost, using 3-5% (Low Enriched Uranium). 60% is an absurdly high threshold for boiling water.
Connect this to International Relations (GS-2). Why does India push for the Nuclear Suppliers Group (NSG) waiver? Because our domestic Uranium is low-grade and insufficient. We need imported Uranium for our civilian reactors. This resource scarcity drives our Foreign Policy.
