Consider the following statements :
1. Statement-I : India, despite having uranium deposits, depends on coal for most of its electricity production.
2. 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: Option C
Explanation
1. Statement-I asserts that India has uranium deposits but relies heavily on coal for electricity production. India does possess uranium reserves (e.g., in Jharkhand, Andhra Pradesh), but these are generally low-grade and insufficient to meet large-scale energy needs. Coal remains the dominant source of electricity generation in India. Therefore, Statement-I is correct.
2. Statement-II claims that uranium enriched to at least 60% is required for electricity production. This is incorrect. Most nuclear power reactors, including those used in India (like Pressurized Heavy Water Reactors - PHWRs using natural uranium, and Light Water Reactors - LWRs), use natural uranium or low-enriched uranium (LEU), typically enriched to 3-5% Uranium-235. Highly enriched uranium (HEU), especially above 20% and certainly at 60%, is primarily used in research reactors, naval propulsion reactors, or nuclear weapons, not standard electricity generation. Therefore, Statement-II is incorrect.
3. Since Statement-I is correct and Statement-II is incorrect, option (C) is the correct choice.
