India's uranium deposits vs coal dependence for electricity; uranium enrichment level required

S&TEnergy & NuclearAssertion-ReasonMediumStatic

Question

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?

Options

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

Answer
d

Statement-I is incorrect but Statement-II is correct

Explanation

Statement-I is correct; India heavily relies on coal for thermal power generation despite domestic uranium reserves. Statement-II is definitively incorrect; commercial nuclear power reactors typically require low-enriched uranium (LEU), enriched to only about 3-5% U-235. Highly Enriched Uranium (HEU) at 60% or above is weapons-grade material, not standard civilian reactor fuel.

Civilian nuclear energy requires Low-Enriched Uranium (3-5%); enrichment above 20% crosses into Highly Enriched, weapons-applicable territory.

Answer: (c).
