With growing energy needs should India keep on expanding its nuclear energy programme? Discuss the facts and fears associated with nuclear energy.

In short

India should keep expanding nuclear energy as clean baseload power complementing renewables, while answering fears over safety, cost, liability and waste through independent regulation. Nuclear supplied about 3.1% of electricity in 2024-25 against a 100 GW target by 2047.

Model answer

Introduction
Nuclear power supplied only about 3.1% of India's electricity in 2024-25 (PIB, 2025), yet India targets 100 GW by 2047 to meet rising demand within its net-zero 2070 pledge.
Facts That Favour Expanding Nuclear Energy
Nuclear Power Capacity Targets
Nuclear capacity of 8,780 MW today against a 100 GW target for 2047 (Economic Survey 2025-26)
•

Clean baseload

Nuclear runs round the clock with lifecycle emissions of about 12 g CO2 per kWh (IPCC AR5), filling the gap that solar leaves at night.

•

Capability and plan

Indigenous 700 MWe PHWRs, ten approved in fleet mode, and the Rs 20,000 crore SMR mission (Budget 2025-26) back the target.

•

Fuel security

India's vast thorium reserves promise long-term fuel through the three-stage programme.

Fears Associated With Nuclear Energy
•

Safety

Fukushima (2011) fed the Kudankulam protests, though the Supreme Court (2013) allowed the plant with 15 safety directions.

•

Regulatory trust

The CAG (2012) found AERB lacking statutory independence.

•

Cost and liability

Jaitapur and Kovvada stalled as supplier liability under the 2010 Act deterred vendors, while solar fell to Rs 2.15 per unit.

•

Waste and fuel

Long-lived spent fuel, mining health concerns at Jaduguda and reliance on imported uranium remain concerns.

Way Forward
•

Trust and reform

A functionally independent regulator, the SHANTI Act (2025) and Bharat Small Reactors at retiring coal sites can ease these fears.

Conclusion
India should keep expanding nuclear energy as a complement to renewables, since no other clean source offers reliable baseload at scale, provided independent regulation and genuine consent make that growth safe and accepted.
