India weighs smaller nuclear buffer zones to accelerate 100 GW target

Summary

• Land reform push: India is considering reducing mandatory exclusion zones around future nuclear reactors to improve land efficiency and speed up project approvals.
• 2047 nuclear target: The proposal supports India’s long-term ambition to expand nuclear power capacity from about 8 GW today to 100 GW by 2047.
• SMR opportunity: Smaller land requirements could support the future deployment of Small Modular Reactors (SMRs) near industrial clusters and energy-intensive manufacturing hubs.

NEW DELHI, May 11, 2026 — India is evaluating major reforms to its nuclear land-use framework as policymakers seek to accelerate the country’s long-term clean energy expansion plans.

Officials familiar with discussions at the Department of Atomic Energy (DAE) and the Atomic Energy Regulatory Board (AERB) said regulators are studying revisions to existing exclusion-zone norms around future nuclear projects, particularly for advanced reactor technologies and Small Modular Reactors (SMRs).

Rethinking reactor exclusion zones

Current Indian nuclear safety regulations require exclusion and sterilized zones around reactor facilities where habitation and certain activities are restricted. These rules were originally framed around older reactor generations and conservative safety assumptions.

Under the new proposal being examined, advanced Generation III+ reactors and future SMRs could potentially operate with reduced land-buffer requirements due to enhanced passive safety systems and improved containment technology.

Officials said the move could significantly increase land utilization efficiency at existing nuclear sites while reducing delays linked to land acquisition and rehabilitation.

Supporting India’s 2047 clean energy goals

India currently operates around 8 GW of nuclear power capacity, with additional reactors under construction at sites including Kakrapar, Rajasthan, Kudankulam, and Gorakhpur.

The government has repeatedly stated that nuclear power will play a major role in achieving India’s long-term net-zero and energy security goals. Expanding capacity to 100 GW by 2047 would require a dramatic acceleration in project development over the next two decades.

Industry experts say reducing land requirements could help lower project costs and improve the viability of multi-reactor nuclear parks in densely populated states.

SMRs attract industrial interest

The policy review also reflects growing global interest in SMRs, which are designed to be smaller, modular, and potentially faster to deploy than conventional nuclear plants.

Indian conglomerates including Tata Power and Adani Power have expressed interest in future advanced nuclear technologies as industries search for reliable low-carbon energy sources.

Analysts believe SMRs could eventually support steel, refining, chemical, and data-centre operations that require stable round-the-clock electricity.

Debate over safety and public acceptance

The proposal has sparked debate among environmental groups and nuclear policy experts, with critics arguing that reducing exclusion zones could increase public exposure risks in the event of a severe accident.

Supporters counter that modern reactor designs incorporate multiple passive safety systems and significantly lower accident probabilities compared with older-generation nuclear plants.

India’s nuclear expansion strategy is also expected to depend heavily on regulatory transparency, public consultation, and improvements in project execution timelines.

Why this matters

• Clean energy scale-up: Nuclear power is increasingly viewed as a key source of stable, carbon-free electricity for India’s future energy mix.
• Industrial decarbonisation: SMRs could help reduce dependence on coal-based captive power in heavy industry.
• Land efficiency: Smaller exclusion zones may improve project economics and speed up reactor deployment in land-constrained regions.

FAQs

Q1. What are nuclear exclusion zones?

These are restricted areas surrounding nuclear facilities where residential or commercial development is limited for safety reasons.

Q2. Why is India reviewing these rules?

Officials believe modern reactor technologies may require less land while maintaining high safety standards.

Q3. What is India’s nuclear power target?

India aims to expand nuclear generation capacity to 100 GW by 2047 as part of its long-term clean energy strategy.

Q4. What are SMRs?

Small Modular Reactors are compact nuclear reactors designed for modular manufacturing, lower upfront costs, and flexible deployment.
