Nuclear Power Surge: India Overhauls Approval Process to Fast-Track Path to 100 GW Target

Nuclear Power Surge: India Overhauls Approval Process to Fast-Track Path to 100 GW Target​

India's commitment to achieving energy security and meeting its net-zero emissions goal by 2070 has necessitated a drastic procedural change in nuclear power project development. The Centre is reportedly exploring a major overhaul of the site identification process, aiming to drastically shorten one of the most time-consuming phases of nuclear expansion.

The move comes as the nation accelerates efforts to expand its current nuclear capacity from 8.78 GW to 22.38 GW by 2031-32. The long-term ambition under the Nuclear Energy Mission is set at an ambitious target of 100 GW by 2047.

Streamlining Nuclear Site Selection for Private Developers​

To overcome decades of project delays, the government is examining whether replacing the Department of Atomic Energy's (DAE) existing Site Selection Committee mechanism with a simplified, checklist-driven framework is viable. This procedural shift aims to ease engagement between developers and various state agencies during early planning stages.

Under the proposed changes, private developers would be allowed to undertake detailed site studies independently and assume associated risks before formal regulatory scrutiny. However, it is mandatory that every proposed location receives rigorous evaluation and licensing from the Atomic Energy Regulatory Board (AERB) and the DAE prior to construction or operation.

The department has also hinted at issuing a "letter of comfort" for developers. This document would help them initiate discussions with state authorities even while the formal site selection process is underway. Safety norms regarding potential sites, including cooling water availability, favorable terrain, grid connectivity, and seismic risk absence, are expected to remain unchanged.

Strategic Nuclear Roadmap Backed by Technological Milestones​

The drive for accelerated execution follows recent significant milestones in India's nuclear technology. On April 6th, the indigenously developed 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam achieved its first criticality. This event marks India's formal entry into the second stage of its three-stage nuclear power programme.

The PFBR, built by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI), utilizes a uranium-plutonium mixed oxide (MOX) fuel recovered from spent fuel generated by Pressurised Heavy Water Reactors. This technology is designed to produce more fissile material than it consumes. The government stated that once the PFBR becomes fully operational, India will be only the second country after Russia to operate a commercial fast breeder reactor.

Maximising Domestic Resources through Three-Stage Strategy​

India's nuclear strategy is fundamentally built around maximising domestic fuel resources. This three-stage process begins with Pressurised Heavy Water Reactors using natural uranium to generate plutonium. The second stage employs this plutonium in Fast Breeder Reactors to create additional fissile material and eventually breed uranium-233 from thorium.

The final stage envisions reactors powered by uranium-233, enabling long-term energy security using India's abundant thorium reserves. Currently, a new nuclear project takes an estimated 11 to 12 years, with 4 to 6 years spent securing state approvals and regulatory permissions before construction begins. Reducing these delays is therefore viewed as critical to meeting the national expansion goals.

Focus on SMRs and Energy Security Commitment​

Beyond large-scale reactors, the Nuclear Energy Mission includes plans for deploying at least five indigenously designed Small Modular Reactors (SMRs) by 2033. This initiative is supported by a ₹20,000-crore allocation announced in the Union Budget 2025-26.

The Bhabha Atomic Research Centre (BARC) is actively developing several next-generation designs, including the BSMR-200 and SMR-55. Nuclear power currently contributes about 3.1 per cent of India's electricity generation. The government views atomic energy as a vital component in supporting the country's long-term energy security objectives.
