Nuclear power has long been a cornerstone of India’s energy ambitions, yet its growth has historically been measured in decades rather than quarters. This sluggish pace is rooted in the sector’s complex regulatory landscape, high capital costs, and protracted timelines for plant approvals and construction. Today, however, India is embarking on a strategic recalibration of its nuclear policy, aimed at harnessing private capital to accelerate the deployment of small modular reactors (SMRs). This shift is not merely technical but emblematic of a broader policy evolution designed to integrate nuclear energy more seamlessly into the country’s burgeoning clean energy framework, while bolstering energy security and international standing.
At the heart of this policy pivot is the recognition that SMRs—compact, factory-fabricated nuclear reactors with power outputs typically under 300 megawatts—offer a transformative economic and operational model for nuclear power in India. Unlike traditional large reactors, which require bespoke construction over extended periods, SMRs leverage economies of scale through replication and standardisation. Factory assembly and modular construction promise reductions in upfront capital costs, enhanced quality control, and faster deployment. The Indian government’s recent moves to ease restrictions, as reported by The Indian Express, aim to seed domestic SMR supply chains and facilitate site approvals, thereby condensing the historically lengthy timelines that have encumbered nuclear expansion.
Central to this initiative is the ambition to elevate India’s nuclear capacity to 100 gigawatts by 2047, coinciding with the centenary of Indian independence. Achieving this milestone demands systemic reforms: streamlined clearances, assured fuel availability, and revised liability and insurance frameworks that mitigate investor risks. According to Reuters, faster approvals and a retooled framework for fuel security are critical, as India’s existing nuclear plants have suffered from supply chain vulnerabilities and bureaucratic inertia. The liability reforms are particularly significant in attracting private and foreign investment; by clarifying the responsibilities and financial exposures in the event of accidents, the government hopes to create an environment conducive to private sector involvement.
Implementation remains the defining challenge. The government’s strategy focuses on leveraging existing infrastructure—particularly retired thermal power plant sites and operational nuclear facilities—as a means to sidestep protracted siting disputes. Repurposing these sites can truncate the often contentious process of land acquisition and environmental clearances, which have historically delayed nuclear projects. Moreover, standardising SMR designs not only compresses the learning curve for regulators and operators but also facilitates the eventual export of these reactors. Export-grade certification is a strategic objective, positioning India as a future supplier of SMR technology to emerging markets seeking reliable and clean baseload power.
Crucially, the policy acknowledges that private capital alone cannot shoulder the entire burden of nuclear development. Public investment remains indispensable in areas deemed public goods—waste management infrastructure, strategic fuel stockpiles, and emergency preparedness protocols. These components underpin the sector’s safety and sustainability but are often unattractive to private investors due to their long-term horizon and public good nature. By combining public stewardship in these areas with private innovation and efficiency in manufacturing and operations, the sector can achieve bankability and scale.
The climate implications of this nuclear policy shift are profound. As India’s electricity demand surges—projected to triple by 2047—integrating clean energy sources that provide firm, round-the-clock power is paramount. SMRs offer a uniquely valuable complement to variable renewables like solar and wind by reducing the grid’s reliance on costly battery storage and enhancing transmission efficiency. Every megawatt of clean baseload capacity mitigates greenhouse gas emissions while stabilising the grid, thereby advancing India’s commitments under the Paris Agreement and its net-zero ambitions.

Beyond domestic energy security, the SMR initiative carries significant diplomatic overtones. Developing a homegrown SMR supply chain and securing certified sites empowers India to engage as a supplier in the global nuclear market, particularly in regions where energy infrastructure is nascent and geopolitical alignments are fluid. Exporting modular reactors, along with associated training and operations and maintenance (O&M) services, on sovereign terms enhances India’s strategic influence. As The Indian Express highlights, this approach transforms the private sector from mere assembler to innovator, fostering indigenous intellectual property and technological leadership.
The move to embrace private sector participation in nuclear energy also reflects a broader global trend. Countries like the United States, Canada, and the United Kingdom have similarly pivoted towards SMRs and public-private partnerships to revitalize their nuclear industries. India’s policy recalibration thus situates it within an international milieu increasingly favourable to modular nuclear technologies. According to the International Atomic Energy Agency (IAEA), SMRs are poised to play a key role in the global energy transition, especially for countries seeking scalable, low-carbon, and reliable power solutions (IAEA, 2023).
Nevertheless, challenges abound. Regulatory frameworks must evolve rapidly without compromising safety standards, a delicate balance given the inherent risks of nuclear technology. The public perception of nuclear power in India remains ambivalent, shaped by historical accidents elsewhere and concerns over radioactive waste. Effective communication and transparent governance will be essential to securing societal buy-in. Furthermore, the development of a competitive domestic supply chain requires substantial investment in skills, materials, and quality assurance, areas where India is still building capacity.
In parallel, integrating SMRs into India’s complex energy
grid necessitates careful planning. The modular nature of SMRs allows for
incremental capacity additions, aligning with demand growth and grid stability
requirements. However, grid operators must adapt to managing a diversified
energy mix with varying scales and operating characteristics. Digitalisation
and AI-enabled grid management tools can facilitate this transition, ensuring
optimal dispatch and resilience.
India’s nuclear policy evolution also intersects with its geopolitical imperatives. The country’s strategic autonomy in nuclear technology has long been a priority, especially in light of its non-signatory status to the Nuclear Non-Proliferation Treaty (NPT). Developing a robust domestic SMR ecosystem reduces dependence on foreign suppliers and technology, thereby enhancing national security. Moreover, as global powers intensify competition for influence in Asia, Africa, and Latin America, India’s ability to export nuclear technology and expertise under favourable terms strengthens its diplomatic leverage.
In conclusion, India’s strategic embrace of small modular reactors, underpinned by a recalibrated nuclear policy that actively courts private investment, represents a watershed moment for the country’s energy landscape. By accelerating deployment timelines, fostering domestic manufacturing, and creating conducive regulatory and financial environments, India aims not only to meet its ambitious clean energy targets but also to carve out a leadership role in the global nuclear sector. The success of this endeavour will hinge on meticulous implementation, robust public-private collaboration, and an unwavering commitment to safety and sustainability. If realised, the SMR strategy could transform India’s energy future—delivering clean, reliable power while enhancing economic growth and geopolitical stature.
