India is finally thinking big about nuclear energy, but the strategy is anything but conventional. After years of reliance on large, costly reactors, the country is now eyeing a fleet of compact, factory‑built units that promise faster construction, lower upfront costs, and a smaller environmental footprint. An American firm, NuScale Power, is leading the charge, pitching its small modular reactors (SMRs) as the answer to India’s soaring electricity demand and climate commitments. This article explores the policy shift, the technology’s allure, the challenges ahead, and what the next decade could look like for Indian nuclear power.
Reassessing India’s nuclear strategy
For decades, India’s nuclear programme has been dominated by a handful of massive reactors, each costing billions and taking a decade or more to commission. The Ministry of New and Renewable Energy recently released a revised nuclear roadmap that targets an additional 30 GW of capacity by 2035, but the timeline is tight. Growing concerns over carbon emissions, energy security, and the need for rapid grid expansion have forced policymakers to reconsider the traditional model.
The promise of small modular reactors
SMRs are designed to be built in factories, shipped to sites, and assembled in weeks rather than years. Their modular nature allows utilities to scale capacity incrementally, matching demand growth and reducing financial risk. Key advantages highlighted by industry analysts include:
- Reduced capital expenditure: a 300 MW SMR can cost roughly one‑third of a comparable large reactor.
- Enhanced safety: passive cooling systems eliminate the need for active emergency pumps.
- Flexibility: smaller footprints enable deployment in remote or industrial zones.
According to the International Energy Agency, global SMR capacity could reach 200 GW by 2040, and India aims to capture a share of that growth.
U.S. firm NuScale’s aggressive pitch
NuScale Power, a Colorado‑based company, has positioned itself as the front‑runner for India’s SMR rollout. Its flagship 60 MW module can be bundled into a 12‑module plant delivering 720 MW—sizeable enough for a regional grid yet far smaller than traditional reactors. NuScale’s pitch to Indian officials emphasizes:
- “Turn‑key” delivery, with the entire plant fabricated overseas and shipped in containers.
- Financing models that blend private equity, export credit agencies, and Indian government guarantees.
- Technology transfer provisions to develop local manufacturing capabilities.
The company’s recent memorandum of understanding with the Indian Railways envisions SMRs powering high‑speed corridors, showcasing a potential early‑adopter use case.
Regulatory and financing hurdles
Despite the enthusiasm, several obstacles remain. India’s nuclear regulator, the Atomic Energy Regulatory Board (AERB), is still adapting its safety framework to accommodate SMR designs, a process that could add 12‑18 months to project timelines. Moreover, the high‑technology nature of SMRs means that traditional project‑finance structures may not apply, prompting banks to demand robust guarantees.
To bridge the gap, the government has announced a ₹10,000 crore incentive pool for clean‑energy projects, part of which is earmarked for SMR pilots. International bodies such as the World Bank are also exploring green‑bond mechanisms to attract climate‑focused investors.
Roadmap to deployment
Based on the latest policy statements and industry commitments, the projected rollout of SMRs in India could follow this timeline:
| Year | Planned SMR Capacity (MW) | Key Milestones |
|---|---|---|
| 2025 | 120 | First pilot plant licensing completed; site selection in Gujarat. |
| 2027 | 480 | Construction of two 240 MW plants begins; financing agreements signed. |
| 2030 | 1,200 | Commercial operation of first full‑scale SMR cluster; export‑credit facility activated. |
| 2035 | 3,000 | Targeted cumulative SMR capacity to meet 10% of national generation mix. |
These figures are optimistic but align with the government’s ambition to decarbonize the grid while maintaining energy security.
Conclusion
India’s pivot toward small modular reactors reflects a pragmatic blend of urgency and innovation. By embracing factory‑built nuclear units, the country hopes to sidestep the delays and cost overruns that have plagued its larger projects. The partnership with NuScale offers a clear technology pathway, yet success will hinge on regulatory agility, creative financing, and sustained political will. If the projected timeline holds, SMRs could supply a significant slice of India’s power basket by 2035, marking a transformative step in the nation’s clean‑energy journey.
