In a significant step for India-US nuclear collaboration, the US Department of Energy (DoE) has granted regulatory approval for Holtec International to transfer small modular reactor (SMR) technology to India. This decision, issued on March 26, 2025, paves the way for deeper nuclear cooperation and bolsters India’s standing in the global SMR market.

Strengthening Nuclear Capabilities
The authorisation enables Holtec to share its unclassified SMR technology with Holtec Asia, Tata Consulting Engineers Ltd, and Larsen & Toubro Ltd. This will facilitate the localization of SMR manufacturing, enhance India’s nuclear expertise, and contribute to the growth of its clean energy infrastructure.
Regulatory Conditions and Oversight
While the approval opens new avenues for nuclear development, it comes with stringent conditions. The technology can only be used for peaceful nuclear purposes under the safeguards of the International Atomic Energy Agency (IAEA). Additionally, Holtec is mandated to submit quarterly reports to the DoE detailing the transfer of technology and support provided.
The authorisation is valid for ten years, with a review scheduled at the five-year mark. This ensures consistent monitoring and compliance with regulatory standards.
A Boost to the 2007 India-US Civil Nuclear Agreement
The approval marks the resolution of a significant regulatory hurdle that had hindered the commercial implementation of the 2007 India-US civil nuclear agreement. By promoting nuclear energy as a clean and sustainable power source, the agreement aligns with India’s ambitious climate goals.
Expanding Opportunities in Nuclear Energy
India’s collaboration with Holtec, a leader in nuclear technology, will accelerate the deployment of SMRs, offering a flexible and scalable solution for clean energy production. This advancement is expected to attract further investment in nuclear infrastructure and strengthen India’s role in the global nuclear energy landscape.
Conclusion
The US approval of Holtec’s SMR technology transfer represents a pivotal moment in India-US nuclear relations. By enhancing domestic capabilities and supporting clean energy goals, this collaboration will drive innovation and reinforce India’s leadership in sustainable energy solutions.
