Holtec International and EDF have formally submitted a proposal to the United Kingdom government to convert a decommissioned coal-fired power station into a modern nuclear energy center. This initiative involves the installation of up to four SMR-300 units at the former Cottam site in Nottinghamshire. These advanced modular reactors are designed to generate approximately 1.3 gigawatts of clean electricity, illustrating a strategic approach to repurposing fossil fuel sites to provide carbon-free power without the necessity of developing entirely new locations. The project represents a significant step under the nation’s Advanced Nuclear Framework, aiming to combine private investment with proven technology.
Repurposing Existing Infrastructure for Clean Energy
The submission seeks to integrate established reactor technology with existing grid infrastructure to support the country’s expanding energy ambitions. By utilizing the site’s current connections, the Cottam nuclear project aims to minimize the requirement for new transmission infrastructure while delivering reliable power. EDF will provide its extensive operational experience within the British energy sector, while Holtec contributes its SMR-300 reactor technology and manufacturing capability. Simone Rossi, EDF UK Chief Executive, stated: “We are delighted to be working with Holtec International on the development of small modular reactors in the UK. The Cottam project supports the UK government’s ambition to expand nuclear capacity and will facilitate significant re-development of a region that has given so much to the UK through its coal heritage.”
Strategic Deployment and Regulatory Progress
The planned development in Nottinghamshire is intended as a second-of-a-kind deployment, following the Pioneer units currently under review by the U.S. Nuclear Regulatory Commission in Michigan. Holtec has indicated that insights gained from the American project will inform the UK program. The SMR-300 design has already successfully concluded the UK’s Generic Design Assessment, a rigorous regulatory process that evaluates the safety, security, and environmental impacts of nuclear reactor designs. This ensures the technology is prepared for the next stages of development as the project seeks to deliver safe and carbon-free power through the utilization of existing grid infrastructure.
Collaborative Joint Venture for Future Planning
To facilitate the next phases of planning and development, Holtec and EDF have signed Heads of Terms to form a joint venture. This partnership builds upon three decades of collaboration between the two organizations and leverages private investment to advance the deployment of modular units. The regulatory process will continue to guide the project as it moves toward formal approval. Dr. Rick Springman, President of Holtec International, noted: “Our long-standing partnership with EDF, combined with the opportunity created by the UK’s Advanced Nuclear Framework, provides a strong foundation for advancing SMR-300 deployment at Cottam. This submission represents an important milestone for the project and for advanced nuclear energy in Great Britain.” The Cottam nuclear project stands as a testament to the potential of combining manufacturing capability with historical energy sites to meet future demands.
