Wedoany.com Report-Oct. 14, Sizewell C, a planned nuclear power plant in the United Kingdom, has finalized key agreements to ensure a reliable fuel supply for its operations. The project has signed a six-year uranium enrichment services contract with Urenco and a long-term fuel fabrication deal with Framatome, supporting the facility’s two-unit design in Suffolk, England.
The Urenco contract will provide enriched uranium for the initial six years of Sizewell C’s operations, sourced from their facility in Capenhurst, near Chester in northwest England. This arrangement establishes a dependable fuel supply chain for the plant’s early phase. Urenco’s CEO, Boris Schucht, emphasized the significance of the partnership: “The importance of Sizewell C in the UK’s energy future cannot be underestimated, and Urenco is proud to have been selected as a supplier of choice. This will support the millions in economic contributions we make to the UK every year through the enrichment site we have in Cheshire, one of four such sites we have globally, as well as helping to grow skills in the nuclear industry, create jobs and strengthen supply chains.”
Additionally, Sizewell C has entered a long-term agreement with Framatome for fuel fabrication, covering the initial reactor cores and several subsequent reloads. The enriched uranium will initially be processed at Framatome’s facility in Romans, France, until a new UK-based factory is operational. This domestic facility is expected to create jobs and enhance the UK’s energy security by reducing reliance on imported fuel. Framatome’s Senior Executive Vice President of the Fuel Business Unit, Lionel Gaiffe, stated: “Framatome is proud to extend its partnership with Sizewell C through this fuel supply contract. We remain deeply committed to helping the country meet its net zero targets and contribute to strengthen security of fuel supply through a diverse and resilient supply chain.”
Designed to feature two EPR reactors, Sizewell C is projected to generate 3.2 gigawatts of electricity, sufficient to power approximately six million homes for over 60 years. The plant mirrors the design of Hinkley Point C in Somerset, leveraging insights from that project—the UK’s first new nuclear build in nearly three decades—to streamline construction and reduce costs. A final investment decision for Sizewell C was confirmed in July 2025.
Joint Managing Directors of Sizewell C, Julia Pyke and Nigel Cann, highlighted the contracts’ broader impact: “These two contracts represent a major moment for Sizewell C and for energy security in the UK – this is about delivering the fuel supply for a project that will power 7% of the UK’s energy needs. This is also another big moment for nuclear jobs in the UK. The fuel that will go in our reactors will be low-carbon and predominantly sourced from the UK, produced by skilled British workers.”
The agreements align with Sizewell C’s commitment to localize 70 percent of its construction value within the UK, with fuel fabrication potentially raising this to 90 percent over the project’s lifetime. These steps bolster the UK’s nuclear industry and energy reliability.
