X-energy Contracts with Centrus to Support Advanced Nuclear Fuel Fabrication Facility Work

BETHESDA, Md. – Centrus Energy Corp. (NYSE American: LEU), an experienced nuclear fuel technology company, has signed a services contract with X Energy, LLC (X-energy) to support the design of a facility to produce advanced nuclear fuel. The contract builds upon a memorandum of understanding the companies signed in September 2017 to collaborate toward production of fuel for advanced nuclear reactors.

Under the agreement, Centrus will provide X-energy, a pioneering reactor technology and fuel company, with technical expertise and resources to support conceptual design of a facility to produce X-energy’s uranium oxycarbide (UCO) tristructural isotropic (TRISO) fuel forms. This effort includes nuclear criticality safety analysis, manufacturing equipment layout and infrastructure design, and conceptual development of fuel form transport packages. Centrus will also provide facility space to X-energy at Centrus’ Technology and Manufacturing Center in Oak Ridge, Tenn. TRISO fuel forms can meet the requirements for the X-energy Xe-100 high temperature gas cooled reactor, as well as for other advanced nuclear reactor technologies being developed around the world.

The services contract supports the companies’ previously announced joint effort to prepare a deployment plan for X-energy’s TRISO fuel technology; design a cost-effective, highly automated fuel manufacturing process line; and seek funding for a future commercial fuel production facility. With a view towards the potential formation of a joint entity to perform these activities, on March 26, 2018, the companies also entered into an additional Memorandum of Understanding, which defines each party’s relative contributions to be considered in the formation of such an entity.

“Establishment of a U.S. domestic capability to produce qualified, high assay low enriched uranium-based fuel forms has become urgent,” states Harlan Bowers, X-energy President. “Advanced reactor companies must have a reliable fuel source within the next six years to enable first-of-a-kind deployment by the mid-to late-2020s. Through partnership with Centrus, we intend to have our TRISO-X Fuel Fabrication Facility constructed and producing fuel before 2025.”

“Our work with X-energy will build the foundation for deploying an American fuel source for advanced reactors,” said Daniel Poneman, president and CEO of Centrus. “By performing their fuel work in our Oak Ridge Technology and Manufacturing Center, X-energy will be able to leverage our specialized workforce, equipment, and facilities to enhance their competitive advantage in the rapidly evolving advanced reactor market.”

About X-energy

X-energy is an advanced nuclear reactor design and TRISO-based fuel fabrication company. X-energy is developing an innovative nuclear power plant design solution. The Xe-100 is a 200MWt (76MWe) high temperature gas-cooled pebble bed modular reactor that requires less time to construct, uses factory-produced components, cannot melt down, and is “walk-away” safe without operator intervention. In concert with Xe-100 design, X-energy is actively producing TRISO-based fuel forms and will implement pilot scale manufacturing capacities starting in 2018. Reactor and fuel activities are supported by $34M in private investment and a five-year $53M U.S. Department of Energy Advanced Reactor Concept Cooperative Agreement award.
