Companies will develop plan for production of fuel forms based on UCO TRISO

X Energy, LLC and Centrus Energy Corp. have signed a memorandum of understanding to explore collaboration toward production of fuel for advanced nuclear reactors, the two companies announced today. X-energy, a pioneering advanced reactor and fuel company, and Centrus, an experienced nuclear fuel technology company, will work toward the development of a fuel fabrication facility. Based on the uranium oxycarbide (UCO) tristructural isotropic (TRISO) fuel form, this facility would provide fuel to X-energy reactors and advanced nuclear reactor companies around the world.

Dr. Kam Ghaffarian, X-energy chief executive officer stated, “X-energy is focused on both our high temperature gas-cooled reactor development and the fuel needed to power our reactors. The Department of Energy has spent close to $400M in developing and qualifying the UCO TRISO particle in preparation for advanced reactor commercialization. X-energy, in partnership with Centrus and taking advantage of its domestic enrichment experience and engineering know-how, is anxious to evaluate how we can together move UCO TRISO into final fuel form production, benefitting many in the industry.”

“X-energy’s innovative reactor design is a potential game-changer for America’s nuclear industry,” said Daniel Poneman, Centrus Energy president and chief executive officer.  “Our technical and engineering teams are eager to help X-energy develop TRISO fuel for their reactor. We agree that American leadership in the global nuclear market requires that we develop an end-to-end domestic capability, from high-assay low-enriched uranium enrichment through fuel production, for next-generation reactors.”

Under the MOU, the companies will jointly 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.

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.
