X-energy and Centrus Energy Corporation yesterday announced the completion of the preliminary design for X-energy’s TRISO-X Fuel Fabrication Facility, plus the signing of a contract for Centrus to continue its work as the project enters its next phase.
For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.
Centrus Energy Corporation has announced that the Nuclear Regulatory Commission approved the company’s license amendment request to produce high-assay low-enriched uranium at its Piketon, Ohio, enrichment facility. The Piketon plant is now the only U.S. facility licensed to enrich uranium up to 20 percent uranium-235, and it is expected to begin demonstrating HALEU production early next year, according to Centrus.
Three companies that are part of a larger collaboration to develop and demonstrate Natrium, the fast reactor design recently introduced by TerraPower and GE Hitachi Nuclear Energy (GEH), were invited to participate in a webinar hosted by ClearPath to talk about Natrium’s design, fuel requirements, and load-following potential.
The September 21 webinar, titled “Natrium: Latin for Sodium, Big for Advanced Nuclear,” was moderated by Rich Powell, executive director of ClearPath, and featured TerraPower’s Chris Levesque and Tara Neider, Centrus Energy’s Dan Poneman, and Duke Energy’s Chris Nolan.
The Nuclear Regulatory Commission has accepted for review Centrus Energy Corporation’s application to produce high-assay low-enriched uranium at its facility in Piketon, Ohio, the company announced on June 23. HALEU-based fuels will be required for most of the advanced reactor designs currently under development and may also be utilized in next-generation fuels for the existing fleet of reactors in the United States and around the world.
High-assay low-enriched uranium (HALEU) is the fuel of choice for many advanced reactor developers, including Advanced Reactor Concepts, which is designing the ARC-100, a sodium-cooled fast reactor. Developers face a potential supply problem, however: The United States has no clear path to build the commercial HALEU production facilities that would be needed to fuel a fleet of advanced reactors. A letter of intent signed by ARC and Centrus Energy, announced on April 28, calls for cooperation on the deployment of a commercial supply of HALEU and could lead to a HALEU purchase agreement for ARC-100 deployments in the late 2020s.
