X-Energy, Inc. (Nasdaq: XE) and Centrus Energy Corp. (NYSE: LEU) announced a definitive agreement for Centrus to supply enrichment services for Low-Enriched Uranium and High-Assay Low-Enriched Uranium (HALEU) to support X-energy's Xe-100 small modular reactor pipeline, according to a press release issued Aug. 6, 2026.

Under the agreement, HALEU enriched by Centrus at its American Centrifuge Plant in Piketon, Ohio will be delivered to X-energy's fuel subsidiary TRISO-X, LLC for fabrication into coated particle fuel at its facility in Oak Ridge, Tennessee. The agreement is structured in phases, scaling HALEU production capacity over a period of years in alignment with X-energy's commercial project pipeline, which the company states totals 11.5 gigawatts.

X-energy previously secured initial HALEU for its first Xe-100 project with Dow through the U.S. Department of Energy's HALEU Availability Program. The new agreement with Centrus is intended to cover a portion of fuel needs for subsequent projects in X-energy's pipeline, which includes commercial Xe-100 deployments with Dow, Amazon, and Centrica across the United States and United Kingdom.

The agreement combines what the companies describe as the first two U.S. Nuclear Regulatory Commission-licensed HALEU fuel facilities in U.S. history. In February 2026, TRISO-X received a 40-year Special Nuclear Material License from the NRC for its Oak Ridge facility, which the companies state was the first new fuel fabrication facility licensed by the NRC in more than 50 years.

"Through our agreement with Centrus, X-energy has secured enrichment capacity that will support our customers' initial fuel needs through the market's transition to a robust commercial HALEU supply," said X-energy CEO J. Clay Sell.

HALEU used in the Xe-100 is enriched to approximately 15.5% uranium-235, compared with less than 5% for conventional reactor fuel.
