Capacity Announcements Stack Up

Western enrichment capacity is expanding on three fronts at once. Urenco is adding 2.5 million SWU across its Eunice, Almelo and Gronau sites. Orano plans to add 2.5 million SWU at its Georges Besse II plant from 2028, and separately estimates that Project IKE in Tennessee will require approximately USD 5 billion and begin production early in the next decade. Centrus is pursuing LEU and HALEU expansion at Piketon, Ohio, and has announced plans to invest more than USD 560 million in a high-rate centrifuge manufacturing facility at Oak Ridge.

The distinction between the two categories of capacity matters. Much of the announced SWU is LEU capacity aimed at replacing Russian material in existing light-water reactors. The HALEU-specific additions — Centrus at Piketon, Orano Federal Services through Project IKE, General Matter and Global Laser Enrichment at Paducah — sit on later timelines and, in several cases, on technologies that have not yet produced commercial quantities.

Order Books Signal Buyer Urgency

Urenco ended 2025 with a record order book of EUR 21.3 billion, approximately 14 percent higher than the previous year, with contracts extending into the 2040s.

That backlog reflects a structural shift in how utilities procure enrichment. Long-term contracts are expected to account for the largest share of the market and to record the higher CAGR, as utilities secure non-Russian supply and suppliers use contracted revenue to support capital investment. In effect, the financing model for new SWU now runs through utility balance sheets rather than government budgets alone.

The Deadline That Sets the Pace

The Prohibiting Russian Uranium Imports Act barred Russian LEU imports into the United States from August 11, 2024 through the end of 2040, with waivers available only until January 1, 2028. A potential supply gap after waivers expire is a significant market concern.

The arithmetic behind that concern is stark. Global enrichment capacity is concentrated among Rosatom, Urenco, Orano and China National Nuclear Corporation, and DOE estimates Russia controls about 44 percent of global enrichment capacity and accounts for around 35 percent of U.S. nuclear fuel imports. Replacing that share requires SWU that must be licensed, built and commissioned — a process measured in years, not months, which is why the 2028 date functions as the sector's real schedule benchmark.
