What This Briefing Covers
The United States is undertaking its most substantial rebuild of domestic nuclear fuel supply chain capacity in decades. Three parallel moves — a private enrichment plant expansion by Urenco, $2.7 billion in Department of Energy task orders to three firms, and an unprecedented sale of weapons-grade plutonium to reactor startups — converge as Russian uranium import waivers approach their January 1, 2028 expiration.
The Data
Urenco USA, currently the only commercial-scale uranium enricher in the United States, operates 64 cascades at its National Enrichment Facility in Eunice, New Mexico, producing 4.3 million SWU annually — roughly one-third of US demand (Source: POWER Magazine, June 3, 2026). The company is now constructing a new enrichment plant with up to 24 additional cascades, adding 2.1 million SWU of capacity — a nearly 50% increase. Construction begins in 2029, with first cascades producing in 2032 and full capacity online by 2036. A separate 700,000-SWU expansion is already on track for 2027, with four new cascades having come online ahead of schedule in 2025 and early 2026.
The expansion is 100% privately funded, backed by a record orderbook of €21.3 billion extending into the 2040s (as of December 31, 2025). Urenco pre-qualified for DOE funding but chose to proceed independently.
Meanwhile, the DOE issued $2.7 billion in task orders over ten years, announced January 5, 2026 (Source: U.S. Department of Energy, January 5, 2026): Orano Federal Services received $900 million to expand U.S. domestic LEU enrichment capacity (Project IKE, a $5 billion plant in Oak Ridge, Tennessee targeting 7.4 million SWU/year with an NRC decision expected by April 2027); American Centrifuge Operating (a Centrus subsidiary) received $900 million for HALEU production in Piketon, Ohio with capacity targeted for 2029; and General Matter received $900 million for HALEU in Paducah, Kentucky (Source: POWER Magazine, June 3, 2026).
On the fuel feedstock side, the Trump administration is in advanced negotiations to sell more than 50 tons of weapons-grade Cold War plutonium to private startups including Oklo — the first time the US government has made weapons-grade plutonium available to commercial entities (Source: Oilprice.com, June 3, 2026, citing The New York Times).
The US completed its first commercial 8.5% enrichment run in December 2025, with NRC authorization for 10% enrichment granted in October 2025 — critical for advanced reactor designs requiring high-assay low-enriched uranium (HALEU) (Source: POWER Magazine, June 3, 2026).
What’s Notable or Overlooked
Urenco’s decision to fund its expansion privately, despite pre-qualifying for DOE support, signals confidence in sustained commercial demand independent of government subsidy. The site in Eunice is already NRC-licensed for up to 10 million SWU, meaning future expansions beyond the current plan face fewer regulatory hurdles. Oklo CEO Jacob DeWitte has identified fuel availability as “one of the biggest choke points in expanding nuclear power right now” (Source: Oilprice.com, June 3, 2026).
The Tension
A Breakthrough Institute analysis published November 6, 2025 projects that if the US nuclear fleet grows to 250–490 GW by 2050, enrichment needs could reach 31.4 million to 96.5 million SWU annually, versus approximately 8.8 million SWU of near-term available domestic capacity (The Breakthrough Institute, November 6, 2025; POWER Magazine). In 2024, Russia supplied 20% of the 15 million SWU purchased by US operators, while US-origin material accounted for only 19% (POWER Magazine). Russian uranium import ban waivers expire on January 1, 2028, creating a hard deadline for supply chain replacement (POWER Magazine). Globally, only five large-scale conversion plants operate, and Russia controls roughly 50% of worldwide uranium conversion capacity (Oilprice.com). Even combining Urenco’s full expansion with DOE-funded projects, the gap between projected long-term demand and committed supply remains measured in tens of millions of SWU (POWER Magazine).
Risks and Counterpoints
The Urenco expansion timeline is long — full capacity does not arrive until 2036, eight years after Russian waivers expire. Orano’s Project IKE awaits an NRC decision not expected before April 2027, and the $5 billion plant carries execution risk. Nonproliferation experts have raised concerns about the plutonium sale to private startups, citing reduced oversight risks (Source: Oilprice.com, June 3, 2026). Demand projections in the 31–96 million SWU range assume significant fleet growth that is far from certain.
