Urenco USA Hits Halfway Mark in New Mexico Uranium Enrichment Expansion

Urenco USA's $5 billion National Enrichment Facility in Eunice, New Mexico brought its fourth new centrifuge cascade to commercial production on March 30, reaching the halfway mark of a planned 700,000 separative work unit expansion as utilities and fuel fabricators race to close the gap left by the legislated phase-out of Russian enriched uranium.

The April 2 announcement confirmed the milestone for a program running from 2025 through 2027. At its core, those 700,000 SWU represent a roughly 15 percent increase in capacity at the Eunice site and translate directly into additional reactor reload contracts that no longer need to route through Rosatom. The Prohibiting Russian Uranium Imports Act, signed into law in May 2024 and effective August 12 of that year, imposed a hard ban on Russian LEU imports with only limited DOE waiver authority, creating an immediate market gap that domestic enrichers are now under pressure to fill. Urenco's fourth cascade is the most concrete industrial answer to that gap produced so far.

The program's execution record is its own story: Urenco reported that every cascade installed during the current expansion came online ahead of schedule and on budget, a claim that stands out in a capital-intensive sector where large equipment programs routinely slip by months or years. That track record strengthens the company's hand in contract negotiations with utilities that need firm delivery commitments.

Product flexibility is the other competitive lever Eunice now holds. The Nuclear Regulatory Commission previously approved a license amendment permitting enrichment up to 10 percent U-235 at the site, enabling Urenco USA to produce LEU+ material alongside conventional reactor fuel. That authorization positions Eunice to supply the first wave of commercial small modular reactor deployments, which require enrichment levels above the 5 percent ceiling of standard LWR fuel. Commercial LEU+ deliveries to North American utility clients were targeted to begin in 2026, meaning the second half of the current cascade program lands precisely as that new demand is materializing.

The longer-term capacity question hinges on what comes after the current 700,000 SWU tranche. Urenco has outlined a potential further expansion of up to 2.1 million SWU at Eunice, roughly three times the size of the ongoing program, contingent on customer contracts and demand signals. Whether that buildout proceeds will depend on how aggressively utilities and advanced reactor developers commit to long-term domestic supply agreements over the next 12 to 18 months, and on whether federal policy continues tilting the economics against foreign enrichment imports.

Since breaking ground in 2006, more than $5 billion in private capital has gone into the Eunice site. With 350,000 new SWU online and the back half of the expansion still to install, the facility is entering the phase where those decades of investment start directly reshaping the U.S. nuclear fuel market.
