Urenco USA starts its fourth new cascade, halfway through a 700,000 SWU expansion

Urenco/Urenco USA Eunice expansion

The fourth new centrifuge cascade at Urenco USA's Eunice plant began producing low-enriched uranium on 30 March 2026, the halfway point of the current expansion. All four came online ahead of schedule and on budget, adding about 350,000 SWU in a year, as the US prepares for the end of Russian imports.

• Fourth cascade producing since 30 March 2026; all four ahead of schedule and on budget.
• About 350,000 SWU installed in the past year, of 700,000 planned for 2025-27.
• Refurbishment of existing capacity starts in 2027.
• The plant has made more than 50 million SWU since 2010 and can meet about a third of US needs.
