Two fuel-sector milestones are reshaping how the West approaches enrichment above conventional light-water reactor levels. Urenco USA produced its first commercial product cylinder of low-enriched uranium plus (LEU+), described as the first commercial LEU+ production in the Western world. Separately, Westinghouse Electric Company announced an approximately $1 billion investment in a new nuclear fuel manufacturing facility in Richland County, South Carolina.

LEU+ as a HALEU Feedstock

LEU+ occupies the space between standard LEU and HALEU. It can serve as an essential feedstock for producing HALEU and can increase the amount of fuel a dedicated HALEU facility might produce. For would-be HALEU producers, that means existing and new LEU+ capacity can reduce the separative work burden on dedicated HALEU cascades.

HALEU itself is uranium enriched to between 10% and 20% U-235 and requires a dedicated facility and separate NRC authorization for production.

Westinghouse Targets 5-8% Enrichment

The Westinghouse plant will produce low-enriched uranium fuel with higher enrichment levels ranging from five to eight percent U-235 (LEU+), above conventional LWR enrichment. The company said the facility is the first fleet-scale nuclear fuel factory built in the United States in more than 50 years.

The enhanced fuel enables extended operating cycles and power uprates at existing reactors, helping operators meet rising baseload electricity demand. Westinghouse said the South Carolina expansion strengthens domestic supply chains for commercial nuclear power generation and boosts LEU+ fuel production capability in the United States.

The LEU+ build-out matters for HALEU not because it produces HALEU, but because it normalizes enrichment above 5% across the U.S. licensing and fabrication base.

Urenco's Capacity Trajectory

Urenco USA is investing in its New Mexico facility to expand domestic enrichment capacity to more than 7 million separative work units over the next decade. It will begin construction of a new enrichment plant at the facility in 2029, install 2.1 million SWU of new capacity, start initial cascades in 2032 and add more cascades by 2036. The new capacity will also be available to produce LEU+.

Together, the Urenco and Westinghouse moves suggest a staged pathway: LEU+ enrichment capacity first, LEU+ fabrication capability alongside it, and HALEU cascades layered on as advanced reactors approach first fuel load.
