Framatome Signs First Commercial LEU+ Contract, Paving the Way for HALEU Supply Chains

Breaking the 5% Enrichment Barrier

In a landmark development for the commercial nuclear fuel market, Framatome has signed a contract to deliver the world's first nuclear fuel reload with U-235 enrichment above the traditional 5% standard. Widely believed to be destined for Plant Vogtle, this LEU+ (5-10% enrichment) contract represents a significant shift in the commercial light-water reactor fuel market and sets the stage for higher-enrichment fuels.

Regulatory Approvals and Manufacturing Readiness

The successful execution of this contract was made possible by recent regulatory advancements. In March 2026, the Nuclear Regulatory Commission (NRC) finalized a license amendment raising the enrichment ceiling at Framatome's Richland, Washington facility from 5.0% to 6.5% U-235. This site-wide authorization dismantled long-standing regulatory hurdles, allowing the plant to manufacture fuel for extended operating cycles, increasing them from 18 to 24 months. The project is also financially supported by the US Department of Energy (DOE).

A Strategic Stepping Stone to HALEU

Market analysts view the LEU+ contract as a crucial stepping stone toward the widespread adoption of high-assay low-enriched uranium (HALEU), which requires enrichments of 5-20% for advanced small modular reactors. By moving the existing commercial fleet past the 5% limit, the industry is establishing vital commercial precedents, testing transportation casks, and refining manufacturing protocols.

The LEU+ contract bridges the gap between traditional LEU and HALEU, establishing commercial precedent and manufacturing protocols for the 15-20% enrichments required by next-generation advanced reactors.

Deliveries for this historic reload are scheduled to begin in spring 2028, utilizing Framatome's Advanced Fuel Management (AFM) technology. This incremental approach to enrichment limits is effectively de-risking the supply chain, ensuring that the technical and regulatory pathways are fully paved for the advanced reactors of the future.
