TerraPower, the US-based nuclear reactor developer founded by Bill Gates, has signed an agreement with Centrus Energy Corporation to significantly expand their collaboration aimed at establishing commercial-scale, domestic production capabilities for high-assay, low-enriched uranium (Haleu) to supply TerraPower’s first-of-a-kind Natrium reactor and energy storage system.

Centrus and TerraPower will collaborate to ensure the Generation IV Natrium demonstration reactor has access to Haleu “at the milestones necessary to meet the project’s 2030 operation date”.

The two companies will establish a “cost-competitive and timely source” of enrichment capacity in the US at Centrus’ Haleu production facility in Piketon, Ohio
