TerraPower and Centrus Energy Corp have signed a memorandum of understanding (MoU) to significantly expand their collaboration aimed at establishing commercial-scale, US production capabilities for high-assay, low-enriched uranium (HALEU) to supply TerraPower's first-of-a-kind Natrium reactor and energy storage system.

US Centrus Energy Corp has completed construction of a demonstration cascade of advanced uranium enrichment centrifuges and major supporting systems in Piketon, Ohio. This is a step towards US first-of-a-kind production of High-Assay, Low-Enriched Uranium (HALEU) planned for the end of 2023, assuming it completes the remaining support systems and obtains final approval from the Nuclear Regulatory Commission (NRC). This will be the first new US technology enrichment plant to begin production in 70 years.

US Terrapower’s advanced Natrium nuclear reactor proposed for southwestern Wyoming is expected to be delayed by at least two years, Jeff Navin, TerraPower’s director of external affairs has told the Caspar Star-Tribune. Following Russia’s special military operation in Ukraine, the supply of high assay low enriched uranium (HALEU) needed to fuel the reactor is now in doubt. “We had a plan. It was a very aggressive timeline; we felt pretty confident that we could meet it. But it was all predicated on having our first coreload of fuel come from Russia,” Navin said.

TerraPower has said it expects operation of the Natrium demonstration reactor to be delayed by at least two years because there will not be sufficient commercial capacity to manufacture high-assay low-enriched uranium fuel in time to meet the proposed 2028 in-service date.

The US Department of Energy (DOE) has established a high-assay low-enriched uranium (HALEU) consortium. The Consortium will help to inform DOE activities to secure a domestic supply of HALEU, which is considered crucial for the development and deployment of advanced reactors in the USA. Membership is free and open to any US entity, association, and government organisation involved in the nuclear fuel cycle. It also may include organisations whose facilities are in ally or partner nations designated by DOE.
