DOE Announces Next Steps to Build Domestic Uranium Supply for Advanced Nuclear Reactors

Currently, HALEU is not commercially available from U.S.-based suppliers, and boosting domestic supply could spur the development and deployment of advanced reactors in the United States. 

In total, Inflation Reduction Act will provide up to $500 million for HALEU enrichment contracts selected through this RFP and a separate one, released in November, for services to deconvert the uranium enriched through this RFP into metal, oxide, and other forms to be used as fuel for advanced reactors. 

Nuclear power is America’s largest source of clean energy and provides firm, reliable, and safe power. Advanced nuclear power designs using HALEU fuels represent a critical set of technologies that can help to reach U.S. emissions targets and contribute to America’s recent pledge with 21 other countries to triple nuclear power globally by 2050.

The existing U.S. fleet of reactors runs on uranium fuel that is enriched up to five percent with uranium-235—the main fissile isotope that produces energy during a chain reaction. However, most U.S. advanced reactors require HALEU, which is enriched between 5% to 20%, to achieve smaller and more versatile designs with the highest standards of safety, security, and nonproliferation. HALEU will also allow developers to optimize their systems for longer life cores, increased efficiencies and better fuel utilization. 

DOE’s Office of Nuclear Energy plans to award one or more contracts to produce HALEU from domestic uranium enrichment capabilities. Once enriched, the HALEU material will be stored on site until there is a need to ship it to deconverters.

Under the HALEU enrichment contracts, which have a maximum duration of 10 years, the government assures each contractor a minimum order value of $2 million, to be fulfilled over the term of the contract. Enrichment and storage activities must occur in the continental United States and comply with the National Environmental Policy Act. Proposals are due by 5 p.m. MST on March 8. This RFP incorporated industry feedback received on a draft version issued in June.
