Energy security experts urged the United States to rebuild its domestic nuclear fuel supply chain, warning that dependence on foreign enrichment threatens the reliability of reactors powering the grid and new advanced plants under development.
Russia historically supplied a significant share of the world’s enriched uranium, and sanctions linked to geopolitical conflicts have disrupted alternative sourcing. U.S. utilities hold limited strategic reserves, raising concerns about fuel availability for existing reactors.
The Department of Energy has funded projects to expand domestic conversion and enrichment capacity, including facilities in Ohio and Tennessee. TerraPower, Hyundai, and other firms announced advanced reactor partnerships that will require specialized fuel forms.
Analysts said bipartisan legislation supporting fuel production could reduce vulnerability, though new plants require years and billions of dollars to reach commercial scale. Without action, experts warn reactor operators may face supply bottlenecks.
The United States currently imports a large share of enriched uranium after domestic enrichment capacity declined for decades. The Nuclear Regulatory Commission is reviewing license applications for new fuel fabrication plants. Advanced reactors planned by TerraPower and X-energy require high-assay low-enriched uranium that few suppliers produce. Bipartisan Senate bills would authorize federal stockpiling and production incentives.
Utilities including Duke Energy and Southern Company rely on stable fuel deliveries for existing reactor fleets. The Inflation Reduction Act included production tax credits for advanced nuclear projects. Kazakhstan and Canada remain major uranium suppliers as U.S. mines expand slowly.
