America's HALEU Bottleneck: 93% Foreign Uranium and No Commercial-Scale Supply
U.S. nuclear expansion plans face a fuel supply bottleneck centered on enriched uranium and HALEU, according to a report citing Department of Energy data. HALEU is enriched between 5% and 20% uranium-235, above the 3%-5% range used in the existing U.S. reactor fleet. The gap between the two enrichment levels is central to the fuel bottleneck described in the report.
Foreign suppliers provided 93 percent of the uranium delivered to U.S. reactors, leaving the front end of the nuclear fuel chain exposed even as domestic enrichment work advances, according to a ZeroHedge report. Domestic production of HALEU is not yet at commercial scale, and the fuel is largely imported from Russia, according to the DOE. The United States has not had a commercial-scale HALEU supply chain.
Global Concentration Risks
Only five plants worldwide operate large-scale uranium conversion, and nearly half of global enrichment capacity is controlled by Russia, according to an OilPrice analysis. That concentration leaves Western reactor developers and utilities exposed to geopolitical disruption, especially as Congress moves to restrict Russian uranium imports.
Needham analyst Carter Goman described Centrus as trading 'at a discount' relative to a structural uranium enrichment deficit that looms over the market.
Some utilities are stockpiling fuel and extending contracts to manage uncertainty, according to company statements. The strategy buys time but does not resolve the underlying shortage of Western conversion and enrichment capacity. For advanced reactor developers, the lack of commercial-scale HALEU supply is a timing risk: reactors may be ready before fuel is.
The U.S. is trying to close the gap through new contracts and licensing. A $1.07 billion contract awarded to a consortium led by Centrus Energy is intended to establish a domestic HALEU supply chain at Piketon, Ohio, with operations expected to begin in the 2030s. The Nuclear Regulatory Commission has also accepted for review General Matter's application to build and operate a uranium enrichment facility in Kentucky. Those projects, however, will take years to deliver material.
The bottleneck is not only about uranium ore or conversion. It extends to enrichment capacity, HALEU transport and fuel fabrication. Until those links are built at commercial scale, the U.S. nuclear revival will depend on imported fuel and stockpiles.
