Current State of US HALEU Enrichment
The United States faces significant challenges in rebuilding its domestic nuclear fuel supply chain, particularly in the enrichment and conversion sectors. Currently, the only HALEU enrichment cascade in the country consists of just sixteen centrifuge machines located in Piketon, Ohio. This limited domestic capacity stands in stark contrast to the broader uranium market, where foreign enrichers processed 63% of the uranium feed sent out by American utilities last year.
Conversion Capacity and Market Position
Beyond enrichment, the conversion of uranium into uranium hexafluoride (UF6) is another critical bottleneck. Solstice Advanced Materials operates the Metropolis Works plant in Illinois, which remains the only uranium conversion plant in the US. Solstice expects to produce over 10,000 metric tons of UF6 in 2026, backed by a substantial backlog of over $2 billion.
The US relies on only three Western conversion plants—Cameco in Canada, Orano in France, and Metropolis in the US—to meet its growing demand for nuclear fuel.
Strategic Implications for HALEU
This heavy reliance on foreign entities and a limited number of Western conversion facilities underscores the vulnerability of the US nuclear supply chain. As advanced reactors require specialized HALEU, expanding domestic enrichment and conversion capacities becomes a national security imperative. The current infrastructure highlights the urgent need for targeted investments and technological innovations to secure a resilient domestic fuel cycle.
