Centrus Energy's Monopoly on U.S. HALEU Production Highlights Supply Chain Gaps

The Sole Western Producer

As the United States pushes to revitalize its nuclear energy sector, the availability of High-Assay Low-Enriched Uranium (HALEU) has emerged as a primary regulatory and industrial focus. Currently, Centrus Energy holds a unique position in the market: it is the only company in the West holding an NRC license to enrich uranium up to 20% U-235, the threshold for HALEU. The company operates a bespoke centrifuge cascade at its American Centrifuge Plant in Piketon, Ohio.

Regulatory Hurdles and Supply Chain Realities

While Centrus' NRC license is a monumental regulatory achievement, it also highlights a significant vulnerability in the U.S. nuclear policy landscape. The broader HALEU fuel supply chain does not yet exist at scale to support the wave of advanced reactor deployments expected later this decade. Companies like Oklo, X-energy, and Antares are advancing their reactor designs, but they are heavily reliant on a single domestic supplier for their core fuel needs.

The broader HALEU fuel supply chain does not yet exist at scale to support advanced reactor deployments, creating a critical bottleneck for the industry.

To address this, the Department of Energy has been actively involved, as seen in its decade-long demonstration contract with Centrus, which has already yielded over 1,900 kilograms of HALEU. Furthermore, policy initiatives are encouraging diversification. For instance, Antares Nuclear has signed a supply contract with Urenco, which will produce HALEU at its Capenhurst facility in the UK by 2031, backed by UK government funding. This highlights a policy shift toward relying on trusted Western allies to bridge the domestic supply gap.

Future Policy and Market Implications

The current monopoly held by Centrus underscores the urgent need for streamlined NRC licensing processes for new enrichment facilities and fuel fabricators. Until the regulatory framework facilitates the entry of more domestic players, the U.S. advanced nuclear renaissance will remain constrained by the capacity of a single producer. Policymakers must continue to support capacity expansion and international partnerships to ensure a resilient, secure, and diversified HALEU supply chain.
