General Matter and Centrus Target Vastly Different HALEU Capacities for Equal DOE Funding

A 30x Gap in Capacity Ambitions

The US Department of Energy's recent $900 million awards to Centrus Energy and General Matter have revealed strikingly different approaches to scaling domestic HALEU production. While both companies received identical federal funding and target 2029 for initial production, their annual capacity targets represent a nearly 30-fold gap in ambition.

General Matter's Aggressive Expansion

General Matter, a Founders Fund-incubated startup backed by Peter Thiel, has proposed an aggressively high production target. The company offered to produce 355 metric tons of HALEU annually for its $900 million award. To achieve this, General Matter recently signed a DOE lease on a 100-acre parcel at the former Paducah Gaseous Diffusion Plant in Kentucky. This massive site will serve as the foundation for their rapid scale-up, anticipating full operations shortly after their 2029 start date.

Centrus's Phased Approach

In stark contrast, Centrus Energy committed to a much more conservative initial capacity. For the same $900 million, Centrus proposed delivering 12 metric tons of HALEU annually. Centrus plans to bring this initial capacity online in 2029, with full production rates not expected until after 2030. However, Centrus holds a distinct advantage: it is currently the only NRC-licensed facility in the US producing HALEU-grade uranium. With nearly three years of production experience and close to one metric ton delivered as of summer 2025, Centrus offers proven operational readiness.

Both companies target 2029 for initial production, representing a nearly 30x gap in annual capacity ambition for identical funding.

This disparity in capacity targets for equal funding underscores the complex trade-offs in the US enrichment rebuild. The DOE is effectively balancing Centrus's proven regulatory and operational track record against General Matter's massive, albeit unproven, scale ambitions. Both companies have already secured HALEU offtake agreements with advanced reactor developers, ensuring that their respective output will be absorbed by the growing advanced nuclear market.
