Mining and Milling
The nation will want 55,000 – 75,000 metric tons (MT) of uranium (U3O8) every year to hit the 2050 goal. At present, the nation solely produces 2,000 MT yearly and has procured 22,000 MT. In 2014, U.S. uranium manufacturing peaked at 2,263 MT. To fulfill future demand, the US should enhance its manufacturing by about 71,000 MT yearly.
Conversion Capability
U.S. would require 70,000 to 95,000 MT of uranium hexafluoride (UF6) conversion capability. Proper now, the nation has 10,400 MT of capability. The Metropolis Works facility, the nation’s sole UF6 converter, reopened in July 2023 after a six-year shutdown. Nonetheless, this restart alone is not going to be sufficient to satisfy rising demand.
Enrichment Wants
The U.S. wants to spice up its uranium enrichment from its present 4.4 million separative work items (SWU) per 12 months to between 45 and 55 million SWU to help 300 GW of nuclear capability. Technology IV reactors require high-assay low-enriched uranium (HALEU), enriched to 19.75%. At current, the U.S. depends on a single HALEU facility, producing solely 900 kg yearly. The DOE is taking steps to create a home HALEU provide chain by means of packages just like the HALEU Availability Program, which is backed by $700 million from the Inflation Discount Act.
