U.S. uranium concentrate production reached 2.1 million pounds of U3O8 in 2025, more than tripling 2024 output.

U.S. uranium concentrate production totaled 2.1 million pounds of triuranium octoxide, or U3O8, in 2025. U3O8 is the uranium-concentrate form identified by the U.S. Energy Information Administration as the base component of nuclear-reactor fuel.

The 2025 production volume was more than three times the amount produced in 2024. It was also the highest annual U.S. U3O8 production level since 2017.

The measurement covers domestic uranium concentrate production and is expressed in pounds of U3O8. It does not represent enriched uranium, fabricated nuclear fuel, reactor output, or uranium-reserve volume.
