Uranium prices steady as EIA releases annual market report
The end-of-July spot price for uranium was $86.36 per pound, as reported by Cameco—roughly the same as it has been since February. Analytics firm Trading Economics reported a uranium futures price of $86.60 per pound, a figure that also has been holding steady since early April.
These updates come as the U.S. Energy Information Administration has released its 2025 Uranium Marketing Annual Report, which examines in detail multiple aspects of the U.S. uranium market. Data are derived from answers given in the Uranium Marketing Annual Survey, which collects information on contracts, deliveries (during the past year and projected for the next 10 years), purchased enrichment services, inventories, fuel assembly usage, and market requirements.

A time-dependent gas-phase absorption-desorption technique has been used to evaluate the isotope effect on the diffusive transport parameters of hydrogen isotopes in polycrystalline tungsten and the reduced activation ferritic-martensitic steel OPTIFER-IVb.Experiments have been run with both protium and deuterium obtaining their respective transport parameters of diffusivity (D), Sieverts' constant (Ks), the trap site density (Nt) and the trapping activation energy (Et). Isotope effects on these transport parameters are analysed and modelled. Because the classical isotope relation for diffusivity has not been fulfilled, quantum-statistical vibration theory has been applied to model the isotopic relation. The hydrogen vibration properties description in a metallic-host lattice allows deriving more accurate tritium transport parameters. A congruent isotopic variation of diffusion parameters related to the type of crystal structure, bcc, has been confirmed.
