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.

The effects of the thermal-barrier potentials ɸb on the central-cell electron energy confinement are theoretically and experimentally investigated in the GAMMA 10 tandem mirror. In particular, the scaling of the central-cell electron temperatures Te with “the central-cell electron-confining potentials” ɸb is studied on the basis of the electron energy-balance equation and the generalized Pastukhov theory. The obtained theoretical scaling of Te with ɸb is then compared with the experimentally observed relation between these two parameters. In GAMMA 10, the main tandem-mirror operations are characterized in terms of(i) a high-potential mode having kV-order plasma-confining potentials, and (ii) a hot-ion mode yielding fusion neutrons with 10-20 keV bulk-ion temperatures. In this report, the scaling of Te with ɸb covering over these two representative operational modes is investigated, since the scalings of Te or the dominant parameters which determine Te have been remained for a long time as an unresolved important issue for tandem-mirror plasmas. It is found that the data in the two representative operational modes of the high-potential and hot-ion modes in the GAMMA 10 tandem mirror are in good agreement with the theoretically derived scaling formula, though the heating-source parameter dependence in the electron energy-balance equation is quite different in the two modes.
