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.

One option for particle and power handling in the International Thermonuclear Experimental Reactor (ITER) is the creation of a low-pressure (∼10-mTorr) gaseous divertor. The divertor would have a long channel over which energy would be removed from the plasma by radiation, and the plasma pressure would be balanced by a change inflow velocities and neutral pressures entering the sides of the channel This combination should substantially reduce the ion energy and ion flux that impact the eventual end of the divertor channel. For this concept to work, momentum must be removed from the plasma by the neutral atoms and molecules. Plasma parameters were taken from a DDC83 code solution. A Monte Carlo treatment of the plasma-neutral interactions has been obtained using DEGAS, which includes charge-exchange, recombination, ion-neutral, and neutral-neutral elastic collisions. Results show that the momentum transferred to the side walls is insufficient by two orders of magnitude to achieve the pressure reduction needed. Each molecule that enters the plasma makes hundreds of elastic and inelastic collisions in the plasma and then is more likely to be ionized (transferring the momentum back to the plasma) than to travel to a wall.
