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.

Effects of the bumpy field component on the bootstrap current in the low-collisionality regime are discussed for L = 1 helical plasmas. It is usually considered that the bumpy field component or toroidal mirror ratio suppresses the bootstrap current in helical plasmas since it is a symmetry-breaking component. In the Heliotron J device, however, it has been observed that the direction of the bootstrap current can be changed according to the magnitude of the bumpy field component. In this study, we calculate the bootstrap current in the low-collisionality regime using a model magnetic field spectrum and discuss the condition under which the reversal of the bootstrap current direction occurs.
