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.

Plasma startup and operating issues are examined for a burning plasma using WHIST [1] simulations of the Fusion Ignition Research Experiment (FIRE) design [2]. Fueling and density profile control issues are illustrated through pellet launch from the inboard side of the plasma. Auxiliary fast wave ion cyclotron heating and current drive are used to identify plasma startup and burn control issues. It is shown that the current rampup and bootstrap current strongly influence the evolution of the safety factor, and can be tailored to produce sawtooth-free operation for about 20 seconds of burn in well-confined high confinement mode (H-mode) plasmas. Furthermore, it is also possible to maintain a reversed magnetic configuration that could allow access to the improved core confinement seen in present experiments. Access to H-mode operation is influenced by the fueling, heating and current startup waveforms. Maintenance of H-mode conditions may require either hysterisis in the high to low confinement (H-L) back-transition or continued auxiliary heating if the fusion power is insufficient.
