Leading the charge: INL’s role in advancing HALEU production
Idaho National Laboratory is playing a key role in helping the U.S. Department of Energy meet near-term needs by recovering HALEU from federal inventories, providing critical support to help lay the foundation for a future commercial HALEU supply chain. INL also supports coordination of broader DOE efforts, from material recovery at the Savannah River Site in South Carolina to commercial enrichment initiatives.

The influence of the Hall effect on the current distribution and the plasma flow was investigated using two-dimensional numerical simulation for a self-field MagnetoPlasmaDynamic (MPD) thruster consisting of a short cathode and a flared anode. When the Argon mass flow rate and the total discharge current were set to 0.8 g/s and 5 kA respectively, the result with the Hall effect showed that concentrations of current density on the root of the cathode and on the edge of the flared anode were found. Such a highly skewed current lines near the cathode are caused by large local Hall parameters, which also lead to a large potential drop near the cathode surface.
