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 dynamics of continuously fueled fission reactors based on an isothermal and nonlinear description of neutron/nuclide interactions is considered. In general, and for a plausible range of operational fueling conditions, such systems are absolutely stable, at most displaying converging spiral phase-space trajectories.
