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.

A hybrid collocation-Galerkin-Sn method for solving the one-dimensional Boltzmann transport equation is presented. For problems with highly anisotropic scattering, this method offers many advantages relative to the standard Sn method. It is particularly useful for charged-particle calculations and can be implemented easily in standard Sn codes without changes to the standard solution algorithm. The hybrid method is compared with the standard method both theoretically and computationally.
