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 brief history of the extended transport correction for Legendre differential scattering cross-section expansions is presented in conjunction with calculations intended to investigate the validity of such expansions for the extremely forward-peaked scattering characteristic of that experienced by electrons. It is concluded from the results that approximate P11 cross sections obtained with the extended transport correction can yield excellent scalar flux solutions for electrons with energies between 10 keV and 1 MeV, even though P11 expansions are totally inadequate for representing the exact cross sections.
