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.

Optical model parameters are recommended for the analysis of neutron cross sections in the atomic number range 24 to 73 and 4- to 20-MeV energy range. Using the real well potential V and real well radius coefficient R in the combination VR2, unique energy-independent fitting parameters are obtained regardless of the initial estimates. Neutron data for iron up to 100 MeV are analyzed using uniquely determined energy-dependent parameters.
