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.

Total attenuation cross sections in six alloys at 662-keV photon energies are measured by a transmission method using a NaI(Tl) scintillation spectrometer. The cross sections for the photoelectric process and for coherent scattering are deduced using theoretical cross sections taken from recent publications and are subtracted from the measured total attenuation cross sections to get the incoherent scattering cross sections. Finally, effective atomic numbers for the total gamma-ray interaction and for the incoherent scattering process are obtained by interpolation from graphs of the respective cross sections versus atomic numbers. The results are compared with effective atomic numbers estimated using semiempirical expressions.
