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 fission cross-section ratios 241Am: 235U and 243Am: 235U were measured as a function of neutron energy from 0.2 to 30 MeV using ionization fission chambers, the threshold cross-section method, and the time-of-flight technique at the Lawrence Livermore National Laboratory 100-MeV electron linear accelerator. Our experimental procedure required accurate measurements of the isotopic composition of fissionable material within fission chambers containing a mixture of the threshold isotope (i.e., 241Am or 243Am) and 235U. The measured cross-section ratios, averaged over the neutron energy interval from 1.75 to 4.00 MeV, were 1.648 ± 0.046 and 1.391 ± 0.039, respectively.
