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 240Pu-to-235U fission cross-section ratio has been measured at 55 discrete energies between thresh-old and ∼10 MeV using the 7Li(p,n)7Be and D(d,n)3He reactions as neutron sources. The sample masses were measured by (a) calculated specific activities and low geometry alpha counting, (b) by mass spectrographic isotopic dilution analyses, and (c) by comparing the relative thermal fission rates of one of the 235U samples with 240Pu samples containing ∼9% 239Pu.
