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.

Integral neutron capture and neutron fission cross sections have been measured for the 276-day 254gEs. Thermal cross sections and resonance integrals were evaluated using a cadmium filter technique. Capture cross sections were determined from alpha-particle spectrum measurements following neutron irradiations with cobalt flux monitors. Fission cross sections were measured using fission track detection techniques with 233U monitors. The fission cross-section values compared favorably with an absorption cross-section determination from a burnout experiment of 253Es-254Es. The integral neutron capture and fission cross sections determined for 254gEs are: = 28.3 ± 2.5 and Ic = 18.2 ± 1.5 b, and = 1970 ± 200 and IF = 1200 ± 250 b.
