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.

Neutron-induced fission cross sections for eight americium isotopes (A = 239 to 244) are predicted with the nuclear reaction model code EMPIRE-2.19. The code incorporates advanced fission modeling, presented by describing the implementation of barrier penetration, transmission mechanism, and decay probabilities. The fission cross-section calculations for americium isotopes are compared to experimental data and evaluations from the ENDF/B-VI.8, JEFF-3.1, JENDL-3.3, or preliminary ENDF/B-VII libraries when available. An analysis of the first and second fission barrier heights validates the existing systematic trend for odd and even neutron numbers.
