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.

In order to support the development and deployment of uranium fuels with enrichment beyond 5%, additional criticality safety methodologies are needed to prevent the possibility of criticality accidents. Specifically, improved methodologies for computer code validation using evaluated critical experiments, particularly for dissolver systems, need to be developed. Potential candidate evaluations and methodologies are presented to evaluate the effect of heterogeneity for intermediate-enrichment uranium systems.
