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.

To provide a convenient and reliable method for estimating the resonance heterogeneity effects, a multiregion equivalence relation will be derived for fast reactor lattice cells. It will be shown that the broad group cross sections of “each plate” in a multi-region problem can be calculated by using a cross-section set of the Bondarenko type. Moreover, for the special cases where the thickness of all the resonance plates is equal, the present formulation is shown to be equivalent to the two-sided E3 formulation of Meneghetti.
