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.

A practical formula for sensitivity coefficients of burnup properties has been derived by means of a generalized perturbation theory. A differential method is employed. The resultant formula corresponds to an extension of the Williams formula, which is based on a variational method. The applicability of the proposed formula is investigated by calculating sensitivity coefficients in a typical fast breeder reactor and by comparing the results with those from the direct subtraction calculations. The physical meanings of components of the coefficients are discussed.
