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.

The application of generalized perturbation theory, both time dependent and static, to burnup problems is discussed. Simple analytical forms, applicable for many cases of interest, are derived for the time-dependent expressions. The influence of changes in Φ(E,r) during the cycle on the production of the plutonium isotopes is calculated for a typical liquid-metal fast breeder reactor case, using perturbation theory. Comparison of the results with direct calculations indicates that perturbation theory gives satisfactory accuracy for this problem.
