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.

Data from a single defected fuel element operating in-reactor are used to develop a physically based model for describing the increased release of iodine and noble gas fission products to the primary coolant following a reactor shutdown and start-up. Iodines are only released on reactor shutdown, whereas both species are observed on start-up. A dependence on the decay constant of λ-3/2 is typically observed for these transient releases, indicative of a source of release from fuel cracking with little holdup due to transport in the fuel-to-sheath gap.
