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.

An assembly of self-powered in-core neutron detectors has been tested for 6 yr over four fuel cycles in the Oconee 2 pressurized water reactor. The assembly contained both prompt-responding ytterbium and delayed-responding rhodium detectors. Two ytterbium detectors were paired with two rhodium detectors in the assembly. The experiment was conducted to define the long-term performance characteristics of the ytterbium detectors. The results show that the radiation sensitivity of the ytterbium detector, after an initial decrease of 15 to 20%, regenerates with exposure, becoming more sensitive than at the beginning.
