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.

During the startup phase of the thorium high-temperature reactor (THTR)-300, control rod reactivity measurements are performed to meet the demands of the licensing authorities as well as to adjust the operating instrumentation. From several possibilities the inverse kinetic method has been chosen because of its easy implementation, high stability against disturbing signals, and great accuracy. An outline of the basic assumptions of various methods together with tests on the Kritische Anlage Hochtemperaturreaktor are discussed, the technical equipment for the THTR is described, and results of measurements for various rod configurations are given. Finally, the transition from the special startup equipment to the standard operating instrumentation is demonstrated.
