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 neutron capture cross sections of 240Pu and 242Pu were measured in the energy range from 50 to 250 keV, using 197Au as a standard. Neutrons were produced via the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector. A flight path as short as 66 mm was used in the measurements to obtain a sufficient signal-to-background ratio. An overall uncertainty of 7 to 11% was obtained for 240Pu and of 10 to 15% for 242Pu. In the region of overlap between 50 and 90 keV, the presented data agree with our previous results. They confirm the existing data for 240Pu. Discrepancies up to 30% for 240Pu and 242Pu were found in the evaluated ENDF/B-IV files while KEDAK 3 fits reasonably well to the experimental data.
