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 energy distribution of neutrons, from the source energy of 14 MeV down to the (n,2n) threshold, can be approximated by effective one-group cross sections for such high and medium mass number elements as lead, copper, zirconium, and iron. The same is true for 238U, when the fast fission factor ϵ is applied in a special manner to account for the added multiplication below the (n,2n) threshold. Two groups are required to obtain a reasonable description of the amplification in beryllium.
