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 ideas of the FN and transport PN approximation (TPN) methods in transport theory are suitably combined to formulate an accurate approximation scheme for the monoenergetic transport equation. The method involves the use of the singular integral equation for the surface flux as used in the FN method and angular flux representation of the TPN approximation. This leads to a consistent approximate scheme for the computation of angular flux.
