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 transport equation for monoenergetic neutrons with linearly anisotropic scattering has been solved numerically with a method developed by Carlvik. Homogeneous multiplying systems in the form of spheres and infinite slabs were studied with boundary conditions of no incoming neutrons. Tables are given of six or more eigenvalues for an average cosine of the scattering angle ranging from 0 to 0.3 and for various dimensions of the bodies. With increasing anisotropy, there is an increasing number of complex eigenvalues that extend to lower modes and larger bodies. For spheres, tentative curves of the eigenvalue spectrum are given.
