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.

A class of discontinuous finite element methods (DFEMs) is proposed for spatially discretizing the SN transport equation in multidimensions. Mesh cells are first subdivided into simplexes. Equations for the angular fluxes in a cell are then generated by computing the linear DFEM SN equations for a simplex on each subelement and assembling the equations over the subelements. The result is a (piecewise) linear continuous finite element method spatial discretization on the cell that is coupled discontinuously to its neighbors through the standard DFEM upwinding technique. The method is presented in two-dimensional Cartesian coordinates. Numerical experiments indicate the method has numerical properties that are suitable for a new SN spatial discretization.
