title = "Enrichment Interpolation for High-Assay Low-Enriched Uranium Fuel Macroscopic Cross Section for Polaris/PARCS",
abstract = "A method was developed to estimate a set of multigroup cross sections for core design by interpolating between a set of existing macroscopic cross sections at different fuel e nrichments. A Gaussian process (GP) interpolation method was used with adaptive sampling in order to minimize the number of required lattice physics calculations. The interpolation was applied to pressurized water reactor (PWR) fuel assemblies containing High-Assay Low-Enriched Uranium (HALEU) fuel pins. The accuracy of the interpolated cross section libraries was assessed by a direct comparison with a cross section set generated by a lattice physics calculation at the interpolated enrichment. A specified accuracy was achievable by using the adaptive sampling method.",
