This report augments a US Department of Energy Topical Report on Actinide-Only Burnup Credit for PWR Spent Nuclear Fuel Packages submitted to the Nuclear Regulatory Commission (NRC). The purpose of the topical report was to obtain NRC approval on a generic burnup credit methodology. A major part of the methodology is the validation of the neutronics model used for designing the criticality control system. The validation methodology presented in the topical report established isotopic correction factors based on 19 isotopic samples. This report presents additional data points for isotopic validation. Measured and calculated isotopic quantities for nine samples from three spent fuel assemblies discharged from the Japanese Mihama-3 reactor are tabulated. 5 refs., 2 tabs.
