Analysis of the Saxton plutonium criticals using WIMSD4M and DIF3D

If excess weapons plutonium is to be used as fuel in light water reactors (LWRs), it will be necessary to verify that the reactor physics characteristics of such fuel can be predicted reliably. As one part of a comprehensive weapons plutonium LWR fuel benchmarking effort, Texas A&M University has modeled the criticality experiments of the Saxton Plutonium Program (SPP) using WIMS-D4M (with its ENDF/B-V library) and DIF3D.
