This report provides information on the inventory of spent nuclear fuel (SNF) in the United States located at Nuclear Power Reactor and Independent Spent Fuel Storage Installation sites, as well as SNF and reprocessing waste located at U.S. Department of Energy sites and other research and development centers as of the end of calendar year 2021.
The purpose of this design analysis is to determine the accuracy of the SAS2H module of SCALE 4.3 in predicting isotopic concentrations of spent fuel assemblies. The objective is to develop a methodology for modeling assemblies similar to those evaluated within this analysis and to establish the consistency of SAS2H predictions. The results of this analysis may then be applied to future depletion calculations using SAS2H in which no measurements are available.
This report describes the characterization plan, methods, and results for light water reactor (LWR) Materials Characterization Center (MCC) spent fuel Approved Testing Material (ATM)-101. ATM-101 is spent fuel from H. B. Robinson, Unit 2, Assembly B0-5, a moderate-burnup, pressurized water reactor (PWR) fuel that released very small quantities of fission products and fission gas from the fuel during commercial operation.
