A set of PuO2 samples subjected to different processing conditions was characterized by SEM/EDS to explore how variations in process conditions affect morphology. The samples display distinctive differences in morphology at a micrometer scale (Figure 1), correlated to changes in calcination temperature (300 and 800 �C) and the concentration of nitric acid used during precipitation. We discuss the potential for using morphological features as a nuclear forensics process signature for PuO2? produced by Pu(III) oxalate precipitation.LLNL-ABS-599017. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
