Pyrochemical (molten salt) processing of special nuclear materials combines severe operating temperatures, simultaneous exposure to aggressive oxidizing and reducing species, and critical product purity requirements, leading to stringent demands on new candidate materials requiring careful chemical characterization. Thermochemical modeling of chemical equilibria and carefully designed corrosion testing combined with modern instrumental analytical techniques (including SEM, EDS, WDS/microprobe, Auger, metallographic analysis, X-ray diffraction, and ICP spectroscopy) can be used to evaluate such phenomena as mechanisms of corrosive failure, selective leaching of alloy components, formation of insoluble phases, loss of thermal shock resistance, and intercalation.
