INVESTIGATION OF DEPOSITED MATERIALS ON CARBON ELECTRODES IN MOLTEN SALTS BY IN-SITU X-RAY DIFFRACTION MEASUREMENTS

摘要

The procedure of in-situ X-ray diffraction (XRD) measurements has been developed for the observation of elctrodeposition process in molten NaCl-2CsCl salt to investigate the mechanism of pyrochemical process of nuclear fuel reprocessing system. In this study, the scattered X-ray from electrodeposited nickel in carbon container filled with NaCl-2CsCl melt was measured by reflection mode at BL19B2 and BL46XU beamlines in SPring-8 as the preliminary experiment. The time dependence of the electrodeposited nickel in NaCl-2CsCl melt at 923K was observed by the in-situ XRD measurements.
