| Abstract Scope |
In this study, attempts were made for monitoring the in-situ corrosion of Inconel 625 alloy in eutectic molten NaCl-MgCl2 salt using natural convection microloop through the thin layer activation technique. Radioactive isotope tracers were generated by a 16 MeV proton irradiation on a thinned tube section of the hot leg. Using High-Purity Germanium gamma-ray detectors located at different locations, the dissolution of the irradiated Inconel 625 was in-situ monitored through the activity measurement of the radioactive isotope tracers. At the same time, the transport of the dissolved isotope tracers was also in-situ monitored at different microloop locations. After the corrosion test, the Inconel 625 microloop tube was cut into different sections for the understanding of the alloy microstructure, corrosion products, and dissolution of elements using SEM/EDX. Based on the obtained results the elemental corrosion mechanism is discussed to understand the corrosion kinetics of Inconel 625 in molten NaCl-MgCl2 salt. |
