| Abstract Scope |
Material corrosion is a significant concern for the deployment of molten salt reactor (MSR) which is a generator-IV reactor concept with the great advantages of low-pressure primary system and high-temperature power cycle. Considering the lack of the molten salt corrosion study under flow conditions, the present study performed a corrosion test of 316 stainless steel (316 SS) in a NaCl-MgCl2 molten salt natural convection loop at the temperature of 700 ℃ for 1000 hours. The cross sections of the 316 SS corrosion samples are investigated by material characterization methods including SEM and XRD. Through comparing the 316 SS corrosion samples at different positions of the loop, the corrosion behavior at different temperatures and the thermal driven corrosion mechanism are analyzed. The design and preliminary results of a thin-layer activation analysis system to study corrosion of 316SS in molten salt flow loops in-situ will finally be presented. |
