【Abstract】 Molten salt electrolysis is the vital unit of dry reprocessing technology for spent fuel. The corrosion environment of this unit is complex and harsh, involving a coupling corrosion such as high temperature( ≥ 500℃), chloride molten salt,liquid metal cadmium and atmosphere, etc., which brings great challenges to the material selection of the container. In this paper, the corrosion conditions of container structural materials are analyzed and the research progress in container structural materials is summarized. Finally, the research direction of the container structural materials is prospected.更多还原
