Abstract As one of the Gen-IV (Generation Four Initiative) alternative reactors, molten salt reactor (MSR) has become a popular research topic again in recent years. Molten fluorides act as the nuclear fuel carrier and coolant in MSR. However, its highly corrosive to structural materials is a great barrier of the MSR development. The active dissolution of alloying elements is the main result of hot corrosion. Trace impurities, the formation of galvanic couples between different materials and temperature gradient in the molten salt system are the main driving forces of hot corrosion. The research status of hot corrosion and surface protection for structural materials in molten fluoride salts by domestic and foreign researchers are reviewed in the present article.
