Corrosion Behavior of Structural Alloys in Molten Fluoride Salts for Next Generation Nuclear Reactors

摘要

Molten fluoride-based salts are promisingrncandidates for coolant or thermal exchange media inrnfluoride-salt-cooled high-temperature reactors (FHR)rndue to their superior thermo physical propertiesrnincluding high boiling point, good thermalrnconductivity, and high volumetric heat capacity [1].rnHowever, molten salts are corrosive to structuralrnalloys used in nuclear reactors. Corrosion occursrnlargely by the thermodynamically driven dissolutionrnof typically passive oxide layers [2-3].
