The degradation of materials in molten salt reactors (MSRs) must be understood before they can be constructed on a commercial scale. Among different degradation modes, corrosion in molten salts has been extensively studied, proceeding mainly via selective dissolution of Cr from the alloys into the salts. The corrosion rate is influenced by a variety of parameters, such as temperature, salt impurity content, and radiation flux. Radiation in particular will influence most of the parameters, however its effects on corrosion of MSR-relevant alloys have rarely been studied. In this project, a combined radiation and corrosion experiment system is constructed with an in-situ proton beam as the radiation source. Materials are simultaneously exposed to protons and a high temperature molten salt environment. This work will elucidate rates and mechanisms of irradiation-accelerated corrosion in molten salt, and will enable studies of how temperature, dose rate, and salt chemistry affect corrosion.
