| Abstract Scope |
Molten Salt Reactors (MSRs) are considered promising candidates for next-generation nuclear reactors to meet the US energy demands. However, a significant challenge in the development of MSRs is the corrosion of structural materials. Developing a comprehensive understanding of the corrosion behavior of metals in molten salts is essential to create effective corrosion mitigation strategies for MSRs. Multimodal characterization techniques, including focused ion beam/scanning electron microscopy with electron backscatter diffraction, energy dispersive X-ray spectroscopy (EDS) and secondary ion mass spectroscopy, transmission electron microscopy with EDS and electron energy loss spectroscopy, and synchrotron-based scanning transmission X-ray tomography, are used to characterize pure Ni and Ni-Cr model alloys corroded in molten chloride salts. Quasi-in-situ TEM and in-situ synchrotron X-ray nano-tomography techniques are developed to observe the time-dependent evolution of molten salt corrosion at different time and length scales. |
