| Abstract Scope |
Molten Salt Reactors (MSRs) are among the leading candidates for next-generation nuclear reactors that can contribute to the US energy supply. However, a significant challenge in the realization of MSRs is the corrosion of structural materials. To understand the corrosion behavior of commercial alloys and develop effective corrosion mitigation strategies in the MSR environment, it is crucial to gain insights into the basic corrosion behavior of simple model metals and alloys in molten salts. Electron microscopy characterization techniques, such as scanning electron microscopy equipped with electron backscatter diffraction and scanning transmission electron microscopy equipped with energy dispersive X-ray spectroscopy and electron energy loss spectroscopy systems, are utilized to analyze the microstructure of pure nickel, nickel-chromium alloys, and additively manufactured stainless steels after corrosion in molten salts. These techniques enable the visualization of detailed microstructural changes that occur during the corrosion process, providing valuable information for understanding corrosion mechanisms in MSRs. |
