Abstract Scope |
Molten Salt Reactors (MSRs) are among next-generation advanced nuclear reactors for the US power grid. Corrosion of reactor structural materials is a significant challenge in MSR development. To comprehend structural alloys’ behavior in MSR environments, understanding fundamental corrosion mechanisms of simple metals in simulated conditions is crucial. This research investigates the corrosion behavior of Ni-20Cr binary alloy under molten NaCl-MgCl2 salt at 700°C for various time periods, comparing responses in corrosion-only and stress-corrosion environments. The stress-corrosion experiments use a disc bending test setup, exposing the alloy to compressive and tensile stresses while in contact with the molten salt. Corrosion rates, microstructural changes, and mechanical properties are evaluated to elucidate material degradation mechanisms, informing more robust materials for high-temperature, corrosive environments. |
