| Abstract Scope |
Understanding the corrosion behavior of structural materials in molten salts under irradiation is essential for the successful deployment of molten salt reactors (MSRs). However, a significant knowledge gap remains regarding the effects of simultaneous irradiation during molten salt corrosion, as most prior studies have focused on sequential exposure. Simultaneous exposure may more closely replicate in-reactor conditions, but it is experimentally complex and limited to a few specialized laboratories worldwide. Sequential approaches—where corrosion follows irradiation or vice versa—are more accessible but may overlook key synergies between irradiation and corrosion. Here, both sequential and simultaneous experiments were performed at 700°C for 140 hours using 2.5 MeV protons and chloride salts. Advanced electron microscopy revealed distinct differences in degradation morphology and damage evolution, underscoring the impact of testing methodology. These results clarify the trade-offs between experimental simplicity and physical realism, and inform the choice of approach for future MSR materials research. |
