| Abstract Scope |
Molten salt reactors (MSRs) represent a promising direction for advanced nuclear energy systems due to their potential for enhanced safety, efficiency, and fuel utilization. However, the interaction of molten salts with structural materials presents significant challenges, primarily through the mechanism of corrosion. To investigate the corrosion mechanisms and test solubility limits of molten salts in-situ, we have developed a laser-based technique in unison with a mass spectrometer to probe the molten salt, which rests in a crucible made of structural material, in an air-tight chamber in liquid phase (done via heating filament) to produce vapor/plasma. This plasma is carried to the mass spec for isotopic analysis, measuring the concentration of impurities such as dealloyed material from the structural material in the molten salt. The laser probing is done periodically to observe isotopic changes in the molten salt, and eventually see a saturation point for impurities within the molten salt in-situ. |
