Abstract Scope |
To minimize degradation of salt-facing components, it is important to understand the material and chemical factors that affect corrosion. Dating back to the MSRE, efforts toward controlling corrosion in molten fluoride salts focused on careful alloy selection, thorough salt purification, and additives for redox control. Recent work in chloride salts has revealed new insights into the behavior of chloride-salt-facing alloys.
This work highlights recent findings showing how controlling salt chemistry affects corrosion in chloride salts. New developments in salt purification and redox control additives are shown to have direct and measurable effects on corrosion. Model alloys are used to isolate the effects of alloy composition and microstructure. Spectroscopic techniques are used in conjunction with traditional characterization to measure new salt properties.
This work presents new progress toward understanding what matters most when controlling corrosion in nuclear and concentrating solar systems that use chloride salts coolants. |
