| Abstract Scope |
Molten salts play important roles in applications such as molten salt reactors (MSR), electrometallurgy, and concentrating solar power (CSP) systems. The ingression of impurities such as oxygen and moisture into these systems can lead to the evolution of the salt chemistry along with corrosion of high temperature alloys that contain the salts. In this work, we will present studies of the apparent kinetic properties of these corrosive impurities along with the concomitant effects on the salt’s chemistry and corrosivity. Specific results include redox alterations to the salt along with the precipitation of key insoluble species. We will also discuss results describing methodologies to monitor and control the presence of impurities within the salts. These experimental studies and accompanying technology development activities provide key insights and enable extended lifetimes for molten salt systems. |
