| Abstract Scope |
Molten chloride salts are potential candidates for use in advanced nuclear reactors (ANRs) as coolants and heat storage media. Compatibility of structural alloys with chloride salts is currently being investigated. Previous studies have shown that the depletion of the least noble alloy constituent (e.g. chromium) from common alloys such as SS316H is the main corrosion pathway in chlorides. Effect of fission product additives on chromium depletion has not been studied before. This presentation will highlight the effect of europium, one of the most abundant fission products in ANRs, on chromium depletion. Pure chromium specimens were exposed in purified KCl-MgCl2 salt at 700 and 800 °C in molybdenum capsules. Separately, 0.5 mol % of Eu and EuCl3 were added to the purified salt to serve as simulated source of fission product. Mass change data and the depth of chromium depletion will be evaluated with respect to the source of fission product. |
