| Abstract Scope |
Evaluation of the corrosion performance of potential structural alloys for use in the molten fluoride salt reactors has recently been performed using isothermal static corrosion environments. Simultaneous exposure of dissimilar materials (i.e. corrosion capsule differing from the corrosion sample) to molten salt has been shown to influence the corrosion behavior of both materials. Typically, preferential corrosion of a less noble material is achieved through a galvanic couple when two dissimilar materials are in direct electrical contact with one another. However, previous work shows that direct electrical contact may not be required for dissimilar materials to influence one another in a molten salt medium. The work presented here investigates the possible mechanism that drives non-galvanic mass transport in molten fluoride salts and how the mechanism can be slowed or perhaps eliminated in isothermal static corrosion environments. Corrosion exposures were performed for 1000 hours at 700 °C in molten FLiNaK. |
