| Abstract Scope |
Corrosion of structural alloys in molten salts is a recognized concern for the development of the Molten Salt Reactors (MSR). In an MSR, different materials will be present in the vicinity of each other in the molten salt environment. In static molten salt tests that are frequently used for evaluating materials corrosion, two factors have an impact on the sample corrosion rate have been investigated. First, the ratio of sample surface area to salt volume which dictates corrosion product saturation in molten salt. As corrosion products build up in the salt, the driving force for further corrosion may be reduced. Second, is the influence of the capsule material which affects the corrosion rate of test samples due to mass transport induced by activity gradients. These two effects will be presented for tests performed in molten FLiNaK salt at 700oC. |
