Abstract Scope |
Long term simulations of the material performance of nickel alloys in molten salt reactors and concentrating solar power systems require accurate fundamental measurements of the alloy properties. Key properties that control the corrosion behavior in nonisothermal loops include thermogalvanic coefficients and the effective diffusion coefficients of alloy constituents. At present, measurements of effective diffusion coefficients for species such as Cr within relevant alloys are limited to only a few candidate materials. In order to close this gap, Argonne National Laboratory has been conducting an extensive campaign of fundamental property measurements using electrochemical techniques applied to a range of metal alloys. The extracted properties are in turn used to enable multiphysics simulations of the interactions between alloys and complex salts in full-scale systems over extended durations. |
