Fuel rod assembly and method for mitigating the radiation-enhanced corrosion of a zirconium-based component

摘要

There is provided a fuel rod assembly comprising a first component of a zirconium-based material. The first component (30) is in contact with or is located adjacent to a second component of a material different from the zirconium-based material, e.g. a nickel-based or iron-based alloy. A coating (32) is disposed on an outer surface (34) of the first component (30), which is effective to reduce an electrochemical corrosion potential difference between the first component (30) and the second component relative to an electrochemical corrosion potential difference between the first component (30) and the second component without the coating (32).
