Abstract
A method for reducing corrosion of metal components in a water-cooled nuclear reactor. A compound containing a platinum group metal, e.g. palladium, is injected alone in small amounts into the high temperature water of the reactor in the form of a solution or suspension. This compound decomposes under reactor thermal conditions to release atoms of the metal in an amount sufficient when present on the metal components to reduce the electrochemical corrosion potential of the metal components to a level below the critical potential to protect against intergranular stress corrosion cracking.
