​Controlling the corrosion phenomenon is a crucial issue, indeed, to be addressed by the nuclear industry: not only plant efficiency, but also plant safety are highly dependent upon it. The world is facing corrosion for a broad range of materials used in a wide variety of environments. Of course, metallic corrosion does occur in the hot, aqueous environment of water-cooled reactors, which are predominant in the world’s nuclear fleet. Advances achieved in controlling corrosion of the various components in theses reactors enable them to operate under safer conditions. Corrosion also occurs in nuclear fuel cycle back-end facilities (corrosion in acid environment in spent fuel treatment plants, waste container corrosion under storage or disposal conditions…). The nuclear reactor systems of the future will further extend the range of materials to be investigated and their contexts of use (corrosion by liquid metals of helium impurities).
As is depicted in this monograph, corrosion often looks like a patchwork of particular cases. The corrosion issues encountered and the related investigations are presented here in various chapters dealing with the nuclear world’s major branches, and are categorised according to their phenomenoly. This monograph illustrates ongoing research work, highlighting the outstanding results recently obtained.
