Abstract

La présente invention concerne un réactif de décontamination oxydative pour l'élimination de la couche d'oxyde radioactif dense sur la surface métallique, le réactif comprenant un agent d'oxydation, un ion métallique, et un acide inorganique. Le réactif de décontamination oxydative de la présente invention est caractéristiquement préparé par ajout d'un ion métallique au réactif de décontamination oxydative classique contenant un agent d'oxydation et un acide inorganique. Lorsque le réactif de décontamination oxydative de la présente invention est utilisé, le potentiel électrique des parties métalliques du système primaire de la centrale nucléaire peut être régulé comme un potentiel passif en raison de l'ion métallique ajouté pendant la décontamination oxydative de la partie métallique primaire de la centrale nucléaire. Il est par conséquent possible d'inhiber la corrosion locale tout en réduisant significativement les déchets secondaires par le maintien du potentiel électrique de la partie métallique à un potentiel passif.
