The invention relates to a method for cleaning a container, which is in particular a steam generator in a nuclear power plant. Iron oxide present in the container, e.g. B. dissolved with an alkaline reducing solution. It is envisaged that after the iron oxide has been dissolved, the solution that is still present is changed in order to subsequently dissolve copper and / or copper compounds. Only then is the container emptied. For example, after dissolving the iron oxide, the solution is cooled, its pH is raised, oxidizing conditions are set in it, and suitable chemicals for dissolving copper and / or copper compounds are added to the solution. |
