Abstract

For the transportation and long time storage of radioactive waste, especially of spent fuel elements, in suitable geological formations, there are needed multi-layered containers which guarantee a tight sealing even for a long period of time, are corrosion resistant to salt liquors, without being too expensive and too heavy. This is obtained by using for the individual layers of the container different metals or metal alloys which, from the outside inwardly, always are more noble (positive) in the electromotive (electrochemical) series.
