Abstract
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.

Claim 1
Independent Claim
51 words
A multi-layered transportation and storage container for the long time storage of radioactive waste, especially fuel elements, in suitable geological formation consisting essentially of a container having at least three layers of different metals or metal alloys, said layers being increasingly noble in the electromotive series from the outermost layer inwardly.
Claim 2
Dependent Claim
51 words
A multi-layered transportation and storage container for the long time storage of radioactive waste, especially fuel elements, in suitable geological formation consisting essentially of a container having at least three layers of different metals or metal alloys, said layers being increasingly noble in the electromotive series from the outermost layer inwardly.
