Abstract
The CONSTOR ADV is a transport and storage cask for spent fuel elements of the new generation. Its wall is a sandwich system composed of steel -- CONSTORIT - steel. CONSTORIT is a shield material consisting of iron aggregate frame and hardened cement paste that is hermetically encapsulated between the inner and out steel liner. The cask inventory causes high temperatures of up to 180oC within the cask wall requiring an improved wall design. Therefore, in addition to CONSTORIT, copper heat conducting elements are inserted between the steel liners.
