ABSTRACT:
The invention is directed to a container for the long-term storage of radctive materials such as irradiated nuclear fuel elements. The container includes a vessel-shaped base body made of a material selected from the group including cast iron and cast steel. The base body has an outer surface and an opening through which the radioactive materials to be stored therein are passed. A plurality of ribs made of corrosion-resistant material are formed on the outer surface of the base-body to partition this surface into a plurality of surface segments. A protective layer covers each of the surface segments to protect the same against corrosion. A cover is adapted for sealing the opening of the vessel-shaped base body. The ribs and their arrangement on the surface of the base body of the vessel make it easier to apply the corrosion protective layer and make the layer less sensitive to differential expansion stresses of the contiguous materials.
