ABSTRACT OF THE DISCLOSURE: A container for transporting and/or storing irradiated nuclear fuel elements. The container includes a holding vessel made of cast iron containing nodular graphite and having an opening at one of its ends for receiving the materials to be stored therein and a cover for sealing the opening so as to be gas-tight with respect to the ambient. In order to weld a cover to the vessel without the necessity of conducting a follow-up heat treat- ment operation, an end ring made of cold-weldable material is mounted on the vessel at its opening. The end ring includes a connecting extension which is fused with the vessel when the latter is made by casting. After the vessel is filled, a cover made of a material having a structure similar to that of the end ring can be welded to the latter. In this way, a subsequent heat treatment of the vessel which would otherwise be necessary is avoided. The vessel and end ring can be viewed as being the vessel assembly and a method of making this assembly is also disclosed.
