Package for shipping dangerous materials to ensure the containment of these materials under conditions of severe accident. A containment enclosure of austenitic stainless steel, constituted by a single part devoid of orifices and of joints other than welds, has the shape of a cylinder of revolution closed at its two ends which are of convex shape. The wall of this enclosure is of a substantially uniform thickness without sudden variations including the area of the welds. Two axial shock absorbers, each formed by a section of metal tube preferably of the same cross-section as the above enclosure, are positioned on the end of the latter so that they are coaxial therewith. A support ensures the storage and the handling of the assembly are provided, as well as if necessary, removable means adapted to ensure the wedging of the dangerous materials inside the enclosure.
