Abstract

A transportation container for radioactive materials, especially for irradiated fuel elements, has a cylindrical body of a material to shield gammaradiation. The exterior of the body is provided with spaced cooling ribs. In order to avoid the continuation of the crack into the container body occasioned by damage to the cooling ribs, as by a fall, the body is provided with spaced flanges, of lesser height than the ribs, extending transversely of and to and between the ribs so that any cracking or breaking off of a cooling rib will not occur at its base.
