Abstract
An improved container for transportation or storage of radioactive substances, especially spent nuclear fuel elements, has a cylindrical open-top thick-wall metallic body for shielding gamma radiation. A liner for the container has a top peripheral flange engaged with the bottom of a counterbore in the container open top. A thick gamma-ray shielding cover for the lining is disposed in the counterbore and screw means detachably secure both the lining flange and the cover to the body independently. The body has exterior generally parallel spaced cooling fins transversely intersected by flanges of lesser height to minimize fin cracks extending into the body. Neutron shielding is disposed in the exterior spaces between the fins and the flanges.
