Abstract
A shipping cask for transporting radioactive material is disclosed herein which comprises an inner vessel having metallic, heat conducting walls, a plurality of heat conductive, mutually parallel ribs, wherein the inside edge of each is connected to the outside surface of the heat conducting wall of the inner vessel, a layer of neutron absorbing cement disposed over the exterior of the inner vessel and between the mutually parallel ribs, and a plurality of flat circumferentially disposed fin members, each of which has two opposing and mutually parallel edges that are welded to the outer edges of two adjacent ribs. The flat circumferentially disposed fin members dissipate heat conducted through the ribs generated by radioactive material within the inner vessel, and further serve both to support and protect the brittle layer of cement, as well as to provide a watertight barrier thereover so that the cask may be submerged or otherwise exposed to water without absorbing any significant amounts.
