Abstract

The shipping cask comprises a vessel (3), and a removable basket assembly (11) within the vessel.
The vessel (3) has heat-conductive ribs (5) projecting from its outer surface, a layer of radiation-­ absorbing material covering its outer surface between the ribs (5), and flat heat-conductive fins (9) joined to outer edge portions of the ribs and bridging the spaces therebetween so as to form a watertight barrier support­ ingly and protectively overlying the layer of radiation-­ absorbing material. The basket assembly (11) includes, at its perimeter, heat-conductive formers (22) arranged so as to provide structural reinforcement, equilibration of mechanical shock forces, and good conductive heat transfer without objectionable impediment to convective and radiative heat transfer between the basket assembly and the vessel.
