ABSTRACT:
A thermal protection shell for protecting the exterior walls of a radioactive waste container disclosed herein. The shell generally comprises a wall of heat conductive material, such as aluminum or magnesium, which circumscribes and engages the exterior of the waste container walls in intimate, heat-conducting contact under ambient temperature conditions. The thermal coefficient of expansion of the material forming the shell is chosen to be greater than the thermal coefficient of expansion of the material forming the container walls, which are typically steel, so that the heat-conducting contact between the shell and the outer walls is broken when the shell is exposed to a fire. The shell is formed in sections which are rigidly interconnectable by bolt assemblies formed from the same material as the shell itself. The use of such sections allows the shell to be easily mounted over existing radioactive waste containers, and adjusted to fit containers of different diameters.
