Abstract

The invention is directed to a concrete shielding housing for receiving and storing a transportable fuel element container which is suitable for storage and filled with spent nuclear reactor fuel elements. The clear interior dimensions of the concrete shielding housing are somewhat larger than the outer dimensions of the container. At least one air inlet opening is provided at the lower region of the concrete shielding housing and, at the highest location of the housing, there is provided an air outlet opening. The air outlet opening is covered by means of a roof-like cover arranged in spaced relationship to the concrete shielding housing. The air outlet opening is surrounded by plates or metal strips or the like which are securely mounted to the housing and extend upwardly in the direction perpendicular to the housing. The upper edge of these plates terminate at a small distance from the roof-like cover. The air stream escaping from the interior of the housing is guided through a labyrinth-like path to the ambient.
