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. During its temporary storage the fuel element container must be monitored with suitable measuring instruments. In order to make the monitoring as simple as possible, measuring probes are arranged on the inner wall surface of the shielding wall of the concrete shielding housing. The measuring probes are embedded in the concrete and are already in place and ready for use before the fuel element container is loaded into the concrete shielding housing.

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.

Abstract: The invention is directed to a concrete shielding housing for receiving and storing a fuel element container filled with spent nuclear reactor fuel elements. The container is suitable for transport and storage. The clear interior dimensions of the concrete shielding housing are somewhat larger than the outer dimensions of the fuel element container. The concrete shielding housing includes a pallet-type base and in the lower region of the housing there is provided at least one air inlet opening and in the upper region of the housing there is provided at least one air outlet opening. To prevent an uncontrolled conduction of moisture away from the interior of the housing to the ground or to the floor of a storage area or building, there is provided a collection pan arranged under the base plate of the pallet-like base. At least one axial bore extends clear through the base plate of the pallet-like base.

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 outer dimensions of the fuel element container are somewhat smaller than the clear interior dimensions of the concrete shielding housing. The concrete shielding housing includes a pallet-like base which can be moved about from one location to another with the aid of a suitable vehicle such as a fork-lift truck. The housing also includes the concrete shielding wall placeable upon the base, and a cover which can be placed atop the upper end of the concrete shielding wall. At least one air inlet opening is provided at the lower region of the concrete shielding housing and, at the upper region thereof, there is provided at least one air outlet opening.
