Storage rack for nuclear fuel elements, consisting of a lattice construction, constituted by a first arrangement of parallel, vertical and equally spaced relatively long sheet elements, having sharply shaped contours and a second arrangement of parallel, vertical equally spaced relatively short aligned sheet elements, having sharply shaped contours, each bridging the distance between the relatively long sheet elements, such that a plurality of adjoining vertical storage cases is formed, having a rectangular horizontal cross section, each for receiving one nuclear fuel element. The relatively short sheet elements are provided with lugs at their opposite long edges engaging the surface of the relatively long sheet elements, said lugs fit in accurately formed slots in the relatively long sheet elements for connecting the sheet elements by means of a keying.
A storage rack for the storage of fuel elements of nuclear reactors consisting of a sheet metal lattice arrangement constituting a plurality of abutting similar vertical storage cases having a rectangular cross section, characterized in that said lattice arrangement is constructed of a plurality of mutually substantially perpendicular sheet elements having a sharply shaped contour, the sheet elements in one of the two perpendicular directions being continuous traversing sheet elements forming walls and extending over the widths of a plurality of cases of the lattice arrangement, two adjacent traversing sheet elements being spaced at a mutual distance substantially corresponding with the width of a storage case and all sheet elements in the other of the two perpendicular directions being narrow sheet elements each extending only substantially over the width of one storage case, the narrow sheet elements at the opposite long edges thereof being provided with lugs protruding from the edges, the traversing sheet elements having openings formed therein for receiving the lugs, said lugs having openings extending therethrough for receiving wedges, the opening in the lug being positioned on the opposite side of a traversing sheet element from the narrow sheet element when the lug is inserted through an opening in the traversing sheet element, and wedges insertable into the openings in the lugs so that the long edges of the narrow sheet elements may be pressed tightly against the traversing sheet elements.
A storage rack for fuel elements of nuclear reactors, consisting of a sheet metal lattice arrangement, constituting a plurality of adjoining equal vertical storage compartments of mainly rectangular cross section, each compartment storing one fuel element, characterized in that said lattice arrangement is constructed of a plurality of wide and narrow sheet elements, together forming walls of the compartments, said wide sheet elements being positioned mainly perpendicular to said narrow sheet elements and extending to define walls of a plurality of compartments and said narrow sheet elements extending over the width of one storage compartment, said narrow sheet elements being provided at their opposite longitudinal edges with lugs, said wide sheet elements having slots for receiving the lugs, each lug having a transverse opening for receiving a wedge, said opening after fitting of a lug through a respective one of said slots being positioned with a lug portion at the opposite side of the adjoining wide sheet elements, and a wedge insertable into said opening for tightly pressing each longitudinal edge of the narrow sheet element against the side of the adjoining wide sheet element.
