METAL-CONCRETE CONTAINER FOR TRANSPORTATION AND/OR STORAGE OF USED ASSEMBLIES OF FUEL ELEMENTS OF NUCLEAR REACTORS Russian patent published in 2006 - IPC G21F5/08 

FIELD: storage and transportation of used nuclear fuel.

SUBSTANCE: metal-concrete container for transportation and/or storage of used assemblies of fuel elements of nuclear reactors has case with bottom, internal protection air-tight cap, edge damping members. Casing with central cell is inserted inside cavity of case. Peripheral cells are disposed around central cell for mounting housings with used assemblies of fuel elements. Peripheral cells are made in form of tubular members that are mounted to have spaces in relation to internal protection air-tight case and bottom of case. Casing has longitudinal rod members disposed around circle in relation to central cell of casing. Container has first and second sheet members which are mounted along height of case and are connected for disconnection by means of longitudinal rods. Edge damping members are made in form spring-shaped members and they are mounted onto internal protection air-tight cap each in opposite to corresponding cell of casing for interaction with housing under normal conditions of exploitation of metal-concrete container.

EFFECT: higher safety of handling of loaded container.
