METHOD FOR DRY STORAGE OF SPENT FUEL ASSEMBLIES IN CONTAINER Russian patent published in 2006 - IPC G21F9/34 G21F5/08 

FIELD: transport and storage of spent nuclear fuel.

SUBSTANCE: proposed method includes placement of fuel assemblies in transport package incorporating container and split damping casing designed so as to minimize lift of container when inserting it in split damping casing. Transport package is conveyed to storage place where container is freed of casing, whereupon spent fuel assemblies are kept in storage place. In the process spent fuel assemblies are first placed in container and then the latter is inserted in vertical position into split damping casing made in the form of removable drum with butt-end covering and base that functions as end lid of this drum. Charged container is installed on base, covered on top with removable drum, and the latter is fastened to base. Then split damping casing is secured to container, whereupon transport package is conveyed in transport position to storage place.

EFFECT: enhanced reliability of storage and transportation.
