CONTAINER FOR TRANSPORTATION OF SPENT FUEL FOR "¦+¦¦-1000" REACTOR Russian patent published in 2015 - IPC G21C19/06 

FIELD: transport.

SUBSTANCE: container includes housing where casing is placed, and protective cover. In the casing on lower diaphragm, sockets are installed with possibility to place removable cassettes in them. Inside sockets on lower diaphragm and above each socket on protective cover, butt-end spring-loaded elements are installed. The elements include cup, plunger and spring. To plungers the bearing ring is attached allowing tubular dampers of removable cassette vials to pass inside the ring. The cassette is installed on bearing ring with gap formation between butt ends of tubular dampers and lower diaphragm. On the butt-end spring-loaded elements between cup and plunger, plastic sleeves are installed with gap between their upper butt ends and plungers. The gap between butt ends of tubular dampers and lower diaphragm is equal to sum of gap size between upper butt ends of plastic sleeves and plungers and 0.3-0.5 of plastic sleeve height.

EFFECT: decreased risk of tubular dampers and removable cassette vial covers deformations in case of removable cassettes fall into casing sockets, casing with loaded removable cassettes fall into container and container fall.
