SPENT FUEL ELEMENTS BUNDLES AMPULES LIFTING AND MOVING GRIP Russian patent published in 2019 - IPC G21C19/32 

FIELD: nuclear equipment.

SUBSTANCE: invention relates to the nuclear equipment, in particular, to the safety ensuring means during overloading of the RBMK-1000 reactor spent fuel elements bundles ampoules into the canisters by the electromechanical manipulator, and is intended for use in the dry storage canisters batching chamber or at the NPP. Grip includes a housing made of two pivotally connected parts. On the housing upper part, through the bearings unit a sleeve with equipped with a ball lock and bayonet slots a head attached thereto is installed. In the housing upper part, a beam on a spline connection is installed in the bushing placed between the sleeve and the head. By the flexible shaft the beam is connected to located in the housing lower part screw mounted in the threaded bushing. Through the bearing the screw is connected to the conical pusher, and between the conical pusher and the tabs inner surfaces above their axes of rotation mounted on the axes in the levers slots the rollers are placed. Levers are mounted on axles in the housing lower part bore.

EFFECT: enabling possibility of the fallen ampoule engagement, lifting and transporting by the electromechanical manipulator.
