The device also comprises a jaw-shaped aperture 5 and a rotatable gripper hook 3. The insert 12 can be positioned as shown in Fig. 3 with the prongs 13, 14 facing outwardly when only control rod holders can be picked up since the thicker fuel element holders cannot enter the gap between the prongs 13, 14 and hence cannot be engaged by the hook 3. With the insert 12 in its alternative position (Figs. 1 and 4) only the fuel element holders can be picked up since the insert 12 prevents the control rod holders from getting far enough into the slot 7 to be engaged by the hook 3. The inset 12 may be replaced by one allowing more than two shapes to be selectively lifted.

Fuel elements are moved between an upper pool and a lower pool of a nuclear plant by a conveyor tube having an upper end at the upper pool and a lower end at the lower pool and extending at an acute angle to the vertical between the ends. A plurality of transport baskets can move through the conveyor tube, each holding at least one of the fuel. An upper transfer device at the upper end in the upper pool loads the fuel elements into or unloads them from the transport baskets. A lower transfer device in the lower pool loads fuel elements into or unloads them from the transport baskets. Each transfer device can hold two of the transport baskets that are displaceable for positioning above or below the conveyor tube and movable during displacement through the tube between a vertical transfer position and an angled transport position. 1. A system for transferring fuel elements between an upper pool and a lower pool of a nuclear plant , the system comprising:a conveyor tube having an upper end at the upper pool and a lower end at the lower pool and extending at an acute angle to the vertical between the ends;a plurality of transport baskets movable through the conveyor tube and into each of which at least one of the fuel elements can be placed for transport through the conveyor tube;an upper transfer device at the upper end in the upper pool for loading the fuel elements into or unloading them from the transport baskets; anda lower transfer device in the lower pool for loading fuel elements into or unloading them from the transport baskets, each of the devices being adapted to hold two of the transport baskets, the baskets being displaceable for positioning above or below the conveyor tube and being movable during displacement through the tube between a vertical transfer position and an angled transport position.2. The system defined in claim 1 , wherein the upper and the lower transfer device each have two pivot frames into each of which a respective transport basket can ...

SYSTEM FOR HANDLING FUEL ELEMENTS

A system for transferring fuel elements between an upper pool and a lower pool of a nuclear plant has a conveyor tube having an upper end at the upper pool and a lower end at the lower pool. A transport basket movable internally along the tube and into which at least one of the fuel elements can be placed can travel through the conveyor tube. A blocking element at one end of the tube that can fully close the conveyor tube at the respective end. A cable hoist has a traction cable guided through the conveyor tube for raising and lowering the transport basket through the conveyor tube. An intermediate partially closing blocking element offset from the fully closing blocking element in the tube is formed with a cable passage through which the traction cable can pass in the closed position. 1. A transfer system for transfer of fuel elements between an upper pool and a lower pool of a nuclear plant , the liquid level of the upper pool lying above the liquid level of the lower pool , the system comprising:a conveyor tube having an upper end at the upper pool and a lower end at the lower pool and extending between the upper and lower ends at an acute angle to the vertical;a transport basket movable internally along the tube and into which at least one of the fuel elements can be placed for transfer through the conveyor tube;a fully closing blocking element at one end of the tube that can fully close the conveyor tube at the respective end;a cable hoist having a traction cable guided through the conveyor tube for raising and lowering the transport basket through the conveyor tube; andan intermediate partially closing blocking element offset from the fully closing blocking element in the tube, movable between an open position allowing the basket to pass and a closed position blocking such passage, and formed with a cable passage through which the traction cable can pass in the closed position.2. The system according to claim 1 , wherein the fully closing blocking element is ...
