Section: claims

1. A device for handling rod-shaped members of a nuclear reactor comprising a reaction vessel, a reactor core containing rod-shaped members in the reaction vessel, a rotary cover on the reaction vessel, means for rotating the rotary cover, a slot in said rotary cover, a hoisting unit arranged on said rotary cover, means for moving said hoisting unit along said slot, a grip for grasping a rod-shaped member, transmission means interconnected with said hoisting unit for movement of said grip in the slot, whereby through rotation of said rotary cover and movement of said hoisting unit along the slot, said grip may be moved into position for transfer of any desired rod-shaped member. 2. Device according to claim 1 wherein said slot is disposed radially in the rotary cover. 3. Device according to claim 1 including a shielding box enclosing said hoisting unit and grip. 4. Device according to claim 3 including a carriage on which said hoisting unit rests, motor means for moving the carriage along said slot, and an expandable barrier between said carriage and the wall of said shielding box to prevent passage of vapors from said reaction vessel into said shielding box containing said hoisting unit. 5. Device according to claim 1 including an insertable shielding block across said slot to seal the interior of said reaction vessel. 6. Device according to claim 1 including an annular ring surrounding said rotary cover. 7. Device according to claim 6 wherein said annular ring has ducts into which said rod-shaped members may be transferred.
