Estimating the term…
A device for changing the location of fuel elements and control rods in a core reactor with a guiding mast which is mounted on a movable working platform for rotation about a vertical axis and which is provided with a gripping body for grasping the fuel elements and control rods, said gripping body being suspended on a lifting mechanism and being displaceable in vertical direction within the guiding mast while being prevented from rotating relative to the guiding mast. The device furthermore comprises winding means for storing supply lines which are introduced at the top into the guiding mast and the gripper body. The device also includes power operated means for actuating the lifting mechanism. The winding means and lifting mechanism rotate with the mast and are so arranged in the mast that any water dripping therefrom runs down the inside of the mast. Supply conduits leading to the mast are connected thereby by slack loops which permit 360.degree. of rotation of the mast.
Apparatus for relocating fuel elements and control rods in a core reactor in which a tubular mast is rotatable on a vertical axis on a horizontally movable platform and is provided with a gripper body, said apparatus including means nonrotatably but reciprocably guiding said gripper body for vertical movement in said mast, lift cable means connected to the gripper body and flexible conduit means also connected to the gripper body, drive means for the cable means and storage means for the conduit means said drive means and storage means being carried by said mast and rotating with the mast when the mast rotates about said axis.
