IMPROVEMENTS IN OR RELATING TO CHUCKS, PARTICULARLY FOR USE IN INSPECTING FUEL ELEMENTS OF NUCLEAR REACTORS
A chuck designed for use in inspecting reactor fuel elements and adapted to grasp the element in a predetermined longitudinal position with respect to the chuck is described. The chuck automatically rotates and stops at predetermined angular positions. The chuck contains a fixed plate on which a movable plate is mounted for rotation. There are movable jaws mounted in the movable plate that are normally resiliently urged toward the center of the chuck. Cperating members are provided for moving the jaws outward. The members are comprised of rotary cams movable independently of the movable plate, each cam is positioned to operate one of the jaws through an intermediate lever pivotally mounted on the fixed plate. Means are provided for rotating the movable plate. Rotation is controlled by electric switches actuated by the movable plate at predetermined angular positions. The jaws are provided on their gripping surfaces with friction linings. Electric motors rotate and control the cams and the movable plates. (N.W.R.)
