    Abstract: A tool for delivery of a testing element to a limited access location within a nuclear containment includes a rotation apparatus having a connection element that is configured to have an aperture that is formed generally centrally therein. A submersible machine is structured to carry the tool to a limited access location within a nuclear containment. The submersible machine includes a mount apparatus configured to be movably clamped onto a steam dam of a nuclear reactor apparatus and to drive the submersible machine circumferentially along the steam dam to inspect a plurality of jet pumps or other limited access locations of the nuclear reactor apparatus. The improved submersible machine advantageously further includes an adjustment table between the mount apparatus and a frame that carries the tool to enable rapid accurate positioning of the frame, and thus the tool, once the submersible machine has been mounted to the steam dam.

    Abstract: A nuclear component transfer device that incorporates a shielded canister into the mast design of a conventional nuclear refueling machine. A moveable mast telescopes within a stationary mast which is attached to a bridge for lateral positioning. The canister allows for the addition of shielding that is positioned with the movement of the moveable mast without additional motorized components to deploy the shielding during nuclear component movement. The nuclear component is drawn up into the shielded canister as the moveable mast lifts the nuclear component. The nuclear component is then placed into a transfer cart that is also fitted with a shielded canister. The transfer is made without exposing the nuclear components resulting in completely shield movement.

    Abstract: A telescoping mast with zero clearance which can be used in a fully automatic, relative positioning refueling machine. The telescoping mast consists of a series of nested tubes separated by spacers of unique design. Each spacer consists of an upper spacer assembly attached to the upper end of an inner tube segment nested in an outer tube segment and slidable inside the outer tube segment; and a lower spacer assembly attached to the lower end of the outer tube segment and slidable outside the inner tube segment. The spacer assemblies are preferably made of molded plastic, for example, polyethylene. Each spacer assembly is formed by a spacer ring and a plurality of corrugated members connected at one end to the spacer ring. The distal ends of the corrugated members of the upper spacer assembly contact the distal ends of respective ones of the corrugated members of the lower spacer assembly when the inner tube segment is in an extended position relative to the outer tube segment. Each of the corrugated members comprises a multiplicity of spacer blocks connected in series by a multiplicity of flexible beams. Bending of the flexible beams during compression of the spacer assemblies provides damping of the force produced upon impact when the inner tube segment drops relative to the outer tube segment, for instance, after the inner tube segment has been stuck and then slips relative to the outer tube segment.

    Abstract: A gripping and lifting device, especially for use with fuel elements and control rod means in a nuclear core reactor in which a carriage having a winch thereon supports a mast beneath the carriage in which is slidable a tubular body within which, in turn, is slidable a housing. Cables lead from the winch to the first body for vertical movement thereof while the housing has limited axial movement in the aforementioned body. On the lower end of the housing are two gripper devices, one for engagement with the control rods and the other for engagement with the fuel element. Separate actuators are provided for the two grippers and sensing devices are included in the structure for sensing the positions of the grippers. A feature of the arrangement is that when the body is elevated and the housing moves downwardly therein to a stopped position, the gripper for the fuel element is locked in its respective position.
