    摘要： An ultra high pressure abrasive waterjet cutting apparatus for underwater cutting of structural components of a nuclear reactor is described. The cutting apparatus includes a multi-axis manipulator, an ultra high pressure abrasive waterjet (UHP) cutting nozzle coupled to the manipulator, a collection stand assembly, a collection hood movably coupled to the collection stand assembly, and a turntable having a non-movable center portion. The multi-axis manipulator is configured to mount on the non-movable center portion of the turntable or on the floor of the pool of water in which the structural component is positioned for cutting. The collection stand assembly is configured to mount on at least one of the floor and the wall of the pool of water. The cutting nozzle and collection hood are positioned on opposite sides of the structural component to be cut.

    摘要： A tool is disclosed for remotely inspecting and/or treating welds, pipes, vessels and/or other components used in reactor coolant systems or other process applications to, among other things, mitigate stress corrosion cracking in the welds, pipes, vessels and/or other components. The tool is placed at the entrance to a pipe or vessel and walks into the pipe or vessel to a pre-selected weld, pipe or vessel location or other component. Upon reaching the pre-selected weld, pipe or vessel location or other component, the tool anchors itself, then advances an end effector to inspect and/or treat the pre-selected weld, pipe or vessel location or other component.

    摘要： A lower housing having a lower chamber and a welding opening is fixed about an underwater weld site. The lower housing includes an upper opening, the lower housing being filled with water upon installation. A transport housing containing a welding unit in a dry state is lowered such that a bottom opening, closed by a closure element, registers with an upper opening of the lower chamber. Upon clamping the housings together, the lower chamber is at least partially evacuated. The closure element is then moved to an open position and the welding unit is lowered into the evacuated lower chamber to weld a patch to the vessel wall to overlay the damaged area.

    摘要： An ultra high pressure abrasive waterjet cutting apparatus for cutting nuclear reactor structural components is described. The cutting apparatus includes an ultra high pressure abrasive waterjet (UHP) cutting nozzle, movably coupled to a single axis manipulator, and a collection hood. The manipulator and the collection hood are coupled to a support frame and are configured to be positioned inside adjacent openings of a nuclear reactor top guide or core plate so that the cutting nozzle is in alignment with the collection hood. The manipulator includes a linear frame, a nozzle support plate movably coupled to the linear frame, and a motor operatively coupled to the nozzle support plate. The collection hood includes an elongate collection chamber having an elongate opening located so that the opening is in alignment with the cutting nozzle. The collection hood also includes at least one positioning cylinder coupled to the collection chamber and to the support frame which positions the collection chamber opening adjacent a top guide or core plate beam. The collection hood further includes an outlet port configured to be connected to a water filtration system.
