  • Publication number: 20250205794
    Abstract: A reactor vessel cutting device, including a hoist system; a mechanical cutter; and a cutter carriage secured to the hoist system to be suspended by the hoist system. The cutter is secured to a carriage body of the cutter carriage to be carried by the carriage body. The cutter carriage includes a stabilization system secured to the carriage body and operable to hold the cutter carriage against a vessel wall of the reactor vessel. The cutter carriage is operable to apply the cutter to the vessel wall in a mechanical cutting operation when the cutter carriage is held against the vessel wall by the stabilization system. The hoist system is configured to bear the weight of the cutter and the cutter carriage during the mechanical cutting operation and the stabilization system is configured to carry cutting forces generated during the mechanical cutting operation.

  • Patent number: 12100522
    Abstract: An apparatus for volume reduction of material removed from a hazardous environment. The apparatus includes a shielded housing for receiving a workpiece therein, at least one cutting unit having a cutting head operable for contactless cutting, and a drive unit for rotating the at least one cutting unit around a main axis so the cutting head cuts the workpiece.

  • Publication number: 20240006086
    Abstract: A system and a method for simulating an operation of one or more automated tools within a nuclear facility. The system includes a communication component to provide access to one or more computing devices, one or more local controllers for processing command requests from the one or more computing devices for the one or more automated tools, and a processor in communication with the communication component and the one or more local controllers. The local controllers may be programmable logic controllers. The method includes using the local controllers for processing command requests received from the computing devices to generate process values for the one or more automated tools, and operating a processor use the process values to animate a three-dimensional model and generate one or more views of the animation of the three-dimensional model to be displayed at one or more computing devices.

  • Publication number: 20230400529
    Abstract: A robotic system for manipulating an electrical component between a first location and a second location, the system comprising: a movement element for moving a manipulation tool between the first location and the second location; the manipulation tool having one or more gripping elements for engaging the electrical component by grabbing the electrical component at the first location when the manipulation tool is positioned adjacent to the electrical component; and a testing system for implementing an electronic test of the electrical component while the electrical component is engaged by the manipulation tool, the testing system implementing the electronic test before the manipulation tool releases the electrical component; wherein upon reaching the second location the manipulation tool disengages with the electrical component, thereby reversing said engaging.
