Latest Patents
One of Ashburn's latest patents is the "Narrow access scanning positioner for inspecting core shroud in boiling." This invention involves a method and apparatus for inspecting a core shroud by remote operation. The apparatus is a robotic scanning device designed to fit in the narrow space between the core shroud and the jet pumps. It can scan both azimuthally and vertically around the circumference of the core shroud. The scanning device provides gross positioning to the area of interest and precise motion control within a limited scanning range. The design features a thin wide arm that supports a bank of transducers, allowing it to pass through a 0.5-inch access opening while maintaining radial flexibility to adapt to surface contour variations. The transducer mounting includes a water jet thruster to ensure contact with the shroud during operation.
Another significant patent is the "Jet pump beam bolt retainer cutter." This apparatus is designed for the underwater separation of a jet pump beam from the inlet mixer of a jet pump in a nuclear reactor system. It effectively cuts a retaining piece that couples the beam with the inlet mixer, facilitating maintenance and operational efficiency.
