Latest Patents

One of his latest patents is an inspection tool designed for detecting cracks in jet pump beams of boiling water. This integrated apparatus utilizes eddy current technology to inspect the arms of jet pump beams while also employing ultrasound technology to scan the borehole region. The tool requires a specialized scanner that moves an eddy current coil in two dimensions over the complex machined surfaces of the arms. The scanner features a unique curved track design that maintains the orientation of the eddy current probe perpendicular to the inspection surface, allowing for thorough inspections of both flat surfaces and curved edges.

Another significant patent is the in situ inlet mixer cleaning system. This innovative apparatus allows for the cleaning of inlet mixers while they remain in their operating position within a nuclear reactor. The cleaning tool is inserted remotely into the inlet mixer through a secondary inlet opening. It utilizes a waterjet created from an ultra-high-pressure source to clean the internal surfaces of the inlet mixer. The system includes various components such as a nozzle cleaning tool, pumping systems, and a computerized process monitoring and control system, ensuring efficient and effective cleaning operations.
