  • Radiation hardened ultrasonic cleaning system
    Patent number: 11351578
    Abstract: In a submersible ultrasonic cleaning system for use in highly radioactive environments (e.g., cleaning radiated nuclear fuel assemblies), a bond between energy producing transducers and an radiating wall is strengthened with a polyurethane adhesive such as Permabond PT326, or 3M DP-190 adhesive. In various diagnostic tests, one or more of the transducers are operated in an energy-transmitting mode while one or more other transducers are operated in an energy-detecting mode to detect a weakened transducer/wall bond and/or acoustic conditions of the working fluid.
    Type: Grant
    Filed: May 24, 2017
    Date of Patent: June 7, 2022
    Assignee: DOMINION ENGINEERING, INC.
