  • STEAM GENERATOR NONDESTRUCTIVE EXAMINATION METHOD
    Publication number: 20070125175
    Abstract: A method of examining a steam generator heat exchange tube from the outside surface employing ultrasonic nondestructive inspection techniques. An ultrasonic transducer contacts the outside surface of the tube and transmits a pseudo helical Lamb wave into the wall of the tube chosen to have a mode that does not significantly interact with water in the tube. The reflected waves are then analyzed for changes in modes to identify defects in the wall of the tube.

  • Method of repairing a metallic surface wetted by a radioactive fluid
    Publication number: 20070031591
    Abstract: The wetted surface of a pressure vessel, a structural internal or a weld is repaired by removing the contacting radioactive fluid, forming a powder mixture of metallic particles and ceramic particles and then spraying the powder mixture on the formerly wetted surface to form a protective cold sprayed coating thereon. As-deposited coatings having a surface smoothness of 125 RMS or better may be nondestructively examined by ultrasonic, eddy current or dye penetrant tests without a preliminary grinding step.
