Title:
METHOD AND DEVICE FOR DETECTING DEFECT OF MATERIAL
Document Type and Number:
Japanese Patent JPS608746
Kind Code:
A
Abstract:
The lip of the inner radius of a nozzle mounted through the wall of a nuclear reactor vessel is sandwiched between a transmitter and receiver of ultrasonic sound. The transmitter scans the internal surface of the nozzle lip while maintained a constant average distance from a receiver scanning the nozzle surface on the reactor vessel side of the lip. The two surfaces intersecting to form the inner radius vary in angle as the surfaces are scanned by the transmitter and receiver. Linkage is shown between the transmitter/receiver and the boom with which they are caused to sweep the lip to simultaneously accommodate the saddle shape of the inner radius and the varying angle between the lip surfaces.
