摘要： A method and an apparatus for visualizing an elastic wave propagation in a solid substance can be applied to a subject substance which is any one of a transparent body and an opaque body, and can detect SV waves (transverse waves) and SH waves (transverse waves) in elastic wave motion modes, and longitudinal waves, surface waves, and creeping waves. The visualization method comprises the steps of: generating elastic waves in a solid substance in response to electric signals; measuring a quantity of stress change in the solid substance in connection with elastic waves propagation in the solid substance; synchronizing a transmission timing of the electric signals with a measurement timing of the stress change; carrying out measurement while scanning a sensor; and imaging wave fronts of the elastic waves propagated in the solid substance by synchronously indicating the stress change as a function of time. The visualization apparatus comprises an elastic wave generator (8) for generating elastic waves in a solid substance (9) in response to an electric signals; an electric signal transmitter (7) for transmitting electric signals to the elastic wave generator (8); a sensor (1) for measuring elastic waves propagated in the solid substance; a sensor scanner (3) for controlling a scanning position of said sensor; a detected-signal recorder (2) for receiving and recording detected-signals from the sensor (1); a synchronizing circuit (10) for sending the detected-signals from the sensor (1) to the recorder (1) in synchronization with timing signals from the sensor scanner (3) and electric signal transmitter (7); and an elastic wave stress distribution display (4) for imaging stress distribution signals of the detected-signals from the detected-signal recorder (2).

摘要： A nuclear reactor comprising a reactor vessel, a core housed in the reactor vessel, an ultrasonic transducer mounted in the vicinity of the upper end of the core for emitting and receiving an ultrasonic wave pulse signal propagating above the core, means for rotating the transducer by a prescribed angle to scan horizontally the ultrasonic wave emitted from the transducer, a plurality of reflective means mounted in the vicinity of the upper end of the core in a manner to face the transducer for reflecting the ultrasonic wave signal emitted from the transducer, means for energizing the transducer, and means for displaying the ultrasonic wave signal reflected by the reflective members and received by the transducer in synchronism with the wave scanning motion of the transducer, wherein each reflective member comprises reflective surfaces each capable of reflecting the incident ultrasonic wave signal in a direction parallel with the incident direction and is mounted such that the distances of the reflective surfaces from the transducer are different enough from each other to prevent interference among the reflected ultrasonic wave signals.
