ULTRASONIC DETECTION DEVICE, ULTRASONIC DETECTION METHOD, AND ATOMIC POWER PLANT NONDESTRUCTIVE INSPECTION METHOD

摘要

Provided are an ultrasonic inspection device, an ultrasonic inspection method, and an atomic power plant nondestructive inspection method that are capable of efficiently generating ultrasonic waves having a sufficient intensity and that are capable of carrying out preferable inspection in a wide range. Provided is an ultrasonic inspection device (1) including a laser device (5) that emits output-adjusted laser light and a volumetric inspection ultrasonic-wave transmitting unit (17) having a transmitting diaphragm (39) that generates ultrasonic waves upon being irradiated with the laser light emitted by the laser device (5), inspection being carried out by radiating the ultrasonic waves generated by the transmitting diaphragm (39) of the volumetric inspection ultrasonic-wave transmitting unit (17) on a structural member (77), wherein the transmitting diaphragm is formed of titanium.
