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

摘要

It is possible to provide an ultrasonic detection device, an ultrasonic detection method, and an atomic power plant nondestructive inspection method which can effectively generate ultrasonic waves of sufficient intensity and can perform preferable inspection in a wide range. The ultrasonic inspection device (1) includes a laser device (5) which emits a laser beam of an adjusted output power and a volume inspection ultrasonic transmission unit (17) to which the laser device (5) emits the laser beam and which has a transmission diaphragm (39) for generating ultrasonic waves. The ultrasonic waves generated by the transmission diaphragm (39) of the volume inspection ultrasonic wave transmission unit (17) is applied to a structure member (77) so as to perform inspection.The transmission diaphragm (39) is made of titanium.
