摘要： In an ultrasonic inspection method or ultrasonic inspection system in which an ultrasonic wave is propagated to an test object via a medium such as a liquid or a gas, an incident position of the ultrasonic wave is accurately and reliably identified. In an ultrasonic inspection method based on an immersion technique, an optical irradiator is mounted on an ultrasonic wave transmitting/receiving unit, an optical marker is irradiated from the optical irradiator to the test object, and an irradiated position of the optical marker is imaged using imaging equipment in order to perform inspection.

摘要： The present invention provides a method and apparatus for an ultrasonic inspection of a penetration of a reactor pressure vessel, especially, a welded portion of the penetration. In the ultrasonic inspection, a position (inspection position) of an ultrasonic probe relative to a portion to be inspected can be identified without an effect of the surface of a portion to be inspected.The ultrasonic probe of the ultrasonic inspection apparatus, which is pushed onto the outer surface of the reactor pressure vessel, transmits and receives an ultrasonic wave to and from a penetration having a welded portion while changing an incident angle of the ultrasonic wave. Based on a result of reception of an echo obtained by the reflection of the ultrasonic wave on the inner surface of the penetration, an inclination angle of the penetration relative to a wall surface of the reactor pressure vessel is measured. A circumferential direction position of the penetration, which corresponds to the inclination angle, is calculated based on the relationship of an inclination angle and a circumferential direction position, which have been calculated in advance. Then, the circumferential direction position can be obtained as information on the inspection position.
摘要翻译：本发明提供了一种用于超声波检查反应堆压力容器的穿透的方法和装置，特别是穿透的焊接部分。在超声波检查中，能够识别超声波探头相对于被检查部的位置（检查位置），而不受被检查部的表面的影响。超声波检查装置的超声波探头被推压到反应堆压力容器的外表面，并且在改变超声波的入射角的同时，向具有焊接部分的穿透物进行超声波接收超声波。基于通过在穿透的内表面上反射超声波而获得的回波的接收结果，测量相对于反应堆压力容器的壁面的穿透倾角。基于预先计算出的倾斜角度与圆周方向位置的关系来计算穿透的与倾斜角对应的圆周方向位置。然后，作为关于检查位置的信息可以获得圆周方向位置。
