Onward development of nondestructive testing methods for inservice inspection of reactor power plants
Description
The studies so far centered on hardware and software developments to improve ultrasonic detection and analysis. The state of the art of an ultrasonic probe with variable acoustic field parameters and control device, of reflector detection from the transit time, and of probe stability is reviewed in particular. With the present active probes for thick welds (vibrating material, vibration damping), reliable stability control on the basis of pulse monitoring cannot be ensured. (DG)

Die durchgefuehrten Arbeiten behandeln die Hard- und Software-Entwicklungen zur Verbesserung von Ultraschall-Such-und-Analyse-Verfahren. Insbesondere wird der neueste Stand eines Ultraschall-Pruefkopfes mit variablen Schallfeldparametern und zugehoerigem Steuergeraet, der Reflektorortung aus der Laufzeit und der Pruefkopf-Stabilitaet beschrieben. Beim derzeitigen Aufbau der aktiven Dickschweissnaht-Pruefkoepfe (Schwingermaterial, Bedaempfung) kann eine zuverlaessige Stabilitaetskontrolle mit Hilfe der Sendeimpulsueberwachung nicht gewaehrleistet werden.
