Automated Extraction Automated reporting function Digital UT data Ultrasonic Testing
In domestic nuclear power plants, ultrasonic testing is performed as an in-service inspection for piping accor ding to JSME code. Using automated UT equipments and UT analysis system, confirmation of repeatability for UT data, automated extraction and detailed evaluation are performed. Furthermore, automated reporting function ma kes reduction of hours of work. In this report, the outline and advantage of UT analysis system are described....

The probe to be applied for the inner surface of the CRDM tubing having a narrow portion of the reactor vessel, however existing probe is not applicable to the minimum gap 1.5 mm of the CRDM tubing. It is necessary to study further thinning of the probe while maintaining sufficient detectability and flaw direction discrimination. Therefore, a new coil system using pancake coils was developed. As a result of a verification test, it was confirmed that an EDM flaw of 0.2 mm in length, 0.2 mm in width and 0.2 m...

Automatic flaw detection machine Maintenance heritage Reactor vessel Ultrasonic testing
As "A historic heritage related to maintenance technology and a cultural heritage of humankind with the aim of encouraging the development, dissemination and contribution to society of Maintenology." the automatic ultrasonic flaw detection machine for reactor vessel (A-UT Machine) was recognized as the first heritage.
The A-UT machine was used for the first time in the world for the inspection of reactor vessels of PWR nuclear power plants in 1995. Since then, improvements have been made to improve the accu...

calibration high temperature sound velocity thickness measurement Thin-film UT sensor
In this study, in order to propose a calibration method using a correction formula for each steel grade obtained in advance as a calibration method for plate thickness measurement using a permanent UT sensor such as MHI’s Thin-film UT sensor, a temperature-sound velocity correction formula for each steel grade was calculated by obtaining sound velocity values for each temperature from ordinary temperature to 200 degrees centigrade using the Thin-film UT sensor and multiple specimens of steel grade. Using th...
