Development of detection technique for fatigue crack due to thermal stratification phenomena in RCS piping

Abstract

Primitive experiment was performed to make thermal fatigue specimen using Argon gas torch as a fundamental work and permanent test-loop for automatic heat-up and cool-down was designed in order to manufacture thermal fatigue specimen. As for the development of detection technique, work was performed to build up a procedure to detect and size fatigue cracks with all currently available ultrasonic testing technique using natural cracked blocks which were made during previous years. Since the final object of this project is to detect fine cracks such as fatigue cracks, one of signal processing techniques which play a great role to improve signal to noise ratio was adopted with the software that was previously developed.
