Description

Validation of ultrasonic testing (UT) for detecting stress corrosion cracks (SCCs) in the Pressurizer's dissimilar metal weld of nuclear power plant, PWR, was carried out. Appropriate UT methods using probes consist of separate transmit and receive piezo-electric elements with longitudinal wave can detect both axial and circumferential SCCs ranged from 12% to 23% thickness of weld.
