In 1998, NEL developed X-probe in cooperation with foreign firms. Recently NEL has developed the transmit-receive type array probe characterized with a significantly improved resolution for circumferential cracks. Th e advanced probe, called Smart Array Probe, has been developed based on the result of detailed numerical simulation. The doubled channels in the circumferential mode have greatly improved the circumferential resoluti on of Smart Array Probe. With all the circumferential mode channels on the sa...

This paper describes the result of demonstration test using WesDyne International's inspection system in terms of its sizing capability of crack from the inner diameter (ID) of PWR RV head penetrations, detectability of the crack e mbedded under repair welding, which was applied for isolation from the primary water environment, and the propagation of ultrasonic wave from the ID penetration to the inside of J-weld. The result of the laboratory tests have demon strated the sizing capabilities of both ultraso...
