• 論文の詳細を見る

• In this research, a laser ultrasound technique (LUT) is reported for nondestructive characterization of hydride rims (HR) in Zircaloy cladding tubes. With the LUT, guided waves propagating in the Zircaloy tubes with different HR thickness are generated and detected remotely by optical means. By measuring the dispersive ultrasonic wavespeeds with the LUT, combining with the inversion technique, relations between the dispersion relations and thickness of HR are established. Good accuracy in measuring the HR thickness is demonstrated with this combined LUT with inversion algorism technique.
