Propagation mode analysis of long-range guided ultrasonic wave and application to inspection of PHWR feeder pipe

Creators

Description

Because of recent leakage of coolant due to cracks in feeder pipe, non-destructive inspection is required. However, because of limited accessibility due to the complex shape and high radiation, it is not easy to apply the conventional ultrasonic method. In order to develope a long-range guided ultrasonic method, methodology for the dispersion curve and wave structure are described. Based on the review of the dispersion curves and wave structures in the feeder pipe, L(0,4) mode for detection of circumferential cracks, F(1,6)-F(4,6) or F(1,7)-F(4,7) modes for detection of axial cracks, were recommended
