Dry ultrasonic testing of reactor components by EMUS. Potential, sensivity for detection, conception of an inspection scheme
Abstract
It has been shown that on principle a dry ultrasonic inspection of thickwalled primary circuit components of nuclear power plants is possible using EMUS-probes. Investigations on test specimens have demonstrated that the inspection area sprescribed by regulations can be covered by SH-waves and the postulated sensitivity of detection for cracklike defects can be reached.
