Abstract

Abstract

The reliability of in-service inspection was calculated and analyzed based on the probability model and ultrasonic testing numerical model.The POD curve and its 95% lower bound of different defects in girth weld of RPV were calculated.The result indicated that the reliability analysis could give a quantitative evaluation for in-service inspection.
