摘要
反应堆冷却剂泵飞轮键槽是易损部位,要求役前及在役检查阶段对其进行超声波检查。重点介绍了反应堆冷却剂泵飞轮检测的范围,以及一种组合式探头的设计应用、检查实施、信号分析等。该超声波技术符合规程要求。提出一种新的针对主泵飞轮的超声波检查方式,该检查方式具有更高的检查灵敏度。
The reactor coolant pump flywheel keyway is a vulnerable part. Therefore, it requires an ultrasonic inspection both pre-service and in-service. This paper focuses on the scope of the inspection and the design of a combined probe which can do the inspection and the signal analysis. It is confirmed that the ultrasonic inspection method meets the requirements of the standards. It also provides a new method of ultrasonic inspection with higher sensitivity.
