摘要
反应堆压力容器主螺栓作为核设备的重要部件,RSEM标准要求役前及在役阶段对其进行超声波检查。该检测是个多系统配合的过程,它必须依赖专用超声波检查系统、机械扫查器和控制系统的统一协作才能完成。介绍了反应堆压力容器主螺栓超声波检测的部位、探头的选用、仪器的选用以及扫查方式、标定及校核、采集系统和分析系统。
As an important component of nuclear devices, reactor pressure vessel closure studs need to be examined during pre-and in-service inspection according to RSEM. The inspection equipment is a complicated system including mechanical devices, controlling devices and UT inspection devices. This paper focuses on introducing the scope of the reactor pressure vessel closure studs by UT, selection of probes, scanning pattern, and the calibration verification, used equipments, acquisition and analysis system.
