摘　　要：核电厂很多设备或管道存在腐蚀检查不可达区域,存在一定的安全隐患。本文,针对小型容器(内部)、小支管两种工况,即中型管道转弯处附近内部状况,开发了一套智能诊断装备,能实现对中型管道转弯处的内部检查,保证核电厂工作人员及时掌握该不可达部位的腐蚀状态,避免安全事件发生。There are unreachable areas for inspection of many equipment or pipelines in nuclear power plants,which have certain potential safety hazards.In this paper,aiming at the two working conditions of small container(internal)and small branch pipe,that is,the internal condition near the turning of mediumsized pipeline,a set of intelligent diagnosis equipment is developed,which can realize the internal inspection of the turning of medium-sized pipeline,ensure that the staff of nuclear power plant can grasp the corrosion state of the unreachable part in time,and avoid safety events.
