核电站堆内构件吊篮筒体的无损检测

Nondestructive testing of RVI Core barrel of Nuclear Power Station

介绍了RCC-M规范下压水堆核电站堆内构件吊篮筒体的无损检测技术,包括液体渗透、射线与超声波检测。同时介绍了各种检测方法应注意的事项,以更好实现吊篮筒体的无损检测,确保焊缝与堆焊层的焊接质量。

Nondestructive testing（NDT）technologies in RCC-M rules for core barrel of reactor vessel internals（RVI）of press water reactor were introduced,including penetrant testing（PT）,radiographic testing（RT）and ultrasonic testing（UT）.The points for attention in NDT were also given to do the NDT of the core barrel perfectly.And ensure obtaining good welding quality of weld and cladding.
