AP1000核电站中一体化堆顶组件(IHP)排风管在受限拼装与焊接条件下,针对弯头对接焊缝,依据射线检测原理,制定射线检测工艺,阐述了受限条件下射线检测过程难点的解决与试验方法,同时依据试验检测结果,对检测技术进行分析与评价。 Under the confined assembly and welding conditions, the IH1000 exhaust pipe of the AP1000 nuclear power station is aimed at the elbow butt weld, and the radiation detection technology is formulated according to the principle of radiation detection. The difficulties of the radiation detection process under limited conditions are described Solution and test method, at the same time based on the test results, the detection technology analysis and evaluation.
