AP1000核级管道焊缝在役检查分析

The Analysis of the Nuclear Piping Welds In-Service Inspection of AP1 000

该文结合ASME法规要求详细描述了AP1 000核电机组核级管道役前及在役检查的计划安排、检查范围等。阐述了管道役前及在役检查前管道焊缝核查的重要性。实际经验表明,通过采取管道焊缝数据核查、可达性审查以及等轴图编制,可以大大提高役前及在役检查的效率,节省了时间,提高了机组的经济效益。并对AP1 000核电机组核级管道焊缝检查进行了详细地分析。

The paper describe the plans of Pre-service Inspection（PSI）and In-service Inspection（ISI） for AP1 000 nuclear power plant based on ASME. And also describe the use of the non-destructive testing and the scope of ISI. This paper also state the important of the data collection before PSI and ISI, because the perfect data can increase efficiency of the PSI and ISI.Besides, this paper describe the inspection of piping welds in details.
