核电站焊缝渗透检测验收标准差异

Comparison of Acceptance Standards for Liquid Penetration Examination in Nuclear Power Stations

摘要: 对CPR1000与AP1000等核电站中核岛与常规岛焊缝渗透检测的验收标准进行了分析;比较了RCC-M《压水准核岛机械设备设计和建造规则》、ASME(美国机械工程学会)BPVC《锅炉及压力容器规范》及JB/T 4730.5《承压设备无损检测渗透检测》三个标准记录阈值与圆形缺陷显示评定等方面的差异,便于检测人员正确区分和使用.

Abstract: Acceptance standards for liquid penetration examination in the nuclear islands and conventional islands of the CPR1000 and AP1000 nuclear power stations were compared.The differences in recording threshold and circular indications assessment etc.of RCC-M,ASME and JB/T 4730 were analyzed.
