CPR1000机组役前检查异常报告汇总与浅析

对9台二代改进型CPR1000机组役前检查过程开启的异常报告进行汇总，初步分析超标缺陷的数量、类型和产生原因，并按照缺陷类型进一步总结消除缺陷的处理方法，对制造和安装过程质量控制提出提升建议。本文的分析结论为在运CPR1000机组在役检查提供参考，并有助于提升在建CPR1000机组制造及安装质量水平，可为后续核电机组提供借鉴。

This article collects all anomaly report of Pre-service Inspection from 9 CPR1000 nuclear power station, and analyzes the number, type and course of formation of the defects. Furthermore, we summarize the removing method according to the type of defects The conclusion of this article has reference to In-service Inspection and upgrading quality control during manufacture and project processing. And the construction of generation-three nuclear power technology could also use the conclusion above for reference.
