      EPR与CPR1000核电厂1级部件制造与安装水压试验差异研究

      Research on the Differences of Hydrostatic Test for Class 1 Components of EPR and CPR1000 Nuclear Power Plants in the Phases of Manufacturing and Installations

      摘要:
      1级部件制造与安装阶段的水压试验是核电机组后续调试与安全运行的重要前提.对比分析了不同版本法国《压水堆核岛机械设备设计和建造规则》(RCC-M)关于水压试验要求的差异,并结合CPR 1000和EPR 2种机组的系统和结构特点,对1级部件在制造、安装阶段水压试验的试验压力和试验边界等差异进行了论述,并探讨了EPR机组1级部件在制造与安装阶段水压试验的压力选取方法,所得结果可为EPR机组制造与安装阶段的水压试验工作提供重要参考.
      Abstract:
      The hydrostatic test for Class 1 components in the phases of manufacturing and installations is a critical pre-requirement for subsequent commissioning and secure operations.The discrepancies of the requirements for hydrostatic testing are compared and analyzed between the different versions of French standard of Design and Construction Rules for Mechanical Components of PWR Nuclear Islands (RCC-M).Taking account of the characteristics of the system and structure of CPR1000 and EPR reactors,the differences of test pressure and test boundaries of hydrostatic test for Class 1 components in the manufacture and the installation phases are presented.The method on how to select test pressure for EPR Class 1 components in the manufacture and the installation phases is also explored and discussed.The conclusions can provide important reference for hydrostatic tests for EPR reactors.
