摘要
本厂两台机组各进行一次调试期间的初始水压试验和大修期间的重复水压试验,一回路主系统的全部承压部件在初始水压试验时承受22.8 MPa的水压,在重复水压试验时承受20.6 MPa。本文在总结1、2号机组四次水压试验实践的基础上,介绍了RCC-M和RSEM规范对水压试验的要求、试验的实施过程与主要结果等,总结了初始水压试验与重复水压试验的不同点以及试验的风险、注意事项与实践经验,对同类型压水堆有很好的借鉴作用。
Initial hydraulic test during commissioning and test renewal during refueling outage were performed once for unit 1 and 2 of Qinshan Ⅱ respectively, all safety class 1 pressure-retaining components were subjected to 22.8 MPa in initial hydraulic test and 20.6 MPa in test renewal. Based on the practice of the four times successful hydraulic test of the main primary system for Qinshan Ⅱ , the RCC-M and RSEM requirements related, brief test process and main results etc were introduced, and the differences between initial test and test renewal, as well as the risks, precautions and practical experience were summed up. They will be beneficial for the same kind PWR nuclear power plants.
