| 摘 要： | 采用根本原因分析法(RCA),应用故障模式分析矩阵,对大亚湾核电站RRI/SEC热交换器频繁出现压差高这一故障的原因进行了分析,并通过试验验证,最后确定了RRI/SEC热交换器故障的根本原因。采用修改SEC系统的加药方式,很好地解决了故障问题。经过两年的运行验证,曾出现压差高的8台热交换器运行状况良好,压差值已控制在设计范围内。 |

| Abstract: | This paper have analyzed the reason of high pressure difference of RRI/SEC heat exchanger inDaya Bay nuclear power station,by adopting the Root Cause Analysis method(RCA) and the analysis matrixof failure mode.After few experiments have been done on the SEC system,we confirm the reason of theexchanger failure.Through modifying the method of adding chemicals to SEC system,the exchanger failureis solved satisfactorily.Two years of operation indicate that the 8 exchangers ever with failure can operatesatisfactorily,and the pressure difference is in the normal range. |
