摘要：核安全法規(guī)HAF003中明確指出關(guān)于核電廠安全級物項“必須對保證質(zhì)量所必需的每一個工作步驟都進行檢查。如果不能對已加工的物項進行檢查或要求附加的工藝監(jiān)視，大綱必須規(guī)定間接控制措施”，以保證核電廠安全級物項能夠長期安全、可靠、穩(wěn)定運行。本文主要描述了多種檢驗方法在核電廠安全級DCS設(shè)備盤柜裝配檢查中的應(yīng)用，通過對標準RCC-E“MC2000目視檢查和機械檢查”要求的詳細解讀和對安全級DCS設(shè)備盤柜工程設(shè)計應(yīng)用特點分析，結(jié)合安全級DCS設(shè)備盤柜裝配操作工藝流程，明確提出了多種檢驗方法：涂抹標記法、指差呼稱法、扭矩校驗法、隔離驗證法和光源照射驗證法在安全級DCS設(shè)備盤柜裝配檢查中的應(yīng)用過程。這些檢驗方法已在多個核電機組安全級DCS設(shè)備盤柜裝配檢查中得以應(yīng)用，證明了應(yīng)用多種檢驗方法可有效提高DCS設(shè)備盤柜裝配質(zhì)量，能及時發(fā)現(xiàn)人因操作失誤產(chǎn)生的質(zhì)量不良問題，并得以糾正處理，保證了安全級DCS設(shè)備盤柜裝配質(zhì)量符合工程設(shè)計圖紙和相關(guān)法規(guī)標準要求。

Abstract: In the nuclear safety regulation HAF003, it is clearly pointed out that the safety level items of nuclear power plant "must be checked for every work step necessary to ensure the quality".If the processed items cannot be inspected or additional process monitoring is required, indirect control measures must be specified in the outline to ensure the long-term safe, reliable and stable operation of safety level items of nuclear power plant. This paper mainly describes the application of various inspection methods in the assembly inspection of safety grade DCS equipment cabinets in nuclear power plants. Through detailed study of the requirements of standard RCC-E “MC2000 visual inspection and mechanical inspection”and analysis of application characteristics of safety grade DCS equipment panel engineering design,combined with safety level DCS equipment cabinet assembly operation process, a variety of inspection methods have been clearly proposed: the application process of the smear marking method, the finger confirmation method, the torque verification method, the isolation verification method and the light source illumination verification in the assembly inspection of the safety level DCS equipment. These inspection methods have been applied in the assembly inspection of safety level DCS equipmentcabinets of several nuclear power plants. It has been proved that the application of multiple inspection methods can effectively improve the assembly quality of DCS equipment cabinets, timely detect the quality problems caused by human error, and be corrected and ensured that the assembly quality of the safety level DCS equipment cabinet assembly meets the design drawings and relevant regulatory standards.
