 摘要：隨著我國核電事業的不斷發展，核能發電已被人們廣泛接受。截 至目前，我國在役運行機組已達到47臺。隨著機組運行時間的積累，核 電數字化儀控系統設備、部件存在不同程度的故障和性能降低等老化問 題，急需對原始物項進行替代。然而，國內無論是監管層面還是行業層 面，目前均沒有形成一個統一的方法解決在役運行核電廠（NPP）數字 化儀控產品的物項替代問題。針對這一情況，本文結合國內核電廠數字 化儀控系統物項替代的實際應用，對我國能源行業標準及美國EPRI相關 的導則、標準進行了研究，提出適合國內核電行業應用的一種物項替代 方法，對國內核電行業物項替代活動具有很好的借鑒意義。

關鍵詞：核電廠；數字化儀控系統；物項替代

Abstract: With the development of China's nuclear power industry,  nuclear power generation has been widely accepted. Up to now, the  number of units in-service has reached 47. With the accumulation of  unit running time, the equipment and components of nuclear power  digital instrument and control system have aging problems of different  degrees, such as failure and performance degradation, so it is urgent to  replace the primary items. However, both at the regulatory level and the  industry level in China, there is no currently a unified method to solve  the problem of item substitution of digital instrument control products  for in-service nuclear power plant (NPP). In order to solve this situation,  combined with the domestic nuclear power plant item substitution  of the actual application of DCS instrument control system, this  paper studies the criteria of energy industry in China and the related  guidelines, standards of EPRI in America, and proposes an approach of  item substitution for China's nuclear industry application, which has  the very good reference to item substitution activity for China's nuclear  industry.

 Key words: Nuclear power plant; Digital instrument and control system;  Item substitution
