 摘要：随着我国核电事业的不断发展，核能发电已被人们广泛接受。截 至目前，我国在役运行机组已达到47台。随着机组运行时间的积累，核 电数字化仪控系统设备、部件存在不同程度的故障和性能降低等老化问 题，急需对原始物项进行替代。然而，国内无论是监管层面还是行业层 面，目前均没有形成一个统一的方法解决在役运行核电厂（NPP）数字 化仪控产品的物项替代问题。针对这一情况，本文结合国内核电厂数字 化仪控系统物项替代的实际应用，对我国能源行业标准及美国EPRI相关 的导则、标准进行了研究，提出适合国内核电行业应用的一种物项替代 方法，对国内核电行业物项替代活动具有很好的借鉴意义。

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
