摘　　要：目前在役核电厂中,仪控系统广泛采用模拟设备,但是随着科学技术的发展,数字化安全系统仪控设备逐步应用到新建核电厂,设备鉴定的要求也发生了变化。为适应这一新技术的应用,一些机构进行了相关的技术研究。文章简单概括了这些研究结果,和现行的鉴定标准进行了比对和分析,并就核电厂数字化安全系统仪控设备环境鉴定的措施和方法提出了建议。At present,analog equipment is widely used in the IC system of the nuclear power plants（NPPs）in service.However,with the development of the technology,digital IC equipment for safety system is gradually applied in new NPPs,thus the equipment qualification requirements have to be changed.Some institutes are researching the related requirements to accommodate these new technology applications.This paper briefly summarizes the results of these studies,compares and analyses the existing standards for equipment qualification,and makes suggestions to the environment qualification measures and methods of the digital IC equipment for safety system.
