通过对以往发布的核电厂设施设备防护涂层相关标准分析.结合核电厂应用实际,确定将涂层分级的内容修改为按涂层使用区域分类作为标准编制的基础。同时根据标准各部分主要技术内容的引用和接口给出了防护涂层标准的结构设置,阐述了标准制修订过程中重要的技术内容变化和尚需进一步完善的地方,最后根据与美国核电防护涂层标准之间的差距提出了后续应关注的标准化建议。 Based on the analysis of the standards of the protective coatings for nuclear power plant facilities and equipment released in the past, the contents of the classification of coatings were revised to be the basis for the preparation of standards according to the classification of coating use areas. At the same time, according to the references and interfaces of the main technical contents of each part of the standard, the structural setting of the protective coating standard is given, and the important technical content changes and the need to be further perfected in the standard revision process are elaborated. Finally, The differences between the layers of standards raise the standardization recommendations that follow.
