摘要

我国在建和已建核电厂大都位于沿海，服役大气环境大都属于典型的海洋性大气环境，腐蚀性较强。核电项目设备和材料的腐蚀一直是在建和运行核电厂重点关注的问题，关系核电项目的经济性和安全性。尤其核电行业并没有针对暴露在室外大气环境下的设备防腐蚀问题专用的防腐蚀标准。对比了核电项目现行防腐蚀工作措施与防腐蚀行业的通用标准要求，以发黑和磷化处理为例分析了其作为核电紧固件临时性防腐蚀措施的效果及不足，寻找差距并提出了建议和改进措施，为核电项目防腐蚀工作提供了参考。

Abstract

The nuclear power plants under construction and operation in China are all located in the coastal area, and the atmospheric environment mostly belongs to the typical marine atmospheric environment with high corrosiveness.Corrosion of equipment and materials in nuclear power projects has always been a key concern of nuclear power plants under construction and operation, which is related to the economy and safety of nuclear power projects.In particular, there is no special anti-corrosion standard for equipment exposed to outdoor atmospheric enviroment in nuclear power industry.In this paper, the current anti-corrosion measures of nuclear power projects with the general standards of anti-corrosion industry were compared.Taking blackening and phosphating treatment as examples, the effects and shortcomings of the temporary anti-corrosion measures for nuclear power fasteners were analyzed, the gap was found out, and the suggestions and the improvement measures were puts forward, which could provide a reference for the anti-corrosion work of nuclear power projects.

Key words： nuclear power; atmospheric corrosion environment classification; coating; blackening; phosphating
