摘要
目前秦山核电厂正在推进300 MWe机组运行许可证延续项目。依据国家核安全局的技术政策要求,必须先建立维修有效性评价体系(即维修规则)。鉴于此,秦山核电厂于2017年开展了维修规则试点研究工作。以海水循环水系统为例,介绍了核电厂非安全重要且运行系统的维修规则开发流程,为同行电厂开展相关工作提供参考。
At present,the Qin-Shan Nuclear Power Plant(NPP)is promoting the Operating Licenses Extension(OLE)project.It is necessary to establish a Maintenance Rule(MR)System according to the requirements of the National Nuclear Safety Administration.So the Qin-Shan NPP carried out a pilot study for MR in 2017.Take BXHS system in Qin-Shan NPP as an example and details the process of maintenance rule development for the non-safety-significant and normal operation systems in NPP for other NPPs’reference on related works.
