基于核电冷源安全的海洋生物调查及筛选评价方法研究

Study on the method of marine organisms investigation,screening and evaluation based on nuclear power plant cold source safety

我国滨海核电项目已发生多起海洋生物暴发导致取水系统异常的事件。当前核电厂建设前期海洋生物调查与评价缺乏对致灾海洋生物的针对性。本文结合国内外已开展的致灾海洋生物与核电厂冷源安全的现场工作反馈,分析了现有核电项目建设前期海洋生物调查工作的不足,提出了调查方案的优化措施,以尝试增强海洋生物调查、筛选评价与核电厂冷源安全纵深防御体系的关联。

There have been a number of marine biological outbreaks in coastal nuclear power projects in China,which lead to exception of water intake system of nuclear power plants.Nuclear plants carry out marine ecological investigation at the feasibility study stage.At present,the investigation and evaluation of marine organisms in the early stage of nuclear power plant construction are lack of pertinence to the marine organisms causing disasters.In this paper,the actual work feedback of disaster causing marine organisms and nuclear power plant cold source safety has been combined.The deficiencies of marine biological investigation in the early stage of nuclear power project construction are analyzed and the optimization measures of investigation scheme are provided.To try to enhance the relationship between marine biological investigation and the defense system of NPP’s cold source safety in depth.
