基于ISM的海上浮动核电站失水事故影响因素分析

Analysis of Influencing Factors of Loss of Coolant Accident in Offshore Floating Nuclear Power Plant Based on ISM

为保障海上浮动核电站安全运行,文章以海上浮动核电站失水事故为研究对象,采用文献研究的方法从个体、设备、环境、管理4个维度提取13个影响失水事故的因素,运用解释结构模型(ISM)的方法分析13个因素的层次关系,结果表明:员工心理状态、员工生理状态、管路状况和电磁排放控制线路状况为影响失水事故的直接因素,法律法规为底层因素,其余因素为中间层因素,针对模型结果,提出了浮动核电站失水事故相关预防措施,研究结果可为浮动核电站的设计和应急管理提供参考。

In order to ensure the safe operation of offshore floating nuclear power plants,this paper takes the loss of coolant accidents in offshore floating nuclear power plant as the research object,uses the method of literature research to extract 13 factors affecting the loss of coolant accidents from the four dimensions of individual,equipment,environment,and management and analyzes the hierarchical relationship of 13 factors using the Interpretive Structure Model(ISM)method.The results show that the psychological state of employees,the physiological state of the employees,the pipeline conditions and the electromagnetic emission control line conditions are the factors that directly affect the loss of water accidents,laws and regulations are the bottom factors,and the rest are middle-level factors.Based on the model results,relevant suggestions are made for the prevention of loss of coolant accident in floating nuclear power plants.The research results can provide references for the design and emergency management of floating nuclear power plants.
