摘要
以核电厂人员可靠性分析中的全局决策树方法及其应用研究为主要内容。重点介绍全局决策树方法的基本框架、背景和实施步骤。结合秦山二期核电厂的人员可靠性现场访谈形成影响因子和品质等级描述,并以SLOCA和SGTR为例进行全局决策树方法分析。该方法以图形化决策树的形式,综合考虑了各个影响因子对人误概率的影响。分析表明该方法能够适应人误分析过程中出现的不确定性,具有较高的可靠性和实用性。
The paper introduces a human reliability analysis method mainly used in Nuclear Power Plant Safety Assessment and the Holistic Decision Tree （HDT） method and how to apply it. The focus is primarily on providing the basic framework and some background of HDT method and steps to perform it. Influence factors and quality descriptors are formed by the interview with operators in Qinshan Nuclear Power Plant and HDT analysis performed for SGTR and SLOCA based on this information. The HDT model can use a graphic tree structure to indicate that error rate is a function of influence factors. HDT method is capable of dealing with the uncertainty in HRA, and it is reliable and practical.
