核电厂传统人员可靠性分析方法中引入班组因素的研究

在核电厂等大型复杂系统中，人员干预行为通常以班组的协作来完成，而目前核电厂概率安全评价（PSA）采用的以人的失误率预测技术（THERP）和人的认知可靠性（HCR）方法为代表的人员可靠性分析（HRA）方法主要关注对个人绩效的影响，它们在评估核电厂主控室班组绩效时存在一定局限。本文定义一种新的绩效形成因子“班组绩效形成因子（TPSF）”，并将其合理地引入THERP和HCR方法的定量化体系中，使它们可在一定程度上体现班组环境对人员绩效的影响。文章提出了TPSF等级的评价方法及将其引入THERP和HCR方法的定性实施框架。结果证明，合理地将班组因素引入传统HRA方法能改进它们对班组环境下人员绩效模化的合理性。

Integrating Team Factor Into Current Human Reliability Analysis of Nuclear Power Plant

In large complex systems such as nuclear power plants(NPPs),most people work in teams or groups.However,the current human reliability analysis(HRA) methods used in probability safety assessment(PSA)of NPPs are generally focused on the assessment of individual performance.The technique for human error rate prediction(THERP)and human cognitive reliability(HCR)are the most widely used human reliability analysis methods.Therefore,the limitations will exist consequentially when we use the current HRA methods to ...
