火灾情景下的人员可靠性分析

国内外各核电厂火灾概率安全评价（PSA）表明，人员操作对火灾情景下的电厂风险有重要影响，因此，有必要采用系统的人员可靠性分析（HRA）方法来评价火灾情景下的人员失误概率。本文阐述了HCR/ORE和CBDTM模型的基本理论和在火灾情景下的特殊考虑。将HCR/ORE和CBDTM方法与THERP方法相结合应用于火灾情景下的人员可靠性分析，并进行了实例分析。为建立更符合工程实际的火灾PSA模型奠定了基础。

Human Reliability Analysis Under Fire Condition

It is identified in the fire probabilistic safety assessment (PSA) of nuclear power plants that human action has important effect on the risk of plant under fire condition. So it’s necessary to assess human error probability under fire condition by the systemic methodology. The HCR/ORE and CBDTM models and specific considerations under fire condition were described in this paper. The combination of HCR/ORE, CBDTM and THERP was applied to human reliability analysis (HRA) under fire condition with an example given for demonstration. The basement of setting up the more practical fire PSA models for engineering is established.
