摘要
火灾概率安全评价(PSA)是评估核电厂风险并发现薄弱环节的有效工具,详细的火灾情景分析是其中一个重要环节。在火灾概率安全评价的火灾隔间定量筛选的过程中,火灾隔间的分析通常较为保守,为使结果更贴近核电厂实际,有必要对风险重要的火灾隔间进行详细的火灾情景分析。通过确定特定的火灾情景,分析火灾的发展蔓延并评估火灾情景的发生频率,从而为最终的火灾风险定量化提供基础。本文探讨了详细火灾情景分析在火灾概率安全评价中的应用,并以单一火灾隔间为例阐述分析方法,为核电厂火灾概率安全评价工作提供支持和参考。
Fire PSA is the effective tool for assessing the risk of nuclear power plant and finding the weakness. Fire scenario analysis is an important tache in fire PSA.The analysis of fire compartment is usually conservative during quantitative screening process, in order to make the results more actual, it is necessary to analyze fire scenario of the fire compartment which risk important. Determining the specific fire scenario, analysising fire spread and evaluating the occurrence frequency of fire scenario, provides the basis for the fi- nal quantitative fire risk. This paper discusses the fire scenario analysis application in fire PSA, and introduce the method of fire scenario for single fire compartment, then to provide support for fire PSA in nuclear power plant.
