摘　　要：通过应用火灾动力学软件FDS,建立了一套核电厂主储油罐间防火阎响应与失效两种状态下的对比模型,讨论了烟气形态、火焰形态、火源热释放速率及火灾温度场随时间的变化规律。研究表明,防火阀对于核电厂主储油罐间火灾事故的控制效果非常明显,通过火灾封锁法能够有效控制火源热释放速率,降低环境温度,体现了FDS应用在核电厂火灾预防方面的优势。In this paper, a model simulating real fire scenario was established by FDS to compare the two modes of fuel tank room in nuclear power plant between the dampers response and failure. It is discussed the smoke shape, flame shape, heat release rate and the fire temperature field variation with time of the two modes. Studies have shown that the fire control damper is obviously effective to control the fire heat re- lease rate, the way of fire blocking can control the heat release rate and the ambient temperature. There- fore, it presents the advantage of FDS in nuclear power plant.
