摘　　要：利用Pyrosim软件模拟某放射性厂房火灾蔓延情况,计算安全出口可用疏散时间。根据人员疏散相关理论分析厂房的疏散条件,在考虑人员分布特点的条件下,通过Pathfinder软件模拟实际场景的疏散过程,并比对分析结果。在分析模拟疏散结果的基础上,找出疏散瓶颈,确认影响疏散的主要因素。结合厂房辐射防护分区情况进一步优化厂房消防疏散设计,最大限度保障火灾事故情况下员工的人身安全,同时可为其他核设施消防设施、通风设施及疏散通道的设计优化提供技术依据。Pyrosim software was used to simulate the fire spread of a radioactive plant and calculate the evacuation time available for the safety exit.The evacuation conditions of the plant were analyzed according to the relevant theories of personnel evacuation.Under the condition of considering the characteristics of personnel distribution,the evacuation process of the actual scene was simulated by Pathfinder software,and the analysis results were compared.On the basis of analyzing the simulated evacuation results,the evacuation bottleneck is found out and the main factors affecting the evacuation are confirmed.The fire evacuation design of the plant is further optimized based on the radiation protection zoning of the plant,so as to maximize the personal safety of employees in the case of fire accidents,and provide technical basis for the design optimization of fire fighting facilities,ventilation facilities and evacuation channels of other nuclear facilities.
