摘　　要：核电厂主控室一旦发生火灾,可能会危及操纵员安全,从而影响对核电厂运行和安全停堆的控制,引起堆芯损伤的潜在风险。利用FDS火灾动力学软件建立核电厂主控室火灾发生发展的模型,通过设定不同的火灾情境,分析主控室火灾场景中关键参数随时间的变化,并计算得出主控室关键火源的热释放速率和操纵员及时撤离主控室的时间,从而验证了FDS软件在核电厂火灾应用方面的可行性和优势。Research of fire is an important subject in the field of nuclear fire protection and safety. In case of fire in the main control room of a nuclear power plant, the operator may be jeopardized and thus the control of nuclear power plant operation and safety shutdown will be affected, which leads to the potential risk of the core damage. By applying the fire dynamic software Fire Dynamics Simulator （FDS）, this paper establishes the model of fire oc- currence and development in the main control room of nuclear power plants. Through setting several fire scenarios, the paper analyzes the changes of key parameters over time and calculates the heat release rate of the key fire source in the main control room and the time of the operator evacuating from the main control room, verifying the feasibil- ity and the superiority of FDS software application in nuclear power plant fire.
