摘　　要：反应堆在事故情况下的氢气风险一直是反应堆安全研究中非常重要的内容。利用氢气风险管理程序GASFLOW计算了反应堆一回路破口事故后安全壳内的氢气分布,对计算结果进行分析。在GASFLOW计算结果的基础上,应用COM3D程序模拟氢气燃烧和爆炸,研究了氢气浓度以及点火位置对火焰扩散的影响。The risk of hydrogen combustion and detonation is always one of the most important nuclear safety issues. In this paper, the hydrogen transport and distribution in the containment is simulated with GASFLOW code when a LOCA accident happened. Then by coupling the GASFLOW data to COM3D which is developed by. KIT to simulate the hydrogen combustion and detonation, the pressure and temperature development in the containment with different combustion locations is analyzed.
