摘　　要：当辐照室发生卡源故障时,辐照物品在特大剂量的照射下,由于能量的积聚,会发生冒烟甚至最终燃烧。介绍了辐照室水喷水灭火系统的研究与设计。通过论述参数选择、喷水灭火系统计算、消防水源、末端试水装置、管材接连接方式以及控制方式等,设计出一套满足国家标准规范要求的辐照室水喷水灭火系统。一旦发生卡源故障,导致辐照物品温度上升,能在辐照室外操作该系统给辐照室内喷水降温灭火。When the radiation source is stuck in the irradiation chamber,the irradiated articles will smoke or even burn finally due to the accumulation of energy under the extremely large dose of irradiation.This paper introduces the research and design of the water spray system in the irradiation chamber.By discussing the parameter selection,water spray calculation,fire water,end water-test equipment,pipe material and pipe connection mode,a set of water spray system for the irradiation chamber that meets the requirements of national codes and standards is designed.In case of a stuck radiation source,which causes the temperature of irradiated articles to rise,the system can be operated outside the irradiation chamber to spray water to cool down and extinguish the fire in the irradiation chamber.
