放射性气体的安全性问题是涉及反应堆运行中必需研究的重要问题.因此在钚气溶胶环境中,对钚材料裂变产生的放射性气体裂变产物,需要研究其在钚气溶胶环境中的迁移过程.对放射性惰性气体Kr87,Kr88的实验测量数据进行了具体分析.依据它们具有钚材料直接裂变和作为固体裂变产物子体两种来源这一物理特性,在不同的制样时间对Kr87/Kr88比值变化规律进行分析.确立了这两种来源的在钚气溶胶环境中的物理图像和迁移过程的物理模型,并与实验数据进行比较以验证模型的正确性.

It is a key aspect to study security of radioactivity gas in reactor circulation. It is necessary to study the transport process of radioactivity inert gases krypton in plutonium aerosol environment after fission occurrence. The experimental data of Kr87 and Kr88 were analyzed. According to the physical propertics of the two different sources,Kr87/Kr88 ratio variety law was analyzed at different sampling times. The physiced picture and model of transport process in plutonium aerosol environment were established by comparing with experimental data.-
