从安全观点来看,与动力堆比较,实验堆参数低、装料少、结构和运行简单,一般认为它的安全性好。但实验堆亦有不安全特征,堆芯多变、启停频繁、操作过程多、试验样品与堆芯混成一体等,这些都易引发严重事故。实验堆放射性元素贮存量少,事故后果较轻,但实验堆,特别是游泳池堆仅有一道屏障,一旦堆芯熔化,裂变产物可能直接释放到周围环境,所造成的危害究竟如何?这正是本工作要探讨的问题。我们用概率论

From a safety point of view, compared with the power reactor, the experimental reactor parameters low, less loading, the structure and operation is simple, it is generally considered to be safe. However, there are also unsafe characteristics of the experimental reactor, changing the core, starting and stopping frequently, the operation process, the test sample and the core mixed into one, which are likely to lead to serious accidents. There is only a small amount of radioactive elements stored in the experimental reactor and the aftermath of the accident is light, but there is only one barrier in the experimental reactor, especially in the pool. Once the core has melted, the fission products may be directly released to the surrounding environment. This work to explore the issue. We use probability theory
