本文介绍了一种估算铀水系统(或铀与其它含氢介质的均匀混合系统)的“安全质量”,即不会产生临界安全事故的U~(235)质量的简易方法.在这个方法中,利用了带全水反射层的球形铀水系统的最小临界质量的实验数据和最佳的N_H/N_5比值.估算中采用了反应堆理论的单群模型.文末简略地讨论了方法的可靠程度,并就两个例子说明了方法的应用.
This article presents a “safety quality” of uranium water systems (or homogeneous mixing of uranium with other hydrogen-containing media), a simple method of U 235 mass that does not produce a critical safety hazard. In this method , The experimental data of the minimum critical mass of spherical uranium water system with full water reflection layer and the best ratio of N_H / N_5 were used.The single-group model of reactor theory was used in the estimation.The reliability of the method was briefly discussed, Two examples are given to illustrate the application of the method.
