摘　　要：Monte-Carlo方法是核临界计算的有效手段之一,应用该方法对水淹条件下多块材料球壳增殖系统的临界状态进行了计算分析。结果表明:当水的深度d≤15 cm时,水淹围包对该系统的临界状态有着非常显著的影响,当水的深度d>15 cm时,系统的临界值基本为一常数;另外,当水淹进入系统,使内部空体完全充水时,对系统临界状态影响要比未进水影响大。A Monte-Carlo method is one of the effective measures in nuclear critical security analysis. It was used to study the critical variation about breeder system of multi-region spherical shell in the case of water submergence. The results show that the water submergence has a very distinct influence on the critical value Keff under water submergence depth d≤15 cm, at d 〉15 cm, Keff is essentially a constant.
