摘要
文章应用S_n方法对U^(235),Pu^(239)的裸球和U^(235),Pu^(230),U^(238)构成的组合球的临界情况,如临界半径、临界质量、中子注量分布和泄漏的中子流进行了计算。此外,还研究了加浓度、压缩比、惰层厚度对临界的影响。所得的结果与已发表的实验数据甚为吻合。
In the paper, with S_n method We calculated the numerical value of criticalcondition,critical radius and masses, flux distribution and neutron current densityof leakage for bare sphere and combined sphere of U^(235), Pu^(239) and U^(239). In addi-tion, We also studied the effects of parameter change, for instance, concentration.compressibility, and thickness of inert layer. The main results obtained are inagreement with the published experiment data.
