摘要
讨论了判断持续裂变链引发的理论依据,利用基于Geant4toolkit开发的蒙特卡罗直接模拟程序,计算了一系列测试几何和超瞬发临界5c/的GodivaⅠ反应堆内持续裂变链的引发概率。结果表明,蒙特卡罗直接模拟计算的结果与Mercury程序及确定性理论结果均一致。
The criterion for persistent fission chain determination was discussed and the analog Monte-Carlo code for calculating initiation probability of persistent fission chain based on Geant4 toolkit was developed.Initiation probabilities for a suit of test problems and GodivaⅠ reactor whose reactivity is 5 above prompt critical were calculated using the code.Calculated results are consistent with those obtained from Mercury code and the deterministic prediction.
