A Monte Carlo study of the Feynman-method with a simple code simulating the multiplication chain, confined to pertinent time-dependent phenomena has been done. The significance of its key parameters (detector efficiency and dead time, k-source and spallation neutrons multiplicities, required number of fissions etc.) has been discussed. It has been demonstrated that this method can be insensitive to properties of the zones surrounding the core, whereas is strongly affected by the detector dead time. In turn, the influence of harmonics in the neutron field and of the dispersion of spallation neutrons has proven much less pronounced.
已经进行了一项蒙特卡罗研究，使用一个简单的代码来模拟增殖链的费曼方法，该方法仅限于相关的时间相关现象。讨论了其关键参数（探测器效率和死时间、k源和散裂中子多重性、所需裂变数等）的重要性。结果表明，该方法对堆芯周围区域的特性不敏感，而受探测器死时间的影响很大。反过来，中子场中谐波和散裂中子散射的影响则要小得多。
