介绍三维多群中子输运 燃耗耦合P3近似蒙特卡罗程序MCMG BURN .该程序是在连续截面蒙特卡罗程序MCNP和反应堆栅元均匀化程序WIMS基础上发展而来的 .使用多群截面库模拟临界实验堆和高通量工程实验堆 ,取得了与MCNP和实验一致的结果 .MCMG BURN具有与MCNP相同的精度 ,但计算时间较MCNP要少得多 .
This paper introduces the MCMG BURN, a three-dimensional multi-group neutron transport fuel-burnup coupled P3 Monte Carlo program, which is developed on the basis of continuous-section Monte Carlo MCNP and reactor cell homogenization WIMS program. The results of MCNP and experiments are consistent with those of MCNP and MCNP.MCMG BURN has the same accuracy as MCNP but its calculation time is much less than that of MCNP.
