反应堆物理考虑三区栅元的ｘ－ｙ几何中子输运计算徐晓勤根据中子积分输运理论，发展了可以处理三区非均匀栅元的ｘ－ｙ几何多群中子输运问题的数值模型。该模型综合采用了界面流方法和磁撞几率方法的技巧，对于由短形栅元组成的ｘ－ｙ几何组件或堆芯，采用ＤＰ１近似的界... Reactor Physics Considering the x-y Geometrical Neutrino Transport Calculation in Three Regions XU Xiao-Qin According to the theory of neutron integral transport, the numerical value of x-y geometry multi-group neutron transport problem that can handle three-region non-uniform cells is developed model. The model combines the interface flow method and the method of magnetic collision probability method, for the x-y geometric components or cores composed of short cells, using DP1 approximation ...
