摘　　要：利用半解析节块法的非线性迭代计算方法求解多维多群中子扩散方程。数值结果表明 ,这种非线性迭代半解析节块法具有较高的精度 ,并且在计算效率上比传统方法有很大的提高。将这种方法应用于SIMULATE E中 ,研制了压水堆燃料管理计算程序CSIM 3B ,对秦山核电厂第一循环进行了跟踪校核计算 。The semi-analytical nodal method with the nonlinear iteration procedure is used for solving the multi-group multi-dimensional neutron diffusion equation.Numerical results show that this method has comparablly high accuracy and improves considerably computational efficiency compared to the conventional nodal methods.The method is embedded into the SIMULATE-E.As a result the code CSIM-3B is developed for PWR fuel management calculation.Following the actual operation history,Qinshan Nuclear Power Plant cycle 1 is calculated using CSIM-3B.The calculated results conform well with the measured value.
