摘要
以精度高、速度快的二、三维非线性迭代先进节块法扩散计算程序 NLNEM和节块精细功率重构程序 3DPPREC为基础，参照 SIMULATE的功能研制了具有多种热工反馈功能的三维压水堆燃料管理程序 CSIM- 3。用该程序对秦山核电厂第 1、 2循环进行跟踪计算。结果表明，功率及燃耗分布相对误差小于 5％，除个别测量点上临界硼浓度计算值与测量值的误差超过 50μ g· g－ 1外，其余均小于 50μ g· g－ 1，而控制棒价值、硼浓度微分价值、温度系数误差也均在工程要求的范围之内。
Based on the advanced 2-D and 3-D nonlinear iteration nodal code with high accuracy and efficiency NLNEM and intro-nodal pin power reconstruction code 3DPPREC, a multi-functional, physics-hydraulic coupled code of PWR fuel management calculation CSIM-3 is encoded. The load following calculation for cycle 1 and 2 of Qinshan Nuclear Power Plant has been performed. Compared with the measured data, the results show that the maximum errors of relative power density and burn-up are -1. The maximum errors of control rod value, differential values of boron concentration and moderator temperature coefficient are all within the permissible limits of engineering requirement.
