摘　　要：本研究基于仿真软件APROS对两环路核动力系统的一、二回路耦合系统建立了仿真模型,并对此模型进行了功率运行稳态工况和线性变负荷动态工况仿真模拟。结果表明,模型仿真结果的最大稳态相对误差小于5%,与设计值符合较好;动态仿真趋势与热工水力计算程序RELAP5仿真趋势基本一致,验证了模型的有效性。因此,该核动力系统一、二回路匹配性良好,且本文所建立的系统模型能够较准确地模拟核动力系统的运行。Based on the simulation software APROS,this paper establishes a simulation model of the primary loop and secondary loop coupling system of the two-loop nuclear power system,and simulates the steady-state condition of power operation and the dynamic condition of linear variable load.The results show that the maximum steady-state relative error of the model simulation results is less than 5%,which is in good agreement with the design value;the dynamic simulation trend is basically consistent with the simulation trend of the thermal-hydraulic calculation program RELAP5,which verifies the effectiveness of the model.Therefore,the primary and secondary loops of the nuclear power system match well,and the system model established in this paper can accurately simulate the operation of the nuclear power system.
