Mathematic Model for Nuclear Power Station with Integrated Secondary-Loop

School of Nuclear Science and Engineering, Shanghai Jiao Tong University, Shanghai, 200040, China

摘要: 采用RELAP5程序对岭澳二期1000 MW核电站进行了核岛和常规岛的热工水力系统以及控制系统建模,分析了汽轮发电机负荷从100%FP瞬时阶跃下降到90%FP后再从90%FP瞬时阶跃上升到100%FP瞬态运行工况。通过对瞬态计算结果进行分析,显示了完整闭合的二回路模型在分析核电站负荷阶跃瞬变过程的优越性。

Abstract: This paper models the thermal-hydraulic and control systems of nuclear and conventional islands of Ling’ao PhaseⅡ 1000 MW Nuclear Power Station by using RELAP5,and analyzes the turbine load from 100%FP（Rated power） step transient to 90%FP and then from 90%FP step transient to 100%FP.In the simulation of the transient process,the superiority of the integrated secondary-loop model in the analysis of turbine load step transient changes has been indicated.
