摘要
应用海洋条件下堆芯冷却剂系统运行状态的仿真数学模型 ,使用MathCAD进行编程 ,开展了左右摇摆海洋条件下堆芯冷却剂系统自然循环能力的分析。研究结果表明 :在左右摇摆海洋条件的影响下 ,反应堆中的各种参数均发生了与摇摆相对应的振荡 ,并且在幅值上发生了变化。堆芯流量和堆芯总功率的下降说明 ,左右摇摆的海洋条件对堆芯冷却剂系统自然循环能力有很大影响 。
Natural circulation ability of PWR coolant system under ocean condition is analyzed with the self developed MathCAD programs based on the mathematical simulation model. It shows that parameters in reactor are vibrated with ocean condition, and their amplitude values are changed. Decrease of core mass flow flux and total power proves that natural circulation ability is greatly impacted by ocean condition of swing and has a little decrease.
