| 中文摘要: |
| 阐述了压水堆堆芯的数学模型,基于SIMULINK计算仿真工具,建立了相应的仿真模型,并进行了仿真计算.结果表明:不考虑中毒效应,引入反应性阶跃扰动和冷线温度扰动,由于温度效应的负反馈作用,中子密度、燃料温度和冷却剂温度能够到达一个新的平衡,核反应堆具有内在的自稳定性.考虑中毒效应后,反应堆受到的扰动减少,有利于反应堆的自稳定性. |
| 英文摘要: |
| The mathematical model of the PWR core is expounded.Based on SIMULINK tool,the corresponding simulation model is established,and the mode is simulated.The analysis results show that:regardless of the poisoning effects,importing reactivity step disturbance and cold line temperature disturbance,due to the effect of negative feedback of the temperature effect,neutron density,fuel temperature and coolant temperature can reach a new equilibrium.The nuclear reactor has intrinsic stability.Considering the poisoning effects,reactor is fewer disturbed,which is beneficial to the stability of the reactor. |
