【摘要】：第三核电堆型AP1000有望成为我国未来核电发展的主力堆型。分析AP1000的设计理念及其功率运行特点,结果表明,AP1000机组具有良好的负荷调整特性,能参与电网的调峰运行。在掌握AP1000堆芯反应性物理特点及与中子通量耦合特性的基础上,建立堆芯仿真模型。仿真研究了堆芯内小扰动和堆芯外大扰动情况下,堆芯状态变量和控制变量的相互作用关系。结果表明,状态变量引起的反应性主要应对小扰动后堆芯稳定运行问题,控制变量引起的反应性保证堆芯在大扰动后能按照扰动轨迹运行。
[Abstract]:The third nuclear reactor type AP1000 is expected to become the main type of nuclear power development in China in the future.The design concept and power operation characteristics of AP1000 are analyzed. The results show that the AP1000 unit has good load adjustment characteristics and can participate in the peak-shaving operation of power grid.On the basis of mastering the physical characteristics of reactivity and coupling with neutron flux of AP1000 reactor core, a core simulation model is established.The interaction between the core state variables and the control variables is studied by simulation under the condition of small disturbance inside the core and large disturbance outside the core.The results show that the reactivity caused by the state variables should be mainly concerned with the stable operation of the core after small disturbance, and the reactivity caused by the control variables can ensure that the core can run according to the disturbance trajectory after the disturbance.
