【摘要】：第三核電堆型AP1000有望成為我國未來核電發(fā)展的主力堆型。分析AP1000的設(shè)計(jì)理念及其功率運(yùn)行特點(diǎn),結(jié)果表明,AP1000機(jī)組具有良好的負(fù)荷調(diào)整特性,能參與電網(wǎng)的調(diào)峰運(yùn)行。在掌握AP1000堆芯反應(yīng)性物理特點(diǎn)及與中子通量耦合特性的基礎(chǔ)上,建立堆芯仿真模型。仿真研究了堆芯內(nèi)小擾動(dòng)和堆芯外大擾動(dòng)情況下,堆芯狀態(tài)變量和控制變量的相互作用關(guān)系。結(jié)果表明,狀態(tài)變量引起的反應(yīng)性主要應(yīng)對(duì)小擾動(dòng)后堆芯穩(wěn)定運(yùn)行問題,控制變量引起的反應(yīng)性保證堆芯在大擾動(dòng)后能按照擾動(dòng)軌跡運(yùn)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.
