【摘要】：AP1000核电厂非能动贮水箱需保证72 h供水。在地震作用下,水的晃动对核电厂动力响应产生重要的影响。该文基于任意拉格朗日欧拉流固耦合算法,建立AP1000核电厂重力水箱4种水位和3种通风口高度的全耦合精细有限元分析模型,分析满足RG1.60反应谱的核电人工波作用下重力水箱的动力响应,参数化分析核岛厂房顶点加速度响应与水箱水位、通风口高度与结构动力响应之间的相互作用规律,探究核电厂重力水箱的最优水位和通风口。计算结果表明:在满足核电厂供水的条件下,当水位4,通风口C时,AP1000核电厂屏蔽厂房动力响应最小。
[Abstract]:The non-active storage tank of AP1000 nuclear power plant should ensure 72 h water supply. Under earthquake action, water sloshing plays an important role in the dynamic response of nuclear power plant. Based on an arbitrary Lagrangian Euler fluid-solid coupling algorithm, a fully coupled fine finite element analysis model of four water levels and three vent heights for gravity tank in AP1000 nuclear power plant is established in this paper. The dynamic response of gravity tank under the action of artificial wave of nuclear power plant satisfying the RG1.60 response spectrum is analyzed. The interaction between the acceleration response of the apex of the nuclear island powerhouse and the water level of the tank, the height of the vent and the dynamic response of the structure is analyzed parameterized. To explore the optimal water level and vent of gravity tank in nuclear power plant. The calculation results show that under the condition of satisfying the water supply of the nuclear power plant, when the water level is 4, the dynamic response of the shield plant of AP1000 nuclear power plant is minimum when the water level is 4 and the vent is C.
