[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.
