Analysis of Seismic Response of Passive Tank of a New Generation Nuclear Power Plant


Abstract eng:
In 2011, Japan Fukushima serious nuclear accident brought a deep influence on the world's nuclear power development, especially for China. Then the third generation nuclear power plant, applying passive safety system to prevent and mitigate the serious accidents, is getting more and more attention. In this paper, firstly the PCS (Passive Containment Cooling System) gravity drainage water tank of a nuclear power plant (AP1000) is introduced. AP1000 as the third generation of nuclear power technology has a unique concept in the field of passive safety design. Then the energy dissipation effect and the responses of different kinds of earthquake inputs to a tank are generally analyzed and compared, which includes different wave frequency, single and bidirectional input directions and so on. In the analysis process, an ABAQUS model is used to simulate the fluid structure interaction between water and tank wall by using the Coupled Euler Lagrange analysis technique (CEL) and the simplified added mass method. Meanwhile the effect of tanks with different volume of water storage on the containment building is also studied, and it shows that the sloshing of the water in the tank did not play a shock absorbing effect on the building, while the ground motion response of the building increased along with the volume of the water. Finally, some suggestions and discussions are presented.
