摘要
近代核电工业发展迅速,核电安全问题越来越受到重视。2011年日本福岛核泄漏事件在世界核电安全问题上产生重大影响,尤其是中国,研究地震作用下核电安全具有重大意义。第三代核电技术AP1000应用了非能动安全系统,来减轻或阻止重大事故的发生,获得了各国的关注。首先介绍了AP1000的非能动安全壳冷却系统PCS以及安全壳厂房;其次分析和比较了单向和双向地震输入下水箱对整体结构耗能效应和地震动响应的影响。在该过程中,通过应用耦合拉格朗日技术(CEL)和简化的附加质量法建立了ABAQUS模型,模拟了水和结构之间的相互作用,同时研究了不同储水量下重力水箱对安全壳厂房地震动反应的影响。研究结果表明:水箱内液体的晃动对结构没有明显的耗能效应,并且储水量的增加会加强地震动反应;最后给出了一些建议和讨论。
With the rapid development of nuclear power industry in modem times, more and more attention is paid to the safety of nuclear power. In 2011, Japan Fukushima serious nuclear accident brought a deep influence on the worldg nuclear power development, especially for China, so it is of great significance to study the safety of nuclear power under earthquake. Then the third generation nuclear power plant, applying passive safety system to prevent and mitigate the serious accidents, is getting many countries＇ attention. In this paper, firstly the PCS （Passive Containment Cooling System） gravity drainage water tank of a nuclear power plant （AP1000） is introduced. 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 does not play a shocking absorbing effect on the building, while the ground motion response of the building increases along with the volume of the water. Finally, some suggestions and discussions are presented.
