摘要
为评价某核电厂最终热阱冷却塔内的填料装置的抗震性能,对填料装置模型进行合理简化,用有限元法建立计算模型,在各种工况下进行载荷组合计算,对装置进行自重载荷下的静态分析和地震载荷下的动态响应分析,并按ASME规范对计算结果进行评定.结果表明该填料装置的设计满足该核电厂的抗震要求.
To evaluate the anti-seismic performance of the packing device in ultimate heat sink cooling tower of nuclear power plant, the packing device model is simplified reasonably, the computation model is established using finite element method, the load combinations under various working condition are calculated ,the static analysis under deadweight load and the dynamic response analysis under seismic loads are carried out, and the calculation results are evaluated according to the ASME standard. The results show that the design of the packing device meets the anti-seismic requirement of the nuclear power plant.
