摘要
安全壳再循环滤网作为三代非能动AP/CAP核电系统的重要组成部分,对保证在设计基准事故下安全壳堆型冷却系统正常运行非常重要.必须保证核电站在发生事故时,设备整体浸泡在水中也能满足抗震性能的要求.应用ANSYS有限元软件进行模态分析和谱分析,并根据ASME BPVC-Ⅷ的相关要求,对再循环滤网进行地震载荷作用下的结构完整性和可运行性评价.结果表明,再循环滤网在核级使用工况下能满足相关抗震性能的要求.
Abstract
The containment recirculating filter,as an important part of the third-generation passive AP/CAP nuclear power system,is crucial for ensuring the normal operation of the contain-ment reactor cooling system under design basis accidents.It must be ensured that,in the event of an accident of the nuclear power plant,the equipment can meet the requirements of seismic performance even when it is fully immersed in water.Finite element software ANSYS is used for modal analysis and spectral analysis,and according to the relevant require-ments in ASME BPVC-Ⅷ,the structural in-tegrity and operability of the recirculating filter under the action of seismic loads are evaluated.The results show that the recirculating filter can meet the relevant requirements of seismic performance under nuclear-grade operating conditions.
