Seismic Analysis of Containment Recirculat-ing Filters for Advanced Pressurized Water Reactor Nuclear Power Plants
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.
