核安全二级阀门抗震分析方法

摘要

论述了ASMEBPVCIU对阀门应力分析评定的步骤，介绍了核二级阀门考虑地震载荷的应力分析评定方法。%The seismic analysis method of nuclear safety class 2 valve was discussed. As an example one nuclear safety class 2 valve was analyzed with stress assessment. The results show that the valve is satis- fied with the requirement of ASME BPVC III.
