摘　　要：乏燃料贮存架是核设施中安全级设备,其自由放置在乏燃料水池中,对其进行抗震分析具有重要意义。针对某研究堆乏燃料贮存架的特点,采用谱分析法和简化模型-时程分析法相结合的分析方法对乏燃料贮存架进行抗震计算,克服了谱分析法和时程分析法各自缺点,提高了乏燃料贮存架抗震计算效率。计算结果表明,研究堆乏燃料贮存架具有足够的结构强度贮备,在各种工况下均能保持结构稳定性和完整性,不发生倾覆,不与池壁发生碰撞,满足相关规范要求。Spent fuel storage rack is a key equipment of nuclear facility. And it is freestanding in spent fuel pool. Therefore, it is very important for seismic analysis of the rack. In this study, response spectrum and time history analysis method was used to perform seismic calculation for spent fuel storage rack of research reactor. The techniques overcame shortcomings of both methods and improve efficiency. As the calculated results, the rack had sufficient structural strength and was safe with any specific condition. Besides, the rack didn＇t jump and bump into the wall of the pool. The results proved that the design satisfied requirements of specifications.
