| 摘 要： | 针对堆芯燃料组件在地震作用下可能发生的结构变形及破坏现象,采用简化方法对燃料组件进行时程分析,计算地震工况下格架所受的碰撞载荷以及应力情况,并将计算值与格架的压塌载荷以及导向管的应力限值进行了比较,从而对堆芯燃料组件的结构完整性进行了评估,为日后堆芯燃料组件结构的抗震性能分析计算提供参考。

| Abstract: | Aiming at the structural deformation and failure of the fuel assembly under the earthquake, the fuel assembly is analyzed by the simplified method,and the collision load and stress are calculated under the seismic condition.And then the calculated values are compared with the crush load of the framework and the stress limit of the guide tube,thereby evaluating the structural integrity of the fuel assembly,in order to provide a reference for the analysis and calculation of the seismic performance of the fuel assembly structure in the future |
