为评估满载组件的两台乏燃料贮存栺架自由放置在装载井中的安全性,运用时程分析法对其在地震载荷下的响应进行分析。针对乏燃料贮存栺架在装载井内的布置情况,考虑了其与池底的摩擦接触、与贮存组件的碰撞接触以及在水池中的浮力、阻尼、流固耦合效应。通过计算可得到乏燃料贮存栺架在地震载荷下的位移及支反力结果。分析乏燃料贮存栺架的位移结果可知,其滑动位移与水隙宽度有关,且不发生倾覆,不与相邻物体发生碰撞。根据乏燃料贮存栺架所受支反力对栺架底板、支腿强度进行分析,确认无损坏风险。
Abstract：In order to evaluate the safety of two fully loaded fuel storage cells placed freely in the loading well, time history analysis was used to analyze their responses under seismic loads. Considering the arrangement of the spent fuel storage grid in the loading well, the friction contact with the bottom of the tank, the collision contact with the storage components and the buoyancy, damping and fluid-solid coupling effects in the tank are considered. The results of displacement and supporting reaction of spent-fuel storage grid under seismic load can be obtained by calculation. By analyzing the displacement results of spent fuel storage grid, it can be seen that its sliding displacement is related to the width of water gap, and it does not overturn or collide with adjacent objects. The strength of the bottom plate and supporting leg of the grid is analyzed according to the supporting reaction force of the spent fuel storage grid, and it is confirmed that there is no risk of damage.
