Zusammenfassung: | The invention belongs to the technical field of storage and transport of spent fuel, in particular to a shock absorber of a spent fuel container with functions of sealing welding and flame resistance. The shock absorber comprises an upper shock absorber, a lower shock absorber and a metal backing board. The upper shock absorber and the lower shock absorber are arranged at two ends of the spent fuel container and used for absorbing impact energy during normal transport and accident dropping condition. The upper shock absorber comprises an inner side cover, an outer drum, shock absorbing material and sealing welding and flame resistant devices. The inner side cover and the outer drum are welded into be a bowl-shaped cavity structure, the interior of which is filled with shock absorbing material. The outer side cover is welded with the outer drum so that the bowl-shaped cavity structure filled with shock absorbing material is sealed, thereby forming the sealed bowl-shaped cavity structure. The sealing welding an |
