The invention discloses a spent fuel transporting container hanging basket. The spent fuel transporting container hanging basket comprises a top plate assembly, a base plate assembly, a storage sleeve, connecting rods, supporting plates, heat transfer plates and positioning pieces, wherein the storage sleeve and the connecting rod are parallel to each other and are vertically arranged, and the upper ends and the lower ends of the storage sleeve and the connecting rod are connected with the top plate assembly and the base plate assembly respectively; at least one heat transfer plate is arrangedbetween every two adjacent supporting plates, the supporting plates and the corresponding heat transfer plate are arranged between the top plate assembly and the base plate assembly in parallel, thestorage sleeve movably passes through the supporting plates and the corresponding heat transfer plate, and the connecting rod detachably passes through the supporting plates and the corresponding heattransfer plate; the positioning pieces detachably sleeves the corresponding connecting rod; and every two adjacent positioning pieces on the same connecting rod are used for clamping the corresponding heat transfer plate. Therefore, the spent fuel transporting container hanging basket provided by the invention is high in heat conductivity and high in structural strength, and can also be used fortransportation and storage.
