Zusammenfassung:	The utility model belongs to the technical field of spent fuel receiving and storage, and particularly relates to an improved fuel assembly long-rod lifting tool. The technical problem solved by the utility model is to provide the improved fuel assembly long-rod lifting tool for increasing reliability and safety of a fuel assembly long-rod lifting tool during an operation process based on defects. The technical scheme of the utility model is that: the improved fuel assembly long-rod lifting tool comprises two sets of three-piece fuel assembly long-rod lifting tools, wherein the three-piece fuel assembly long-rod lifting tools comprise one single-purpose fuel assembly long-rod lifting tool and two spare use fuel assembly long-rod lifting tools. The fuel assembly long-rod lifting tool is characterized in that the upper end portion of the lifting tool is provided with a core shaft lifting mechanism, and a lever structure form is adopted.
