A fuel assembly transport container and a top capping device thereof, the top capping device comprises a door panel (2221) for capping the upper end of the container cavity of the transport container, and a door panel (2221) to be installed in the transport container (4) A locking structure for axially locking the fuel assembly (3). The locking structure comprises a first locking rod (2222) and a second locking rod (2223) which are mounted on the door panel (2221) in an adjustable axial position, the first locking rod (2222) is located in the middle of the door panel (2221), and Opposite to the center of the upper tube seat of the fuel assembly (3), the second locking rod (2223) includes at least two, which are centrally symmetrically arranged on the circumference of the first locking rod (2222). Without disassembling and assembling the door panel (2221), the first locking rod (2222) and the second locking rod (2223) of the locking structure can be adjusted independently respectively, which can be used for pressing the fuel assembly without related components (3), the fuel assembly (3) with the relevant components can be compressed, and the device is multifunctional. The device is easy to operate and simple to maintain. |
