    • A fuel assembly handling tool that can be lowered onto the top nozzle of a fuel assembly, positively latch the top nozzle, unlatch from the top nozzle, and be raised off the top nozzle of the fuel assembly. The tool head, that interfaces with the top nozzle has load bearing grippers that latch onto the fuel assembly, that are located in a storage position up within the tool while the tool is lowered onto the fuel assembly. The gripper fingers are then lowered into position during the latching process, and are raised back to the storage position during the unlatching process. In the storage position, the gripping fingers are spaced above the fuel assembly top nozzle when the tool head is resting on the nozzle.
    • 可以将燃料组件处理工具下降到燃料组件的顶部喷嘴上,将顶部喷嘴正确地锁定,从顶部喷嘴脱开,并从燃料组件的顶部喷嘴上升起。 与顶部喷嘴相连接的工具头具有锁定在燃料组件上的负载夹持器,当工具下降到燃料组件上时,工具头位于工具内的存储位置。 然后在锁定过程期间将夹持器指状物下降到适当位置,并且在解锁过程中被提回到存储位置。 在存放位置时,当工具头靠在喷嘴上时,把持爪在燃料组件顶部喷嘴上方间隔开。
