摘要： Disclosed is an unlatching tool (100) that may be used to unlatch a control rod from a control drive. The unlatching tool may include a baseplate (110), a first guide member (120) and a second guide member (125) attached to the baseplate (110), a first frame (140A) and a second frame (140B) attached to the baseplate (110), a stepper motor (155) attached to the first frame (140A), a worm drive (150) attached to the first frame (140A), a cable reel shaft (400) attached to the first and second frame (140A,140B), a hose (200) wrapped around the cable reel shaft (400), and a hook (180) attached to a first end of the hose (200). The hook (180) may include a cylindrical sleeve (182) having at least one finger (184,185,186) configured to fold and unfold. Disclosed also is a method of unlatching a control rod from a control drive.

摘要： A CRDS unlatching tool includes a support assembly and a latching assembly, wherein the support assembly is received within the latching assembly in a manner wherein the latching assembly is moveable relative to the support assembly. The support assembly has a plurality of latch fingers and at least one pin, each of the latch fingers being movable between a latched position wherein the latch finger is structured to engage and hold the CRDS an unlatched position wherein the latch finger is structured to not engage the CRDS. The latching assembly includes a first sleeve member and a second sleeve member, the second sleeve member having at least one slot, wherein the at least one pin is moveably received within the at least one slot. The latching assembly is movable from a latched state to an unlatched state wherein the latch fingers are actuated by the first sleeve member.

摘要： A telescoping rod control cluster assembly change tool for moving control rod assemblies among fuel assemblies in a nuclear facility. The operation of the tool is completely mechanical and the telescoping feature enables the tool to have a relatively low profile when it is being moved and stored without housing a control rod assembly. Rigidly supported alignment cards guide a gripper that attaches to the control rod assembly as the control rod assembly is withdrawn into the tool with the alignment cards preventing any lateral or rotational movement of the gripper.
