    摘要： A control rod drive mechanism (CRDM) comprises a lead screw, a motor threadedly coupled with the lead screw to linearly drive the lead screw in an insertion direction or an opposite withdrawal direction, a latch assembly secured with the lead screw and configured to (i) latch to a connecting rod and to (ii) unlatch from the connecting rod, the connecting rod being free to move in the insertion direction when unlatched, and a release mechanism configured to selectively unlatch the latch assembly from the connecting rod.

    摘要： A sensor (10) assembly for indicating the location of a leadscrew (20) relative to a probe tube (18), the leadscrew (20) forming part of a nuclear control rod and the probe tube (18) being moveably connected to the leadscrew (20). The sensor (10) assembly including a primary electromagnetic coil (12) arranged to generate a time varying magnetic field; and a secondary electromagnetic coil (14) arranged to detect the time varying magnetic field as affected, directly or indirectly, by the leadscrew (20) moving relative to the probe tube (18) and to output, on the basis of the detected time varying magnetic field, a signal indicative of the location of the leadscrew (20) relative to the probe tube (18). The primary electromagnetic coil (12) and the secondary electromagnetic coil (14) comprising copper and nickel.

    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 rotary actuator (10) has a driven element (20) comprising a plurality of recesses (30) that are spaced in a circumferential arrangement around an axis of rotation (22) of the driven element (20) by a spacing angle (32), and first, second and third latch elements (40, 60 70) that are each movable between a retracted position (42), and an extended position (44) in which it is engageable with a corresponding one of the recesses (30). Sequential movement of the first, second and third latch elements (40, 60 70) between retracted and extended positions causes rotation of the driven element (20).
