Abstract
A device for providing translatory movement of the control rods inside the closed vessel of a nuclear reactor. The rotor of the drive motor for a screw/nut assembly has fixed to it two pivoting arms formed in the poles of the rotor, and these serve as latching members which keep the screw in its raised position. A tubular casing locks these arms in the opened position while the screw is being raised after the control rod has been allowed to fall into the core of the reactor.
