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
ut 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.
