置。A guide tube, an electromagnet attached to the lower surface of a disc screwed together and driven in the axial direction by a motor provided at the upper part of the guide tube, and an electromagnet disposed in the guide tube and connected to the electromagnet at the upper part. An extension tube that can be magnetically moved toward and away from the reactor, a latch mechanism connected to the lower part of the extension tube, a control rod that can be connected to and disconnected from the extension tube by the latch mechanism, and a control rod for accelerating and dropping the control rod into the reactor core. In a control rod drive device comprising an acceleration spring provided outside the extension tube and an acceleration tube that transmits the force of the acceleration spring to the control rod, the acceleration tube is divided into an upper acceleration tube and a lower acceleration tube. In addition, two deceleration mechanisms, an upper and a lower part, are provided to reduce the falling speed of these accelerator tubes, and a permanent magnet is installed in the lower accelerator tube, and a coil is wound around the guide tube in an area through which the permanent magnet passes. A control rod drive device characterized by:
