摘要： PURPOSE: A control rod driving device with hybrid lower drive type is provided to prevent dropping impact in an emergency stop by laminating a magnetic material steel and a non-magnetic material steel to form a movable element. CONSTITUTION: A extension rod(214) is connected with a control rod(208). A sealed container(212) covers the extension rod and a movable element. An electromagnet casing(216) is installed around the movable element to the outside of the sealed container. A buffer member(238) is installed on the bottom of the sealed container. A step motor(202) is connected to one side of a ball screw(206) which is fixed to a ball nut(204).
