Abstract

Positioning device for control rods in nuclear reactor Device comprises a coil for creating a magnetic field, a fixed pole which attracts a movable working pole. The fixed pole is extended and a movable buffer pole is placed between the fixed and working poles. There is a first air gap between the buffer and fixed poles as well as a second stepped air gap between the ends of the working pole and the ends of the buffer and extension poles. The ends of the buffer and extension poles are spaced at different distances from the working pole.
