This invention was made to eliminate the drawbacks of the conventional ones as described above, and includes a phase detection transformer for controlling the current of a movable gripper coil and a phase detection transformer for controlling the current of a stationary gripper coil. Even if one of them fails and current control becomes impossible, the current control circuit of the other is still in good condition and supplies the current necessary to hold the control rods, so even if one of them fails, control can be maintained. The purpose is a control rod control device that can prevent rods from falling.
