Dual control rod drive mechanism and control method in nuclear power

摘要

The present invention relates to a redundant control rod drive apparatus for a nuclear reactor and a control method thereof, and more particularly, to a redundant control rod drive apparatus for a nuclear reactor that drives a wheel for inserting or withdrawing a control rod into a reactor, And a first worm gear (20) coupled to the wheel (100) and driving the wheel (100) through a rotation operation, wherein the wheel (100) moves the position of the control rod A first worm driving part 200 for controlling the driving of the first worm gear 20 and a second worm gear 30 for driving the wheel 100 through rotation, A second worm drive unit 300 for controlling the driving of the second worm gear 30 and an external input unit 410 for receiving a drive command for controlling driving of the wheel 100 from the outside, Command to the first worm drive (200) and the second worm The first worm gear 20 and the second worm gear 30 are coupled to two points of the wheel 100 so as to be rotated And drives the wheel 100 through the operation of the control unit.
