    摘要: The control rod includes a plurality of elongated tubes containing neutron-absorbing material in a planar array to form wings on opposite sides of a central axis of the control rod. Each tube is formed with a plurality of protuberances in excess of four such that the tubes can be welded to adjacent tubes with the weld lines disposed inwardly of the side surfaces of the wings to improve the flexibility of the control rod. The wings of each planar array have connecting elements of each other planar array thereof, enabling lateral movement of the planar arrays of wings relative to one another to further enhance flexibility and movement of the control rod between the fuel channels of the nuclear core.
