ABSTRACT:
The control rod for a nuclear reactor includes a plurality of wings each having segments of neutron absorbing material exposed along the length of the rod. During refueling, the segments of neutron absorbing material are rearranged within the control rod and the control rod is reinserted into the reactor core. By rearranging the segments, optimum use of the depletion capacity of each segment is effected, maximizing the number of cycles for which the control rod may be used.
