A flexible control rod for a nuclear reactor is built up of first, second, third and fourth absorber wings which are arranged in a cruciform configuration. Each wing is divided into a number of wing elements by slots extending substantially perpendicularly to the crossing line of the wings. The first and the third wings are arranged in a first plane with the slots in these wings located pairwise in line with each other, and the second and fourth wings are arranged in a second plane and also with their associated slots located pairwise in line. Further, the slots in the first plane are diplaced in parallel in the direction of the crossing line relative to the slots in the second plane, and the portions of the wing elements adjoining the crossing line of the wings are provided with recesses. This arrangement gives good flexibility without undue loss of strength.
