This patent describes a process for forming an elongate flat planar member comprising a portion of a nuclear reactor control rod for insertion within the core of a nuclear reactor for control of the reaction. It comprises: providing tubes defining cylindrical volumes and having square cross section, each the tube defining a cylinder of constant side wall thickness sufficient for defining there within the cylindrical volume for the containment of neutron absorbing poisons; providing on each the tube four discrete right angle corner sections integrally formed to the constant side wall thickness cylinder having a placement on the outside of the cylinder t 90{degrees} intervals to the side walls of the constant side wall thickness tube, the four corner sections defining four volumes of increased thickness in the tube wall defined therebetween; and fastening the tubes in juxtaposed side-by-side relation with the two discrete right angle corner sections of one tube adjoining two discrete right angle corner sections of an adjacent tube.
