ABSTRACT:
A control rod support for mounting within a rod guide of a pressure vessel has plural, parallel axial extending passageway openings therein for receiving corresponding control rods of a control rod cluster. A channel extends from the passageway opening and through the support for accommodating each vane of a spider which supports the control rods and provides for telescoping movement of the control rod cluster relative to the rod guide and associated guide rod supports. Spaced interior side walls of the support defining the channel form junctures with the interior side wall defining the passageway opening; and planar wear surfaces extend from the respective junctures of the channel-defining interior side walls a sufficient lateral distance to provide planar-to-convex wear surface interfaces with the corresponding, contiguous surface segments of a generally cylindrical control rod which is received through the passageway opening and urged against the junctures.
