Abstract
A single guide tube and tube sheet tube, as an upper extension, carries a nuclear control rod in storage, poised for downward insertion into the guide tube. An inner tube, termed a bypass tube, is mounted within the cylindrical tube sheet tube and fitted closely about the control rod. Mounting connections between the upper and lower ends of the bypass tube and the tube sheet tube are provided to route the coolant in control of the rod vibration.
