Abstract: A control rod drive (CRD) tube, its manufacture, and installation in a pressurized water reactor (PWR) is disclosed. The control rod drive tube includes a tube body adapted to penetrate an aperture in the RPV head and an offset flange formed around a circumference of the tube body at a predetermined location along its length. The offset flange increases circumferentially from a first point along the circumference of the tube body to a second point along the circumference of the tube body.
