Control rod guide tube has a supporting surface (5) with a guide surface (6c, 6d, 6e) having a middle axis (x). The surface has a tangent that forms a non-right angle (alpha) with the middle axis or has a line that forms a non-right angle with the middle axis when lengthened. The first surface forms a guide surface that guides the first tube when the tubes are brought together. Preferred Features: The guide surface is essentially planar or slightly bent. The supporting surface also has a second surface (7a, 7b, 7c) forming an angle with the guide surface. |
