摘要:PURPOSE:To prevent excessive stress occurring in the neighborhood of the mounting part of a control rod guide tube by setting an upper plate bundling the upper terminal part of the control rod guide tube in such a way that it can be moved
upward/downward and rotatably freely. CONSTITUTION:A guide tube 25 is descended gradually advancing a control rod column upper shielding body 103, and the lower terminal of the control rod guide tube 25 is inserted and connected to the control rod insertion hole 23 of the control rod column upper shielding body 103 with the tapered plane of a lower plate 105 setting a nuclear fuel column upper shielding body 104 as guide. At this time, the guide tube 25 is pressed with a belleville spring 108 finally since a lower frame 107 and the upper plate 106 can be moved upward/downward freely, and is fixed with an almost constant power. By employing such constitution, it is possible to prevent the excessive stress applied on the control rod column upper shielding body 103 and the nuclear fuel column upper shielding body 104 when performing connection. Also, an excessive load on the supporting part of the guide tube 25 can be prevented from occurring.
