    • A structure for suppressing flow vibration of an instrumentation guide tube, the structure being constructed such that an upper hole (37A) and a lower hole (37B) are formed at two upper and lower positions in a side face of the guide tube (27) and that a thimble tube (22) is pressed against the inner peripheral surface of the guide tube (27) by a difference between pressures of a cooling material in the inside and outside of the upper and lower hole (37A, 37B). Further, the structure desirably has an upper pressure regulation hole and lower pressure regulation hole formed at two upper and lower positions in a side face of an upper reactor core support column (21). The upper and lower pressure regulation holes allow a cooling material, having flown from the upper end of the guide tube into the guide tube, to flow from the inside to the outside of the guide tube through a gap between the thimble tube and the upper hole, flow from the inside to the outside of the upper reactor core support column through the upper pressure regulating hole, flow from the lower end of the guide tube into the guide tube, flow from the inside to the outside of the guide tube through a gap between the thimble tube and the lower hole, and then flow from the inside to the outside of the upper core reactor support column through the lower pressure regulating hole.
    • 一种用于抑制仪器引导管的流动振动的结构,该结构被构造成使得在引导管(27)的侧面中的上下两个位置处形成上孔(37A)和下孔(37B) 并且通过上下孔(37A,37B)的内部和外部的冷却材料的压力差,将套管(22)压靠在引导管(27)的内周表面上。 此外,该结构理想地具有在上反应堆堆芯支撑柱(21)的侧面中的两个上下位置处形成的上压力调节孔和下压力调节孔。 上下压力调节孔使得从引导管的上端流入引导管的冷却材料通过套管和上孔之间的间隙从引导管的内部流向外部 通过上部压力调节孔从上部反应堆堆芯支撑柱的内部向外部流动,从导向管的下端流入引导管,通过间隙从引导管的内部流向外部 在顶针管和下孔之间,然后通过下压力调节孔从上核心反应器支撑柱的内部流到外部。
