摘要： PROBLEM TO BE SOLVED: To suppress a flow vibration in an instrumentation guide tube to prevent wear of the instrumentation guide tube. SOLUTION: 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 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, an upper pressure regulation hole and a lower pressure regulation hole are formed at two upper and lower positions in a side face of an upper reactor core support column 21. A cooling material, having flown from the upper end of the guide tube into the guide tube, flows from the inside to the outside of the guide tube through a gap between the thimble tube and the upper hole, flows from the inside to the outside of the upper reactor core support column through the upper pressure regulating hole, flows 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 flows from the inside to the outside of the upper core reactor support column through the lower pressure regulating hole.

摘要： PROBLEM TO BE SOLVED: To provide a storage structure which can restrain the collision of accommodated objects with a storage container. SOLUTION: Racks 10 for accommodating spent fuel rods 5, stored objects, are stored in the water 38 pooled in a pit 30, and a buffer block 20 alienated from the inner wall 32 of the pit 30 and the racks 10 is placed between them. Owing to this structure, the vibration is attenuated by the water 38 pooled in the pit 30 even if a big vibration such as an extensive earthquake occurs, and the racks 10 also come into contact with the buffer block 20 even if they jolt hard because the vibration is not attenuated completely by the water 38. Therefore, the vibration of the racks 10 is absorbed by the buffer block 20 when they come into contact with it and the vibration stops. As a result, the collision of the racks 10 as accommodated objects with the pit 30 as a storage container can be restrained. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供一种可以限制容纳物体与存储容器碰撞的存储结构。
解决方案：用于容纳乏燃料棒5，存储物体的机架10被储存在汇集在坑30中的水38中，并且与坑30的内壁32和机架10分离的缓冲块20被放置它们之间。由于这种结构，即使发生诸如大地震之类的大振动，也可以将集水在坑30中的水38的振动衰减，并且，即使摇架10也因为缓冲块20而摇晃振动不会被水38完全衰减。因此，当缓冲块20与其接触并且振动停止时，齿条10的振动被缓冲块20吸收。结果，可以抑制作为容纳物体的货架10与作为储存容器的坑30的碰撞。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent a conventional multistage floating ring seal from self-excited oscillation by a simple constitution which often causes accidents such as causing the self-excited oscillation in which floating rings in respective stages are alternately self-excited, touching the floating ring with a main shaft sleeve, and deteriorating a sealing performance. SOLUTION: When the natural frequencies of the floating rings in the respective stages are differed, the self-excited oscillation can be prevented. Therefore the shapes, materials, and quantities of the floating rings, and shapes and spatial dimension of floating ring receivers are changed so as to differ the natural frequencies of the floating rings.

摘要： PROBLEM TO BE SOLVED: To provide an underwater structure whose earthquake resistance is heightened, by eliminating external force to be applied to a submerged structure in the case an earthquake occurs. SOLUTION: This underwater structure 1 is so constituted that their own mass Ma ∼Mn of a plurality of elements 3a∼3n are approximately equivalent to mass ρ×Va ∼ρ×Vn of water having the same capacity as that of volume Va ∼Vn to be formed of the elements 3a∼3n, in the case a plurality of elements 3a-3n cut in round slices so as to divide the underground structure 1 in the vertical direction are assumed. By the constitution, even in the case an earthquake occurs, apparent external force no longer acts, relative displacement in the vertical direction occurring in the underwater structure 1 and occurrence of stress are also eliminated, and even in the case an earthquake occurs, the underwater structure 1 capable of greatly reducing the possibility of cracks or damages.
