摘要： PURPOSE:To prevent possible buckling with the application of a shearing force on a vessel shell, by providing a skew rib on a cylinder of a fast breeder tank type nuclear reactor vessel to enhance rigidity of the vessel. CONSTITUTION:One circle of a skew V-shaped rid 17 is arranged on the circumference of a shell section of a fast breeder tank type nuclear reactor vessel 1 to reinforce the container 1 aslant. When an earth quake occurs to apply a horizontal seismic load, the nuclear reactor vessel 1 vibrates at the lower part thereof with the upper part thereof 1 fixed as the nuclear reactor vessel 1 is supported with a support of a roof slab 3. In such a case, a possible shear buckling can be prevented with the skew rib 17 arranged against a force generated aslant to the shell of the vessel 1.

摘要： PROBLEM TO BE SOLVED: To reduce seismic inertial force acting on a structure having a traveling wheel. SOLUTION: A traveling wheel 3 is supported by a saddle 1 and a traveling wheel supporting member 2 at a traveling part of both ends lower parts of a building having a traveling wheel, and is put on a traveling rail 4 to move in a horizontal direction. Near the traveling wheel, a falling down preventive fitting 8 are placed through a preventive fitting supporting member 6 so as to catch on a web 7 of the traveling rail 3 and point contact with a bottom surface of the web 7 of the traveling rail 3.

摘要： PURPOSE:To simplify a structure while enhancing workability, by forming a hermetically closed space to the outside of bellows so as to surround the same and pressurizing or evacuating said space to perform a pressure resistance/ leakage test. CONSTITUTION:The connection part of the disc shaped protective ring 9 provided to the outside of bellows and a cylindrical protective cover 10 is welded to impart air-tightness and a gasket 6 is inserted in the gap part and clamped and sealed by a clamp plate 17 and a clamp bolt 19 to form a hermietically closed space to the outside of the bellows 6 while a test plug 18 is provided to the protective cover 10 to pressurize or evacuate said hermetically closed space. By this mechanism, because a worker is released from entering an atomic reactor receiving vessel under a highly radioactive condition and a guard pipe becomes unnecessary, work becomes easy and the structure of a test apparatus can be simplified.
摘要翻译：目的：为了简化结构，同时提高可加工性，通过在波纹管的外侧形成一个气密封闭的空间，以便围绕它，并对所述空间进行加压或抽空以进行耐压/泄漏试验。构成：将设置在波纹管外侧的圆盘形保护环9和圆筒形保护盖10的连接部分焊接起来以赋予气密性，并且将垫片6插入间隙部分中，并由夹板17夹紧和密封以及夹紧螺栓19，当将试验塞18设置在保护盖10上以对所述密封空间加压或抽空时，形成到波纹管6外部的非闭合空间。通过这种机制，由于工人在高度放射性条件下被释放而不能进入原子反应堆接收容器，并且不需要保护管，所以工作变得容易，并且可以简化测试装置的结构。

摘要： PROBLEM TO BE SOLVED: To improve placing work capability of spacers between racks and aseismatic structure of the rack. SOLUTION: In a fuel rack 1, an integrated spacer 3 of structure supporting the upper part is provided and the integrated spacer 3 consists of a tapered spacer 4 filling the gap between fuel racks 1 and between the fuel rack 1 and fuel pool wall 2, and a frame 5 combining each spacer 4 in one. The integrated spacer 3 can be placed on the fuel rack 1 by the self-weight of whole integrated spacer 3 without fixing by directly welding to the fuel rack 1 and fuel pool wall 2 so that whole fuel rack and fuel pool wall are supported in one in the constitution.

摘要： PURPOSE:To prevent the local buckling of a nuclear reactor vessel by connecting the supporting structure of the reactor core to the barrel part of the reactor vessel, providing the supporting part of the reactor vessel to the barrel part as well and matching the positions thereof. CONSTITUTION:The core supporting structure 5 is the ribbed structure to support the core 4 and is joined to the reactor vessel 1. A reactor supporting mechanism 16 exists in a cylindrical shape by passing a safe vessel 2 at the same height as the height of the joint part thereof and is joined to a reactor building 12 to support the entire part of the reactor. Seismic load acts over the entire part of the reactor but the load acting on the core 4 is transmitted through the structure 5 to the vessel 1 when an earthquake arises at this time. Since the vessel 1 has the structure 16 in the same position as the joint position of the structure 5, the load transmitted from the structure 5 can be passed to the reactor building 12 without exerting the load on the vessel 1. The local buckling of the vessel 1 is thus prevented.
