摘要： PROBLEM TO BE SOLVED: To suppress the collapse of an impact buffer body due to buckling.
SOLUTION: An upper impact buffer body 20 having an axially symmetric U-shaped cross section is constituted by filling its interior with wood and surrounding its exterior with a steel cover 21. The upper impact buffer body 20 covers the upper surface of a secondary lid 6 and the side surfaces of the upper end part of the peripheral surfaces of an inner tube 2 by fitting the inner tube 2 in a recession formed in its upper surface. A lower impact buffer body 10 has the same constitution as that of the upper impact buffer body 20. Laminated plates 25 are arranged in the upper impact buffer body 20 in such a way as to face the outer circumferential surface of the inner tube 2. Each laminated plate 25 is filled in regions radiatively divided by radiative ribs 23 between the concentrically arranged steel cover 21 and a cylindrical rib 22. Each laminated plate 25 is arranged in such a way that the normal of the surface of each lamination of the laminated plate forms an angle of 25° with the circumferential direction of a cask. In the upper impact buffer body 20, balsa 26 is filled in parts except the laminated plates.

摘要： PROBLEM TO BE SOLVED: To remove residual water in a gasket and a gasket groove part in a dry type storage hermetic container.
SOLUTION: In a partial air space previously arranged in the water, a hermetic container main body and its lid are fastened together. In this way, water can be removed from a hermetic boundary using the gasket and the like. When a drain hole is arranged in the container main body immersed in the water, a water level of the container main body can be lowered only by putting a bell-shaped member having an opening part in the lower side, in which the air is included, over the container main body, and the hermetic container main body and its lid can be fastened in the air. If no drain hole is arranged in the immersed container main body, the water level cannot be lowered only by putting the bell-shaped member over the container main body, so that the hermetic container main body and its lid can be fastened together by arranging a mechanism or a device lowering the water level of the container main body.

摘要翻译：要解决的问题：去除干式储存密封容器中的垫圈和垫圈槽部分中的残留水。解决方案：在先前设置在水中的局部空气空间中，将密封容器主体及其盖紧固在一起。以这种方式，可以使用垫圈等从密封边界去除水。当在浸没在水中的容器主体中布置排水孔时，只能通过将具有开口部的钟形构件放置在其中包含空气的下侧中来降低容器主体的水位在容器主体之上，并且密封容器主体及其盖可以紧固在空气中。如果在浸没的容器主体中没有设置排水孔，则仅通过将钟形构件放在容器主体上而不能降低水位，使得密封容器主体及其盖可以通过布置机构或降低容器主体的水位的装置。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a radioactive material storing cask capable of securing sealability at the transportation time even if an abnormal sealing member exists, and of increasing the quantity of the radioactive material stored inside.
SOLUTION: This transporting storing cask 14 is equipped with a cask body 15 and a pair of buffers 6, 16. An opening part formed on a body 1 of the cask body 15 is blocked by mounting a primary lid 2 on one end of the body 1 across a primary seal 9. A secondary lid 3 for covering the primary lid 2 is mounted on one end of the body 1 across a secondary seal 10. The buffer 6 has a buffer flange 7 and a lumber 17. The buffer flange 7 is mounted on a circular buffer mounting flange 8A installed on the body 1 across an elastic seal 11. The buffer flange 7, the buffer mounting flange 8A and the elastic seal 11 form a new sealing boundary.
