摘要： PURPOSE:To transport a large amount of used fuel at a time by composing a connection passage of a large-diameter communication hole in a closed section shape and a bellows type expansible joint. CONSTITUTION:Communication holes 9 and 10 which have large diameters and are sectioned rectangularly are formed in vertical wall parts 7 and 8 facing fuel storage pools 1 and 2 at mutual matching positions and the communication holes 9 and 10 are connected by the bellows type expansible joint 11 made of stainless steel which has a large diameter and is sectioned rectangularly. Consequently, if an earthquake takes places, two buildings behave differently, but the relative displacement in the earthquake is absorbed by the motion of the bellows type expansible joint 11 to increase the safety. Further, the communi cation holes 9 and 10 and bellows type expansible joint 11 are sectioned rectangu larly, namely, in the closed section shape, so a decrease in the strength of the vertical wall parts 7 and 8 is minimized to maintain the soundness in an earth quake.

摘要： PURPOSE:To partition the covering body without welding the hermetically sealed enclosure to a structure body by fixing a partition plate to the covering body by melt-sticking, etc., and sealing the gap between the partition plate and a metallic plate with a gasket having elasticity. CONSTITUTION:Partition plates 6A and 6B are fixed to the covering body by melt-sticking, etc., and the gap between the partition plates 6A and 6B and metallic plate is sealed with the gasket 8 having elasticity. In this case, when the gasket 8 is pressed to seal the gap, the space in a test channel 1 is partitioned into two independent spaces with the partition plates 6A and 6B and those spaces are shield from each other and held airtight. Then, piping is performed and pressure air is fed to the spaces to test airtightness. Similarly, the range of the test is narrowed down successively to a specific partition position to form a small area, and then the covering body is partitioned without welding the sealed container to the structure body.
