Publication number: 20090185652Abstract: It is an object of the present invention to suppress, while securing heat transfer performance and a subcritical function, a fall in manufacturing efficiency when a material hard to be extruded such as a B-Al material is used. To attain the object, a recycled fuel assembly storage basket 1 according to the present invention is configured by combining first square pipes 10 and hollow tabular members 20. Storage cell rows are formed by linearly arraying a plurality of rows of the first square pipes 10 with projections 10t1 thereof set in contact with each other and projections 10t2 thereof set in contact with each other. The tabular members 20 are stacked in a plurality of stages between storage cells, in which the first square pipes 10 are linearly arrayed, with long side ends TL of the tabular members 20 set in contact with each other.Type: ApplicationFiled: May 15, 2007Publication date: July 23, 2009Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Hiroki Tamaki, Junichi Kishimoto, Yoshiyuki Kawahara, Yuichi Saito, Shinji Ookame

Patent number: 7372933Abstract: A radioactive-material container includes a container body that shields nuclear radiation, which includes a cavity that stores a basket containing a recycle fuel assembly, a lid that covers the cavity, and a metal gasket that includes a sealing area that makes a physical contact with the container body and the lid. The sealing area has a specific shape that disperses tightening stress acting on the metal gasket for a sealing.Type: GrantFiled: July 8, 2004Date of Patent: May 13, 2008Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Katsunari Ohsono, Takeshi Yokoyama, Kazuo Asada, Tadashi Kimura, Yasuhiro Sakaguchi, Shinji Ookame, Masaharu Minami

Patent number: 7215728Abstract: Corner of each square pipe is molded into a terrace shape having steps. When a basket is constructed by these square pipes, steps of adjoining square pipes are assembled together face to face. Fuel rod aggregates are housed inside the square pipes and in a cells formed between the square pipes. Since the adjoining square pipes are assembled in a staggered arrangement, boundaries of the cells are defined by the walls of the square pipes itself.Type: GrantFiled: January 9, 2006Date of Patent: May 8, 2007Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Katsunari Ohsono, Toshihiro Matsuoka, Shinji Ookame

Patent number: 7194060Abstract: Heat conductive fins (107) are welded along both sides of a belt-like member (105a) with a margin left along edges of the both sides, thereby to form a unit (105c). The unit (105c) is welded to a body (101) with the heat conductive fins (107) from the outside of each fin. Next, another belt-like member (105b) is covered over a gap between adjacent belt-like members (105a, 105a), and these members are welded from the outside. With this arrangement, there is no need to weld in a narrow and long space and the entire welding step is carried out from the outside, which makes it easier to assemble a cask.Type: GrantFiled: November 12, 2004Date of Patent: March 20, 2007Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Katsunari Ohsono, Toshihiro Matsuoka, Suguru Hode, Shinji Ookame

Patent number: 6898258Abstract: In the cask, a shape within a cavity of a barrel main body is formed in a shape corresponding to an outer shape of a basket. The basket has a structure obtained by alternately piling up plate-like members vertically. A heat conducting plate is provided on an outer periphery of the plate-like member. Accordingly, since the basket and the cavity are in a state of being in contact state in a wide area, an efficiency of heat conduction is improved.Type: GrantFiled: February 25, 2002Date of Patent: May 24, 2005Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Katsunari Ohsono, Toshihiro Matsuoka, Shinji Ookame
