Patent number: 9070485Abstract: In a reactor vessel (20) covered by cooling water (2), a tubular frame (10) with a bottom is hung within the cooling water (2) while still having an air environment in the interior, and the bottom section of the frame (10) is disposed within the reactor vessel (20), thereby achieving an air environment within the reactor vessel (20). Furthermore, since repairs to the reactor vessel (20) are performed by using the frame (10) while still having the air environment in the interior, this leads to the prevention of contamination and achieves improvements in working conditions such as preventing the generation of dust and reducing decontamination work. Accordingly, repairs can be performed in an air environment without draining the cooling water (2) within the reactor vessel (20), even in a state in which the reactor vessel (20) is covered by the cooling water (2).Type: GrantFiled: December 6, 2010Date of Patent: June 30, 2015Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Takeshi Yamamoto, Kazuhide Yamamoto, Masaya Yamaguchi, Koji Shukutani
