  • Publication number: 20110277304
    Abstract: Both ends of a circulation pipe of a film formation apparatus are connected to a piping of a BWR plant. A chemical including chromium ions and formic acid is injected into a film formation solution flowing in the circulation pipe heated to a temperature within a range from 60° C. to 100° C. Furthermore, a chemical including iron (II) ions and formic acid, hydrogen peroxide, and hydrazine are injected into the circulation pipe. Due to the injection of these chemicals, a film formation solution of pH 7.0 including iron (II) ions, chromium ions, formic acid, hydrogen peroxide, and hydrazine is generated in the circulation pipe. This film formation solution includes hydrazine of, for example, 1000 ppm. The film formation solution is supplied to the piping, thus, a Fe3—xCrxO4 film (here, 0<X?0.1) is formed on the inner surface of the piping. The above method of forming the ferrite film on a structural member (for example, the piping) can be shortened time required to form the ferrite film.

  • Publication number: 20110131799
    Abstract: According to the method for manufacturing electrode sheets, in a first cutting step, an original sheet, including a belt-shaped metal foil and an electrode material coated thereon in a lengthwise direction to form a plurality of coated portions spaced at a predetermined gap, is cut at a location between the coated portions. In a pressing step, the original sheet strips having been cut in the first cutting step are pressed. In this case, the original sheet strips that are pressed by the rolling device are independent from each other. Therefore, the effect produced in rolling of the coated portions remains within each of the original sheet strips. In addition, distortions occurring in the original sheet strips can be prevented from affecting each other and the occurrence of wrinkles can be inhibited.

  • Publication number: 20110030850
    Abstract: A bath containing nickel ions and formic acid is injected into a film-forming aqueous solution flowing in a circulation pipe connected to feed water pipe made of carbon steel in a BWR plant. This film-forming aqueous solution is supplied into the feed water pipe through the circulation pipe, and then, a nickel metal film is formed on an inner surface of the feed water pipe. After the nickel metal film is formed, a film-forming aqueous solution containing iron (II) ions, formic acid, nickel ions, hydrogen peroxide, and hydrazine is supplied to the feed water pipe. A nickel ferrite film is formed on the surface of the nickel metal film in the feed water pipe. Then, the nickel ferrite film is come into contact with water containing dissolved-oxygen at 150° C. or above to transform the nickel metal film into a nickel ferrite film. A thick nickel ferrite film is formed on the inner surface of the feed water pipe. Corrosion of the carbon steel member composing the plant can further reduce.
