| titleOfInvention | Method of attaching noble metal to carbon steel member of nuclear power plant and method of suppressing attachment of radionuclides to carbon steel members of nuclear power plant |
| abstract | Provided is a method of attaching a noble metal to a carbon steel member of a nuclear power plant, which can reduce the time required for forming a nickel metal film for attaching the noble metal on the carbon steel member. A film forming apparatus is connected to a purification system pipe, which is made of carbon steel, of a BWR plant (S1). A pH buffer solution is injected to obtain the pH 4.0 of the film forming aqueous solution (S4). An aqueous solution of nickel formate is injected into the film forming aqueous solution (S5), and a reducing agent is further injected (S5). A film forming aqueous solution including the pH buffer solution, nickel ions and the reducing agent is supplied into the purification system pipe to form a nickel metal film on the inner surface thereof. After the formic acid and the reducing agent in the film forming aqueous solution are decomposed (S8), injection of platinum ions (S10) and injection of the reducing agent (S11) are carried out, and the aqueous solution including platinum ions and the reducing agent is brought into contact with the surface of the nickel metal film formed on the inner surface of the purification system pipe to attach platinum to the surface of the nickel metal film. |
