摘要： PROBLEM TO BE SOLVED: To shorten the treatment time required for discarding the solution used for forming a ferrite film.
SOLUTION: A film forming device is connected to a piping system of a film forming target (S1), and the chemical decontamination to the inner surface of the piping of the piping system is executed (S2). After the completion of decontamination, the temperature of a film forming aqueous solution (an organic acid solution containing iron (II) ions containing an oxidizing agent and a pH control agent) used in the formation of the ferrite film is adjusted (S3), so that the ferrite film is deposited on the inner surface of the piping (S4). The treatment method of the waste liquid after the ferrite film is formed has processes, that is, the process (S6) of injecting the pH control agent (hydrazine) in the waste liquid so that the pH of the waste liquid becomes 6.5 or above, the process (S7) of injecting the oxidizing agent (H
2 O
2 ) in the waste liquid, the process (S8) of precipitating iron (II) ions in the waste liquid as solid particles of a magnetite to remove the solid particles by a filter and the process (S10) of subsequently decomposing the organic acid (formic acid) and pH control agent in the waste liquid using the oxidizing agent and the catalyst.

SOLUTION: When an old shroud 1 is primarily cut within a nuclear reactor pressure vessel 14 and is carried out to a drier separator pool 13, and secondary cutting is performed outside a reactor as a carried-out shroud 2, an aggressive water jet cutting device using alumina as a cutting agent is applied to both a primary cutting device 20 and a secondary cutting device 21 in a similar manner, and a device for collecting secondary products at the time of cutting is also applied to both the devices. Thereby, the radioactive waste quantity can be reduced, generation of rust in the nuclear reactor can be suppressed, and increase in washing work quantity can be controlled, thus reducing a whole work period.

摘要： PROBLEM TO BE SOLVED: To provide an operation method for a nuclear power plant containing a procedure for suppressing radioactive components produced during operation to adhere on the pipes and components and to raise dose rate of pipes and components. SOLUTION: The operation method for nuclear power plant is to positively inject oxidation agent such as hydrogen peroxide at the start up of the nuclear power plant or in the first cycle after decontamination of pipes and components based on the new knowledge that later radioactive adhesion can be suppressed by forming a coating on the surface of pipes and components in an environment where oxidation agent exists at the initiation of operation of the nuclear power plant. In the operation method for nuclear power plant, the injection of reduction agent such as hydrogen used for suppressing oxidation agent such as solved hydrogen peroxide is purposely delayed at the start up. Iron concentration is suppressed low not to disturb the coating production function of the oxidation agent and the iron concentration is raised after forming the coating in the operation method.
