| abstract | (57) [Abstract] [PROBLEMS] To suppress reattachment of a radionuclide to a pipe to which the radionuclide is attached in an operating nuclear power plant. SOLUTION: In a primary system piping of a nuclear power plant, a portion through which a coolant containing a radionuclide is passed and a portion where the dose is increased is cut (step S 2) Then, after connecting the decontamination device and the device for collecting the radioactive waste liquid generated by the decontamination (step S3), the inner surface of the pipe is decontaminated (steps S4, 5). Then, a heating device is installed in the pipe (step S6), and oxygen is added to 0.1 % Or more by heating in the gas phase containing 1% or more To form a dense oxide film of 100 nm (step S7). After removing the heating device and the radioactive liquid waste recovery device (steps S8, 9), the piping is restored (step S1). 0). This makes it possible to prevent the coolant containing the radionuclide from coming into direct contact with the metal surface of the pipe, and to prevent the radionuclide from adhering to the surface after reuse. |
