The present invention relates to a physical decontamination device for a steam generator, and a physical decontamination method. The physical decontamination method includes: a blast mixing step of mixing compressed air and a stainless steel blast supplied from a compression container; an injection step of injecting the stainless steel blast and the compressed air mixed in the blast mixing step to a heat pipe of an evaporator and a water room; and a discharging step of discharging the compressed air, the stainless steel blast, and a radiative attached material separated from the water room and the heat pipe in the injection step. According to the present invention, costs can be reduced in comparison with a chemical decontamination method, and a decontamination process can be safely and simply performed. |
