ABSTRACT:
A boiling water type nuclear fuel rod assembly used in a nuclear reactor and having radioactive scale deposited thereon is taken out of a fuel pool and disposed in a substantially sealed vertical tank, while the scale is still wetted by water. Gas in the tank is heated to a temperature higher than room temperature by the heat of nuclear fission or an electric heater to dry and peel off the scale. A mixture of the scale and water collected in a bottom portion of the tank is sent to a water-scale separator. To rapidly and perfectly remove the scale, after completing the step described above, water is sprayed onto the fuel rod assembly to wet any remaining scale. Then, drying of the scale with hot gas is repeated again.
