摘要

The present invention relates to a method of cleaning a zirconium alloy tube used in a nuclear power field and, more specifically, to a method of cleaning a zirconium alloy tube for a sheath pipe of a nuclear power plant in a highly efficient manner. According to the present invention, the method of cleaning a zirconium alloy tube is not excessively required for costs and time by cleaning the tube with a large amount of alkali cleaning agents, can easily treat wasted water, and can reduce costs by performing cleaning under the optimal conditions. A cavitation phenomenon of ultrasonic wave, which is a phenomenon of generating and extinguishing fine bubbles by a pressure of ultrasonic wave when energy of ultrasonic wave is transmitted to a solution, wherein the phenomenon accompanies a high pressure and a high temperature, allows an object to be cleaned in which liquid is stored to be quickly cleaned deeply into the inside of the object to be cleaned by a shock wave, and thus a cleaning using ultrasonic wave and vacuum is more efficient than normal cleaning. In addition, the cleaning effect can be enhanced by removing dissolved gas in the cleaning agent by using vacuum, so about 8 ppm of oxygen is dissolved in general water, and the cavitation can be about five times stronger when the oxygen is reduced down to 0.5 ppm. Finally, as a result of test using vacuum ultrasonic cleaning [40 KHz,1000 W, 80 Torr (1.1 X 10^1 Bar)], 91% more contamination are cleaned in the vacuum ultrasonic cleaning than the general washing, and the cleaning effect is excellent. The optimized cleaning condition based on the result is applied to an industrial site, so the cleaning effect is maximized, and thus the polluted zirconium tube can be economically used.;COPYRIGHT KIPO 2018
