Removal technology of oxide film formed on the surface of radioactive mtallic wastes using arc discharge is drawn attention because it does not need cleaning solutions or abrasives as needed in existing chemical cleaning or abrasion methods. We demonstrated the removal of nn-radioactive corrosion products formed on the metallic surface in the same condition of primary water-cooling line and mille scale on carbon steel using a low-pressure arc. The effects of pressure, current and electrode distance on the removal area and weight loss were studied for carbon steel with mille-scale on the surface as a substitute for corrosion products. The arc vaporizes the oxide layer during the treatment, this vapor causing the dust and the film on the electrode. We examined the basic behavior of dust formed in the treatment.
