A method for removal of hydrogenated carbon deposits from the walls of fusion reactors with carbon divertors is presented. The method is based on interaction of neutral oxygen atoms with deposits at elevated temperatures typically found in such fusion reactors. The source of neutral oxygen atoms is oxygen plasma created with electrodeless high frequency discharges. The density of oxygen atoms in such plasma may approach 1022 m–3 making such discharges suitable for removal of deposits in huge systems like tokamaks.
