Development and testing of an electrochemical cutting process for dismantling activated steel components
Electrochemical decontamination is of great importance in the decommissioning works at KRB A. By this method the metal surface layer is removed by a galvanic process in an electrolytic solution. Using the same principle, it is also possible to remove material locally (ECM-technique). Many advantages of this method suggested that it could be used for cutting activated steel during the decommissioning of nuclear power plants. In the framework of this research, experiments were performed using non-active material from a reactor pressure vessel. The essential results demonstrated which procedures and cathodes would be suitable for high cutting velocities, and how much sludge (waste) would be produced in the electrolyte.
