For the decommissioning of nuclear power plants Abrasive Waterjet (AWJ) cutting was already used successfully in dismantling activities. High contaminated materials are normally cut by AWJ with remote controlled handling systems. However, in non-or low contaminated environments a mobile and flexible cutting system will become more important for simple cutting applications. A first hand-controlled Abrasive Water Suspension Jet system was developed and successfully tested at the Waterjet Laboratory Hannover. Based on these experiences a new mobile and flexible cutting system for injection jets as well as suspension jets was conceived and built. Safety requirements and ergonomic aspects of the human-machine interface have influenced the advanced conception. The developed AWJ cutting system and the results of first successful tests will be presented.
