1 Management of Decommissioning Waste Dipl.-Ing. Jörg Viermann GNS Gesellschaft für Nuklear-Service mbh July 2009 Karlsruhe, Germany, 1

2 Introduction Decontamination Solid Mixed Waste: Suitable for Incineration Not Suitable for Incineration Metal Components (with negligible activation) Irradiated Coponents Ion Exchange Resins (from decontamination) Other Liquids Oil, Organic Solvents Aqueous Solutions July 2009 Karlsruhe, Germany, 2

3 Introduction What is intended by treatment - Volume reduction - Product suitable for storage and disposal (Acceptance Criteria of Storage Facilities and Repository), solid product no free liquid chemically stable product, no chemical reactions (e. g. fouling and fermentation) which could result in gas generation - Additional product quality features (stability against leaching, Thermal stability), which could lead to higher activity limits for the repository July 2009 Karlsruhe, Germany, 3

4 Decontamination Different Methods - Chemical Decontamination - Electropolishing - Water Jet - Blasting Mechanical processes with minimum erosion of material Processes with erosion of material July 2009 Karlsruhe, Germany, 4
