1 RADIOACTIVE WASTE MANAGEMENT PART 2 A RAHMAN RWE NUKEM Ltd (UK) Name, company and chapter
2 Sources of Radioactive Waste Operational activities POCO Decontamination Dismantling Land remediation
3 Management of Radioactive Waste From generation of waste To disposal of waste
4 Hazards in RWM UnmanagedManagedConditioned Disposed Variation of hazards with RWM Hazards
5 Physical States of waste Solids: Contaminated materials, equipment, pipes, cables, concrete, rubbles etc Liquids: Arising from decontamination work, waste treatment plant, water purification system etc. Gases: Arising from decontamination processes, dismantling activities etc.
6 Waste types Primary wastes: contaminated and activated original materials. Secondary wastes: from processing of primary waste, from decontamination and other associated processes.
8 Conditioning objectives Conversion to solid form waste form Suitable for long term storage or disposal
9 Pre-treatment Treatment Conditioning Storage and Disposal Cleared Material (specific) Cleared Material (general) Waste and materials
10 Various types of Treatment Solid waste:(i) Compaction (ii) Incineration Aqueous effluent:(i) Chemical precipitation (ii) Evaporation (iii) Ion exchange Gaseous waste:(i) HEPA filters (ii) Adsorption or chemisorption (iii) Scrubbing (iv) Cryogenic retention
11 Types of Treatment for Solid Waste No compaction, no incineration No compaction, incineration Pre-compaction, no incineration Pre-compaction, incineration
12 Burnable Waste Compactor (Low force Compactor)
