Decontamination of metal components to clearance levels by means of abrasive blasting

Conference:

Abstract

At the decommissioning of nuclear installations, large quantities of metals are produced together with other important amounts of low radioactive wastes. These materials are mostly surface contaminated. Having been used or even only having stayed for some time in a controlled area, marks them as `suspected material`. Costs for treatment and disposal as radioactive wastes of these materials are very high. These very high costs make people look for alternatives in dealing with this kind of wastes. Recycling through melting or through thorough decontamination of metals to generally accepted unconditional clearance levels could be such an alternative. To a larger extent recycling of materials can be considered as a first order ecological action to limit the amounts of wastes to be disposed of, and at the same time reduce the technical and economic problems involved with the management of radioactive wastes and to make economic use of primary material and in this way conserve our natural resources of basic material for future generations. Other evaluations as the environmental impact of recycling compared to non recycling (mining or production of new material) and waste treatment, with the associated risks involved, can also be considered, as well as social and political impacts  More>>

The paper deals with practical examples where in Belgium recycling of material will be carried out using decontamination techniques, and based on the results of different technical and economic evaluations.
