Recycling of copper used in fusion power plants
The ability to recycle end-of-service materials from fusion power plant is beneficial both in terms of the conservation of natural resources and the minimization of the volumes of activated wastes. The presence of silver as a common impurity in copper is a problem but removal of the silver impurity in a separate refining step prior to use of the copper in a fusion plant obviates the problems associated with formation of (108) Ag. Two alternative desilverization processes have been demonstrated; one involving the segregation of silver as AgBr and the other the absorption of Ag ions by ion exchange. The present study demonstrates that conventional electrorefining techniques can be adapted to recover used copper in a single refining stage, with sufficient decontamination to permit its reuse in fusion power plants, or with a second stage, unrestricted release.
