Recovery of Platinoids from NPP Spent Nuclear Fuel and Outlook for Their Use

For technical and economic reasons, the technology for extracting platinoids from irradiated fuel is a complex problem. The purpose of the present work was to analyze the content of platinoids in the products of the technological scheme used for reprocessing spent fuel, the most called for methods of extracting platinoids, and the outlook for using platinoids. The problem of extracting platinoids cannot be solved apart from the basic technology of recycling fissile materials. The recovery of rhodium and ruthenium must be considered in the context of the appearance of a real demand and palladium from the standpoint of its use in radiochemical enterprises, for example, for immobilization of 129I and/or transplutonium elements, where high elemental purification is not needed.
