The article is devoted to the analysis of the modern state of the spent ion-exchange resins (SIER) treatment problem at nuclear power plants where regeneration of resins is not provided. The importance of ion-exchange processes for nuclear-power engineering is determined and the main characteristics of spent resins are given. Technologies suggested for SIER processing and potentially suitable for this purpose are considered including conventional techniques (combustion) and advanced technologies (plasma). The most significant limitations of the SIER treatment methods are accentuated. Special emphasis is placed on the decontamination as the most advisable and prospective treatment method of SIER.
