Sažetak
Classification of the operational radioactive waste at Krsko NPP is based on so-called waste streams. Waste streams are usually defined as the waste with roughly constant and unchanging radioactive, mixed or hazardous characteristics. Taking into account different sources of radioactive wastes at Krško NPP, the following six (6) waste streams has been recognized: (1) Evaporator Concentrates (EC) ; (2) Spent Ion Resins (SIR) ; (3) Spent Filters (SF) ; (4) Compressible Waste (CPW) ; (5) Non- compressible waste (NCW) ; and (6) Specific waste (SW). Krško NPP has been started a project on Characterization of mentioned waste streams, recently. The main purpose of the project is determination of key waste parameters needed for further treatment, conditioning and transfer to the Radioactive Waste Management Agency (ARAO) for disposal, as well. Characterization process is being conducted in accordance with recommendations given in Characterization of Radioactive Waste Forms and Packages issued by International Atomic Energy Agency, 1997. It means that radiological, chemical, physical, mechanical, biological and thermal properties of the raw wastes, waste forms and waste packages have been taken into consideration. The presentation deals with the waste streams (i.e. raw wastes, treatment and conditioning technologies, waste forms and containers that are used for interim storage) and classification of the waste packages already stored in Solid Radwaste Storage Facility at Krsko NPP site. The properties of raw wastes, waste forms and waste packages (radiological, chemical, physical, mechanical, biological and thermal) that have been investigating within the project are shortly explained. The main results of the mentioned characterization process are showed and discussed. The particular attention is paid on acceptance criteria for interim storage. Waste Acceptance Criteria for disposal as well as the need for additional treatment and conditioning are shortly discussed.
