CONDITIONING OF SOILS AND SILT BOTTOM SEDIMENTS CONTAINING RADIOACTIVE MATERIALS

The paper presents some proposals on the use of radioactively contaminated materials generated from nuclear decommissioning and remediation of radioactively contaminated sites as initial components for radioactive waste immobilization. It presents the results of previous research on the development of processing and conditioning methods for solid radioactive waste present in the form of soils and silt bottom sediments in water bodies . The paper discusses the feasibility of applying certain composition of the initial mixtures and the characteristics of the obtained products, technological parameters of the binding materials synthesis. It overviews the studies on the phase formation under calcination of raw mixtures and hydration of produced materials. Considered are the key technological parameters of the process, the results of grand waste lots processing using a stand installation. Properties of conditioned waste have been studied as well.

Key words: radioactive waste, silt bottom sediments, soils, soil processing, co-processing of radioactive waste.
