Keywords: CONDITIONING OF LIQUID RADIOACTIVE WASTE, BARRIER STORAGE, ALKALINE CEMENT, MODIFYING ADDITIVES, STRENGTH, LEACHING, FROST RESISTANCE, COMPOUND The object of the study is the methods of complex sorption of radionuclides or their imitators from solutions imitating RRV of different composition and nature and immobilization of RRV The subject of the study is the scientific principles of air conditioning of nuclear power plant of Ukraine to ensure long-term disposal safety The aim of the study is to establish the possibility of immobilizing dry radioactive waste based on ferrocyanide copper sorbent complexes with alkaline activated cements. To achieve the goal of the work, it is planned to solve the following tasks, namely, to optimize alkaline activated cement with the addition of magnetite, zeolite and dry radioactive waste based on copper ferrocyanide with the determination of the main properties of the compound; determining the rate of leaching depending on the term (chemical stability of compounds); research on frost resistance of compounds; methods of complex sorption of radionuclides or their imitators from solutions imitating RRV of different composition. Research methods are based on the use of well-known and modern methods, namely analytical, physical-mechanical and chemical. The result of the work was: - an analysis of effective methods of mobilizing the formed solid residue, including through the use of geopolymer concrete, was carried out, namely: -- relevance of extracting residual concentrations of radionuclides and new approaches to their solution; -- description of geocements; -- studies of the possibility of immobilization of dry radioactive waste based on copper ferrocyanide with alkali-activated cements were carried out. -- patterns of sorption and research and application of new nanocomposite sorbents - published 2 scientific articles, 1 theses, received 1 patent of Ukraine.
