Abstract
Summary
This article is devoted to the analysis of experience in using thermodynamic modeling to solve problems related to safe disposal of radioactive waste in Ukraine. It is shown that a number of approaches and models have been developed in Ukraine (models of solid solutions for clay and cement, sorption models, chamber model, etc.), which can be used both to assess the efficiency of EBS components and to assess the geochemical evolution of the geological environment. The possibility of thermodynamic modeling using to take into account physical and chemical interactions in the safety analysis of RAW repositories is also illustrated and the place of this approach in the justification of safety of RW disposal shown is.
