Abstract
This research is devoted to the development of simulants of liquid radioactive waste (LRW), which are necessary for methodical testing of technologies to convert LRW into a non-flowing state. The main goal is to eliminate direct handling of radioactive LRW by personnel during the testing of various technological procedures. The paper presents the results of studies on the essential basic physicochemical properties of LRW generated during the operation and decommissioning of the BN-350 reactor facility, to determine the main requirements for simulant solutions. Additionally, a methodology for preparing different types of LRW simulants is described, aimed at selecting sorbents and optimizing mixing and conditioning technologies.
