ALUMINOSILICATE SEDIMENT DISSOLUTION IN LIQUID RADIOACTIVE WASTE STORAGE FACILITIES

The article deals with the extraction of insoluble sediments formed in storage tanks during long-term storage of liquid radioactive waste from spent nuclear fuel reprocessing. Results of a thermodynamic analysis are presented enabling to assess the structure of the precipitation formed and to select most effective modes for thermal and hydrodynamic effects (cavitation technology) produced by liquid medium on eroded sediments. The paper presents the results of studies on the extraction of poorly soluble pulp components from storage tanks using cavitation technology.

Keywords: radioactive waste, waste from spent nuclear fuel reprocessing, cavitation technology, hardly soluble precipitation.
