METHOD FOR NEUTRALIZING SLIGHTLY MINERALIZED LOW-ACTIVITY WASTES IN FIELD CONDITIONS

摘要

FIELD: neutralizing liquid radioactive wastes by membrane-sorption methods. SUBSTANCE: method includes decontamination of slightly mineralized low-activity liquid wastes with aid of mechanical filters and ultrafilters, their demineralization on reverse-osmosis filters, and additional passing through ion-exchange filters. Liquid radioactive concentrates produced in the process are additionally concentrated by evaporation with aid of rotary vacuum film concentrator until they are saturated with salts and solidified by introducing them in Portland blast-furnace cement. EFFECT: reduced volume of solid concentrates without impairing their quality and degree of decontamination.
