METHOD OF CLEANING LIQUID RADIOACTIVE WASTES FROM ORGANIC IMPURITIES Russian patent published in 2016 - IPC G21F9/00

Abstract RU 2597242 C1

FIELD: processing and recycling of waste.

SUBSTANCE: invention relates to means of handling liquid radioactive wastes. Method of processing liquid radioactive wastes (LRW) contains comprises following main steps: feeding initial solution of liquid radioactive wastes, evaporation of liquid radioactive wastes, adjusting pH of initial solution, adding activated pyrolusite to initial solution, stirring obtained suspension, heating suspension, withdrawal of steam released with its subsequent condensation, sampling released gases and their chromatographic analysis, formation of dry residue, as well as cementing of dry residue.

EFFECT: expansion of application and simplification of cleaning process.
