METHOD FOR IMMOBILISING LIQUID RADIOACTIVE WASTE Russian patent published in 2021 - IPC G21F9/16 

FIELD: waste processing.

SUBSTANCE: invention relates to the field of environmental protection, namely to the field of processing of liquid radioactive or chemical waste and isolation thereof from the environment. The method consists in the fact that a radioactive solution is hardened by mixing with a polymer material and then further drying using UHF radiation. The solution hardening and drying process can be performed multiple times. At the final stage, a reagent capable of intensively absorbing UHF radiation is introduced into a portion of the processed solution, and drying is executed until ashing.

EFFECT: provides a possibility of significantly reducing the final volume of solid waste.
