METHOD OF ORGANIC LIQUID RADIOACTIVE WASTE RECYCLING Russian patent published in 2018 - IPC G21F9/16 

FIELD: environmental protection.

SUBSTANCE: invention relates to the field of environmental protection, in particular to the processes of curing organic LRW. Method for curing organic liquid radioactive waste (LRW) consists in combining LRW with a hardener containing paraffin, heating the resulting mixture and maintaining it until the hardener enters the liquid state and dissolves the LRW in it, cooling the mixture. Amount of LRW in the mixture does not exceed 60 % by weight, and the hardener contains stearic acid, paraffin and ceresin with the following ratio of components, % by weight: stearic acid 60–90, paraffin 5–20, ceresin 5–20.

EFFECT: invention allows to expand the list of condensed LRW, reduce the volume of solidified waste, eliminate the need to store LRW at the sites of their formation and transportation.
