METHOD FOR RADIOACTIVE SOLUTIONS HANDLING AFTER DEACTIVATION OF PROTECTION EQUIPMENT SURFACES Russian patent published in 2018 - IPC G21F9/16 

Abstract RU 2643362 C1

FIELD: ecology.

SUBSTANCE: invention can be used for safe and effective treatment of large amount of liquid radioactive waste of different levels of activity. For these radioactive solutions after protective equipment surfaces deactivation, are evaporated with alkaline and acid solutions containing sodium hydroxide, potassium permanganate, oxalic acid and nitric acid to a solid residue, calcinated, the calcinate is mixed with blend components containing titanium, calcium, iron (III), zirconium and manganese (IV) and aluminium oxides in a certain ratio, and fused.

EFFECT: invention allows to lower the melting point of the resulting ceramic.
