METHOD OF LIQUID RADIOACTIVE WASTES PROCESSING Russian patent published in 2016 - IPC G21F9/18 

FIELD: energy.

SUBSTANCE: invention relates to nuclear power engineering. Method of liquid radioactive wastes processing consists in creation of two reinforced concrete, waterproof pools with depth, equal to fast growing algae height, for example laminaria. In first pool tinted radioactive water is filled, diluted to radiation level, not suppressing algae growth, fast-growing algae are implanted. When algae reaches colour, close to colour of water in pool, algae is removed, dried and incinerated in furnaces, ash is vitrified. Smoke from furnace is passed through water valve. In case of safe radioactivity values exceeding, also is used, as initial radioactive water. In furnace gas is used obtained, for example, from solid household and/or radioactive wastes anaerobic storage bins. In second pool with pure water algae are planted for growth of seedlings, which then is to be implanted in first pool and procedure is repeated.

EFFECT: invention allows to accelerate method of radioactive water elimination, reduce number of operators working for processing and deactivation of radioactive water.
