LIQUID RADIOACTIVE WASTES PROCESSING DEVICE Russian patent published in 2019 - IPC G21F9/12 C02F9/00 

FIELD: ecology.

SUBSTANCE: invention relates to the nuclear ecology and can be used in the generated during the various nuclear power plants in nuclear power plants and vehicles operation liquid radioactive waste processing. LRW processing plant contains pipelines connected to the shut-off and control valves in accordance with the technological process sequence, LRW source, communicated with the receiving tank, the LRW pretreatment unit, containing the pretreatment unit tank, made in the form of equipped with a stirrer cylindrical sealed container, made with possibility of supplying sorbent, sulfates, flocculant, acids, LRW, and possibility of the supernatant removal, and the filtrate sorption purification unit, consisting of chain of filters, including a filter with the ZF-F sorbent, activated carbon filter and filters with selective CPM, and communicated with the purified liquid accumulator. At that, through the filled with activated carbon and ZF-F sorbent filter, the receiving tank output is communicated with the charging tank, which outputs are communicated with the LRW pretreatment unit tank, which outputs are communicated with the supernatant tank, wherein one of the outputs contains used as the build up filter, for the CPM sorbent separation, and is connected to the LRW pretreatment unit tank additional input. In addition, the filtrate sorption purification output unit is communicated with the first and second accumulation tanks, which outputs are communicated with the brine tank, made with the possibility of communication with the reverse osmosis installation.

EFFECT: invention enables increase in the actual liquid radioactive waste processing efficiency.
