METHOD OF PROCESSING OF RADIOACTIVE EFFLUENT Russian patent published in 2006 - IPC G21F9/06 G21F9/20 

FIELD: nuclear engineering; methods of processing of radioactive effluent.

SUBSTANCE: the invention is pertaining to the field of nuclear engineering, in particular, to the methods of processing of radioactive effluent. The method of processing of the radioactive effluent containing radionuclides in the ionic and colloid forms and ballast components of the mineral and organic nature in the soluted and suspended states provides, that the organic components of the radioactive effluent are oxidized up to a gaseous state, and the mineral ionic components and radionuclides are transformed in a suspended state in the form of hydroxides of metals by feeding of the ozone waste. A stream of the oxygenated waste is separated for a thickened slurry and a liquid phase, using the selective sorbents conduct an afterpurification of the liquid phase from the radionuclides, which have remained in the ionic form. The produced slime and the spent sorbents are transformed into the solid form and sent for a long -term storage. Before treatment with ozone the stream of the radioactive effluent is purified from the suspended particles using its percolation through a mesh filtering material, and before an afterpurification of the liquid phase with the help of the selective sorbents conduct a membrane microstraining with separation from the liquid phase of radionuclides in the colloid form, which are sent back in the stream of the radioactive effluent after injection in it of ozone. The technical effect of the invention consist in an improved purification of the radioactive effluent from radionuclides.

EFFECT: the invention ensures an improved purification of the radioactive effluent from radionuclides.
