Keywords: liquid waste, decontamination, evaporation
Abstract: The invention relates to nuclear technology. The method consists of evaporation of liquid waste in evaporators, cooling of condensate of secondary vapor, purification and its desalination through filter. Part of the desalted condensate – the unbalanced water – is concentrated, being repeatedly passed through cooling towers and heat exchanger. Then radionuclides are removed in bypass treatment.

Keywords: liquid waste, decontamination, cesium, strontium, reverse osmosis, distillation
Abstract: Usage: chemical technology, specifically in the nuclear environment, the processing of liquid radioactive waste (LRW) resulting from the operation of various atomic power plants. Stepwise processing of liquid waste, containing cesium and strontium, is conducted in the following sequence:
>Pre-treatment stage: mechanical cleaning, ultrafiltration, microfiltration
>Passing through selective inorganic sorbent, based on ferrocyanide of transitional metal of copper, nickel, cobalt and porous inorganic carrier, then subjected to desalting and concentration using one of the following methods:
1. distillation
2. two-step method: first step: usage of reverse osmosis or electro-demineralization, second step: distillatory or electroosmotic concentration.
