FIELD: nuclear power engineering; treatment of wastes from nuclear power plants. SUBSTANCE: liquid radioactive wastes are passed through sorbent placed in filter; sorbent is obtained by pre-filling filter with porous matrix and its processing to produce sorbent in the form of spongy formed block. Liquid radioactive wastes are first passed through central zone of filter and then over peripheral part around it. Spent sorbent is conveyed to storage site together with filter. EFFECT: improved service life of filter; improved environmental situation around nuclear power plant due to dispensing with solidification of spent sorbents prior to conveying them to storage site. 1 dwg
