The analysis of the major problems encountered in management of liquid radioactive waste containing seawater has been considered. The sources of such wastes have been examined. In particular, the authors’ experience is concerned with removal of long-lived radionuclides of cesium and strontium by sorption methods from LRW of salinity higher than 1 g / l). The paper describes the most commonly used sorbents for cesium removal and their shortcomings. The example demonstrates application of the sorption-reagent material B-C – 5 in strontium extracting: the material works efficiently not only in seawater but also at the concentrate salinity about 60 g/l. that for this material. The characteristic sorption-reagent mechanism of strontium removal from the solutions containing sulfate ions was experimentally corroborated and found similar to earlier studied amorphous barium silicate. The advantage of these systems consists in high selectivity with respect to strontium in solutions containing calcium.
