Abstract
Outlook for application of amorphous sorbents on the basis of titanyl hydrophosphate to decontaminate liquid radioactive wastes from 137Cs, 134Cs, 90Sr, and 60Co radionuclides with elevated (up to 32 g/l) salt background that corresponds in composition to see water has been shown. Impurities in the form of petroleum derivatives (up to 0.4 g/l) and solid suspensions have no considerable effect on the deactivation and they can be separated together with the waste sorbent from the being cleared solution. The flow chart for the decontamination has been suggested. Heat treatment of the waste sorbent enables conducting immobilization of radionuclides within a solid phase. A variant of deactivation of soils that are polluted by radionuclides has been suggested.
