Abstract

The mobile modular installation for processing of liquid radioactive waste of complex physic-chemical composition is developed in co-operation of the All-Russian Research Institute of Chemical Technology and a number of research and production organisation. The complex treatment of the solutions is done in a membrane adsorption technology followed by the cementation of formed sediments and slimes. The distinctive feature of the proposed LRW processing scheme is the ability to nearly completely extract the most dangerous radionuclides Cs-137, Co-60 and Sr-90 on the selective inorganic Co-, Ni-,Cu-containing adsorbents at the stage of the initial solution pre-cleaning. The developed scheme on ensures a possibility of reusing purified water according to standard OST V95.823-89 and the minimum quantity of SRW ensuing at the LRW processing.
