Solidification of intermediate-level liquid wastes with the use of inorganic binders

Results of studies are presented using simulators of wastes from nuclear power plants with RBMK (high-boiling channel reactor) and VVER (Water-cooled-water-moderated power reactor) and AST-500. They studied the effect of separate components of the wastes on the strength of the product formed for three types of binders: Portland cement, slag-1, and Portland blast-furnace cement. The permissible amount of components whose presence is discernible was determined. The studies performed showed that by selecting the appropriate binder and conditions for carrying out the process, products with a high salt content and mechanical strength exceeding 100 kgf/cm2 can be obtained
