DEVELOPMENT OF THE PROCESS REGIME FOR CEMENTING SALT CONCENTRATES FROM THE VOLGODONSK NUCLEAR POWER PLANT

摘要

The results of work on the development of the process regime for cementing salt concentrates from the Volgodonsk nuclear power plant are presented. Experiments on model and real bottoms residues from liquid-wastes storage tanks show that additionally concentrating the wastes and regulating the alkalinity can yield cement compounds with dry residue content up to 30% percent. Portland and slag portland cement can be used as the binding material. When the conditions which have been determined are met, the quality of the cement compounds formed meets all normative requirements. The recommended process regime has been implemented in the cementing facility at the Volgodonsk nuclear power plant.
