Advances in Technologies for the Treatment of Low and Intermediate Level Radioactive Liquid Wastes

This report describes a wide spectrum of treatment processes of both aqueous and organic radioactive wastes. It briefly covers upgraded traditional and well proven processes such as chemical precipitation, ion exchange and evaporation, and focuses on rather new membrane and electrochemical processes and combinations of these processes. Methods based on the use of biological processes for the treatment of liquid radioactive wastes are described in this report for the first time. It also describes both advantages and disadvantages of the technologies mentioned. Contents: 1. Introduction; 2. Large scale applications of liquid waste treatment technologies; 3. Advances in technologies for the treatment of aqueous wastes; 4. Advances in technologies for the treatment of organic wastes; 5. Future trends in process development; Conclusions.
