The Low-Level Radioactive Waste Treatment Technology Development Facility (LWTF) of Tokai Reprocessing Facility has been constructed as a facility for processing low radioactive liquid waste and solid waste generated from the reprocessing facility, and cold tests are being conducted. In this facility, the nitrate waste liquid generated by the treatment of liquid waste was decided to be solidified using borate, but now it is planned to replace it with carbonate waste liquid and then make it cement solid. Therefore, we are proceeding with examination and design for the introduction of equipment. In this report, we conduct a cement kneading and solidification test on a carbonate waste liquid on a real scale (200L drum), and report on the results of examining the influence of the cement solidified body over time and the strength when the waste liquid composition changes.
