This document is announced about the task of Waste Management Section of Waste Management Division in 2003. Mainly, our tasks are fractionating, incinerating and storing low active solid waste and storing high active solid waste. In addition, we are performing required correspondence about management program of low level waste. We had treated and stored waste safely according to our plan. As a result, we have achieved following outcomes. 1. We incinerated the combustible low active solid waste that is generated by the operation of Tokai Reprocessing Plant and the recovery operation of incident at Low Active Liquid Waste Asphalt Solidification Facility. Waste of this recovery operation is stored in the 2nd Low Active Liquid Waste Asphalt Solidification Storage Facility. We incinerated 58 ton of wastes. 2. We stored low active solid waste 854 drums that accommodate 200L. According to the time of Low-Level Waste Treatment Facility completion, we will be able to avoid full of storage. 3. We stored high active solid waste of 148 drums that accommodate 200L. For the time being, there is no problem as regards the administration of storage facility. 4. We carried out the management program of low level solid waste according to plan.

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.
