Annual report for FY2007 on the activities of Department of Decommissioning And Waste Management (April 1, 2007 - March 31, 2008)

Department of Decommissioning and Waste Management

This reports described the activities of Department of Decommissioning and Waste Management (DDWM) in the period from April 1, 2007 to March 31, 2008. In FY2007 radioactive wastes generated from R&D activities were about 371 m of combustible solid wastes, 152 m of noncombustible solid wastes and 510 m of liquid wastes. After adequate treatment 2,111 waste packages were generated. Two new approaches were conducted for radioactive waste management: development of record keeping system for land burial and a new management system for mid-level radioactive waste packages. Decommissioning activities were carried out as planned for the JAEA's Reprocessing Test Facility, the Ceramic Fuel Laboratory, the Plutonium Laboratory No.2 and the Metallurgical Laboratory. As for the R&D activities, studies were conducted on radiochemical analyses of wastes for land burial, and decommissioning. As for the clearance was applied for approval of nuclide measureing.
