The report covers outline of facilities, treatment and management of radioactive wastes, decommissioning activities, and related R&D activities. In FY2006 radioactive wastes generated mainly from R&D activities in NSRI were treated safely. They were 393m of combustible solid wastes, 152m of noncombustible solid wastes and 493m of liquid wastes. 1,596 waste packages (in 200L-drum equivalent) were generated and totally 134,466 drums were stored as of the end of FY2006. Decommissioning activities were carried out for the JAEA's Reprocessing Test Facility and the Ceramic Fuel Laboratory. As for the R&D activities, studies were conducted on radiochemical waste analyses, clearance, decommissioning technologies and waste management.
