Annual report for FY2015 - 2016 on activities of decommissioning and radioactive waste management

Sector of Nuclear Fuel, Decommissioning and Waste Management Technology Development

This annual report summarizes the activities of decommissioning and radioactive waste management in JAEA in the period from April 1, 2015 to March 31, 2017. Decommissioning activities and radioactive waste treatment activities were carried out according to the annual plan. To reduce a risk of storage of high-level radioactive liquid waste, produced 25 vitrified wastes at Tokai Vitrification Facility of Tokai Reprocessing Plant (TRP) of Nuclear Fuel Cycle Engineering Laboratories (NCL). Radioactive waste generated from R&D activities in JAEA were treated and managed safety. Also, the construction of Oarai Waste Reduction Treatment Facility (OWTF) of Oarai Research and Development Center was carried out. As technology development pertaining to treatment and radioactive wastes activities were carried out according to the annual plan. Laser cutting technology have been developed towards reactor decommissioning in Fugen Decommissioning Engineering Center. In Ningyo-toge Environmental Engineering Center, a uranium measurement technology has been developed to verify the clearance level.
