Annual report for FY2020 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 Japan Atomic Energy Agency (JAEA) in the period from April 1, 2020 to March 31, 2021. To reduce a risk of storage of high-level radioactive liquid waste, design of the 3rd melter was conducted with considering trouble occurred in 2nd melter operation in July 2019 at Tokai Vitrification Facility of Tokai Reprocessing Plant (TRP) of Nuclear Fuel Cycle Engineering Laboratories (NCL). Decommissioning activities were carried out according to the annual plan. As technology development pertaining to process of radioactive wastes, activities were carried out according to the annual plan. In NCL, technology of immobilization for radioactive waste has been developed to keep the safety. In Ningyo-toge Environmental Engineering Center, a uranium measurement technology, environmental research and decontamination technology has been developed for uranium waste management.
