Annual report for FY2021 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, 2021 to March 31, 2022. With regard to the technology development on reprocessing of spent nuclear fuels, Tokai Reprocessing Plant upgraded its binding equipment as a countermeasure for the glass melter shutdown that had occurred at Tokai Vitrification Facility in July 2019. The vitrification process was resumed in August 2021, and 13 vitrified waste packages were produced. As technology development pertaining to process of radioactive wastes, activities were carried out according to the annual plan. In Nuclear Fuel Cycle Engineering Laboratories, 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.
