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.

This annual report summarizes the activities of decommissioning and radioactive waste management in JAEA in the period from April 1, 2018 to March 31, 2019. Decommissioning activities and radioactive waste treatment activities were carried out according to the annual plan. Decommissioning plan of Tokai Vitrification Facility of Tokai Reprocessing Plant (TRP) of Nuclear Fuel Cycle Engineering Laboratories (NCL) was approved by Nuclear Regulation Authority (NRA) in June 2018. Uranium Enrichment Demonstration Plant of Ningyo-toge Environmental Engineering Center (Ningyo-toge), application for approval of decommissioning plan was submitted to NRA in September 2018. The dismantling cost of JAEA facilities were evaluated by DECOST Code, and the results were reflected by Facilities Management Plan. 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 Institute was completed in March, 2019. As technology development pertaining to treatment and radioactive wastes activities were carried out according to the annual plan. Sampling technology of the reactor component and laser cutting technology have been developed towards reactor decommissioning in Fugen Decommissioning Engineering Center. In Ningyo-toge, a uranium measurement technology has been developed to verify the clearance level.
