日本原子力研究開発機構では保障措置対応の適切性確保及び維持に向け、2020年度から全役職員を対象とした教育や関係者対象の講演会や事例研究など様々な取組みを段階的に開始・継続しており、その全体概要は第43回日本核物質管理学会にて報告した。本報告では、2022年度より保障措置関係者を対象に開始した事例研究について、全体概要、具体的事例と解説、及び受講者アンケートの評価結果を踏まえた効果について紹介する。

To maintain transparency in the use of nuclear materials in Japan, it is important for operators to appropriately respond to safeguards activities conducted by the IAEA/Japan. Failure to appropriately respond to these activities could have significant impacts, such as raising suspicion from the international community about the misuse of nuclear materials by not only the operators but also Japan. To appropriately respond to safeguards activities, JAEA has conducted some activities such as education on safeguards for all employees and case study activities for the employees engaged in responding to safeguards activities. This paper focused on case study activities that started in FY2022. In FY2022, we created documents based on scenarios with problems in safeguards responses in order to promote understanding among participants. We also conducted a questionnaire survey for participants, and we evaluated the result of the questionnaire. The evaluation results showed that the case study activities contributed to raising awareness of safeguards responses, although there were improvements. After making improvements, we are conducting these activities again in FY2023. Since case study activities are expected to be effective if carried out continuously, we plan to continue them in combination with other activities.
