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.

In order to maintain transparency in the peaceful use of nuclear materials in Japan, it is important to appropriately respond to safeguards activities conducted by the IAEA/Japan. Failure to respond appropriately 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 by Japan. In order to strengthen activities to appropriately respond to safeguards activities, JAEA has started (I) education on safeguards for all employees directly employed by JAEA, (II) lectures, (III) case studies, and (IV) standardization of procedures related to safeguards response since FY2020, following the methods used to foster nuclear security culture in the past. This report describes these specific activities.

In the consultancy meeting "Safeguards Guidelines for post-accident facilities and associated waste management facilities" held in IAEA, decommissioning activities, and the relevant safeguards activities in TRP/PCDF are reported. In general, the facility after accident with access limitation, operator decides to conduct decommissioning. Therefore, our report regarding the decommissioning plan and the relevant safeguards activities are very helpful to be considered. The nuclear material remove and waste management (storage/treatment) are essential work in the normal accessible facility as well as post-accident facility. Otherwise, in the case of post accident facility, alternative safeguards measures is required according to the access situation because normal safeguards activities might not be taken appropriately. In this report, we would present that outline of decommissioning plan in the TRP/PCDF and the relevant safeguards and nuclear material accountancy.
