In April 2020, JAEA has been introduced Physical Protection Corrective Action Program (PPCAP) with full-scale. It was needed to introduce unified operation for six sites with different business scales, and headquarters developed the common guideline. There was an impression that physical protection activities were carried out by a limited number of employees. Therefore, a problem was to root and activate PPCAP activities among all employees in order to make them effective. Five activities were implemented to solve this problem. As a result, more than 3,700 condition reports (CR) have been collected for 4 years. This paper reports on the activities related to the PPCAP that have been implemented at JAEA.

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.

The absorption, transport and accumulation of cadmium (Cd) in rice were analyzed quantitatively using the positron-emitting tracer imaging system (PETIS). We developed a method to produce Cd tracer and obtained serial images of Cd distribution in intact rice plants at vegetative stage and grain-filling stage using PETIS. The results suggest that xylem-to-phloem transfer is a pivotal process on the route from the soil to the grains and the nodes are the most likely organ where the transfer takes place.
