Regarding Actinium-225, which is one of the medical radioisotopes and has been attracting attention today, we will report on the domestic movement toward domestic production, the research and development plan and progress for production of Actinium-225 using the experimental fast reactor Joyo.
Ac Production; Leveraging the experimental fast reactor JoyoMaeda, Shigetaka

The objectives of this study are the production of Actinium-225 in Japan, and the use of the experimental fast reactor, Joyo. In this feasibility study, the technical bases of the production have been established. This feasibility study shows that the experimental fast reactor Joyo can produce a sufficient amount of Ac-225. This has been confirmed by calculation. The existing refueling and PIE transfer systems with some modifications can quickly transfer irradiated Ra-226 to the neighboring PIE facility. We have completed the concept design for the modifications. The chemical process has been confirmed by the radiochemical examination. In the future, Demonstration tests to demonstrate the production of actinium-225 will be planned and production quantities will be evaluated.
