Times Cited Count:4 Percentile:75.44(Nuclear Science & Technology)Ac is attracting attention as an alpha-emitting medical radioisotope. Since its demand is expected to increase, domestic production of
Ac is required from the viewpoint of Japan's medical research and economic security. To establish the technical bases for the
Ac production, JAEA has evaluated the radioactivity that can be produced in the experimental fast reactor Joyo and designed the concept that upgrades the existing facilities for transporting the irradiated target from Joyo to a neighboring PIE facility rapidly. Efficient
Ac Separation from
Ra irradiated in a fast reactor was studied. Ba and La were used as alternatives to Ra and Ac, respectively. By using DGA resin as an adsorbent, it can be expected that Ra and impurities generated by irradiation will be removed and Ac will be isolated. This study has revealed that Joyo can sufficiently produce
Ac as a raw material for pharmaceuticals.

Times Cited Count:0 Percentile:0.00(Nuclear Science & Technology)Ac is a promising alpha emitter for targeted alpha therapy. However, the current capability of
Ac supply is limited to approximately 63 GBq/y, primarily relying on the natural source of
Th stocked at a few institutes. Therefore, alternative
Ac production methods are highly desired. The research and development of
Ac and its parent nuclide production methods using accelerators and reactors to target
Ra and
Th are actively pursued worldwide. Hence, the authors focused on the
Ra(n,2n)
Ra method using fast neutron spectra as an application of the experimental fast reactor Joyo. This study investigated the status of nuclear data libraries for
Ra, an essential target for
Ac production, and evaluated the impact of different nuclear data libraries on the amount of
Ac produced. Consequently, cross-sections with covariance data were stored in TENDL-2021, JEFF-3.3, and EAF-2010 but not in ENDF or JENDL, the major nuclear data libraries. Furthermore, no consistency occurred among the respective nuclear data, and the
Ra production amount varied.
