⁹⁹Mo is the parent nuclide of ^99mTc used for medical diagnostic. The ⁹⁹Mo is produced by the fission method using the fission of uranium. However, the fission method requires a large investment in terms of nuclear regulation and nuclear non-proliferation. Therefore, in Japan, domestic production by the activation method using the neutron capture reaction of ⁹⁸Mo is desired. In this study, R&D of ⁹⁹Mo/^99mTc production by the activation method using PWRs was conducted. In this presentation, we report on the conceptual design of a dissolution treatment system for irradiation targets and a MoO₃ recycling system using spent Mo solution was conducted. In addition, the cost of ^99mTc production was evaluated and further study issues for realization are reported.
