As one of effective uses of the JMTR, JAEA has a plan to produce Mo by (n,) method, a parent nuclide of Tc. In case of Japan, the supplying of Mo depends only on imports from foreign countries, the R&D on production method of Mo-Tc has been performed with foreign countries and Japanese industrial users under the cooperation programs. The main R&D items for the production are (1) Fabrication of irradiation target such as the sintered MoO pellets, (2) Separation and concentration of Tc by the solvent extraction from Mo solution, (3) Examination of Tc solution for a medicine, and (4) Mo recycling from Mo generator and solution. Especially, it is important to establish the separation and extraction methods in the item (2) and the experiments and information exchanges in some methods have been carried out under the international cooperation. In this paper, the status of the R&D is introduced for the production of Mo-Tc.
