JMTR has a plan to produce Mo, which is the parent nuclide of radiopharmaceutical Tc, by (n,) method. The cooperation experiments for Mo adsorption and Tc elution with the Poly-Zirconium Compound (PZC) and the Molybdate Zirconium Gel (Zr-gel) methods were carried out at Kazakhstan National Nuclear Energy Center (NNC) in October, 2009. The Mo adsorption capability was the same level as reference data, however the Tc elution capability with PZC was lower than reference data in this test. Therefore, re-experiments of Mo adsorption and Tc elution with both methods were carried out at NNC. As a result, the Mo adsorption and Tc elution capabilities were obtained as the same levels as reference data. Additionally, Tc solution was high purity by the elution method connected with alumina column.

Japan Materials Testing Reactor (JMTR) of the Japan Atomic Energy Agency (JAEA) has a plan to produce Mo, which is the parent nuclide of radiopharmaceutical Tc, by (n,) method. The Mo adsorption and Tc elution characteristics of molybdenum adsorbents should be evaluated since the specific activity of Mo obtained by (n,) method is low. Therefore, Mo adsorption and Tc elution tests with molybdenum adsorbents for the (n,) method such as poly-zirconium compound (PZC) and molybdate zirconium gel were carried out under cooperation with the Kazakhstan National Nuclear Energy Center (NNC). As a result, the Mo adsorption performance of the adsorbents was the same level as conventional data, whereas the Tc elution performance of the adsorbents was lower than conventional data. The Mo adsorption and Tc elution performance will be investigated again in future.

(n,) method has an advantage of easy manufacturing process and low radioactive wastes generation. However, the low radioactivity concentration of Tc is remaining as an issue. Therefore, the Poly zirconium compound (PZC) and the Mo-Zr gel were developed as Mo absorbent in Japan and Kazakhstan. Then, comparison tests and information exchange were carried out for obtaining specific comparison data of PZC and Mo-Zr gel. We were able to obtain specific comparison data of PZC and Mo-Zr gel from these experiments.
