In this study, the irradiation tests of the high-density MoO pellets and PIEs were carried out with WWR-K for the realization of Mo/Tc production procedure by the (n,) method. High-density MoO pellets were irradiated. After neutron irradiation, the irradiated pellets were carried out PIEs, and the pellets were sound from the results. The irradiated pellets were also dissolved with NaOH solution at 100C. The solution speed of the pellets at 100C was faster than that at 50C and the it was clear that dissolved temperature of pellet was important factor for the solution speed. Mo adsorption/Tc elution tests were carried out with PZC and PTC. It was obtained that the properties of Mo adsorption/Tc elution of these Mo adsorbents was equivalent in previous results. As the these results, the prospects are bright for the realization of Mo production procedure by the (n,) method.
