"Advanced radioactive material removal system by silver zeolite" was adopted in the 2020 to 2023 fiscal year as a project "nuclear-power-industry base strengthening enterprise" of the Ministry of Economy, Trade and Industry. Various system developments and performance tests were carried out in the project such as scrubbing system, metal fiber filter system and silver zeolite system. In this study, adsorption experiments were conducted using multiple metal fiber filters with different wire diameters, and the effect of the wire diameter of the metal fibers on the decontamination Factor (DF) of the particles was evaluated using a scanning electron microscope and so on.
