Through the research of Filtered Containment Venting System (FCVS), air purification methods have been developed, such as technologies of scrubbing, metal fiber, silver zeolite and mobility. Using these technologies, we have been studying the further improvement of air purification systems in the nuclear field. In this study, we conducted adsorption experiments using several metal fiber filters and evaluated the effect of the metal fiber wire diameter on the decontamination factor (DF). It was found that metal fibers with fine wires made a significant contribution to the removal of materials with minute particles. By combining the metal fiber technology with the scrubbing technology, a sufficiently huge DF could be achieved on a laboratory scale. Based on these results, we can propose the mobile air purification system.
