Abstract
During the decommissioning of the Fukushima Nuclear Power Plant after severe accident, the process of cutting the core debris (using a laser cutter, wire cutter or drilling machine) will generate a large amount of radioactive aerosol. Therefore, the air cleaning system should be needed to prevent the release of radioactive materials into the environment. For this purpose, an integral filter system including three filter layers has been developed: the wet-type aerosol filter, multi-stage metal fiber filter and the zeolite filter for organic iodine removal. The wet-type filter plays an important role in effective removal the aerosol particles from the venting system and it should be properly investigated. In this study, the behavior of bubble distribution in the two-phase flow of the wet-type filter layer was investigated for the difference of the air injection flow rate.
