Development of a high efficiency multi-nuclide aerosol filters for radiation protection during a process of cutting core debris

(1) Plan of this project

Abstract

By using the FCVS technology, we had started to develop a high decontamination air cleaning system to remove multi-nuclides for radiation protection to conduct decommissioning the Fukushima NPP (Fig.17). Development of high efficiency multi-nuclide aerosol filters for radiation protection during a process of cutting core debris at Hokkaido University. A plasma cutter, laser cutter, wire cutter, drilling machine, etc., will be used and will generate aerosols. Therefore, the air cleaning system should be needed for removing core debris. In order to develop an air clean up system for radiation protection during a cutting core debris of the Fukushima Daiichi NPP as a process of their decommissioning, a high efficiency filters will be developed, such as a wet-type aerosol filter, a metal fiber filter and a silver zeolite.
