In Japan, many facilities are constructed along the seashore and the nuclear power plants which need cooling water are also constructed along the seashore. In addition, spent fuel intermediate storage facilities are planned to be constructed in the Sea of Japan coast area. In pursuing sea salt aerosol-induced corrosion research, it was necessary to perform corrosion tests under a certain set of environmental conditions since corrosion of structures was known to be highly sensitive to environmental factors. To improve the corrosive condition, we considered to use filter. The definition of filter goodness on this study is that the amount of sea salt reduction is large as compared with pressure loss. From this view point, we carried out the filter performance test. From this tests result, we confirmed that our selected filters have good performance.
