Since power plants are primarily using seawater as cooling water, they have been severely damaged quite often by various marine organisms inflow in power plants. So, various screen system - bar screen, travelling screen, drum screen and debris filter - have been used as a facility preventing harmful substances into the water intake of power plants. However, it is not enough to prevent too small organisms such as krill shrimp and large mucilages such as jellyfish. Therefore, it is necessary to study the screen system that can prevent harmful substances more efficiently. In the present study, the principal and shape of a air bubble barrier system was proposed as a screen system for preventing harmful substances. Then, analytical studies were carried out to evaluate environmental loading acting on the barrier structure.
