An indispensable factor of a nuclear power station from planning to putting into operation is environmental evaluation and accident emergency. In a conventional coastal nuclear power plant, upon occurrence of an accident, radionuclide diffuses inland in the atmosphere, and the dry settlement process thereof has been sufficiently studied. Wind tunnel testing has proven to be practical and effective. Under the condition of an island nuclear power station, radioactive aerosol after an accident is influenced by sea wind, and due to different sedimentation mechanisms and laws of the radioactive nuclide aerosol on the surface of sea and land, the radioactive aerosol spreads to inland across the sea surface, so that the influence range of the radioactive aerosols is different from that of coastal nuclear power stations. Therefore, the research on the dispersion and sedimentation of aerosol between gas and liquid phases on the ocean surface is imperative. In order to study the transport and dry settlement of aerosol on the ocean surface, simulation of sea waves with different wavelengths, wave heights and wave speeds needs to be realized.
