Based on ocean current numerical forecast in China Seas, high-resolution coast line and bathymetrictopography data of nearshore area, an oceanic radiation consequence analysis system has been established for nuclear power plants. The developed system adopts models used for current forecast, radioactive effluent numerical dispersions and radiological dose assessment. The system can simulate the dispersion path of radioactive effluent in various domestic nuclear power plants, and can make sophisticated three-dimension assessment in the nearshore area of a specific nuclear power plant. The assessment result can provide technical support for decisions on emergency response action. This paper provides an assessment result on an assumed nuclear accident in the Ningde Nuclear Power Plant. The assessment result shows that in the assumed situation, the ocean current in the simulated sea area is slow and semi-diurnal, which heads eastward during falling tide, westward during rising tide. The slow ocean current causes a slow diffusion process, thus high radioactive concentration will be accumulated in the near shore area.
