Hydrodynamic-numerical study on the evaluation of flood hazards for power plants

Efficient and adequate protection against flood hazards of nuclear power plants are regulated in the German standards KTA 2207. For this purpose a reliable description of flow pattern in the real system in case of a possible flooding is necessary. Using hydrodynamic-numerical models allow describe spatial and temporal sections of a real system. Today state-of-the-art is the use of two-dimensional models. The hydrodynamic-numerical modeling is of main importance for the design of flood protection measures. The authors demonstrate the use of hydrodynamic-numerical models for the case of storm flood protection including dike break hazards for nuclear power plants in tidal estuaries.
