Assessment of High Wind and External Flooding (Excluding Tsunami) Hazards in Site Evaluation for Nuclear Installations

In recent years, significant experience has been gained on the effects of high wind and flooding on nuclear installations worldwide. These phenomena may simultaneously affect all the structures, systems and components important to safety at a nuclear installation site. By detailing the methodologies and providing case studies for the evaluation of meteorological and hydrological hazards, this publication supports IAEA Safety Standards Series No. SSG- 18, Meteorological and Hydrological Hazards in Site Evaluation for Nuclear Installations. In the first part of the publication, wind hazards relating to tropical cyclones, tornadoes, extratropical, thunderstorm and wind-borne debris are discussed. The second part covers external flooding hazards (excluding tsunamis) relating to wind induced coastal flooding, wind generated waves on rivers, extreme precipitation and run-off event floods due to sudden release of impounded water.
