Abstract
The German regulatory body has issued technical documents on methods and data for probabilistic safety assessment, elaborated for a comprehensive integrated safety review of all nuclear power plants in operation. These documents contain, among others, a graded approach for the probabilistic assessment of external flooding. Main aspects are explained such as the underlying probabilistic considerations and the mathematical procedures for the calculation of exceedance frequencies for nuclear power plants at tidal rivers in Germany. Morever, extreme events such as tsunami waves have been investigated.
Kurzfassung
Für die Durchführung umfassender integrierter Sicherheitsüberprüfungen für alle in Betrieb befindlichen deutschen Kernkraftwerke Behörde sind behördliche technische Dokumente über Methoden und Daten für probabilistische Sicherheitsanalysen herausgegeben worden. Diese Dokumente enthalten, unter anderem, einen gestaffelten Ansatz für die probabilistische Analyse im Fall einer Überflutung durch Hochwasser. Die grundsätzlichen Aspekte wie die zu Grunde liegenden probabilistischen Betrachtungen und die mathematischen Prozesse für die Berechnung der Überschreitenswahrscheinlichkeiten des Bemessungshochwassers für Standorte deutsche Kernkraftwerke an Flüssen nahe der Küste werden beschrieben. Außerdem werden die Ergebnisse von Untersuchungen möglicher Tsunamis an der Nordseeküste vorgestellt.
