Abstract

Since the 2011 Fukushima Daiishi nuclear disaster, the security of nuclear facilities has become an important topic in both the scientific community and the general public. The study and assessment of natural hazards is an integral aspect in the process of assessing the safety of a nuclear site or installation. While there are assessments for individual installations all over Europe there is no compilation that allows for easy comparison between the individual design bases or for comparison with established hazard models. The research therefore focuses on the compilation of a consistent data basis for nuclear power plants situated in the European Union and Switzerland with a focus on the design bases for the natural hazards flood and earthquake. To achieve this goal the available reports on country and individual installation level composed within the frame of the European Nuclear Safety Regulators Group stress test of 2011 were compiled and condensed. Due to limitations of the stress test reports as the primary source the criterion of consistency was not achieved. An additional analysis performed by comparing acceleration values of an well established seismic hazard model to the gathered information was of limited significance.
