Safety management and event-based safety culture assessment

The absence of any requirements for safety management in German nuclear regulations resulted in the need to develop regulatory guidance in which the requirements for safety management systems are systematically compiled and was issued in 2004. In this context, also safety culture has to be assessed. For that purpose a single method has been developed on the assumption that root cause analyses of incidents or occurrences in nuclear power plants give indications of deficiencies in safety culture. An example of the application of this method will be shown.
