European Clearinghouse: Report on External Hazard related events at NPPs
External phenomena are a significant source of hazards to nuclear power plant operation, and thus it is important to investigate the existing operational experience in this kind of events. The objective is to determine the adequacy of protection of nuclear power plants against external hazards and the effectiveness of corrective actions, as well as to provide recommendations on how to prevent or mitigate the impact of external phenomena on NPP operation.
IAEA Safety Guide NS-G-1.5 defines external events as "events that originate either off the site or within the boundaries of the site but from sources that are not directly involved in the operational states of the nuclear power plant units, such as fuel depots or areas for the storage of hazardous materials handled during the construction, operation and decommissioning of units located at the same site".
This Summary Report presents the results of a comprehensive study performed by the European Clearinghouse on Operating Experience Feedback of NPP with the support of IRSN and GRS. It addresses both natural origin and man-induced external events, with the exception of the earthquake hazard.
