Résumé

The current general principles for the protection of the French Nuclear Power Plants against flooding of external origin are defined int the French Basic Safety Rule I.2.e. The partial flooding of "Le Blayais" Nuclear Power Plant in 1999 has called into question the design bases used for the protection against external flooding and the existing measures, especially the warning systems, the site protection measures, the protection of safety-related equipments, the procedures and the emergency organization. Following this event, the protection of the French Nuclear Power Plants against external flooding has been completely reassessed to ensure that the installations would be effectively protected. As a result, numerous additional protection provisions have been implemented on all the French Nuclear Pants.
