[en] This National Guide provides basic explanations and methods to assist in drawing up a local plan for the emergency phase way-out, subsequent to a nuclear accident of moderate magnitude causing short-term (under 24 hours) radioactive release, which could possibly occur in France. The accident situations considered in this Guide have little likelihood of arising and are representative of environmental contamination accidents that might occur at French nuclear facilities covered by a special intervention plan (plan particulier d'intervention, PPI). Such accidents may cause environmental contamination warranting action for post-accident impact management within a range of ten to fifty kilometres from the accident site. To provide some perspective, the accidents considered here would be classified Levels 3, 4 or 5 (incidents or accidents causing release into the environment) on the INES scale customarily used to help the public and media to immediately understand the severity of an incident or accident in the nuclear field. This Guide was drawn up subsequently to the work carried out by the Steering Committee on Post- Accident Phase Management in the Event of a Nuclear Accident or Radiological Emergency Situation (CODIRPA), instituted by the French Nuclear Safety Authority (ASN) in June 2005, and in charge of setting out the basic principles underlying the management of nuclear post-accident situations. This version of the Guide shall be updated on the basis of the operating experience feedback received on its use. The Guide is a planning tool, intended for the Prefectures of department where a basic nuclear facility PPI has been instituted. Its purpose is to enable Prefects to plan and effectively conduct preparedness measures at the local level with the aim of winding down the emergency phase, actively involving all of the relevant actors for this purpose. The exit period from the emergency phase is defined as extending approximately one week from the end of the accidental release. The local emergency phase exit plan is intended as the final chapter in the Special Intervention Plan (PPI) for each relevant nuclear facility, paving the way toward managing a situation no longer classified as an emergency, but rather in a medium- to long-term management focus. How to Use This Guide: The Guide is divided into three parts: - The first sets out the local emergency way-out drafting process to be used by the local actors in charge of handling the event. This process consists of a number of stages, through which the preparedness work at the local level is structured. This Part of the document identifies the measure and tasks for which each actor is responsible, referring back to the strategies to be developed; - The second summarises the doctrine set out by CODIRPA, which suggests strategies based upon the development of a post-accident zoning policy and the implementation of some twenty action points during the first week after an accidental release has ended; - The third section of the Guide offers examples of action and task reference sheets, in order to facilitate the task for local actors. It also provides reference sheets for the public, on what characterises a post-accident situation and examples of messages to be used during emergency phase way-out and during the first days subsequent to a possible accident
