Acting in emergency and post-accident situations The emergency and contingency plans require intervention by many players, whose respective roles and duties must be clearly identified, as must the way they interact, to ensure correct coordination. The organisation of each of the players involved in the State’s response to a radiological emergency situation, and the way they interact, are essential to the correct management of this type of situation. The roles and organisation of ASN in an emergency situation are thus precisely defined. The coordination with the international authorities is also essential, both bilaterally and internationally. 2.1 Organising to handle four essential duties 2.1.1 ASN roles and duties In an emergency situation, the responsibilities of ASN, with the support of IRSN, are as follows: ཛྷ ཛྷ check the steps taken by the licensee and ensure that they are pertinent; ཛྷ ཛྷ advise the authorities on population protection measures; ཛྷ ཛྷ take part in the dissemination of information to the population and media; ཛྷ ཛྷ act as Competent Authority within the framework of the international Conventions on Early Notification and Assistance. Checking the steps taken by the licensee As in a normal situation, ASN exercises its roles as the regulatory authority in an accident situation. In this particular context, ASN ensures that the licensee exercises in full its responsibility for keeping the accident under control, mitigating the consequences, and rapidly and regularly informing the public authorities. It draws on IRSN’s expertise and assessments and can at any time ask the licensee to perform appraisals and take the necessary actions, without however taking the place of the licensee in the technical operations. Advising the département and zone Prefects and the Government The decision by the Prefect concerning the general public protection measures to be taken in radiological emergency and post-accident situations depends on the actual or foreseeable consequences of the accident around the site. The law states that it is up to ASN to make recommendations to the Prefect and the Government, incorporating the analysis carried out by IRSN. This analysis covers both a diagnosis of the situation (understanding of the situation of the installation affected, analysis of the consequences for humans and the environment) and a prognosis (assessment of possible developments, notably radioactive releases). These recommendations more specifically concern the steps to be taken to protect the population in the emergency and post-accident phases.
