ASN Report 2018

The experience acquired during these many exercises enables ASN personnel to respond more effectively in real emergency situations. 3.2  ̶  Assessing with a view to improvement Evaluation meetings are organised immediately after each exercise in each emergency centre and at ASN a few weeks after the exercise. ASN, along with the other players, endeavours to identify best practices and the areas for improvement brought to light during these exercises. These assessment meetings enable the players to share their experience through a participative approach. They more specifically revealed: ∙ ∙ the importance of having scenarios that were as realistic as possible, in real meteorological conditions and that were technically complex enough to be able to provide useful experience feedback; ∙ ∙ the importance of communication in an emergency situation, in particular to inform the public and foreign authorities as rapidly as possible and avoid the spread of rumours liable to hamper good emergency management, in France and in other countries; ∙ ∙ the importance of providing the decision-makers with a clear view of the radiological consequences in the form of maps: the tool called Criter developed by IRSN gives a representation of the results of environmental radioactivity measurements. In 2018, ASN also brought all the players together to review best practices to improve the response organisation as a whole. In the light of the lessons learned from the emergency exercises and actual emergency situations, ASN decided to study the possibility of adapting the activation of its emergency organisation to the situation actually encountered and the information sharing procedures. In addition, in order to improve the emergency organisation activation time, ASN will define criteria for triggering of the general alert by ASN when it becomes aware of an emergency situation and the licensee of the site concerned is late in triggering the alert.
