Résumé

The analysis of the management of the accidentally radioactive contaminated areas, such as around Chernobyl nuclear power plant, highlights the fact that the current spatial classification methods hardly help in recovering a correct use of the contaminated territory. The cause is mainly to be searched in the traditional construction of risks assessment methods which rested on criteria defined by institutional experts. But these methods are not applicable in practise because not shared by all the stakeholders involved in the management of the contaminated territories. At the opposite of such top-down tentative of management, local efforts, supported by Non Governmental Organization to restore the live in contaminated territories, seem to be more fruitful but greatly limited to the specific areas where they are experimented and also very time and resources consuming.
The aim of the PRIME Project, developed by the French Institute for Radioprotection and Nuclear Safety, is to mix the advantages of both approaches in building a multicriteria decision tool based on the territorial specificities. The criteria of the method will be chosen and weighted with representatives of the stakeholders of a territory (i.e. decision makers, local actors and experts) in order to warrant that all the points of view will be taken into account. This method will also enable the risk managers to choose the appropriate strategy in case of an accident involving radioactive substances. The area chosen for the pilot study is a 50 km (i.e. 31.07 mi) radius territory around the nuclear sites of Tricastin-Pierrelatte in the lower Valley of the Rhône (France). So the essential exploration question of the PRIME project should be whether a multicriteria method can be an appropriate tool to treat the data
and make them visible and accessible for all the stakeholders?
