France getting ready for a nuclear accident- part 1

France prépare with the conséquences of an accident of the Tchernobyl type on its ground the WORLD | 20.02.08 | 12h23 Put • à day 20.02.08 | 12h31 thirty years rès après the accident nucléaire of Three Mile Island (the United States, 1979), more than twenty après the explosion of the réactor nº4 of Tchernobyl (Ukraine, 1986), France faces a taboo. It outlines "doctrines" in order to préparer à gérer the conséquences of a catastrophe nucléaire on its ground. In the next days, the Prime Minister will be recipient of a letter of directing Comité for the management of the post-accidental phase of a situation urgently radiological (Codirpa) présentant éléments of réflexion likely to found these doctrines. This mail is the fruit of work carried out by Autorité of sÃ"reté nucléaire (ASN) in bond with services and agencies of the State, the opérateurs nucléaires and certain associative actors, à the continuation of a interministérielle directive of April 2005. It témoigne of a radical change in the façon whose autorités consider the aléa nucléaire. During décennies, they are montrées obsédées by the sÃ"reté, insistent on the mécanisms of défense and of the statistics reassuring, the accident having only one chance on a million to occur, ensured one fréquemment. They are placed désormais from the point of view où it would occur indeed, with environmental and medical conséquences of means and long term. "Until à présent, the texts géraient the emergency phase of an accident, until à the end of the radioactive rejections, which gives per annum place à ten exercises, témoigne Jean-Luc Lachaume, director général assistant of the ASN. The post-accidental one, it is to explore what occurs then: how to return à a livable situation, if as well is as it is it, in the zones touchées." To project itself in this situation, Codirpa has imaginé two scénarios †"rupture of tube of vapor générator, fusion partial of the cÅ"ur of the réactor †"including/understanding rejections respectively of an hour and a journée. Is it or not necessary to authorize the return of the populations in the territories contaminés, and so yes à which échéance? How to organize their medical follow-up, gérer déchets, to dimension the compensations? A mass of interrogations is née of these exercises spéculatifs, led in working groups spécialisés. In décembre 2007, a séminaire allowed synthétiser these contributions, and to measure the way which remains à to traverse. For example, "the méthodology remains à to définir on the évaluation of the amount reçue by the population, notes Mr. Lachaume. It is necessary to introduce a scientific débat, à cold, on this point controversé." Concrètement: décontaminer the houses with the jet, to prévenir the incrustation of the radionucléides, won't it induce pollution in the réseaux ones of water? In would the agricultural zones, be necessary to harvest to concentrate the radioactivité and of débarrasser, or to seek its dilution? In 2008, Codirpa will begin à to give instructions to the préfets, to organize new exercises of crisis to test the ébauche de"doctrine", to engage of the discussions with the mediums associative, éducatif, médical and médiatic. Isn't it inquiétant of être still in the medium of the gué? "One knows well gérer the première accidental phase, ensures Jean-Luc Lachaume. One would be able to réagir well in the event of longer crisis." "One can modéliser, to calculate; from all façon, nothing will occur like prévu ", estimates Monique Sené, of the Grouping of the scientists for information on the énergie nucléaire, which took share with work of Codirpa. The physician greets the effort of the State to fill her gaps, but estimates that one of the priorités consists à to associate the population. Fine expert of the situation in Ukraine and Biélorussie, touchées with the first chief by the radiological cloud of Tchernobyl, Jean-Claude Autret, of Association for the contrÃ' it of the radioactivité in the West, has to him also participé in Codirpa. "One works on accidents très minorés by report/ratio à Tchernobyl, reassuring for the autorités", regrets it, noting that the field of research is "énorme". He félicite however of the change of mentalité within the ASN, so much "he is hard of appréhender the sacrifice of a territory for several siècles, even of the millénaires". Hervé Morin
