Description

Based on experience gained from experiments at the COMIR laboratory and with the installation at the Adennes reactor and on the use of these results for evaluation of calculation methods, this report includes a synthesis of the aspects concerning in particular non-destructive measurement of irradiated fuel in water reactors, fuel assemblies or fuel pins. Following a brief summary of gamma emitting radioactive fission products and, measurement conditions, there is a description of the fuel cooling installation at the Ardennes reactor, including the results obtained with this installation as well as from measurements on the fuel pins. In conclusion, the problem concerning burn-up determination, especially the 134Cs/137Cs method, are discussed

Abstract (French)

A partir de l'experience acquise sur le plan experimental au laboratoire COMIR et avec l'installation implantee a la Centrale Nucleaire des Ardennes et par l'utilisation des resultats pour la qualification des methodes de calcul, on presente dans ce rapport une synthese des aspects qui concernent plus specifiquement les mesures non destructives sur des combustibles irradies de reacteurs a eau, assemblages ou crayons. Apres quelques rappels sur les produits de fission emetteurs gamma et les conditions de mesures, on presente l'appareil en piscine qui a ete realise pour les mesures d'assemblage de la Centrale Nucleaire des Ardennes, et les resultats qui on ete obtenus avec cette installation ainsi que par des mesures sur des crayons. Les problemes de determination des taux de combustion avec en particulier l'application de la methode 134Cs/137Cs sont exposes pour completer cet ensemble
