TRANSPORT OF IRRADIATED FUELS RODS FOR ANALYSIS EXPERIENCE AND NEW DESIGN TN MIL IN PROGRESS

The knowledge of the irradiated fuel rods behavior is crucial in order to improve the performance of nuclear power plants. Therefore, it is necessary to transport either the whole spent fuel assemblies or only parts of them like fuel rods from power plant to specialized laboratories for post irradiation examination. The purpose of this paper is to expose French experience with existing casks (R62, IL 46, IL47), the new package TN 106 under manufacturing and to present a new design called TN MIL, which is being developed according to the IAEA TS-R-1 recommendations.
