This paper presents technical and methodological approaches developed by PDC UGR to characterize the removed graphite blocks by gamma-emitting radionuclides during graphite stack dismantlement and to enable their packaging. It overviews the experimental testing of the characterization method and its findings. It also presents container design option allowing to achieve the maximum filling efficiency.
