For the primary packagelocated near to the impacted corner., this configuration appears more severe than the case of a ″fall ona flat surface″ or a ″fall on an edge″.Figure 11.8.1Installation of the drop-test demonstrator (package B5.2 - CEA/CESTA TestCentre - Gironde)The fall height of 6 m 189 corresponds to the maximum handling height in of the disposal packagesduring emplacement in the disposal cells.189 The fall height is defined as the distance at the start of the fall between the point of impact (lower corner of the cover) and the ground.DOSSIER 2005 ARGILE -ARCHITECTURE AND MANAGEMENT OF A GEOLOGICAL DISPOSAL SYSTEM478/495
