Zusammenfassung:The present invention relates to a method for refurbishing an atomic fuel assembly storage rack the partitions (10) of which include a layer (14) of neutron-absorbing material between a wall (16) and a more or less rectangular piece of sheet metal (18) welded onto said wall. In this method the sheet metal is cut along each of the four sides. Once the short sides of sheet metal (18) have been cut by cutting the welding spots or by cutting it into sections the long sides are cut using a cutting head (20) that includes one to four blade-blade support assemblies (22) or one to four blades. Each blade (24) and blade support (26) is either fixed or movable.
