[en] A preliminary design of the fuel handling machine of the encapsulation plant is presented in this report. In the fuel handling cell the fuel assemblies are handled by the fuel handling machine when the spent nuclear fuel is encapsulated for final disposal. The aim of the preliminary design is to check that the encapsulation plant design is correct and to make the design specification for the further development of the fuel handling machine. The fuel handling machine is capable to handle the fuel assemblies of all plant units of Loviisa and Olkiluoto Nuclear Power Plant. The fuel handling machine is based on the bridge crane, which is moving along the rails supported on the walls of the fuel handling cell. A turntable with two identical telescopic masts is supported on the trolley of the bridge crane. The first mast is equipped with the gripping device for the fuel assemblies and the second mast is equipped with the manipulator arm, which is used for the reparation and maintenance works and for repairing the potential damages in the fuel handling cell. The report describes how postulated upset and accident situations of the fuel handling machine are solved. At the end of the report a rough cost estimate of the fuel handling machine is presented.
