Zusammenfassung:PURPOSE: To provide a device for reactor fuel treatment capable of reducing the period of fuel treatment by utilizing a plurality of dollys for fuel treatment and a dolly loading a traversing dolly fixed with multiple step extension mast on a track laid on the upper surface of a reactor pit and the frame of a fuel rack. CONSTITUTION: A track 14 is laid on the upper surface of a reactor pit 1 floor and the frame of a fuel rack 2, and a fuel treating dolly 64 is made possible to run on the track 14. On a dolly 73 running on the track on an operation floor 103 above a reactor pressure vessel 100, a traversing dolly 79 fixed with a multiple step extension mast 71 for elevating fuel 54 is loaded.
