Disclosed herein is a method of preparing uranium metal by electrorefining uranium metal, comprising: applying a predetermined current to an anode electrode included in an anode basket receiving fuel segments made of uranium metal and a cathode electrode of carbon material; electrodepositing uranium on the cathode electrode in accordance with the reaction initiated by the applied current; and collecting the electrodeposited uranium by self-weight. An apparatus for electrorefining uranium metal used in the method according to the present invention, comprises: an anode basket ( 6 ) receiving fuel segments made of uranium metal and comprising an anode electrode; and a reactor including a cathode electrode ( 5 ) made of carbon material and a uranium collector ( 10 ) therein. According to the method of the present invention having the above mentioned constitution and the apparatus thereof, it is possible to separate only pure uranium metal with a high capability from the spent metal nuclear fuels conveniently and economically.
