To provide a uranium oxide to metal transformation and filtration recovery device which reacts uranium oxide powder with lithium metal in chloride lithium molten salt medium, transforms those to uranium metal powder, separates the transformed uranium metal powder from the chloride lithium molten liquid by a direct filtration method, and recovers the powder.
The uranium oxide to metal transformation and filtration recovery device comprises: a heating furnace 10; a reaction vessel 25 with a cone shape bottom; a sealing lid 35; argon gas injection pipe and exhaust pipe; valve assemblies (37,39) for opening/closing the outlet; one or more stirrers 30; a lithium metal supplier 60; a reactor 20 including a cooling jacket; a porous filter 40 for filtering mixed material exhausted out of the reactor; and a molten salt recovery tank 50. The device transforms uranium oxide to uranium metal by the reaction with lithium in a high temperature molten salt system, and separates and recover the transformed metal from the molten salt by way of the porous filter 40.
