Section: claims

1. A reuse method of eutectic salt waste including nuclides comprising the steps of:a) producing oxychloride, or oxide and e of nuclides through injection and heating of oxygen into the eutectic salt waste including the nuclides;b) performing a layer separation into a precipitate layer of oxide, oxychloride, or oxide and oxychloride and an eutectic salt layer formed on the upper of the precipitate layer by using free settling;c) separating and collecting the precipitate layer and the eutectic salt layer, respectively;d) recollecting the eutectic salt by distilling the separated precipitate layer and condensing the distilled eutectic salt; ande) reusing the eutectic salt collected from step (c) and the eutectic salt recollected in step (d) in an electro refining process of nuclear fuel. 2. The method as set forth in claim 1, wherein oxide, oxychloride, or oxide and oxychloride of the nuclides of the step a) are produced at a temperature of 600 to 700° C. 3. The method as set forth in claim 1, wherein the separation and collection of the step c) uses siphons. 4. The method as set forth in claim 1, wherein the distillation of the step d) is distilled at a temperature of 800 to 1000° C. under a pressure of 0.1 to 100 torr.
