Disclosed are a czochralski apparatus for growing crystals and a purification method of waste salts using the same. More particularly, the present invention provides a czochralski apparatus for growing crystals comprising screw thread for fixing salt crystals mounted on a pulling bar of the apparatus in order to prevent desorption of crystals caused by load thereof during a crystal growing process without requiring alternative seed crystals and, in addition, a method for purification of waste salts, which can isolate impurities from molten waste salts using a czochralski crystal growing process without alternative adsorption medium, does not generate secondary wastes and may continuously purify the waste salts.

Disclosed are a method and an apparatus for continuously casting a uranium rod so that impurities generated in melting the metallic substance reduced from nuclear spent fuel are easily removed, the molten metal is easily degassed, the oxidation of uranium is prevented, and the molten metal does not remain in a crucible, thereby completely removing the noxious gas, improving the safety of work, allowing the workers to be close to the apparatus, reducing the consumption rate of the inert gas, completely preventing the oxidation of uranium, and being remotely controlled.
