    摘要: Disclosed is a water-soluble coating composition, which is applied on the surface of fuel rods to prevent scratching of the surface of the fuel rods upon manufacturing a nuclear fuel assembly for light water reactors. This water-soluble coating composition facilitates the formation and removal of a coating film and the resulting coating film can exhibit strength and durability equivalent to those of an existing lacquer (nitrocellulose) coating film, and can thus be used as an alternative to lacquer, thereby easily removing the coating film and improving workplace safety, ultimately achieving improvements in the working environment and high workplace safety.

In detail, the melting furnace includes a crucible into which the metal waste is input, and an induction coil which is wound around the crucible to melt the metal waste. The induction coil has a hollow hole in which cooling fluid flows. The high frequency generator applies high-frequency current to the induction coil. The ladle supplies molten metal, from which slag has been removed in the crucible, into molds. The bogie is disposed adjacent to the ladle and is provided with the molds, each of which forms an ingot using the molten metal supplied thereinto. The cooling unit cools the cooling fluid and circulates it along the induction coil. The dust collector filters out dust and purifies gas.
