The melting and discharge technique of UO{sub 2}/ZrO{sub 2} mixtures using the cold crucible melting method that does not need a separate crucible such as tungsten one with high melting point is developed and applied to the KAERI FCI test called TROI. To discharge the melt from a cold crucible into a fuel-coolant interaction chamber after melting, a plug is specially designed using the concept for electro-magnetic field characteristics so as to as thin as possible the crust that is formed between the melt and plug. Its function keeps the melt in the crucible during melting period and provides the melt discharge path. About 8.5 kg melt is discharged from the cold crucible to the melt-water interaction chamber through the punched hole with 8 cm in diameter. The melt temperature is also measured and analyzed from observation of the melt surface. The power balance using the operating parameters such as current, voltage and coupling factor of R.F generator is analyzed. (authors)
