Method of melting treatment of radioactive miscellaneous solid wastes

摘要

A method of melting treatment of radioactive miscellaneous solid wastes wherein, even when the wastes contain various kinds of substances in a mixed state, each of the substances is efficiently induction-heated and the whole of the wastes can be melted quickly. The radioactive miscellaneous solid wastes are charged into a water-cooling type cold crucible induction melting furnace disposed within a high-frequency coil. A plurality of high-frequency currents each having a frequency suitable for induction-heating each of the various kinds of substances contained in the radioactive miscellaneous solid wastes are supplied to the high-frequency coil to melt the solid wastes by being induction-heated. The high-frequency currents of different frequencies may be simultaneously supplied to a single high-frequency coil or may be supplied to a plurality of high-frequency coils, respectively.
