Abstract
The present invention provides for methods for on-line monitoring of a molten process phase to determine the extent of extraction of radioactive species from a waste metal contaminated with the radioactive species. The waste metal is mixed with an inorganic flux material in a furnace, wherein the flux material extracts the radioactive species from the waste metal. Periodically, a portion of the furnace composition is sampled from the furnace and separated into a molten flux phase and a molten metal phase. Either of these phases is then analyzed in its molten state to determine the extent of the extraction process.
