Abstract:
Method and apparatus for the incineration and vitrification of radioactive waste materials. Waste materials are fed into a melter containing molten glass wherein the waste is incinerated and vitrified into the glass matrix. Gases produced are combusted in an extended plenum area preferably designed to provide a residence time of at least 3 seconds. A portion of the sulfur compounds in the combustion gases are incorporated into a solid matrix of gypsum by contacting the sulfur compounds with an aqueous solution and calcium hydroxide.
