Abstract

A method for disposing of nuclear-reactor wastes by in-situ incorporation in molten silicate rock involves injecting liquid wastes into a deep underground chimney and allowing them to self-boil. The resulting steam is processed at the ground surface and recycled into a closed system. When waste addition is terminated, the chimney is allowed to boil dry, thereby solidifying the waste. The heat generated by the radioactive waste then melts the surrounding rock, which dissolves the waste. Finally, the rock resolidifies, trapping the radioactivity in an insoluble rock matrix deep underground. This method has significant environmental and economic advantages over previously proposed methods.
