Radioactive waste not classified as high-level waste, TRU waste, or spent nuclear fuel, or the tailings or waste produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content. Test specimens of fissionable material irradiated for research and development only, and not for the production of power or plutonium, may be classified as LLW, provided the concentration of TRU elements is less than 100 mCi per gram.
