Summary:
LECO crucibles and incinerator ash are two waste categories that cannot be discarded due to the presence of insoluble transuranics. Current chemical processing methods are not too effective, requiring a number of repeated operations in order to dissolve more than half the transuranics. An alternate dissolution approach has been developed involving the use of ammonium bifluoride. Low temperature fusion of the waste with ammonium bifluoride is followed by dissolution of the fused material in boiling nitric acid solutions. Greater than 60% of the transuranics contained in LECO crucibles and greater than 95% of the transuranics mixed with the incinerator ash are dissolved after a single fusion and dissolution step. Fluorination of the transuranics along with other impurities appears to render the waste material soluble in nitric acid.
