Management of radioactive mixed wastes in commercial low-level wastes. Draft report for comment

Technical Report ·
OSTI ID:6263776
; ;
Management options for three generic categories of radioactive mixed waste in commercial low-level wastes (LLW) have been identified and evaluated. These wastes were characterized as part of a BNL study in which LLW generators were surveyed for information on potential chemical hazards in their wastes. The general management targets adopted for mixed wastes are destruction, immobilization, and reclamation. Solidification, adsorption, incineration, acid digestion, wet-air oxidation, distillation, liquid-liquid solvent extraction, specific chemical destruction technique, and substitution have been considered for organic liquid wastes. Containment, segregation, decontamination, and solidification or containment of residues, have been considered for lead metal wastes which have themselves been contaminated and are not used for purposes of waste disposal shielding, packaging, or containment. For chromium-containing wastes, solidification, incineration, wet-air oxidation, acid digestion, containment, and substitution have been considered. For each of these wastes, the management option evaluation has included an assessment of testing appropriate to determine the effect of the option on both the radiological and potential chemical hazards present.
