Low-Level Waste Management - Suggested Solutions for Problem Wastes
Problem wastes are those wastes which are difficult or require unusual expense to place into a waste form acceptable under the requirements of 10 CFR 61 or the disposal site operators. Brookhaven National Laboratory has been investigating the use of various solidification agents as part of the DOE Low-Level Waste Management Program for several years. Two of the leading problem wastes are ion exchange resins and organic liquids. Ion exchange resins can be solidified in Portland cement up to about 25 wt % resin, but waste forms loaded to this degree exhibit significantly reduced compressive strength and may disintegrate when immersed in water. Ion exchange resins can also be incorporated into organic agents. Mound Laboratory has been investigating the use of a joule-heated glass melter as a means of disposing of ion exchange resins and organic liquids in addition to other combustible wastes

Department of Energy LLW disposal; adapting to a changing environment
The Department of Energy's philosophy is evolving to meet the challenge of providing safe and cost-effective LLW management. The DOE expects to use a system approach by obtaining consensus on performance requirements with all of the involved regulatory agencies and by applying these performance requirements to the best available site. Engineered features will be added either through the stabilization of the waste or site improvements as required to meet the performance requirements. Necessary waste stabilization will be incorporated into the waste acceptance criteria relieving the operator from making waste treatment decisions on a strict cost-effectiveness basis. The initial analysis to determine a configuration which meets minimum performance requirements will also serve as the baseline for additional analyses to meet the ALARA requirements
