... Salt Stabilization 4. Waste Form Performance Nondestructive examination and nondestructive assay techniques and equipment are required to determine the nature of the waste matrix in any package, confirm the presence and concentration of regulated materials and radionuclides, and identify characteristics of concern for operational safety and process continuity.

... VOC/SVOC Monitor The State of Development of Waste Form Ash stabilization processes are required that increase waste loadings, improve durability, and/or reduce the volume increase typical of today's standard practices. Though mercury monitors are commercially available, it would be advantageous to develop real-time continuous emission monitors requiring minimal consumables and Tow maintenance, with operating ranges covering the emission limits typical of thermal treatment processes.

... Filters capable of operating at high temperatures, typical at the outlet of thermal treatment processes, and capable of removing a substantial fraction of the particulates prior to quenching or scrubbing are required. More complete information on the partitioning of radionucTides between the final waste form, the off-gas, and any secondary wastes in mixed waste treatment processes is needed to support equipment design and process permitting.

... Approaches are required to enhance the performance of candidate sludge washing technologies to demonstrate feed preparation and washing of process residues, sludges and particulates to RCRA requirements. Operating techniques and equipment design are required to facilitate decanting or transfer of molten materials from furnaces in an effective, reliable and safe manner in a radioactive environment.
