An integrated systems engineering approach is used for uniform comparison of widely varying thermal treatment technologies proposed for management of contact-handled mixed low-level waste (MLLW) currently stored in the U.S. Department oi"Energy complex. Ten different systems encompassing several incineration design options are studied. All subsystems, including facilities, equipment, and methods needed for integration of each of the ten systems are identified. Typical subsystems needed for complete treatment of MLLW are incoming waste receiving and preparation (characterization, sorting, sizing, and separation), thermal treatment, air pollution control, primary and secondary stabilization, metal decontamination, metal melting, mercury recovery, lead recovery, and special waste and aqueous waste treatment. The evaluation is performed by developing a preconceptual design package and planning life-cycle cost (PLCC) estimates for each system. As part of the preconceptual design process, functional and operational requirements, flow sheets and mass balances, and conceptual equipment layouts are developed for each system. The PLCC components estimated are technology development, production facility construction, pre-operation, operation and maintenance, and decontamination and decommissioning. Preconceptual design data and other technology information gathered during the study are examined and areas requiring further development, testing, and evaluation are identified and recommended. Using a qualitative method, each of the ten systems are ranked.

“…The solution process starts with an initial guess, which is subsequently refined by solving equation (25) The on going efforts at IRC to develop and construct a bench-scale arc melter for mixed wastes treatments have resulted in a good database on the final waste form composition and are well documented in the report by Grandy et al (1993). Table 5 summarizes the species generated for a number of different waste stream containing hydrated metal oxide sludges.…”

“…Information from Arrenholz and Knight (1991) and Grandy, Eddy, and Anderson (1993) were used to determine waste volumes and types for the simulated field-scale test. Waste volume in SDA pits varies from about 21-50 vol % of the total excavated volume.…”

This Work Plan provides technical details for conducting a treatability study that will evaluate the application of in situ thermal desorption (ISTD) to landfill waste at the Subsurface Disposal Area (SDA) at the Idaho National Engineering and Environmental Laboratory (INEEL). ISTD is a form of thermally enhanced vapor vacuum extraction that heats contaminated soil and waste underground to raise its temperature and thereby vaporize and destroy most organics. An aboveground vapor vacuum collection and treatment system then destroys or absorbs the remaining organics and vents carbon dioxide and water to the atmosphere. The technology is a byproduct of an advanced oil-well thermal extraction program. The purpose of the ISTD treatability study is to fill performance-based data gaps relative to off-gas system performance, administrative feasibility, effects of the treatment on radioactive contaminants, worker safety during mobilization and demobilization, and effects of landfill type waste on the process (time to remediate, subsidence potential, underground fires, etc.). By performing this treatability study, uncertainties associated with ISTD as a selected remedy will be reduced, providing a better foundation of remedial recommendations and ultimate selection of remedial actions for the SDA. SUMMARYThis Work Plan provides technical details for conducting a treatability study to determine the effectiveness, implementability, and cost of applying in situ thermal desorption (ISTD) to subsurface waste at the Subsurface Disposal Area (SDA) at the Idaho National Engineering and Environmental Laboratory (INEEL). The SDA falls under the jurisdiction of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, 42 USC § 9601 et seq.). ISTD is one of several treatment options identified in the addendum to the Work Plan for the Operable Unit (OU) 7-13/14 Waste Area Group 7 Comprehensive Remedial Investigation/Feasibility Study (RI/FS). The purpose of this treatability study is to fill performance-based data gaps relative to ISTD. By performing the ISTD treatability study, uncertainties associated with selecting remedies will be reduced. Therefore, a better foundation will be provided for remedial recommendations and the ultimate selection of remedial actions for the SDA.The overall objective of the ISTD treatability study is to provide sufficient data to evaluate ISTD either as a pretreatment to some other technology or as a long-term in situ disposal option at the SDA. The ISTD Treatability Study Work Plan provides the technical details for conducting the tests, managed through a graded risk approach. The current study will take place in three phases: lab-scale (radioactive), field-scale (nonradioactive), and field-scale (radioactive). The nonradioactive field-scale test will use comparable matrices with surrogates in place of hazardous and radiological contaminants. If the results of this phase are sufficiently encouraging, the technology will then be tested at a radioactive site containing a...
