Characterization of solids in the Three Mile Island Unit 2 Reactor defueling water: Addendum

Description: Shortly after ORNL/TM-10362 was issued, it was discovered that a series of 31 figures had been inadvertently omitted. These figures, which consist of scanning electron microscope (SEM) photographs and energy-dispersive X-ray fluorescence scans, provide significant information about the results obtained in the tests performed with water sample W3. This Addendum includes these figures. Details of and comments on the SEM photographs may be found in ORNL/TM-10362.

Waste acid detoxification and reclamation: Phase 1, Project planning and concept development

Description: The objectives of this project are to develop processes for reducing the volume, quantity, and toxicity of metal-bearing waste acids. The primary incentives for implemeting these types of waste minimization processes are regulatory and economic in that they meet requirements in the Resource Conservation and Recovery Act and reduce the cost for treatment, storage, and disposal. Two precipitation processes and a distillation process are being developed to minimize waste from fuel fabrication oper… more

Costs of nuclear waste glassmaking at Savannah River

Description: Recently developed reference schedules for processing high-level nuclear wastes into solid glass froms at Savannah River provide bases for economic evaluations of potential improvements of glass melter design and operation. Greater melter output is achieved through increases in capacity and attainment and possible higher glass waste loadings. The economic evaluation indicates only minor beneficial impacts on total waste disposal costs for melter outputs greater than current reference values. In… more

Transportation of tritiated waste from fusion facilities

Description: This paper examines methods of handling tritiated waste from a fusion facility, concentrating on handling requirements specific to tritium. Gaseous effluent from a fusion reactor can currently be transported from a fusion facility in two forms )endash) as a gas or solidified on uranium beds. Tritiated water can be transported if it is solidified by absorption onto molecular sieve beds or on clay or cement. Solid waste being shipped for disposal can be transported in low specific activity (LSA, … more

Treatment of ORNL liquid low-level waste

Description: Discontinuation of the hydrofracture disposal method at Oak Ridge National Laboratory (ORNL) has caused intensive efforts to reduce liquid waste generation. Improving the treatment of slightly radioactive liquid waste, called process waste, has reduced the volume of the resulting contaminated liquid radioactive waste effluent by 66%. Proposed processing improvements could eliminate the contaminated liquid effluent and reduce solid low-level waste by an additional one-third. The improved process… more

Control of radioactive waste-glass melters: Part 3, Glass electrical stability

Description: Pilot waste-glass melter operations have indicated a tendency for noble-metal fission-product accumulation on melter floors, which can lead to distortion of electric heating patterns, and decrease melter life. Changes in melter geometry are being considered in Japan, Germany, and the United States to permit draining of the noble metals to reduce their effects. Physical modeling of melter electrical patterns, electrode/waste-glass electrochemistry, and non-linear electrical behavior have been ev… more

Demonstration of a steam jet scrubber off-gas system and the burner efficiency of a mixed waste incinerator facility

Description: A full-scale incinerator system, the Consolidated Incineration Facility (CIF), is being designed to process solid and liquid low-level radioactive, mixed, and RCRA hazardous waste. This facility will consist of a rotary kiln, secondary combustion chamber (SCC), and a wet off-gas system. A prototype steam jet scrubber off-gas system has been tested to verify design assumptions for the CIF. The scrubber wastewater will be immobilized in a cement matrix after the blowdown has been concentrated to … more

An experimental survey of the factors that affect leaching from low-level radioactive waste forms

Description: This report represents the results of an experimental survey of the factors that affect leaching from several types of solidified low-level radioactive waste forms. The goal of these investigations was to determine those factors that accelerate leaching without changing its mechanism(s). Typically, although not in every case,the accelerating factors include: increased temperature, increased waste loading (i.e., increased waste to binder ratio), and decreased size (i.e., decreased waste form vol… more

Lessons learned at West Valley during facility decontamination for re-use (1982--1988)

Description: The primary mission of the West Valley Demonstration Project (WVDP) is to solidify a large volume of high-level liquid waste (2.3 million liters -- 600,000 gallons) produced during reprocessing plant operations and stored in underground tanks. This is to be accomplished through the maximum use of existing facilities. This required a significant effort to remove existing equipment and to decontaminate areas for installation of liquid and cement processing systems in a safe environment while main… more

Performance testing of blast furnace slag for immobilization of technetium in grout

Description: This paper presents preliminary results of a grout development effort to identify grout formulas that can satisfactorily sequester /sup 99/Tc contained in an existing Portsmouth Gaseous Diffusion Plant waste. Technetium is of particular concern to the US Nuclear Regulatory Commission (NRC) because of its mobility and biological activity. The mobility of technetium results in large part from the movement of the pertechnate anion (prevalent in low-level radioactive waste (LLW)) through soil and g… more

Estimation of Ground-Water Travel Time at the Hanford Site: Description, Past Work, and Future Needs

Description: The time for a contaminant to travel from a source to the biosphere is only one component of evaluating the consequences of ground-water contamination in the unconfined aquifer at the Hanford Site. The three components necessary for evaluating consequences of contamination are the location of contaminant outflow to the biosphere, the time of contaminant arrival at the outflow location, and the quantity of contaminants reaching the outflow location. This report focuses on one component, the cont… more
