Development and application of photosensitive device systems to studies of biological and organic materials. Third year progress report, January 1, 1992--December 31, 1992

This report describes progress as of the third year of a 3-year DoE grant for 1/1/92 to 12/31/92. Because this is the last year of a 3- year grant cycle, this report will summarize progress over the entire 3-year period. The overall goals of the grant are to develop novel instrumentation and techniques for the performance of biological and materials research, and especially for the development of x-ray detectors suitable for use at storage ring sources. Research progress has been excellent and the overall goals, as well as most of the specific goals have been successfully met.

Evaluation of the DWPF chemical process cell sample condenser in the integrated DWPF melter system (open access)

Evaluation of the DWPF chemical process cell sample condenser in the integrated DWPF melter system

An on-line Analysis system for hydrogen is being added to the Chemical Processing Cell (CPC) in DWPF to ensure that the process does not operate above the lower flammable limit (LFL). The method chosen to measure hydrogen during cold runs is gas chromatography (GC). In order for the GCs to analyze the offgas exiting the SRAT and SME condensers, an additional condenser is required to reduce the dew point of tho sample to below the lowest ambient temperature expected so that no liquid water will enter the GCs. This temperature was chosen to be 10[degrees]C.

Final wash precipitate feed simulants for DWPF Cold Chemical Runs (open access)

Final wash precipitate feed simulants for DWPF Cold Chemical Runs

The Defense Waste Processing Facility (DWPF) is scheduled to start non-radioactive process operation in September, 1992. The Cold Chemical Runs will demonstrate acceptable process operation and provide data required to satisfy the Waste Compliance Plan. Five basic sludge simulants will be required for these tests. Two basic precipitate simulants will be needed to operate the Salt Processing Cell with and without mercury in the precipitate feed. Precipitate feed simulant specifications for DWPF Cold Chemical Runs are revised in this report. All previous specifications of precipitate feed simulants for DWPF Cold Chemical Runs (CCRs) are superceded by this document. The revision is needed to (1) eliminate use of hydroxylamine nitrate (HAN) in the precipitate process operation, (2) simulate the projected composition of the precipitate feed to DWPF produced by final washing to reduce the nitrite concentration to [le] 0.01M without washing the simulated feed, (3) delete organic trim chemical additions to the precipitate feed and (4) specify an additive to prevent foaming of the precipitate. Two specifications are provided to operate the Salt Processing Cell with mercury (Tests 5 6) and without mercury (Tests 1--4) in the precipitate feed.

Formation and retention of methane in coal (open access)

Formation and retention of methane in coal

The formation and retention of methane in coalbeds was studied for ten Utah coal samples, one Colorado coal sample and eight coal samples from the Argonne Premium Coal Sample Bank.Methane gas content of the Utah and Colorado coals varied from zero to 9 cm{sup 3}/g. The Utah coals were all high volatile bituminous coals. The Colorado coal was a gassy medium volatile bituminous coal. The Argonne coals cover a range or rank from lignite to low volatile bituminous coal and were used to determine the effect of rank in laboratory studies. The methane content of six selected Utah coal seams and the Colorado coal seam was measured in situ using a special sample collection device and a bubble desorbometer. Coal samples were collected at each measurement site for laboratory analysis. The cleat and joint system was evaluated for the coal and surrounding rocks and geological conditions were noted. Permeability measurements were performed on selected samples and all samples were analyzed for proximate and ultimate analysis, petrographic analysis, {sup 13}C NMR dipolar-dephasing spectroscopy, and density analysis. The observed methane adsorption behavior was correlated with the chemical structure and physical properties of the coals.

Groundwater flow model for the General Separations Area, Savannah River Site (open access)

Groundwater flow model for the General Separations Area, Savannah River Site

The Savannah River Site (SRS) is a Department of Energy (DOE) facility located near Aiken, South Carolina. Assessment of groundwater flow rates and directions, potential contaminant transport times, and concentration of potential contaminants is required to determine current and future environmental effects resulting from releases by these facilities. Proposed closure actions and/or remedial alternatives also need to be evaluated. Numerical groundwater flow and solute transport models are a means of assessing the environmental effects on the groundwater system. They provide a logical method of integrating all available data into a consistent framework for quantitative analysis. The results of groundwater models can be used directly for input to management decisions and design/construct issues or can provide input into risk assessment models for site evaluations. GeoTrans, Inc. was contracted by the Environmental Restoration Department of WSRC to develop a groundwater model of the entire General Separations Area (GSA). Of particular interest is the area surrounding the Mixed Waste Management Facility (MWMF) as shown in Figure 1.2. The model developed in this phase of the study will be used to assess groundwater flow issues for the entire GSA. The second phase of the study will address contaminant transport issues specific to the area …

Innovative Clean Coal Technologies (ICCT): Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process

The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

Microindentation hardness evaluation of iridium alloy clad vent set cups (open access)

Microindentation hardness evaluation of iridium alloy clad vent set cups

An iridium alloy, DOP-26, is used as cladding for {sup 238}PuO{sup 2} fuel in radioisotope heat sources for space power systems. Presently, DOP-26 iridium alloy clad vent sets (CVS) are being manufactured at the Oak Ridge Y-12 Plant for potential use in the National Aeronautics and Space Administration`s Cassini mission to Saturn. Wrought/ground/stress relieved blanks are warm formed into CVS cups. These cups are then annealed to recrystallize the material for subsequent fabrication/assembly operations as well as for final use. One of the cup manufacturing certification requirements is to test for Vickers microindentation hardness. New microindentation hardness specification limits, 210 to 310 HV, have been established for a test load of 1000 grams-force (gf). The original specification limits, 250 to 350 HV, were for 200 gf testing. The primary reason for switching to a higher test load was to reduce variability in the test data. The DOP-26 alloy exhibits microindentation hardness load dependence, therefore, new limits were needed for 1000 gf testing. The new limits were established by testing material from 15 CVS cups using 200 gf and 1000 gf loads and then statistically analyzing the data. Additional work using a Knoop indenter and a 10 gf load indicated that …
