Identifying Fracture Types and Relative Ages Using Fluid Inclusion Stratigraphy

Enhanced Geothermal Systems (EGS) are designed to recover heat from the subsurface by mechanically creating fractures in subsurface rocks. Understanding the life cycle of a fracture in a geothermal system is fundamental to the development of techniques for creating fractures. Recognizing the stage of a fracture, whether it is currently open and transmitting fluids; if it recently has closed; or if it is an ancient fracture would assist in targeting areas for further fracture stimulation.

SIEMENS ADVANCED QUANTRA FTICR MASS SPECTROMETER FOR ULTRA HIGH RESOLUTION AT LOW MASS

The Siemens Advanced Quantra Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer was evaluated as an alternative instrument to large double focusing mass spectrometers for gas analysis. High resolution mass spectrometers capable of resolving the common mass isomers of the hydrogen isotopes are used to provide data for accurate loading of reservoirs and to monitor separation of tritium, deuterium, and helium. Conventional double focusing magnetic sector instruments have a resolut… more

Characterization of mixed CH-TRU waste for the WIPP Experimental Test Program conducted at ANL-W

Argonne National Laboratory is participating in the Department of Energy`s Waste Isolation Pilot Plant (WIPP) Experimental Test Program by characterizing and repackaging mixed contact-handled transuranic waste. Characterization activities include gas sampling the waste containers, visually examining the waste contents, categorizing the contents according to their gas generation potentials, and weighing the contents. The waste is repackaged from 0.21m{sup 3} (55 gallon) drums into instrumented s… more

The transportable heavy-duty engine emissions testing laboratory. Annual progress report, April 1990--April 1991

West Virginia University has designed and constructed a Transportable Emissions Testing Laboratory for measuring emissions from heavy duty vehicles, such as buses and trucks operating on conventional and alternative fuels. The laboratory facility can be transported to a test site located at, or nearby, the home base of the vehicles to be tested. The laboratory has the capability of measuring vehicle emissions as the vehicle is operated under either transient or steady state loads and speeds. Th… more

Geophysical investigation of burn pit, 128-H-1, 100-H Area

The 128-H-1 burn pit is located in the northeast corner of 100-H Area. The objective of the survey was to delineate subsurface features in the 128-H-1 burn pit that may affect the emplacement of soil-gas probes. Ground-penetrating radar (GPR) and electromagnetic induction (EMI) were the two techniques used in the investigation. The methods were selected because they are non-intrusive, relatively fast, economical, and have been used successfully in other geophysical investigations on the Hanford… more

Lithium-aluminum separations request

A test irradiation of lithium was recently completed in one of the Hanford K Reactors. It is requested that these lithium-aluminum alloy targets be separated and analyzed for tritium content. This request is for the analysis to be performed on two groups or batches of samples. The first group would be 38 elements with a total gas content estimated to be approximately 97 liters. The second batch would consist of 76 elements with a total gas content estimated to be approximately 193 liters. This … more

Flammable gas generation, retention, and release in high-level waste tanks -- physical and chemical models

The most evident dangers from flammable gas release in ventilated high-level waste tanks at Hanford are those caused by periodic release of gases generated and retained in depths of the tanks. In Hanford Tank 101-SY the flammable gases and hydrogen, ammonia and methane are accumulated along with oxidizer nitrous oxide in bubbles while the ammonia and nitrous oxide are also deposited in solution. Accumulation of both the free and dissolved gases is enhanced by hydrostatic pressure. The free gase… more

Miniaturized Environmental Monitoring Instrumentation

The objective of the Mass Spectrograph on a Chip (MSOC) program is the development of a miniature, multi-species gas sensor fabricated using silicon micromachining technology which will be orders of magnitude smaller and lower power consumption than a conventional mass spectrometer. The sensing and discrimination of this gas sensor are based on an ionic mass spectrograph, using magnetic and/or electrostatic fields. The fields cause a spatial separation of the ions according to their respective … more

Graphite burn-out resulting from carbon monoxide formation in C Pile

With the introduction of carbon dioxide into the piles as a gas atmosphere, new problems arose which concerned the chemical reactions undergone by the pile graphite with the gas atmosphere. In the interest of obtaining a better understanding of the nature and extent of these graphite-gas reactions, mass spectrometer analyses of the pile gas from a selected sampling port at C Pile were initiated at the time of start-up of that unit and were continued until several steady state conditions had bee… more

Testing of the Pleasant Bayou Well through October 1990

Pleasant Bayou location was inactive from 1983 until the cleanout of the production and disposal wells in 1986. The surface facilities were rehabilitated and after shakedown of the system, additional repair of wellhead valves, and injection of an inhibitor pill, continuous long-term production was started in 1988. Over two years of production subsequent to that are reviewed here, including: production data, brine sampling and analysis, hydrocarbon sampling and analysis, solids sampling and anal… more

Development of inexpensive continuous emission monitors for feedback control of combustion devices that minimize greenhouse gases, toxic emissions, and ozone damaging products

This is the final report of a three-year, Laboratory Directed Research and Development project at the Los Alamos National Laboratory. Combustion is the major cause of poor urban air quality, of depletion of the ozone layer, and a major source of the greenhouse gas, carbon dioxide. Careful control of combustor conditions is important for minimizing the effects of combustion on the environment. The authors have developed sensitive, inexpensive continuous emission monitors that will assist in dire… more

Interpretation of chemical and isotopic data from boreholes in the unsaturated zone at Yucca Mountain, Nevada

Analyses of pore water from boreholes at Yucca Mountain indicate that unsaturated-zone pore water has significantly larger concentrations of chloride and dissolved solids than the saturated-zone water or perched-water bodies. Chemical compositions are of the calcium sulfate or calcium chloride types in the Paintbrush Group (Tiva Canyon, Yucca Mountain, Pah Canyon, and bedded tuffs), and sodium carbonate or bicarbonate type water in the Calico Hills Formation. Tritium profiles from boreholes at … more

Progress in resolving Hanford Site high-level waste tank safety issues

Interim storage of alkaline, high-level radioactive waste, from two generations of spent fuel reprocessing and waste management activities, has resulted in the accumulation of 238 million liters of waste in Hanford Site single and double-shell tanks. Before the 1990`s, the stored waste was believed to be: (1) chemically unreactive under its existing storage conditions and plausible accident scenarios; and (2) chemically stable. This paradigm was proven incorrect when detailed evaluation of tank… more
