Apparatus for simultaneously measuring electrical conductivity and oxygen fugacity (open access)

Apparatus for simultaneously measuring electrical conductivity and oxygen fugacity

Electrical conductivity studies of silicates are useful in determining temperature vs depth in the earth. Realistic laboratory measurements of conduction mechanisms require that exact determinations of oxygen fugacity (fo{sub 2}) be made in the experimental environment. An apparatus is described that monitors system fo{sub 2} with a calcia-doped zirconia-oxygen cell while measuring electrical conductivity of iron-bearing silicates at high temperature (greater than 1000 K). The fo{sub 2} calculated thermodynamically from CO/CO{sub 2} mixing ratios agreed well with measurements made with the zirconia cell at 1473 K, except for fo{sub 2} greater than 10{sup -4} Pa, where, on a log{sub 10} scale, mixing-ratio errors were as large as +- 0.2. These errors are attributed to oxygen contamination in the CO{sub 2} and to mobile carbon deposits that formed in the apparatus.

Helium generation in fusion reactor materials. Technical progress report, April--September 1977 (open access)

Helium generation in fusion reactor materials. Technical progress report, April--September 1977

The near-term objectives of this program are to measure the spectrum-integrated helium generation rates and cross sections of a number of pure elements and alloys in several high-intensity neutron sources, and to develop and demonstrate neutron dosimetry procedures using some of these materials. To this end, four neutron irradiation experiments have now been run: one using accelerator-produced d-Be neutrons, two using the accelerator-produced d-T reaction, and one in the neutron field of a mixed-spectrum fission reactor. All of these irradiations have incorporated a large number of helium-generation materials.

Homogenization of arc-melted uranium-6 weight percent niobium alloy ingots (open access)

Homogenization of arc-melted uranium-6 weight percent niobium alloy ingots

Microsegregation and macrosegregation in uranium-6 niobium arc-melted ingots were characterized by electron microprobe analysis. Homogenization studies determined that microsegregation can be eliminated by heat treating the alloy for six hours at 1100/sup 0/C. Extensive homogenization did not eliminate macrosegregation (banding) from the as-cast alloy, but a mathematical model describing banding and coring indicated that banding could possibly be eliminated by working prior to homogenization.

Impedance camera: a system for determining the spatial variation of electrical conductivity

A data collection and data interpretation method is presented for predicting, from measurements made on the periphery of the core sample, the electrical conductivity distribution within core samples. This method uses an array of electrodes on the periphery to probe through the core sample. Surprisingly accurate detail can be seen in the estimated conductivity distribution. This method has been demonstrated using synthetic examples modeled and analyzed on a computer. Extensions of the procedure may be useful in subsurface geophysical probing and remote probing methods using physical phenomena satisfying Laplace's equation.

Compact heat exchangers for sea thermal power plants. Final technical progress report, May 1, 1977--March 31, 1978

The investigative studies required to develop a low cost, high performance flat plate heat exchanger design suitable for sea thermal power plants are covered. The studies indicate that higher boiling transfer coefficients quoted in the literature can be attained in a flat plate exchanger. The study has examined the effect of various fouling rates. A cleaning concept is proposed that is simple, high speed and easy to operate without plant or exchanger shutdown during the cleaning process. The exchanger concept for both boilers and condensers is a low profile, mechanical assembled structure with no welding, soldering, or brazing required. The exchanger design has been evaluated for manufacturability and ease of shipping, installation, and maintenance in a power plant. A preliminary arrangement for exchangers of this construction in a full scale power plant has been examined to provide confidence that the design would be usable in such a plant. Computer programs have been written to optimize design conditions for boilers and condensers in a power plant, recognizing costs of exchangers, cost of warm and cold water, water pumping power and effect of cycle efficiency. After optimizing design conditions a conceptual design has been prepared for a test boiler and a test …

Data accumulation on the methane potential of the coal beds of Colorado. Final report

A two-year project was conducted to gather data that would assist in the evaluation of the methane potential of the coal beds of Colorado. It was found that a number of closed underground coal mines in the State had reported gassy conditions or had experienced fires and explosions of varied intensity and frequency. The majority of such occurrences have been in those areas characterized by coals of relatively low (i.e., below 31%) volatile matter (VM) content. The south half of the Raton Mesa coal region (Las Animas County) and the southeastern part of the Unita region (in Gunnison and Pitkin Counties) contain coals with the lowest percentages of VM, the gassiest producing mines, and the highest grade coking coal in the State. Five active mines in Pitkin County presently are emitting a total of over 8 million cu ft of methane per day. These mines produce the highest quality metallurgical-grade coal in the western US (high-volatile A and medium-volatile bituminous). The gassy coals in these two regions range from Late Cretaceous to Paleocene in age and usually occur in areas related to igneous activity of late Tertiary age. The VM percentages of Colorado coals can be used, with some caution, …

Delayed fracture of silicon. Silicon sheet growth development for the Large Area Silicon Sheet Task of the Low Cost Silicon Solar Array Project. Final report

Bar specimens were cut from ingots of single crystal silicon, and acid-etched prior to testing. Artificial surface flaws were introduced in specimens by indentation with a Knoop hardness tester. The specimens were loaded in four-point bending to 95% of the nominal fracture stress, while keeping the surface area, containing the flaw, wet with test liquids. No evidence of delayed fracture, and, therefore stress corrosion, of single crystal silicon was observed for liquid environments including water, acetone and aqueous solutions of NaCl, NH/sub 4/OH, and HNO/sub 3/, when tested with a flaw parallel to a (110) surface. The fracture toughness was calculated to be K/sub IC/ = 0.591 x 10/sup 6/ N/m/sup 3/2/.

Evaluation of ultrafiltration membranes for treating low-level radioactive contaminated liquid waste (open access)

Evaluation of ultrafiltration membranes for treating low-level radioactive contaminated liquid waste

A series of experiments were performed on Waste Disposal Facility (WD) influent using Romicon hollow fiber ultrafiltration modules with molecular weight cutoffs ranging from 2000 to 80,000. The rejection of conductivity was low in most cases. The rejection of radioactivity ranged from 90 to 98%, depending on the membrane type and on the feed concentration. Typical product activity ranged from 7 to 100 dis/min/ml of alpha radiation. Experiments were also performed on alpha-contaminated laundry wastewater. Results ranged from 98 to >99.8%, depending on the membrane type. This yielded a product concentration of less than 0.1 dis/min/ml of alpha radiation. Tests on PP-Building decontamination water yielded rejections of 85 to 88% alpha radiation depending on the membrane type. These experiments show that the ability to remove radioactivity by membrane is a function of the contents of the waste stream because the radioactivity in the wastewater is in various forms: ionic, polymeric, colloidal, and absorbed onto suspended solids. Although removal of suspended or colloidal material is very high, removal of ionic material is not as effective. Alpha-contaminated laundry wastewater proved to be the easiest to decontaminate, whereas the low-level PP-Building decontamination water proved to be the most difficult to decontaminate. Decontamination of …
