Active layer hydrology for Imnavait Creek, Toolik, Alaska. Annual progress report, July 1984--January 1986

Description: In the annual hydrologic cycle, snowmelt is the most significant event at Imnavait Creek located near Toolik Lake, Alaska. Precipitation that has accumulated for more than 6 months on the surface melts in a relatively short period of 7 to 10 days once sustained melting occurs. During the ablation period, runoff dominates the hydrologic cycle. Some meltwater goes to rewetting the organic soils in the active layer. The remainder is lost primarily because of evaporation, since transpiration is not… more

Analysis of earthquake data recorded by digital field seismic systems, Jackass Flats, Nevada

Description: Analysis of 59 time series from ten small magnitude earthquakes recorded in 1981 by portable digital seismic systems at the southern Nevada Test Site (NTS) yielded several significant results. We find that moment magnitude (M/sub L/) (local magnitude determined from seismic moment) correlates closely with coda duration magnitudes M/sub d/ determined by the Southern Great Basin Seismic Network (SGBSN). Further, local magnitude M/sub W A/ computed from displacement seismograms simulating Wood-And… more

Assessment of electrochemical potentiokinetic reactivation tests to qualify stainless steel for nitric acid service

Description: To minimize the costs and delivery time delays associated with purchasing type 304L stainless steel materials for service in nitric-acid-containing media, an alternative to the current Oak Ridge Y-12 Plant requirement of testing in accordance with American Society for Testing and Materials (ASTM) A 262, Practice C (the boiling nitric acid test), is being sought. A possible candidate is the electrochemical potentiokinetic reactivation (EPR) test being developed for the nuclear industry and under… more

Binary condensation in a supersonic nozzle

Description: Experiments in nozzles are extremely important because they provide higher rates of cooling, higher supersaturations and higher nucleation rates than any of the other techniques. Their operating conditions are more typical of the important industrial conditions such as aerodynamic and turbomechanical flows where homogeneous nucleation can have serious consequences. Because the fluid mechanics of nozzles are well defined and understood, nucleation experiments in the nozzle are amenable to sophis… more

Borehole gravity meter survey in drill hole USW G-4, Yucca Mountain Area, Nye County, Nevada

Description: Drill hole USW G-4 was logged with the US Geological Survey borehole gravity meter (BHGM) BH-6 as part of a detailed study of the lithostratigraphic units penetrated by this hole. Because the BHGM measures a larger volume of rock than the conventional gamma-gamma density tool, it provides an independent and more accurate measurement of the in situ average bulk density of thick lithologic units. USW G-4 is an especially important hole because of its proximity to the proposed exploratory shaft at… more

Characterization of uranium surfaces machined with aqueous propylene glycol-borax or perchloroethylene-mineral oil coolants

Description: The use of perchloroethylene (perc) as an ingredient in coolants for machining enriched uranium at the Oak Ridge Y-12 Plant has been discontinued because of environmental concerns. A new coolant was substituted in December 1985, which consists of an aqueous solution of propylene glycol with borax (sodium tetraborate) added as a nuclear poison and with a nitrite added as a corrosion inhibitor. Uranium surfaces machined using the two coolants were compared with respects to residual contamination,… more

[Circulation and exchange processes on the South Atlantic Bight Continental Shelf]. [Progress summary for 1986]

Description: A continuation of the physical oceanography program to investigate circulation and exchange processes on the South Atlantic Bight (SAB) Continental Shelf is proposed. The transport and dispersal of materials entering the inner shelf zone with river discharge is not well understood at present. Climatological data, satellite imagery, and numerical modeling results indicate two removal routes for these nearshore waters: northeast transport and offshore exchange between Cape Fear and Savannah durin… more

Consistent set of thermodynamic constants for americium (III) species with hydroxyl and carbonate

Description: A consistent set of thermodynamic constants for aqueous species and compounds of Am(III) with hydroxyl and carbonate ligands has been developed. The procedure used to develop these constants involved establishing a value for one formation constant at a time in a sequential order, starting with the hydrolysis products and hydroxide solids, and then proceeding to carbonate species. The EQ3NR chemical-equilibrium model was used to test the constants developed. These constants are consistent with m… more

Evaluation of the geological relationships to gas hydrate formation and stability. Second annual technical progress report, October 1, 1985--September 30, 1986

Description: Although there are many publications pertaining to gas hydrates, their formation and stability in various geological conditions are poorly known. Therefore, for the same reasons and because of the very broad scope of our research, limited amount and extremely dispersed information, the study regions are very large. Moreover, almost without exception the geological environments controlling gas hydrates formation and stability of the studied regions are very complex. The regions studied (complete… more

Description: Status of the shock tube data system is reported. A corrected analysis of data on reactions of NF{sub 2} radical with olefins was carried out using the RRKM program. Kinetic experiments on reactions of phenyl radical (C{sub 6}H{sub 5}) with O{sub 2} and NO{sub 2} gave preliminary results. Data are being analyzed for shock tubes studies of the reaction of benzene with O atoms. Studies of CH{sub 3}O reactions are underway.

Kinetics modeling and interpretation of experimental results for XeF. Annual report, December 1985--November 1986

Description: In this report the author presents a detailed discussion of a computer model of the electron beam pumped XeF laser which was developed for Los Alamos National Laboratory during FY86. In its present form, it should provide useful modeling and scaling of XeF laser experiments currently of interest. Additional modifications will be required for long pulse (t{sub P}>5{mu}sec) simulations. The model includes all of the important energy transport processes which contribute to the formation and quench… more

Kriging for interpolation of sparse and irregularly distributed geologic data

Description: For many geologic problems, subsurface observations are available only from a small number of irregularly distributed locations, for example from a handful of drill holes in the region of interest. These observations will be interpolated one way or another, for example by hand-drawn stratigraphic cross-sections, by trend-fitting techniques, or by simple averaging which ignores spatial correlation. In this paper we consider an interpolation technique for such situations which provides, in additi… more

Methods for environmental monitoring of DOE waste disposal and storage sites. Semiannual progress report, April 1--September 30, 1986

Description: Sulfate-reducing bacteria were grown in media containing (1) mercury and (2) a mixture of heavy metals to determine if these bacteria could effectively precipitate heavy metals from an aqueous solutions. Previous studies have shown that (1) sulfate-reducing bacteria produce hydrogen sulfide and (2) that hydrogen sulfide reacts with various heavy metals producing insoluble complexes. Data from these studies showed that when bacteria were incubated with heavy metals for 2 to 4 days a marked decre… more
