Influence of access hole parameters on neutron moisture probe readings

Description: Computing soil moisture content with a neutron probe requires use of a calibration curve that considers the thermal neutron capture cross section of the hole liner as well as the hole diameter. The influence of steel, polyvinyl chloride, and aluminum casings that fit 0.051 to 0.102-hole diameters was determined by comparison with neutron probe readings in uncased holes of corresponding diameters. Eccentricity of probe location was considered a potentially significant variable. The relationship between hole diameter and count rate also was investigated. The experiment was run in disturbed Bandelier tuff with an average dry density of 1.2 g . cm/sup -3/ and moisture content of 1.3 to 35.5% by volume. The casing material and hole diameter influenced the probe readings significantly, whereas eccentric location of the probe did not. Regression analyses showed an almost perfect inverse linear correlation between hole diameter and count rate.

Assessment of powdered activated carbon addition to anaerobic digesters at Salt Lake City, Utah

Description: The Salt Lake City Water Reclamation Plant has added powdered activated carbon to its influent wastewater since January 1977. Battelle Pacific Northwest Laboratory has gathered and analyzed operational data from the treatment plant in an effort to identify beneficial effects of the carbon. Benefits occurring during anaerobic digestion were of principal interest. Three potential areas of enhanced treatment were investigated: reduced solids in the primary clarifier effluent; increased anaerobic digester gas production; and increased sludge stabilization rate. Review of the data from the Salt Lake City plant indicates that carbon did not significantly affect these aspects of the plant operation. However, the carbon dose rate was generally lower than that used in other carbon addition studies. Therefore, data from Salt Lake City can be interpreted to mean only that carbon does not produce the above benefits at low doses. Potential benefits identified by other investigators using higher carbon dose rates have not been invalidated.

Extraction of tritium from liquid lithium by permeation

Description: This paper assesses a method for extracting tritium from liquid lithium for specific application to the conceptual laser fusion reactor that uses a continuous lithium ''waterfall.'' The tritium diffuses through a refractory metal that contains a getter and is then stored in a hydride-forming alloy. There are various uncertainties with this method including helium-4 extraction, unknown impurities that may accumulate in liquid lithium, the effects of these impurities on tritium separation, and the maintenance of tritium-contaminated equipment. Our study indicates that major tritium losses will occur during equipment maintenance rather than as a result of permeation losses through the primary vessel.

Liquid-fluidized-bed heat exchanger design parameters

Description: Liquid-fluidized-bed heat exchangers prevent scale accumulation on heat transfer surfaces and reduce the required heat transfer surface when scaling fluids, such as geothermal water, are used as the primary or working fluid. Liquid-fluidized-bed heat exchangers, principles of operation, and design parameters are described. Horizontal and vertical assemblies are discussed, including problems encountered with both designs. Bed-side heat transfer coefficients are given for limited cases, and a correlation is provided for calculating heat transfer coefficients for horizontal assemblies. A design example for a 60 kW/sub (e)/ (60 kW/sub (electric)/ preheater is included.

Community Systems Program: Its Goals and Accomplishments, 1978

Description: The Community Systems Program is concerned with conserving energy and scarce fuels through new methods of satisfying the energy needs of American communities. These programs are designed to develop innovative ways of combining current, emerging, and advanced technologies into Integrated Community Energy Systems (ICES) that could furnish any, or all, of the energy-using services of a community. The key goals of the Community System Program then, are to identify, evaluate, develop, demonstrate, and deploy energy systems and community designs that will optimally meet the needs of various communities. Integrated systems offer considerable potential for fuel substitution, thereby allowing the use of non-scarce fuel resources that would not be economically usable in smaller unintegrated systems. Input energy sources for such systems may include low-grade waste heat, solid and liquid wastes, solar and geothermal heat, seawater heat dissipation, and use of less-scarce fuels, such as coal and biomass. A Grid-Connected ICES uses a central co-generation plant and distribution system to provide heating, cooling, and electrical energy services. During 1977, contracts for the following Grid-Connected ICES (G-C ICES) demonstration teams were negotiated: City of Independence, Missouri; Clark University; City of Trenton, New Jersey; Health Education Authority of Louisiana (HEAL); and University of Minnesota. A coal-using ICES, proposed for Georgetown University, also has made noticeable strides toward demonstration of the concept.

Infrared absorption spectroscopy of surfaces: a low temperature thermal detection scheme

Description: A sensitive spectroscopic technique has been developed by which infrared surface absorptions are detected thermally in a sample cooled to liquid helium temperature. A tiny doped germanium thermometer attached directly to the sample crystal measures the temperature increase resulting from infrared absorption. The assembly is mounted in an ultrahigh vacuum chamber and can be repeatedly cleaned, heated, exposed to chemical reactants, and cooled to 1.5 K for spectral measurements. Preliminary data for various molecules adsorbed on evaporated metal films demonstrate that the technique is a practical means for obtaining sensitive, high resolution vibrational spectra of adsorbed molecules.

Evaluation of the General Atomic codes TAP and RECA for HTGR accident analyses

Description: The General Atomic codes TAP (Transient Analysis Program) and RECA (Reactor Emergency Cooling Analysis) are evaluated with respect to their capability for predicting the dynamic behavior of high-temperature gas-cooled reactors (HTGRs) for postulated accident conditions. Several apparent modeling problems are noted, and the susceptibility of the codes to misuse and input errors is discussed. A critique of code verification plans is also included. The several cases where direct comparisons could be made between TAP/RECA calculations and those based on other independently developed codes indicated generally good agreement, thus contributing to the credibility of the codes.

Hydrothermal alteration at the Roosevelt Hot Springs thermal area, Utah: Petrographic characterization of the alteration to 2 kilometers depth

Description: Hydrothermal alteration in drill cuttings from Thermal Power drillhole 14-2, Roosevelt Hot Springs Thermal area, has been studied petrographically. The hole is sited in alluvium approximately 1.6 km southeast of the old Resort and was rotary drilled to a depth of 1866.0 m. The exact hole location is 2310 FNL, 350 FWL, Sec. 2, Twp 27S, Rge 9W, elevation 1908.5 m. Core was extracted from 792.5 to 795.5 m. Thin sections were made from samples at 15.2 m intervals of drill cuttings collected at 1.5 or 3.0 m intervals during drilling. Thin sections were made of 1.5 or 3.0 m intervals from 274.3 to 304.8 m, 487.9 to 581.2 m, and 868.7 to 899.2 m. These intervals were chosen for close spaced sampling on the basis of increases in temperature, porosity, conductivity and acoustic velocity shown in geophysical logs. A total of 153 thin sections of cuttings were made, and an additional 9 sections were made from the core. Depths of thin section samples are listed in the appendix. A visual estimate of the percentage of each rock type was made for each thin section.

Charged and neutral current couplings of quarks (as seen by neutrinos). [Cross sections]

Description: Aspects of charged-current scattering including the question of whether the cross sections are ''anomalous'' in any sense and the subject of limits on the production of new heavy quarks are discussed. A new, unique determination of neutral-current couplings is discussed using data from deep-inelastic and elastic neutrino scatterings and from neutrino-induced exclusive and inclusive pion production. Charged-current couplings are treated in the context of the Weinberg-Salam (WS) theory of weak and electromagnetic interactions with the Glashow-Ilipoulos-Maiani (GIM) quark structure. (JFP)

Estimating population sizes in a mixture of two radioactive populations

Description: The event times are observed of a mixture of two kinds of radioactive atoms, each producing alpha particles. The probability of observing an event is p, 0 < p < 1, and of missing the observation is 1 - p. A maximum likelihood statistical method is given for estimating the size of the two populations. A second discussion assumes that the populations themselves are samples from parent populations. Bayesian methods are given for estimating parameters of the parent populations. An example is presented of an experiment involving the search for particle-bound polyneutron systems. 2 figures, 3 tables.
