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 … more

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 d… more

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 th… more

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 cor… more

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 … more

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 … more

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 an… more

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 presen… more
