Trends in exploration and exploration equipment for uranium

Description: Uranium exploration once again is in a ''boom'' cycle. The energy needs of the OPEC and non-OPEC countries alike have created a demand for uranium which appears certain to increase in future years. In turn, this demand has stimulated a dramatic rise in both the price of uranium and the exploration activity necessary to discover new reserves. One immediate reaction to the sudden increase in uranium exploration activity has been the evaluation of old exploration methods and equipment. This paper … more

Regional transport model of atmospheric sulfates

Description: A regional transport model of atmospheric sulfates was developed. This quasi-Lagrangian three-dimensional grid numerical model uses a detailed SO/sub 2/ emission inventory of major anthropogenic sources in the eastern U.S. region and observed meteorological data during an episode as inputs. The model accounts for advective transport and turbulent diffusion of the pollutants. The chemical transformation of SO/sub 2/ and SO/sub 4//sup 2 -/ and the deposition of the species at the earth's surface … more

Moving head disc operating system on an 854A automatic network analyzer

Description: The increased work load on the 8542A Automatic Network Analyzer revealed a need for a more efficient and flexible system to support measurement as well as software development projects. A search for such a system resulted in the choice of the moving head disc operating system (DOS-M). The conversion of the ANA operating system to DOS-M enhanced the operation and efficiency of the 8542A ANA. 5 figures.

Comments on mutagenesis risk estimation

Description: Several hypotheses and concepts have tended to oversimplify the problem of mutagenesis and can be misleading when used for genetic risk estimation. These include: the hypothesis that radiation-induced mutation frequency depends primarily on the DNA content per haploid genome, the extension of this concept to chemical mutagenesis, the view that, since DNA is DNA, mutational effects can be expected to be qualitatively similar in all organisms, the REC unit, and the view that mutation rates from c… more

The Approach to Scaling in Single Particle Inclusive Hadron Scattering from 4-GeV/c to 250 GeV/c

Description: Measurements of the dependence on s = (p{sub a} + p{sub b}){sup 2} of the cross section for single charged hadron production in the reactions a + b {yields} c + anything are presented. Particle c is detected in a fixed interval of laboratory momentum and angle in the fragmentation region of the target proton. For the energy range studied there are significant departures from A + Bs{sup -1/2} energy dependence. When these departures are taken into account, asymptotic predictions such as Pomeron … more

Measurement of y-Distributions for High Energy Antineutrino Scattering in Hydrogen-Neon

Description: Distributions in the scaling variable y are presented based on a study of approximately 700 antineutrino events in the energy range 10-200 GeV obtained using the Fermilab 15-ft bubble chamber filled with a light Hydrogen-Neon mixture. The distributions are inconsistent with a (1 -y){sup 2} form predicted by the simple quark parton model of the nucleon without antiquarks, but can be well fitted assuming a relative antiquark contribution of (10 {+-} 5)%. For small values of the Bjorken scaling va… more

Search for anti-neutrino induced muon+ e- events

Description: The authors have examined 1200 interactions with visible energies greater than 7.5 GeV produced by an anti-neutrino beam in the Fermilab 15-foot bubble chamber filled with a light neon hydrogen mixture. They have found one event with a {mu}{sup +}e{sup -} and hadrons in the final state, but with no evidence of strange particle production. This event may be an example of dilepton production by an anti-neutrino interaction, but other interpretations are possible. With 90% confidence, they conclud… more

Molecular Mechanisms of Scale Deposition

Description: Scales do not develop equally on different substrates, even when bulk physicochemical conditions are the same. The reason for these differential developments, one must presume, are due to subtle features of the near-surface region, either composition or structure. They intend to focus their studies on the structural aspects, including concerns about the molecular structures of solvated components that may be involved with the surface reactions. This approach is richly mechanistic in outlook. It… more

Preliminary conceptual design of commercial geopressured geothermal fuel plants

Description: Previous feasibility studies Bechtel (1975), TRW (1975) for electric power generation utilizing geothermal resources have tended to focus primarily on the power plant and have neglected the fuel production and effluent disposal facilities. The Dow Chemical USA study (1974) for the Governor's Energy Advisory Council, State of Texas, placed equal emphasis on the power plant and the fuel plant. The study reported in Chapter II and in what follows in this chapter, also places equal emphasis on the … more

Preliminary Conceptual Design of Commercial Geopressured Geothermal Electricity Generation Plants

Description: The geopressured geothermal resource is an unproven, poorly characterized resource. For this reason, detailed designs of utilization facilities are neither desired nor justifiable at this time. However, an overall preliminary design study, the purpose of which is to establish a baseline for technical, net energetic, and economic assessment, is justified. Clearly, if overwhelming technical, net energetic, or economic problems can be identified during the basic planning phase for a project, then … more

Brine disposal

Description: Two issues pervade all of geothermal fluids utilization--the resource and the economics of producing and utilizing it and the effluent and the economics of disposing of it in an environmentally acceptable manner. Clearly, the resource must be available; its availability, however, will not be attractive unless the effluents can be disposed of economically. The purpose of this chapter is to discuss the accumulated evidence concerning disposal alternatives from the standpoint of technology, econom… more

Computational methods for estimating precipitation from geothermal brines

Description: Laboratory experiments using Salton Sea Geothermal Field brines at elevated temperatures are costly, time-consuming, and potentially difficult to perform. The LLL Geothermal Program is therefore also attempting to predict equilibria in the SSGF brines by computation. Two approaches to this problem are being taken. Modeling of chemical reactions in the brines is being carried out using the Helgeson-Herrick (HH) code. In addition, the precipitation of many solids is being studied individually usi… more
