Equipment qualification research program: program plan (open access)

Equipment qualification research program: program plan

The Lawrence Livermore National Laboratory (LLNL) under the sponsorship of the US Nuclear Regulatory Commission (NRC) has developed this program plan for research in equipment qualification (EQA). In this report the research program which will be executed in accordance with this plan will be referred to as the Equipment Qualification Research Program (EQRP). Covered are electrical and mechanical equipment under the conditions described in the OBJECTIVE section of this report. The EQRP has two phases; Phase I is primarily to produce early results and to develop information for Phase II. Phase I will last 18 months and consists of six projects. The first project is program management. The second project is responsible for in-depth evaluation and review of EQ issues and EQ processes. The third project is responsible for detailed planning to initiate Phase II. The remaining three projects address specific equipment; i.e., valves, electrical equipment, and a pump.

Present capabilities and new developments in antenna modeling with the numerical electromagnetics code NEC (open access)

Present capabilities and new developments in antenna modeling with the numerical electromagnetics code NEC

Computer modeling of antennas, since its start in the late 1960's, has become a powerful and widely used tool for antenna design. Computer codes have been developed based on the Method-of-Moments, Geometrical Theory of Diffraction, or integration of Maxwell's equations. Of such tools, the Numerical Electromagnetics Code-Method of Moments (NEC) has become one of the most widely used codes for modeling resonant sized antennas. There are several reasons for this including the systematic updating and extension of its capabilities, extensive user-oriented documentation and accessibility of its developers for user assistance. The result is that there are estimated to be several hundred users of various versions of NEC world wide. 23 refs., 10 figs.

Laboratory procedures used in the hot corrosion project (open access)

Laboratory procedures used in the hot corrosion project

The objective of the Hot Corrosion Project in the LLNL Metals and Ceramics Division is to study the physical and chemical mechanisms of corrosion of nickel, iron, and some of their alloys when these metals are subjected to oxidizing or sulfidizing environments at temperatures between 850 and 950/sup 0/C. To obtain meaningful data in this study, we must rigidly control many parameters. Parameters are discussed and the methods chosen to control them in this laboratory. Some of the mechanics and manipulative procedures that are specifically related to data access and repeatability are covered. The method of recording and processing the data from each experiment using an LS-11 minicomputer are described. The analytical procedures used to evaluate the specimens after the corrosion tests are enumerated and discussed.

Environmental geology workshop for the Geysers--Calistoga known geothermal resources area (open access)

Environmental geology workshop for the Geysers--Calistoga known geothermal resources area

Lawrence Livermore Laboratory (LLL) is studying ways in which the environmental quality of The Geysers-Calistoga known geothermal resources area may be protected from any significant harmful consequences of future geothermal development. The LLL study includes the effects of development on air and water quality, geology, the ecosystem, socioeconomics, and noise. The Geothermal Resource Impact Projection Study (GRIPS) has grants to undertake similar work. On 28 and 29 November 1977, LLL and GRIPS jointly sponsored a workshop at Sonoma State College at which knowledgeable earth scientists presented their views on the potential geological hazards of geothermal development. The workshop produced recommendations for studies in geological mapping, slope stability, subsidence, seismicity, and groundwater hydrology. These recommendations will be evaluated along with other considerations and in conjunction with the other subjects of the LLL study. The results of the study will be contained in a preplanning report of final recommendations to the Department of Energy.

Near-Term Hybrid Vehicle Program, Phase I. Appendix D. Sensitivity analysis report. Final report

The study methodology, the selection of input parameters and output variables, the sensitivity study results, and the conclusions of the sensitivity analysis for the Near-Term Hybrid Vehicle (NTHV) Program are presented. The objective of the Sensitivity Analysis was to determine the impact of variations in selected parameters on the utility, the economic attractiveness, and the marketability of the hybrid vehicle. The parameters to be varied include travel characteristics, energy costs, hybrid vehicle lifetime, maintenance costs, and fuel economy of the Reference ICE Vehicle. The results of the study are presented in terms of how the design variables affect each of these aspects of the NTHV. (LCL)

Soft-sphere model for liquid metals (open access)

Soft-sphere model for liquid metals

A semi-empirical soft-sphere model of fluids is modified for application to the thermodynamic properties of liquid metals. Enthalpy, volume, and sound speed are computed as functions of temperature for 13 metals and compared with experimental data. Critical points and coexistence curves are also computed and compared with experimental data, where these have been measured. Strengths and weaknesses of the model are discussed.

EPFL (Swiss) fusion-fission hybrid experiment. Progress report, November 1, 1981-January 31, 1982

The trip provided an opportunity for extensive discussions with the staff of the Institut de Genie Atomique (IGA) of the Ecole Polytechnique Federale de Lausanne (EPFL). The discussions covered both the planning of the first series of experiments to be performed in the Hybrid Experiment (hereafter referred to as LOTUS) and the status of calculational work being performed at the University of Washington in support of the LOTUS project.

Calibration of a neutron log in partially saturated media IV: effects of sonde-wall gap (open access)

Calibration of a neutron log in partially saturated media IV: effects of sonde-wall gap

A gap between a neutron sonde and the wall of a borehole can have a significant effect on the observed count rate. This effect was determined experimentally to be linear with gaps as large as 2.5 cm. The count rate is given by N/sub N/ = K/sub 0/ + K/sub 1/g where K/sub 0/ is the count rate that would be observed at zero gap, and g is the gap. The parameters K/sub 0/ and K/sub 1/ are dependent on both water (ie. hydrogen) content and bulk density. In many situations failure to correct the count rate for this gap effect can result in a significant degradation in the accuracy of the water content calculated from the count rate. In a dry borehole, K/sub 1/ is small at zero formation water content, and increases with formation water content. In a water-filled borehole, K/sub 1/ is large at zero formation water content, and tends to decrease with increasing formation water content, becoming zero, as of course it must, if the formation is pure water. The absolute value of K/sub 1/ increases with increasing density. A representation was determined for K/sub 0/ and K/sub 1/ from experimental data. This representation can be …
