Analysis of end-use electricity consumption during two Pacific Northwest cold snaps

Description: The Pacific Northwest has experienced unusually cold weather during two recent heating seasons. Hourly end-use load data was collected from a sample of residential and commercial buildings during both cold snaps. Earlier work documented the changes in end-use load shapes as outdoor temperature became colder. This paper extends analysis of cold snap load shapes by comparing results from both cold snaps, exploring the variability of electricity consumption between sites, and describing the use of… more

Analysis of organic sulfur and nitrogen in coal via tandem degradation methods. [Quarterly] technical report, 1 March--31 May 1992

Description: Sporinite, vitrinite and semi-fusinite single macerals were separated from the IBC 101 coal by the density gradient technique. In addition, a gel permeation chromatography (GPC) system was assembled and the GPC column calibrated with four polystyrene molecular weight standards. A variety of sulfur compounds were identified in the dichromate oxidation products of the IBC 101 coal, including a thiazole and isomers of C2-, C3- and C4-alkyl thiophene carboxylic acids. Precise agreement between GC-M… more

Analysis of the superconducting wiggler magnets for the ATF Harmonic Generation FEL experiment

Description: In this paper, we consider the superconducting wiggler magnet under construction for the High Gain Harmonic Generation experiment (HGHG) at the Accelerator Test Facility (ATF) at BNL. This wiggler consists of an energy modulation section, a dispersion magnet and a radiator section. We present an analysis of the dispersion magnet and the end effects in the other wiggler sections. The purpose of the dispersion magnet is to convert energy modulation of the electron beam into spatial bunching. For … more

Anticipated soil selenium concentrations at Kesterson Reservoir

Description: Temporal trends from soil monitoring data collected at Kesterson Reservoir have been reviewed to shed light on anticipated concentrations of total and water-extractable selenium in surface and subsurface soils. Based on these data, a mass balance model for selenium has been developed and employed to evaluate the rate of leaching, remobilization and volatilization that has occurred since the Reservoir was dried out in 1987. Results from a series of calibration runs were then extrapolated 25 year… more

Applicability of trends in nuclear safety analysis to space nuclear power systems

Description: A survey is presented of some current trends in nuclear safety analysis that may be relevant to space nuclear power systems. This includes: lessons learned from operating power reactor safety and licensing; approaches to the safety design of advanced and novel reactors and facilities; the roles of risk assessment, extremely unlikely accidents, safety goals/targets; and risk-benefit analysis and communication.

Application of characteristic time concepts for hydraulic fracture configuration design, control, and optimization

Description: The analysis of pertinent energy components or affiliated characteristic times for hydraulic stimulation processes serves as an effective tool for fracture configuration designs optimization, and control. This evaluation, in conjunction with parametric sensitivity studies, provides a rational base for quantifying dominant process mechanisms and the roles of specified reservoir properties relative to controllable hydraulic fracture variables for a wide spectrum of treatment scenarios. Results ar… more

Area detectors for neutron protein crystallography

Description: The main problem in neutron protein crystallography is the low flux of present reactor based or pulsed neutron sources. This low flux is however well matched with presently available multiwire area detectors. One way to increase the flux at the sample is to increase the wavelength bandwidth. The conventional technique uses a monochromator with a bandwidth of the order of 1%. This bandwidth can be increased by using a multilayer monochromator composed of different ``d`` spacings. This provides a… more

An assessment of alternatives and technologies for replacing ozone- depleting substances at DOE facilities

Description: Title VI of the Clean Air Act, as amended, mandates a production phase-out for ozone-depleting substances (ODSs). These requirements will have a significant impact on US Department of Energy (DOE) facilities. Currently, DOE uses ODSs in three major activities: fire suppression (halon), refrigeration and cooling (chlorofluorocarbons [CFCs]), and cleaning that requires solvents (CFCs, methyl chloroform, and carbon tetrachloride). This report provides basic information on methods and strategies to… more

An assessment of potential risk resulting from a maximum credible accident scenario at the proposed explosive waste storage facility (EWSF)

Description: Lawrence Livermore National Laboratory (LLNL) proposes to build, permit, and operate a storage facility for explosive wastes at LLNL`s Explosive Test Site, Site 300. The facility would consist of four existing magazines, four new magazettes (small concrete vaults), and a new prefabricated metal building. Ash from on-site treatment of explosive waste would also be stored in the prefabricated metal building prior to sampling analysis, and shipment. The magazettes would be installed at each magazi… more

Atomistic studies of grain boundaries in alloys and compounds. Progress report, July 1990--October 1992

Description: Atomic structure and atomic level properties of grain boundaries in binary alloys have been studied theoretically. Both ordered and disordered alloys were investigated with the aim responsible for the physical and mechanical properties differing from pure metals. An integral part is atomic interactions. The first are the many-body potentials akin to the embedded atom method. The most important potentials for Cu-Bi which combined empirical data and ab initio electronic structure calculations to … more

An autonomous expendable conductivity, temperature, depth profiler for ocean data collection

Description: An Autonomous Expendable Conductivity-Temperature-Depth Profiler (AXCTD) for profiling temperature, conductivity, pressure, and other parameters in remote oceanic regions is described. The AXCTD is a microcomputer-controlled sensor package that can be deployed by unskilled operators from ships or aircraft. It records two CTD profiles (one during descent and another during ascent) and CTD times series while on the bottom and adrift at the surface. Recorded data are transmitted to an ARGOS satell… more
