Data analysis and management for the Uranium Resource Evaluation Project

Description: The Department of Energy has funded a large data collection effort with the purpose of determining the US uranium resources. This Uranium Resource Evaluation (URE) Project required a large data management effort which involved collection, retrieval, processing, display, and analysis of large volumes of data. Many of the characteristics of this data processing system are relevant to other applications, particularly where routine processing involves analyses for input into numerous technical repo… more

Geostatistics project of the national uranium resource evaluation program. Progress report, October 1979-March 1980

Description: During the period covered by this report, the authors investigated the serial properties of aerial radiometric data. Results were applied to the choice of minimum segment width in the maximum variance segments algorithm and to the use of aerial radiometric data in the design of ground sampling experiments. The report also presents the results of a comparison of normal and lognormal percentile estimation techniques. Twenty-two quadrangles are being analyzed in the search for a uranium favorabili… more

Radiation dosimetry through spectral definition

Description: We have developed a fieldable instrumentation system for determining from measured flux spectra, both the neutron and gamma ray dose rate distributions associated with radioactive sources. This system includes the sensors, the computer-based data acquisition and analysis hardware, and the requisite software for unfolding the sensor response functions to obtain the flux spectra, and for folding the resultant flux spectra with appropriate flux spectrum-to-dose conversion factors. We use bismuth g… more

Gravity survey of the Escalante Desert and vicinity, in Iron and Washington Counties, Utah

Description: During the summers of 1978 and 1979, a total of 436 new gravity stations were taken in the southern part of the Escalante Desert and vicinity in Iron and Washington counties, Utah. The new stations were combined with 917 other stations taken in previous surveys, and a total of 1353 stations were used in this study, covering an area of about 2700 mi/sup 2/ (7000 km/sup 2/). The purpose of the study was to help evaluate the potential of geothermal resources within the survey area, which includes … more

Uncertainty in the power distribution for a fast reactor burnup cycle

Description: Demonstration that advanced reactor designs satisfy safety and performance goals requires the analysis of uncertainties in calculated reactor characteristics. Two of the important performance characteristics of advanced liquid metal reactors (LMR) are the burnup reactivity swing and the local power peaking factor. Previous work reported a study of the uncertainty in the burnup reactivity swing attributable to nuclear data uncertainties for a typical advanced LMR design. The results are reported… more

Automated computer analysis of plasma-streak traces from SCYLLAC

Description: An automated computer analysis technique that locates and references the approximate centroid of single- or dual-streak traces from the Los Alamos Scientific Laboratory SCYLLAC facility is described. The technique also determines the plasma-trace width over a limited self-adjusting region. The plasma traces are recorded with streak cameras on Polaroid film, then scanned and digitized for processing. The analysis technique uses scene segmentation to separate the plasma trace from a reference fid… more

Magnetic fusion energy and computers

Description: The application of computers to magnetic fusion energy research is essential. In the last several years the use of computers in the numerical modeling of fusion systems has increased substantially. There are several categories of computer models used to study the physics of magnetically confined plasmas. A comparable number of types of models for engineering studies are also in use. To meet the needs of the fusion program, the National Magnetic Fusion Energy Computer Center has been established… more

CDC 7600 LTSS programming stratagens: preparing your first production code for the Livermore Timesharing System

Description: This report deals with some techniques in applied programming using the Livermore Timesharing System (LTSS) on the CDC 7600 computers at the National Magnetic Fusion Energy Computer Center (NMFECC) and the Lawrence Livermore Laboratory Computer Center (LLLCC or Octopus network). This report is based on a document originally written specifically about the system as it is implemented at NMFECC but has been revised to accommodate differences between LLLCC and NMFECC implementations. Topics include… more

Instrument for observing transient cosmic gamma-ray sources for the ISEE-C Heliocentric spacecraft

Description: Satellite instrumentation that would serve as one element of a three-satellite network to provide precise directional information for the recently discovered cosmic gamma-ray bursts is described. The proposed network would be capable of determining source locations with uncertainties of less than one arc minute, sufficient for a meaningful optical and radio search. The association of the gamma bursts with a known type of astrophysical object provides the most direct method for establishing sour… more

GRPANL: a program for fitting complex peak groupings for gamma and x-ray energies and intensities

Description: GRPANL is a general-purpose peak-fitting program that calculates gamma-ray and x-ray energies and intensities from a given spectral region. The program requires that the user supply input information such as the first and last channels of the region, the channels to be used as pre- and post-region background, the system gain and zero-intercept, and a list of approximate energy values at which peaks occur in the region. Because the peak position and peak-shape parameters enter nonlinearly into t… more

(Intrusion Path Analysis)

Description: The design and implementation of an Intrusion Path Analysis (IPA) function came about as a result of the upgrades to the security systems at the Savannah River Site (SRS), near Aiken, South Carolina. The stated requirements for IPA were broad, leaving opportunity for creative freedom during design and development. The essential elements were that it: be based on alarm and sensor state data; consider insider as well as outsider threats; be flexible and easily enabled or disabled; not be processo… more

Digital neutron radiography using plane converters with multiwire proportional chambers

Description: The work described here was completed more than three years ago, and represents, in large part the PhD and MS thesis research of two of the present authors. Much of it has been reported previously elsewhere. It constitutes an effort to develop and study a moderately low cost, moderate resolution, high sensitivity, on-line method for digital neutron radiography, intended for use where neutron fluence was limited by source strength, or received dose. The basic imaging system consisted of a positi… more

Performance programming with the Los Alamos macro accelerator

Description: The CCC macro facility, as extended by Version 2.0 of Softool's Change and Configuration Control Environment, offers many new and powerful features. Among these are a vastly extended suite of commands, error trapping, and structured constructs. In concert with previously existing Version 1.x features (notably the very powerful symbol substitution and parameter passage facilities), these features combine to transform the macro facility from a simple command language into an extremely flexible pr… more
