The GNEMRE Dendro Tool. (open access)

The GNEMRE Dendro Tool.

The GNEMRE Dendro Tool provides a previously unrealized analysis capability in the field of nuclear explosion monitoring. Dendro Tool allows analysts to quickly and easily determine the similarity between seismic events using the waveform time-series for each of the events to compute cross-correlation values. Events can then be categorized into clusters of similar events. This analysis technique can be used to characterize historical archives of seismic events in order to determine many of the unique sources that are present. In addition, the source of any new events can be quickly identified simply by comparing the new event to the historical set.

Early history of the Fermilab Main Ring (open access)

Early history of the Fermilab Main Ring

This note is written in response to a request from Phil Livdahl for corrections, and additions to a TM he is writing on Staffing Levels at Fermilab during Initial Construction Years and to a note that Hank Hinterberger is preparing on milestones. In my spare time over the past few years I have taken the original files of the Main Ring Section, my own notes from that period, and various other collections of relevant paper, and arranged them in a set of 44 large loose leaf binders in chronological order. I call this set of volumes the 'Main Ring Chronological Archives'. In response to Phil's request I have recently skimmed through these records of the period and extracted a small subset of documents which relate to the specific questions that Phil is addressing: staffing. administration, and milestones.

Low-pressure approach to the formation and study of exciplex systems. [For CDC 7600] (open access)

Low-pressure approach to the formation and study of exciplex systems. [For CDC 7600]

Studies on the formation and properties of new materials for high-energy, gas-phase lasers are described. Attention is directed mainly to systems having bound excited states but unbound ground states. An important class of such excimer/exciplex systems has a van der Waals dimer/oligomer as its ground state. This research attempts to probe the relative rates of electron pumping of excited-state manifolds and the preferentially pumped vibronic states within each manifold. Reactive quenching of emission, resonant self-absorption of laser emissions, and collision- and noncollision-induced intersystem crossing are also considered. Lists of personnel and facilities are included. 8 figures, 2 tables. (RWR)

Overheating in Hot Water- and Steam-Heated Multifamily Buildings (open access)

Overheating in Hot Water- and Steam-Heated Multifamily Buildings

Apartment temperature data have been collected from the archives of companies that provide energy management systems (EMS) to multifamily buildings in the Northeast U.S. The data have been analyzed from more than 100 apartments in eighteen buildings where EMS systems were already installed to quantify the degree of overheating. This research attempts to answer the question, 'What is the magnitude of apartment overheating in multifamily buildings with central hot water or steam heat?' This report provides valuable information to researchers, utility program managers and building owners interested in controlling heating energy waste and improving resident comfort. Apartment temperature data were analyzed for deviation from a 70 degrees F desired setpoint and for variation by heating system type, apartment floor level and ambient conditions. The data shows that overheating is significant in these multifamily buildings with both hot water and steam heating systems.

Hanford Meteorological Station computer codes: Volume 5, The TOWER computer code (open access)

Hanford Meteorological Station computer codes: Volume 5, The TOWER computer code

The Hanford Meteorological Station (HMS), operated by Pacific Northwest Laboratory, archives wind, dry bulb temperature, and soil temperature data gathered each hour from the 410-ft meteorological tower. These data include measurements of wind speed and wind direction for seven heights, eight dry bulb temperatures, and three soil temperatures. The TOWER computer code is used to archive those measurements and apply quality assurance checks to the data. The code accesses an input file, which contains the previous archive's date and hour, and an output file, which contains tower weather observations for the current month. A data entry form consisting of 25 fields is included in the program. The fields must be filled in by the user. The information entered is appended to the monthly file, which provides an archive for the tower data gathered hourly. This volume describes the implementation and operation of the TOWER computer code at the HMS.

An updated global grid point surface air temperature anomaly data set: 1851--1990 (open access)

An updated global grid point surface air temperature anomaly data set: 1851--1990

This document presents land-based monthly surface air temperature anomalies (departures from a 1951--1970 reference period mean) on a 5{degree} latitude by 10{degree} longitude global grid. Monthly surface air temperature anomalies (departures from a 1957--1975 reference period mean) for the Antarctic (grid points from 65{degree}S to 85{degree}S) are presented in a similar way as a separate data set. The data were derived primarily from the World Weather Records and the archives of the United Kingdom Meteorological Office. This long-term record of temperature anomalies may be used in studies addressing possible greenhouse-gas-induced climate changes. To date, the data have been employed in generating regional, hemispheric, and global time series for determining whether recent (i.e., post-1900) warming trends have taken place. This document also presents the monthly mean temperature records for the individual stations that were used to generate the set of gridded anomalies. The periods of record vary by station. Northern Hemisphere station data have been corrected for inhomogeneities, while Southern Hemisphere data are presented in uncorrected form. 14 refs., 11 figs., 10 tabs.

Effects of shear and roughness on vortex sheeding patterns behind a circular cylinder at critical Reynolds numbers (open access)

Effects of shear and roughness on vortex sheeding patterns behind a circular cylinder at critical Reynolds numbers

This test program was undertaken to further the understanding of vortex shedding patterns to be experienced by the OTEC Cold Water pipe. The present series of tests was planned to incorporate improvements in design of the previously used test model and data gathering capability in order to achieve certain results which the previous program was unable to achieve. Specifically, three goals were envisioned: (1) determination of eddy shedding correlation lengths as a function of upstream shear. Improved endplate design and larger aspect ratio were the chief steps taken toward attaining this objective. (2) Determination of minimum shear level producing cellular shedding patterns. A wider range of upstream velocity shears was to be tested than in any previous study. (3) Detailed analysis of the effect of roughness on shedding patterns. A very smooth cylinder was to be tested under the same conditions as a roughened cylinder, and the two sets of results compared. Two weeks of wind tunnel testing were scheduled to perform the tests. The first week was allotted to the roughened cylinder, and the second week was devoted to examining the smooth cylinder. The experimental setup and procedures are described, and results are presented and discussed. (WHK)

CdSiAs/sub 2/ thin films for solar cell applications. Second quarter report, July 1, 1979-September 30, 1979. [CdSiAs/sub 2//CdS]

Sputtered films have been formed with two improved composite (Si + CdAs/sub 2/) targets. Near stoichiometric and mechanically continuous CdSiAs/sub 2/ films have been formed on metal substrates. Films of this type will be used over the next reporting period for heterojunction formation. Evaporation studies related to CdAs/sub 2/ have been completed. Stoichiometric CdAs/sub 2/ films could not be formed by means of single-source evaporation of CdAs/sub 2/ bulk. Hence, this dual source approach (Si + CdAs/sub 2/) does not appear feasible with the techniques used thus far. Electron beam microprobe elemental analysis has been improved by changing from a GaAs standard to one of SiAs. The latter standard is more directly applicable to the compounds being measured. Accuracy of elemental composition measurements by means of the microprobe are estimated to be about +- 0.1 atomic percent. A CdS/CdSiAs/sub 2/ junction was formed on bulk CdSiAs/sub 2/. This junction gives a good diode curve (no shunting or series resistance problems), although very poor photovoltaic response. Heterojunction formation and gridding procedure have been established.

Atlas of experimentally-induced neoplasia in beagle dogs (open access)

Atlas of experimentally-induced neoplasia in beagle dogs

Beagle dogs have been utilized extensively in biomedical research. The US Department of Energy`s (DOE) Office of Health and Environmental Research (OHER) has sponsored life-span dose-effect radiation studies in beagles at various laboratories. Because results from studies in the various laboratories were to be compared, all the investigators strove to use similar nomenclature and criteria to describe biological effects. For this reason, pathologists from these laboratories met on five occasions between 1976 and 1977 to discuss nomenclature and histologic criteria for diagnoses. At these meeting, criteria were discussed for histopathologic description of lesions in bone, liver, lung, hematopoietic and lymphoid tissues, mammary gland, pituitary, testis, and thyroid. To provide further assurance of cooperation among the DOE laboratories involved, DOE organized several Task Groups in 1985, composed of staff members from the laboratories. The Task Group on Biological Effects was asked to standardize nomenclature and diagnostic criteria for pathology; this beagle pathology atlas is the result of that request. The atlas describes target organs of particular interest: lungs for radionuclides delivered by inhalation; bones for bone-seeking radionuclides; and hematopoietic and other soft tissues for external irradiation.

Advisory Committee on human radiation experiments final report (open access)

Advisory Committee on human radiation experiments final report

When the Advisory Committee began work in April 1994 we were charged with determining whether the radiation experiments design and administration adequately met the ethical and scientific standards, including standards of informed consent, that prevailed at the time of the experiments and that exist today and also to determine the ethical and scientific standards and criteria by which it shall evaluate human radiation experiments. Although this charge seems straightforward, it is in fact difficult to determine what the appropriate standards should be for evaluating the conduct and policies of thirty or fifty years ago. First, we needed to determine the extent to which the standards of that time are similar to the standards of today. To the extent that there were differences we needed to determine the relative roles of each in making moral evaluations. In Chapter 1 we report what we have been able to reconstruct about government rules and policies in the 1940s and 1950s regarding human experiments. We focus primarily on the Atomic Energy Commission and the Department of Defense. In Chapter 2 we turn from a consideration of government standards to an exploration of the norms and practices of physicians and medical scientists who conducted research …

Global Nuclear Energy Partnership Programmatic Environmental Impact Statement (open access)

Global Nuclear Energy Partnership Programmatic Environmental Impact Statement

Abstract: The proposed Global Nuclear Energy Partnership (GNEP) Program, which is part of the President’s Advanced Energy Initiative, is intended to support a safe, secure, and sustainable expansion of nuclear energy, both domestically and internationally. Domestically, the GNEP Program would promote technologies that support economic, sustained production of nuclear-generated electricity, while reducing the impacts associated with spent nuclear fuel disposal and reducing proliferation risks. The Department of Energy (DOE) proposed action envisions changing the United States nuclear energy fuel cycle from an open (or once-through) fuel cycle—in which nuclear fuel is used in a power plant one time and the resulting spent nuclear fuel is stored for eventual disposal in a geologic repository—to a closed fuel cycle in which spent nuclear fuel would be recycled to recover energy-bearing components for use in new nuclear fuel. At this time, DOE has no specific proposed actions for the international component of the GNEP Program. Rather, the United States, through the GNEP Program, is considering various initiatives to work cooperatively with other nations. Such initiatives include the development of grid-appropriate reactors and the development of reliable fuel services (to provide an assured supply of fresh nuclear fuel and assist with the management of …

Existing climate data sources and Their Use in Heat IslandResearch (open access)

Existing climate data sources and Their Use in Heat IslandResearch

Existing climate data sources can be used in two general types of analysis for the detection of urban heat islands. Historical analyses use long-term data records-preferentially from several locations in and around an urban area-to trace the gradual influence of urban development on its climate. Primary sources of such data include the cooperative network, first-order National Weather Service stations, and military weather stations. Analyses of short-term data use information from a dense urban weather station network to discern the location, extent, and magnitude of urban heat islands. Such analyses may use the aforementioned national networks or regional networks such as agricultural, air quality monitoring, or utility networks. We demonstrate the use of existing data sources with a historical analysis of temperature trends in Los Angeles, California, and an analysis of short-term data of the urban temperature profile for Phoenix, Arizona. The Los Angeles climate was examined with eleven long-term data records from the cooperative network. Statistically significant trends of rising temperature were detected at Los Angeles Civic Center and other stations over some parts of the year, although timing of the increase varied from station to station. Observed increases in temperatures maybe due to long-term climate changes, microclimate influences, or …

Preserving Ultra-Pure Uranium-233 (open access)

Preserving Ultra-Pure Uranium-233

Uranium-233 ({sup 233}U) is a synthetic isotope of uranium formed under reactor conditions during neutron capture by natural thorium ({sup 232}Th). At high purities, this synthetic isotope serves as a crucial reference material for accurately quantifying and characterizing uranium-bearing materials assays and isotopic distributions for domestic and international nuclear safeguards. Separated, high purity {sup 233}U is stored in vaults at Oak Ridge National Laboratory (ORNL). These materials represent a broad spectrum of {sup 233}U from the standpoint of isotopic purity - the purest being crucial for precise analyses in safeguarding uranium. All {sup 233}U at ORNL is currently scheduled to be disposed of by down-blending with depleted uranium beginning in 2015. This will reduce safety concerns and security costs associated with storage. Down-blending this material will permanently destroy its potential value as a certified reference material for use in uranium analyses. Furthermore, no credible options exist for replacing {sup 233}U due to the lack of operating production capability and the high cost of restarting currently shut down capabilities. A study was commissioned to determine the need for preserving high-purity {sup 233}U. This study looked at the current supply and the historical and continuing domestic need for this crucial isotope.
