This study was undertaken to provide a summary of wind data from nuclear power plant sites. National Weather Service archives are an immediately obvious source of wind data, but additional data sources are also available. Utility companies proposing to build nuclear power plants are required to establish on-site meteorological monitoring programs that include towers for collecting wind and temperature data for use in environmental impact assessments. These data are available for more than one hundred planned or operating nuclear power plant sites This site wind data provides a valuable addition to the existing NWS data sets, and significantly enlarges the multilevel data presently available. The wind data published through the NRC is assembled and assessed here in order to provide a supplement to existing data sets.

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)

Four recent measurements in pp and np scattering below 250 MeV are used to indicate the substantial influence that new experiments can have upon phase parameters derived from the expanded data base. The cases are described separately, and the collective effect upon energy dependent analyses is discussed. It is indicated that the types of change are far from negligible. 7 refs. (JFP)

The objective of this research is to develop and apply targeting procedures for the evaluation of low-temperature radiogenically-derived geothermal resources in the eastern United States utilizing geological, geochemical, and geophysical data. Detailed study of the Liberty Hill and Winnsboro plutons, South Carolina, is continuing in order to provide insight into the behavior of uranium and thorium in unmetamorphosed granitic plutons during periods of crystallization, deuteric alteration and weathering. The importance of the oxidation state of uranium has become apparent because the transition from U/sup 4 +/ to U/sup 6 +/ represents the division between immobile and labile uranium. Accessory uraninite has been found in the Liberty Hill pluton, and molybdenite mineralization occurs in both the Liberty Hill and Winnsboro plutons. The molybdenum mineralization is present in a number of 300 m.y. granitic plutons in the southeastern U.S. A steep metamorphic gradient across the Roxboro, North Carolina, metagranite, which was metamorphosed during Devonian time, should provide a good opportunity to study the effect of prograde metamorphism on the distribution of uranium and thorium. Three holes have been drilled into the Roxboro metagranite for the purpose of examining the effect of metamorphism on heat generation and heat flow. Preliminary modeling of negative …

This report analyzes data on the health effects of bicycling in an urban environment through intensive study of ten healthy male subjects bicycling or driving in systematically varied conditions in the streets of Washington, D.C. Evaluation criteria for available technology and instrumentation are included and a methodology is developed for route selection. Specific air pollutants (carbon monoxide, ozone, sulfates, nitrates, and particulates) are measured concurrently with exposure and subsequent changes in health status identified through pulmonary function testing, cardiovascular testing, and blood and symptoms analysis. The report concludes that no major adverse short-term health effects were noted for ten healthy male subjects while bicycling or driving in levels of pollution and thermal stress encountered during the study period. Recommendations for further research are also presented.

Beryllium-copper alloys should be considered toxic materials and proper controls must be used when they are machined, heated, or otherwise fabricated. Air samples should be taken for each type of fabrication to determine the worker's exposure and the effectiveness of the controls in use. It has been shown that aerosols containing beryllium are generated during the four methods of fabrication tested, and that these aerosols can be reduced through local exhaust to undetectable levels. Considering the acute, chronic and possibly carcinogenic effects of exposure to beryllium, effective controls should be required because they are feasible both technologically and economically. The health hazards and control measures are reviewed.

First volume of a study focusing on the predictability of drowned prehistoric habitation sites in the continental shelf area.

The primary objective of the proposed research will be elucidation of the etiology and pathogenesis of bovine leukemia. We have consistently demonstrated C-type particles in mitogen stimulated lymphocyte cultures from leukemic cows and cows with a persistent lymphocytosis. These particles have been concentrated and partially purified by continuous flow, density gradient, ultracentrifugation. Newborn calves and late stage bovine fetuses have been inoculated with these concentrated cell free preparations. Our current study involves extensive monitoring of these inoculated animals to detect early pre-cancerous changes. The following parameters are being measured: the serological titer against a bovine leukemia associated antigen; the percentage of lymphocytes showing nuclear pockets; the percentage of mitogen stimulated lymphocytes with C-type particles adherent to their surface; the percentage of B-lymphocytes in the peripheral circulation; the complete blood count; and the quantity of bovine leukemia virus (BLV) production as determined by the syncytia induction assay. Additional proposals include: using the monitoring parameters to study animals with the juvenile and thymic forms of leukemia; the examination of adult lymphosarcoma cases to determine which tissues harbor BLV; and lymphocyte subpopulation work to further define which cell types are associated with BLV production and tumor formation.

This study was initiated in 1957 by the U.S. Public Health and many facets of this project are reaching final objectives. Many new studies have developed in the course of this study and will continue. The projects supported by the Energy Research and Development Administration are of utmost importance and consist of: collection of material from uranium miners known to have cancer of the lung into a tumor registry; manual on pulmonary cytology; regression study of sputum cytological findings in uranium miners who showed marked atypical squamous cell metaplasia and have quit smoking cigarettes, mining, or both; continuation of sputum collection and collection of lungs from deceased miners; sensory development for localization of carcinoma in situ of the lung; and lung histology program. Since we have examined approximately 77,000 sputum samples over the last 20 years in cases that showed normal cytology at the inception of the study and some subsequently developed carcinoma of the lung, we have an accumulation of material that is worthy of study and presentation.

During the HTGR fuel development program, a high percentage of uranium-loaded weak acid resin microspheres broke during pneumatic transfer, carbonization, and conversion. One batch had been loaded by the UO/sub 3/ method; the other by the ammonia neutralization method. To determine the causes of failure, samples of the two failed batches were investigated by optical microscopy, scanning electron microscopy, electron beam microprobe, and other techniques. Causes of failure are postulated and methods are suggested to prevent recurrence of this kind of failure.
