Development of a unified transport approach for the assessment of power-plant impact. [Environmental impact of chemical, biological, radioactive, or thermal effluents from power plants]

Description: Progress during the first 18 months in implementation of the Unified Transport Approach (UTA) is summarized in this report, which covers the period through December 1976. The goal of this project is to develop mathematical models for fast-transient, one-and two-dimensional transport of thermal, radiological, chemical, and biological properties in rivers, estuaries, lakes, and coastal regions for assessing the impact of power-plant operations. Development and validation of these models are illus… more

Bound state momentum distributions. [PWiA]

Description: Proposed forms for nuclear momentum distributions are investigated. Calculations of (p,p') reactions using those forms are done in a PWIA at angles where the quasielastic peak is seen and also at back angles. The parameters used are derived from (e,e') data, where the nuclear momenta probed overlap with those of the low angle (p,p') experiment. Although there is reasonable agreement for the (p,p') data at 180/sup 0/, the inclusion of distortion necessitates a different parameter set to obtain a… more

Evaluation of extraction chromatography for americium recovery

Description: Extraction, or reverse-phase partition chromatography, as used mostly for analytical separations, employs an organic solvent extractant as a stationary phase on an inert support material. This technique, which has the advantage of utilizing the versatility of solvent extraction systems with the less expensive operation of ion exchange equipment, was evaluated for a process to recover low level concentrations of americium from acidic process waste streams at Rocky Flats. The bidentate organophos… more

Acceleration of partially stripped ions at the Bevalac

Description: Results are presented of the first attempts to accelerate partially stripped heavy ions in the Bevatron. Experiments were performed for hydrogen-like argon and neon ions, and, although the survival time of these ions in the 10/sup -7/ torr Bevatron vacuum was not sufficient to achieve full energy, valuable charge-changing cross section information was obtained.

Sodium tungsten bronze thin films by rf sputtering

Description: Polycrystalline Na/sub x/WO/sub 3/ films were produced by rf sputtering. Films of low x-value resulted when co-sputtering WO/sub 3/ on a Na/sub 0.83/WO/sub 3/ target, and Na/sub 0/./sub 83/ on WO/sub 3/ target. Films of high x and of mixed phase were produced by sputtering a powder mixture of Na/sub 2/WO/sub 4/ and WO/sub 3/ on a tungsten target. Of the sputtering parameters studied, the substrate temperature is the most critical with temperatures above 500/sup 0/C producing films which were cu… more

Ground Water in the Lajas Valley, Puerto Rico

Description: Abstract: Lajas Valley is plagued with problems of salinity and waterlogging the soils. Use of brackish (500 milligrams per liter) irrigation compounded ground water for the problem until an irrigation-drainage system was constructed in 1955. Lajas is an alluvium-filled limestone highlands. The alluvium, mostly clay and as much 300 feet (90 meters) thick, contains brackish ground water except in the recharge areas located along the foothills...Results from a digital model show that a network o… more

Laboratory and field studies on the long-term effects of petroleum hydrocarbons on benthic marine invertebrates

Description: Present and future activities associated with petroleum necessitate research on the potential impacts of oil in the Pacific Northwest marine environment. While the results of recent studies on the fate and effects of petroleum hydrocarbons (PHC) in the marine environment have strengthened our understanding of some aspects of oil pollution, we are not yet to the point at which an accurate prediction of the effects of acute or chronic oil inputs can be made. In order to more clearly define the po… more

Cesium--tungsten cathode for surface production of D/sup -/

Description: In the next generation of neutral beam systems for fusion, beam energy and efficiency requirements will go up, and high current D/sup -/ sources will be needed. The purpose of this note is to examine the problem of maintaining the cathode near its optimun state for the case of the supersonic jet conversion system. (MOW)

Summary report: an exploratory study of cost targets for solar electric power plants

Description: A preliminary evaluation was made of the economic goals that need to be achieved in the solar-electric R and D and demonstration programs so that solar can become a viable component of our national electric energy production system. Solar electric technologies considered are: solar thermal conversion, solar photovoltaic, wind energy conversion, and ocean thermal. Target costs were developed for selected applications of solar by comparison with known means of accomplishing the same end results. … more

Investigations of the inductively coupled plasma source for analyzing NURE water samples at the Los Alamos Scientific Laboratory

Description: A 3.4-meter direct-reading spectrograph is being used with an inductively coupled plasma source for the simultaneous determination of Ag, Bi, Cd, Cu, Nb, Ni, Pb, Sn, and W in water samples. We have attached a small digital computer to the system in order to obtain intensity data on each element once a second. After the intensities during a run on a sample have stabilized, the computer records the intensity data and outputs the average concentration for each element. To approach the published de… more

Experimental investigation of retrofit options for mobile homes

Description: A mobile home located (outdoors) in Oak Ridge, Tennessee, was tested to determine its energy-use characteristics for both space heating and cooling. The main objective was to determine the energy savings that can be achieved by the addition of retrofit items such as storm windows, skirting, and extra insulation and how these savings vary with weather conditions. Analyses of space heating data show that energy savings approaching 50 percent can be achieved, but analyses of space cooling data wer… more

Nucleation and dynamics of vortices in type-II superconductors

Description: The one- and two-dimensional Ginzburg-Landau equations are numerically integrated in a slab geometry, which is appropriate for comparison to experimental work done on films. When two-dimensional variations become energetically favorable, a vortex is found to nucleate and move to the center of the film with the Gibbs free energy decreasing during the process. An important process by which the energy is lowered during this nucleation procedure is found to be the savings in condensation energy ari… more
