Numerical simulation of material transport in a regional ground-water flow system

Description: A numerical model of a regional ground-water flow system (not site specific) was coupled with a material transport model in order to study the influence of porosity and distribution coefficients in bedded media. The effects on model performance were discerned from long-term material transport simulations. Model performance was based on initial breakthrough time, average breakthrough time, and the standard deviation of the breakthrough curve at a discharge surface. Large differences in model per… more

Measurements of insolation variation over a solar collector field

Description: The experiment described in this report makes observations to determine the direct insolation every 16 sec at corners of a quadrilateral approximately 600 meters in size located near Barstow, California. This size approximates the collector field of the solar power plant to be built near Barstow. Data from the first three months of operation of this experiment indicate cloudy conditions, capable of affecting the operation of a solar power plant, occurred during 15% of the daylight hours of some… more

Lawrence Livermore Laboratory heavy ion fusion program

Description: In the large fusion program at Livermore we are actively doing research in most areas of inertial confinement fusion. The areas in which we are funded for research specific to heavy ion fusion are: (1) target design; (2) energy conversion chamber design and (3) ion beam propagation in the combustion chamber. There are two main thrusts to the target design effort: (1) development of targets which are optimally suited to heavy ion fusion power production and (2) fundamental studies of the beam-ta… more

Rio Blanco massive hydraulic fracture well RB-MHF-3. Final report

Description: The Rio Blanco Massive Hydraulic Fracturing Project was fielded in 1974 as a joint Industry/ERDA demonstration to test the relative effectiveness of MHF in the same formations that were stimulated by the Rio Blanco nuclear fracturing experiment. The project is essentially a companion effort to and a continuation of the preceding nuclear stimulation project, which took place in May, 1973. The well was fractured a total of four times, twice in the Upper Mesaverde and twice in the Fort Union. A fi… more

Hydrogen attack of steel. Progress report, April 1, 1978--March 31, 1979

Description: Four normalized carbon steels made in different ways (Si-killed, Al-killed, REM-treated, and electroslag refined) were studied to determine the role of differing fine inclusions on the early stages of hydrogen attack (HA). Hydrogen exposures were made at 450/sup 0/C (6.5 MPa) and 375/sup 0/C (7.6 MPa). The first stage of HA is shown to be the development of a closely spaced (1-2 ..mu..m) array of small bubbles over the ferrite/pearlite, or occasionally the ferrite/ferrite boundaries. These grew… more

A scheme to improve the low energy luminosity in LEP

Description: In the design of large electron positron colliding beam facilities, it has become customary to use a certain optimization procedure to establish desired beam performance. The results of this procedure are the minimum requirements in terms of RF-power, bending radius and focusing to achieve a desired luminosity at a given energy. This procedure, however, neglects the optimization of the storage ring performance below and above that design energy. Below the design energy the luminosity is optimiz… more
