Petrology of tuff units from the J-13 drill site, Jackass Flats, Nevada

Description: The J-13 drill hole, located in Jackass Flats, Nevada Test Site, has penetrated 125 m of alluvium and 932 m of tuff. Most of the tuff deposits consist of welded tuffs; glass phases in the tuffs have been replaced by authigenic minerals, mainly K-feldspar, silica, and zeolites. The zonation of authigenic minerals, with depth, indictes that alteration of glass phases and filling of vugs occurred during welding and compaction of tuff units soon after deposition and by interaction with groundwater.… more

Projection of Favorable Gas-Producting Areas From Paleoenvironmental Data

Description: Paleoenvironmental biofacies analysis of recent wells in dark Devonian shales in the Applachian Basin has shown that these facies can be projected to areas with no control points. In particular, the facies distribution in Perry County, Kentucky, were found to be precisely those that were predicted earlier from biofacies and organic geochemical data from the VA-1 well in Wise County, Virginia, and the KY-2 well in Martin County, Kentucky. This demonstrates the importance of these data in assessi… more

Growth of molten core debris pools in concrete. Part II. A. Pool growth in composite beds; B. Effect of overlaying steel layers. Final report, March 1, 1978-September 30, 1979. [LMFBR]

Description: The heat and mass transfer processes taking place in molten core debris/concrete systems have been experimentally investigated. Two types of experiments have been conducted. The first experiment simulates the growth of a molten debris pool in a composite sacrificial bed. This experiment models debris pool growth in an inner, low-melting point, sacrificial material zone followed by a melting attack on the concrete bed. The purpose of the inner zone is to quickly melt and dilute the debris pool s… more

Use of a General Nonlinear Least-Squares Curve Fitting Program With Nonclosed Form Relationships. [GNLS, in FORTRAN for CDC Computers]

Description: A use for GNLS, a general nonlinear least-squares curve fitting program, is presented. In this use GNLS determines a set of best parameters for relationships that cannot be written in closed form. This program can be useful for experimenters who need to determine experimental parameters by fitting nonclosed-form relationships to experimental data. Two examples are given to indicate how GNLS can be used for this type of problem. 11 figures.

Analysis of thermal efficiency for hydrogasification and gasification/methanation

Description: To confirm the potentially greater thermodynamic efficiency of hydrogasification, a study was made of carbon conversion and resulting thermal efficiency of methane production via hydrogasification as compared to gasification/methanation. The alternative systems were first compared on an ideal process basis. This approach neglects limitations imposed by the thermodynamics and kinetics of the various chemical reactions and indicates maximum potential conversion of coal to methane. These results w… more

Segregation effects in JBK-75

Description: Chemical segregation of alloying elements, can be a severe problem in complex alloys. Many problems have been experienced with developing fabrication processes for JBK-75 and it is suggested that these difficulties may be related in part to the degree of chemical heterogeneity that exists in the alloy. Early testing and qualification of the alloy was made on relatively homogeneous samples, which came from small diameter ingots. In large size ingots used for production, it is more difficult to a… more

Emerging materials for solar cell applications: electrodeposited CdTe. Third quarter report, September 1-November 30, 1979

Description: Major emphasis during the period was centered on improving the material properties of electrodeposited CdTe. Using newly devised means for peeling thin CdTe films off the ITO-coated glass substrates, it was possible to accurately measure material density and electrical resistivity. Density proved to be 40% below the bulk CdTe figure of about 6 gm/cm/sup 3/, while resistivity of supposedly doped CdTe films exceeded 10/sup 5/..cap omega.. - cm. These findings prompted initiation of a beneficial c… more

Slurry spray distribution within a simulated laboratory scale spray dryer

Description: It was found that the distribution of liquid striking the sides of a simulated room temperature spray dryer was not significantly altered by the choice of nozles, nor by a variation in nozzle operating conditions. Instead, it was found to be a function of the spray dryer's configuration. A cocurrent flow of air down the drying cylinder, not possible with PNL's closed top, favorably altered the spray distribution by both decreasing the amount of liquid striking the interior of the cylinder from … more
