Effect of strain-gage surface preparation techniques on beryllium

Description: Beryllium is a metal sensitive to machining damage, causing a loss in mechanical properties. Since some mechanical abrading is often used in surface preparation for mounting strain gages, it is desirable to know whether the abrading produces flaws. Metallographic study of beryllium subjected to four different surface preparation methods was carried out. It was determined that the gentle abrading necessary for affixing strain gages produced a negligible density and depth of flaws and did not low… more

Fuel Gas Demonstration Plant Program: Small-Scale Industrial Project. Final report, Phase I

Description: During the Erie internal alternate fuel review in 1976, the ERDA RFP for small scale demonstration plants was released and Erie responded. The basis of the contract proposal included design, construction and operation of a Demonstration Plant, which could be expanded to a full-sized industrial plant. The government specifically required the ability to handle Eastern, high-caking, high-sulfur coal. Erie's proposal was to utilize low-caking, low-sulfur coals with the Eastern coals optional. Phase… more

Determination of the pipe stemming load

Description: A mechanical model for the emplacement pipe system is developed. The model is then employed to determine the force applied to the surface collar of the emplacement pipe, the pipe-stemming load, and the stress along the emplacement pipe as a function of stemming height. These results are presented as integrals and a method for their numerical integration is given.

Carbonate scaling - literature review and analysis

Description: A survey of the literature on carbonate scaling is presented as it affects geothermal fluid systems. The geothermal brine, as the fluid is called, contains a number of chemical constituents which have leached into it from the reservoir rock. As the hot fluid is withdrawn through wells, a flow of steam, water, or a mixture of steam and water, results. If the well flows at a high enough rate, some brine will flash to steam because of the pressure drop, resulting in the steam/water flow mixture. T… more

Electron cyclotron resonance heating of tandem mirrors

Description: Heating electrons by microwave power near either the electron cyclotron frequency or its harmonic is analyzed in some detail. The purpose of this study is to determine whether electrons in current or future mirror devices could be heated by electromagnetic waves in this frequency range. Absorption lengths, accessibility conditions, and appropriate polarization are among the concerns studied. It is found that the Tandem Mirror Experiment (TMX) may efficiently be heated by the extraordinary mode … more

Single-charge craters excavated during subsurface high-explosive experiments at Big Black Test Site, Mississippi

Description: Single-charge and row-charge subsurface cratering experiments were performed to learn how close-spacing enhances single-crater dimensions. Our first experimental phase established cratering curves for 60-lb charges of the chemical explosive. For the second phase, to be described in a subsequent report, the Row-cratering experiments were designed and executed. This data report contains excavated dimensions and auxiliary data for the single-charge cratering experiments. The dimensions for the row… more
