Thermal depletion of a geothermal reservoir with both fracture and pore permeability

Description: A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use… more

Geothermal direct-contact heat exchange. Final report

Description: A glass direct contact heat exchange column was operated in the laboratory at atmospheric pressure using hot water and normal hexane. Column internals tested included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1{sup 0}C for packing to 13{sup 0}C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the … more

Effects of the trip phenomenon on the toughness of heat treatable alloy steels. [AISI 4330]

Description: It is shown that substantial amounts of untransformed austenite may be obtained in low alloy steels by a combination of alloy modification (addition of silicon) and heat treatment. In silicon modified AISI 4330 steel, the amount of untransformed austenite is varied by utilizing isothermal treatments both above and below the M/sub s/. The stability of the untransformed austenite is found to be dependent on the amount of silicon and also on the tempering temperature. A magnetic saturation techniq… more

Numeric processor and text manipulator for the ''MASTER CONTROL'' data-base-management system

Description: The numeric and text processor of the MASTER CONTROL (MCP) data-base-management system permits the user to define fields and arrays that are functionally dependent on the data retained in a data base. This allows the storage of only the essential and unique information and data, and the calculation of derivable quantities as required. The derived quantity can be expressed as an arithmetic expression, that is, a functional relationship. Functions can be multiply subscripted and can be embedded w… more

Feasibility of a MHD generator as a transmitter for electromagnetic sounding of the earth. [Mathematical models]

Description: Development of a high-intensity source for use in time-domain electromagnetic (TDEM) soundings would permit investigation of geothermal systems to much greater depth than is now possible with controlled-source methods. The development of such a source is critically dependent upon a powerful, mobile generator. Magnetohydrodynamic pulse generators satisfy the weight and power requirements for such a generator. However, existing MHD generators which are used in geophysical applications are solid f… more

Preliminary study of the recycling of spent gases from the iodine laser

Description: A process is proposed for recycling the spent gases from the iodine laser. Using a simplified form of this process, a preliminary estimate of the energy cost to recycle the perfluoroisopropyliodide-argon gas mixture used as the laser medium in the iodine laser was made. If r is defined as the ratio of the recycling energy to the output energy of the laser, a figure of 70 is arrived at for the most optimistic conditions and 160 for the most probable conditions. A major portion of the energy nece… more

Investigation into the dissolution and direct assay of high-fired plutonium dioxide. [Fusion-melt with potassium pyrosulfate and sodium peroxide]

Description: A fusion-melt and dissolution assay method has been developed and tested for the quantitative analysis of high-fired plutonium dioxide. The method employs fusion of the plutonium dioxide at temperatures greater than the melting point of an eutectic mixture of potassium pyrosulfate plus sodium peroxide. The resultant melt is then titrated directly by either controlled potential coulometry or a gravimetric titration, using standardized ceric sulfate as the titrant. It has been concluded from thes… more

Applicability of chemical getter beds to scavenge tritium from inert gases

Description: Chemical getters can be used to scavenge tritium from inert gases. Cerium, which forms a hydride with a low dissociation pressure, has high reactivity, and is relatively inexpensive, is a good candidate getter material for such a scavenger system. Mathematical models for using cerium in both fixed- and fluidized-bed reactors predict satisfactory performance. Moreover, the capital cost of a gettering system, estimated to be between $115,000 and $166,000 (m/sup 3//s) flow, is competitive with tha… more
