Testing geopressured geothermal reservoirs in existing wells. Saldana well No. 2, Zapata County, Texas. Volume I. Completion and testing. Final report
The Saldana Well No. 2, approximately 35 miles Southeast of the city of Laredo, Texas, was the sixth successful test of a geopressured-geothermal aquifer under the DOE Wells of Opportunity Program. The well was tested through the annulus between 7-inch casing and 2-3/8 inch tubing. The interval tested was from 9745 to 9820 feet. The geological section was the 1st Hinnant Sand, an upper member of the Wilcox Group. Produced water was injected into the Saldana Well No. 1, which was also acquired from Riddle Oil Company and converted to a disposal well. A Miocene salt water sand was perforated from 3005 to 3100 feet for disposal. One pressure drawdown flow test and one pressure buildup test were conducted during a 10-day period. A total of 9328 barrels of water was produced. The highest sustained flow rate was 1950 BWPD.

Computer modeling of piezoresistive gauges
A computer model of a piezoresistive gauge subject to shock loading is developed. The time-dependent two-dimensional response of the gauge is calculated. The stress and strain components of the gauge are determined assuming elastic-plastic material properties. The model is compared with experiment for four cases. An ytterbium foil gauge in a PPMA medum subjected to a 0.5 Gp plane shock wave, where the gauge is presented to the shock with its flat surface both parallel and perpendicular to the front. A similar comparison is made for a manganin foil subjected to a 2.7 Gp shock. The signals are compared also with a calibration equation derived with the gauge and medium properties accounted for but with the assumption that the gauge is in stress equilibrium with the shocked medium.

Study of the formation and effects of sigma phase in 21-6-9 stainless steel
Work performed to date on the study of the formation and effects of sigma phase in 21-6-9 stainless steel is summarized in this report. Sigma phase was identified in forgings and as-rolled plate by color etching and microprobe analysis. In as-rolled plate sigma was found to start transforming from delta ferrite within 30 minutes at 1500/sup 0/F, with almost complete transformation after 24 hours at 1500/sup 0/F. The effect of sigma phase on room temperature mechanical properties was evaluated by tensile testing, Charpy impact testing, and impact shear testing. Sigma phase was found to severely reduce transverse ductility and longtudinal and transverse impact resistance. The greater the amount of sigma present, the greater was its effect on mechanical properties. Vendor contacts indicated that controlling delta ferrite to a minimum in the as-rolled plate is both possible and practical.

Responses to the low-level-radiation controversy
Some data sets dealing with the hazards of low-level radiation are discussed. It is concluded that none of these reports, individually or collectively, changes appreciably or even significantly the evaluations of possible low-level radiation effects that have been made by several authoritative national and international groups.

Fusion-neutron damage in superconductors and magnet stabilizers
Two NbTi and two Cu wires were irradiated with 14.8 MeV neutrons at 4.2 K to fluences of 6 to 8 x 10/sup 20/ n/m/sup 2/, using RTNS-II. Electrical resistances of Cu were monitored during irradiation. Magnetoresistances were measured in fields up to 12.4 T before and after irradiation and after isochronal annealing up to 273 K. Critical currents of NbTi were measured after irradiation, in feilds up to 10 T. The initial rate of increase of resistivity of the Cu was found to be 2.23 x 10/sup -31/ (..cap omega..-m)/(n/m/sup 2/). This rate could be predicted from fission reactor irradiations using damage energy scaling. The maximum observed change in the NbTi critical was a decrease of 3% at 4 T. At 6, 8, and 10 T there were no significant changes.

Tritium inventory of a target factor in an ICF power plant
A preliminary parametric study has been performed to estimate the tritium inventory of a conjectured Target Factory. The inventory of a proposed tritiated fuel processing system was determined as a function of production efficiency, storage factor, and time interval for the slowest processing step. Results indicated that a study of this type will be beneficial in evaluating possible processing schemes for the production of tritiated laser fusion targets.

Uranium-series dating of pedogenic carbonates from the Livermore Valley, California
A uranium-series dating technique has been applied to pedogenic carbonates from the Livermore Valley in California. The results from geomorphologically distinct Quaternary alluvial units are internally consistent and for one alluvial unit are corroborated by a concordant /sup 14/C age for an associated wood fragment. In appropriate situations, age dates for pedogenic carbonates derived using this technique may provide a time stratigraphy for alluvial units and hence provide some limits (minimum age) for last fault movement.
