Geothermal Resource Investigations: Imperial Valley, California. Site location report, deep geothermal test well

Description: Data for use in siting a deep geothermal test well in the East Mesa area of Imperial County, California are summarized. The data relate to a geothermal anomaly known as the Mesa anomaly. It is concluded that the thermal feature forming the Mesa anomaly is a manifestation of a sizable convective hydrothermal system embracing an area of about 19 square miles and a considerable volume of saturated sediment in the Salton trough. The upper surface of the thermal feature between depths of 200 and 1,0… more

Dissipation of the reactor heat at the Savannah River Plant

Description: The effluent cooling water from the heat exchangers of the Savannah River nuclear reactors is cooled by natural processes as it flows through the stream beds, canals, ponds, and swamps on the plant site. The Langhaar equation, which gives the rate of heat removal from the water surface as a function of the surface temperature, air temperature, relative humidity, and wind speed, is applied satisfactorily to calculate the cooling that occurs at all temperature levels and for all modes of water fl… more

An Evaluation of the Use of a Quantitative Image Analyzer to Determine Microhardness Values

Description: The use of quantitative image analyzer to determine microhardness values was investigated. Microhardness traverses were made across chemically polished, partially oxidized T-111 alloy specimens using both Vickers and Knoop indenters. Microhardness values were obtained from both area and diagonal readings using a Classimat image analyzer (Classimat is a registered trademark of E. Leitz, Inc., Rockliegh, N. J.). These values were then compared with those obtained by conventional optical measureme… more

A Technique for the Metallographic Preparation of Lead

Description: A technique is described which enables lead to be metallographically prepared to reveal the true microstructure with good edge retention. The technique consists of a series of mechanical grinding and polishing steps each of which is followed by a chemical polish. The depth of the deformed metal layer, due to grinding, was measured as well as the rate of metal removed by the chemical polish. The technique can be used to achieve relatively good results in a short period of time.

Reaction Diffusion in the Silver-Zinc and Silver-Aluminum Systems

Description: Multiphase diffusion was investigated in the silver-zinc and silver-aluminum binary systems using metallographic and electron microprobe techniques. Diffusion couples in the silver-zinc system were prepared by electroplating silver onto coupons of a AgZn alloy (62.2% Ag), and diffusion behavior was studied at 600 and 650 degrees C. Couples in the silver-aluminum system were prepared by electroplating silver onto coupons of a AgAl alloy (87.7% Ag) and diffusion measurements were made between 400… more

Douglas United Nuclear monthly report, October 1971

Description: N Reactor operated during 22 days of the month with a time operated efficiency of 69.5 percent and electrical production of 427.54 x 10{sup 6} kwh. New daily and weekly generation records were established. A small seismic shock was felt at N Reactor on October 25. No effects on plant operation or facilities were observed.
