Series of twenty-six photographs of components at the Aerojet-General Corporation, including entire constructions taken out-of-doors, assembly segments, and individual components. Many of the images are close-ups of specific pieces to show detail; few of the images are labeled, although some have captions or visible tags with part numbers.

This conference covers various aspects of fossil-fuel power plants based on coal or coal-conversion products, as well as the process control equipment involved in the conversion or combustion processes.

From abstract "As part of the Department of Energy (DoE) National Uranium Resource Evaluation Program, LKB Resources, Inc. has performed a rotary-wing reconnaissance high sensitivity radiometric and magnetic survey, encompassing several 1:250,000 quadrangles in southwestern Arizona and southeastern California. The surveyed area consisted of approximately 9300 line miles. The radiometric data was corrected and normalized to 400 feet terrain clearance. The data was identified as to rock type by correlating the data samples with existing geologic maps. Statistics defining the mean and standard deviation of each rock type are presented as listings in Volume I of this report. The departure of the data from its corresponding mean rock type is computed in terms of standard deviation units and is presented graphically as anomaly maps in Volume II and as computer listings in microfiche form in Volume I."

From introduction: The primary objective of this study was to determine the net transport of zinc into the study area from urbanized perimeter, out of the study area across the northern boundary of the study area, and across the sediment-water interface within the study area, all within a limited time period. A secondary objective was to assemble as much data on other trace metals--their concentrations and chemical states in water, suspended solids, sediments and interstitial fluids--as possible within the time and funding constraints of the study in order to describe the existing trace metal conditions in the south bay. Thus the bulk of effort was directed toward evaluating the distribution and movements of zinc, but the data collected on the distribution and movements of zinc, but the data collected on the distribution of other metals is important and is reported here.

From Abstract: "The micaceous schist ores yielded concentrates containing 95 to 98 percent mica, with recoveries ranging from 70 to 83 percent. Part 1 of this report summarizes the process development work and demonstrates the feasibility of producing commercial-grade mica concentrates. The report also includes details of commercial beneficiation and grinding of mica. Also included in part 2 of this report are details of commercial mica production, including methods of mining, recovering, and grinding mica, and information on the production, uses, and prices of mica."

Annual report discussing the activities and operation of the Senator Clair Engle Plant (CEP), a multi-effect multi-stage flash (MEMS) distillation plant for converting sea water, located in San Diego, California.

Report documenting the operation and economic considerations of the multi-stage flash distillation plant in San Diego, California.

From Introduction: "The Office of Saline Water (OSW) maintains the MSF Module at the San Diego Test Facility, Chula Vista, California, for the purpose of further advancing and developing the state of art of the multistage flash distillation process and thereby reduce the cost of seawater conversion. The MSF Module has been built and operated to obtain engineering design and operating data to serve as a basis for: a. Future process development. b. Improved full scale plant design. Improved full scale plant operating conditions."

From Summary, Conclusions, and Recommendations: "The operation and development programs carried out in the CEP, E-1A and LMC plant during the period July 1, 1970 to December 31, 1970 are described in this report. Data was developed on several development tasks as follows. A summary is presented of material evaluation studies made over the past three and a half years. Data on the experiences with coatings, mortar linings, elastomers, and nonferrous and ferrous metals are included. Details are presented of coatings and linings installed in the CEP II Effect including methods of surface preparation and costs."

From Introduction: "This report covers the activities by Catalytic, Inc., during the contract period from June 1, 1969 to June 30, 1970, a thirteen month period."

From summary: Granitic and contact-metamorphic rocks of the Owens Valley area were sampled to determine their favorability for uranium. Uranium deposits associated with these rocks were examined to determine the mode of occurrence.

Supplementary data containing geologic, location, and radiometric maps of Owens Valley area, Inyo and Mono Counties, California, and Esmeralda and Mineral Counties, Nevada.

Partial abstract: "This study was conducted to determine the effect that the proposed Marysville Lake pump-storage hydropower (2250-mw power plant) project would have on downstream water temperatures. A one-dimensional numerical model was used for simulation and prediction of temperatures within and downstream of Marysville Lake. Two physical hydraulic models were used for study and description of the hydrodynamic response of the project. Information from the physical models was necessary to determine coefficients used by algorithms within the mathematical model."

Report and geographical survey. This report examines the distribution of nitrates in the Redland area's ground water and concludes that this distribution depends primarily upon depth below the water table and areal location. Includes several maps and figures.

Abstract: The Mojave Water Agency includes several desert basins where ground water in storage is many times as great as the average annual recharge. The Johnson Valley area was evaluated to find (1) the quantity of ground water in storage, (2) the chemical quality of the ground water, and (3) the potential for storage of recharge water in the unsaturated zone. Johnson Valley contains about 250,000 acre-feet of water in storage, of which about half can be considered recoverable. About 250,000 acre-feet of void space in the unsaturated alluvium is available for storage of imported water, but considerably less than this amount of recharged water could be recovered. The quality of the water in storage is satisfactory for public consumption, although water from some areas has high fluoride concentrations and should be mixed with water of low fluoride concentration.
