Production of oil from Intermountain West tar sands deposits
Six tar sand deposits in the Intermountain West, each containing more than one billion barrels of oil in place, are identified. All of these deposits are in eastern Utah and contain a total of twenty-eight billion barrels of oil. The names of the six deposits arranged in descending order of desirability for large-scale surface-mining oil recovery operations are as follows: Sunnyside, Tar Sand Triangle, Asphalt Ridge, P.R. Spring, Circle Cliffs, and Hill Creek. An overview of each deposit is presented including geology, surface-mining variables, chemical processing variables, environmental aspects, and economics. A comparison of Utah tar sands and Athabasca, Alberta, Canada tar sands is also presented.

Environmental surveillance at Hanford for CY-1975
Environmental data collected during 1975 showed continued compliance of Hanford operations with all state and federal regulations. Levels of radioactivity in the atmosphere at all offsite sampling locations were indistinguishable from levels due to natural causes and worldwide fallout. Radiological, chemical, biological, and physical analyses of Columbia River water of the Hanford Reservation did not show any identifiable effect due to Hanford operations with the exception of temperature. The majority of radioactivity measured in foods was the result of naturally occurring /sup 40/K and the fallout radionuclides /sup 90/Sr and /sup 137/Cs. External radiation levels in the Hanford environs were measured by thermoluminescent dosimeters deployed at 17 different locations, TLDs immersed in the Columbia River at four locations, and several portable instrument surveys. The total background dose was estimated to be approximately 100 m rem/yr. Radioactivity in wildlife, oysters, sediment in the Columbia River, and on the islands from past once-through cooling production reactor operations was also evaluated. The total body dose to the population received during 1975 and the 50-yr dose commitment received from effluents released during 1975 were estimated to be 0.93 and 1.5 man-rem, respectively. (HLW)

Radioecology of Natural Systems in Colordao. Fourteenth Annual Progress Report, May 1, 1975--July 31, 1976. [Pu Diffusion in Terrestrial Ecosystems at Rocky Flats Plant]
This report summarizes project activities during the period May 1, 1975 through July 31, 1976. The major study on the distribution and levels of Pu in major components of the terrestrial ecosystem at Rocky Flats was completed. Supportive studies on the ecology and pathology of small mammals and their role in Pu transport were essentially completed as well. Detailed studies on mule deer food habits, population dynamics, and movements at Rocky Flats are progressing. These studies are designed to measure the potential of mule deer in transporting Pu to uncontrolled areas. Alpha autoradiographic studies designed to measure Pu particle size and distribution and spatial patterns in soil were initiated. Field and greenhouse transport pathways from soil to vegetation are in progress and some early results reported. The status of studies on seasonal kinetics of Cs in a montane lake and stable lead geochemistry in an alpine lake watershed are also reported.

Ecological aspects of decommissioning and decontamination of facilities on the Hanford Reservation
The Hanford environment and biota are described in relation to decommissioning of obsolescent facilities contaminated with low-levels of radioactive materials. The aridity at Hanford limits both the productivity and diversity of biota. Both productivity and diversity are increased when water is added, as for example on the margins of ponds. Certain plants, especially Salsola kali (Russian thistle or tumbleweed), are avid accumulators of minerals and will accumulate radioactive materials if their roots come into contact with contaminated soils. Data on concentration ratios (pCi per gDW of plant/pCi per gDW soil) are given for several native plants for long-lived radionuclides. Plants are generally more resistant than animals to ionizing radiation so that impacts of high-level radiation sources would be expected to occur primarily in the animals. Mammals and birds are discussed along with information on where they are to be found on the Reservation and what role they may play in the long-term management of radioactive wastes. Food habits of animals are discussed and plants which are palatable to common herbivores are listed. Food chains leading to man are shown to be very limited, including a soil-plant-mule deer-man path for terrestrial sites and a pond-waterfowl-man pathway for pond sites. Retention basins …

Study of geothermal prospects in the western United States
The commercial development potential of 13 underdeveloped geothermal prospects in the Western United States has been examined and the prospects have been ranked in order of relative potential for development on the basis of investment considerations. The following were considered in the ranking: geotechnical and engineering data, energy market accessibility, administrative constraints, and environmental and socio-economic factors. The primary ranking criterion is the unit cost of energy production expected from each prospect. This criterion is obtained principally from expected reservoir temperatures and depths. Secondary criteria are administrative constraints, environmental factors and the quality of the geotechnical data. The Roosevelt, Utah, prospect ranks first in development potential followed in order by Beowawe, Nevada; Coso Hot Springs, California; Long Valley, California; and Brady's Hot Springs, Nevada.

LASL Hot Dry Rock Geothermal Project. Progress report, July 1, 1975--June 30, 1976
Successful drilling into hard crystalline rock was accomplished to depths of about 3 km. Hydraulic fractures in the crystalline rock with radii as large as 150 m were produced. Values of in situ permeability of the Fenton Hill granite were measured. Directional drilling at depths of up to 3 km was accomplished. At least 90 to 95 percent of water injected into fractured regions was recovered. A connection was established between two deep boreholes through a fractured region of hot granite for the first time. Instruments were developed to operate for several hours under the downhole conditions. The compressional and shear components of seismic signals produced by fracture extension and inflation were detected downholes. Acoustic ranging has generally identified the relative positions of two boreholes at several depths. Self-potential and induced potential techniques have determined vertical fracture lengths at the borehole. Pressure-flow and fluid residence time distribution studies have measured properties of the downhole system. Core sample studies have provided physical and chemical data. Techniques were developed to examine reservoir performance. A geothermal power-production model was formulated. (MHR)

Selection of heat disposal methods for a Hanford Nuclear Energy Center
Selection of the best method for disposal of the waste heat from a large power generation center requires a comprehensive comparison of the costs and environmental effects. The objective is to identify the heat dissipation method with the minimum total economic and environmental cost. A 20 reactor HNEC will dissipate about 50,000 MWt of waste heat; a 40 reactor HNEC would release about 100,000 MWt. This is a much larger discharge of heat than has occurred from other concentrated industrial facilities and consequently a special analysis is required to determine the permissibility of such a large heat disposal and the best methods of disposal. It is possible that some methods of disposal will not be permissible because of excessive environmental effects or that the optimum disposal method may include a combination of several methods. A preliminary analysis is presented of the Hanford Nuclear Energy Center heat disposal problem to determine the best methods for disposal and any obvious limitations on the amount of heat that can be released. The analysis is based, in part, on information from an interim conceptual study, a heat sink management analysis, and a meteorological analysis.
