Analysis of alternative-fuel price trajectories
Findings are presented from a study to (1) acquire, analyze, and report alternative published price projections including both oil- and coal-price trajectories, and to (2) apply the fixed-annuity formula to the updated primary source projections (Energy Information Administration; Data Resources, Inc.; and Wharton Econometric Forecasting Associates, Inc.) and to the newly acquired price projections. This report also encompasses: comparisons of key assumptions underlying the price projections, and a discussion of the applicability of the fixed-annuity formula as used in the alternative-cost calculation. Section II contains graphic presentations of all updated and newly acquired coal and oil price forecasts and the corresponding calculated annuity equivalents, tabulated presentations and discussions of each forecast and underlying assumptions, and a description of how each forecast price series was transformed into input for the present-value formulas.

District Heating System, City of Caliente, Nevada.
Considerable preliminary information has been gathered on the heating requirements of Caliente. It is reported that the City consists of 320 residential buildings, 90 commercial buildings, and two industries, a total of 412. Heating is predominantly by fuel oil or LPG. Only 113 of the residential, 17 of the commercial, and 1 of the industrial buildings are heated electrically. It is also reported that the average electrically heated home consumed 13,600 KWH in the year 1978, and the average all-electric commercial building 53,100 KWH. A geothermal district heating system for the city of Caliente, Nevada is economically feasible. This assumes that a 160/sup 0/F geothermal source capable of delivering a peak load of 850 gallons per minute from a relatively shallow depth can be located within, or near, the City boundaries. Total volume needed from the geothermal reservoir during the 20 year project life is 5400 acre-feet. Based on 8% bond financing of a capital investment for equipment of $2,500,000, a present worth of about $5,400,000 is generated over the project life. Total energy saved during the project life is 63 million KWH of electricity, and 7.5 millions therms of fuel.

Economic Comparison of Heating Facilities: 75 Unit Apartment, Stewart-Lennox Area, Klamath Falls, Oregon.
The apartment building would consist of about 75 units of about 900 square feet each. Also included would be an outdoor swimming pool and an enclosed activity wing of about 11,000 square feet. Though no deep geothermal wells have been drilled in the immediate area, opinions were obtained that 150/sup 0/F water would be present at 2500 feet and 80/sup 0/F water at about 1000 feet. Based on this information the comparative economics of using geothermal as a heat source versus conventional electrical heating was developed. The purpose of this comparison is to determine if there is economic incentive for the expenditure necessary to define and prove the extent of the geothermal resource. Four systems were compared, each would provide space heating, supply domestic hot water, and heat the swimming pool. A brief description of each of the systems is given. (MHR)

Evaluation of the DYMAC demonstration program. Phase III report. [LASL Plutonium Processing Facility]
An accountancy system based on the Dynamic Materials Accountability (DYMAC) System has been in operation at the Plutonium Processing Facility at the Los Alamos National Laboratory since January 1978. This system, now designated the Plutonium Facility/Los Alamos Safeguards System (PF/LASS), has enhanced nuclear material accountability and process control at the Los Alamos facility. The nondestructive assay instruments and the central computer system are operating accurately and reliably. As anticipated, several uses of the system, notably scrap control and quality control, have developed in addition to safeguards. The successes of this experiment strongly suggest that implementation of DYMAC-based systems should be attempted at other facilities.

Feasibility of Recycling Thorium in a Fusion-Fission Hybrid/PWR Symbiotic System
A study was made of the economic impact of high levels of radioactivity in the thorium fuel cycle. The sources of this radioactivity and means of calculating the radioactive levels at various stages in the fuel cycle are discussed and estimates of expected levels are given. The feasibility of various methods of recycling thorium is discussed. These methods include direct recycle, recycle after storage for 14 years to allow radioactivity to decrease, shortening irradiation times to limit radioactivity build up, and the use of the window in time immediately after reprocessing where radioactivity levels are diminished. An economic comparison is made for the first two methods together with the throwaway option where thorium is not recycled using a mass energy flow model developed for a CTHR (Commercial Tokamak Hybrid Reactor), a fusion-fission hybrid reactor which serves as fuel producer for several PWR reactors.

GeoEnergy technology
The goal of the GeoEnergy Technology Program is to improve the understanding and efficiency of energy extraction and conversion from geologic resources, hence maintaining domestic production capability of fossil energy resources and expanding the usage of geothermal energy. The GeoEnergy Technology Program conducts projects for the Department of Energy in four resource areas--coal, oil and gas, synthetic fuels and geothermal energy. These projects, which are conducted collaboratively with private industry and DOE`s Energy Technology Centers, draw heavily on expertise derived from the nuclear weapons engineering capabilities of Sandia. The primary technologies utilized in the program are instrumentation development and application, geotechnical engineering, drilling and well completions, and chemical and physical process research. Studies in all four resource areas are described.

Geothermal home heating facilities, Green Valley Estates, Fernley, Nevada
A housing development to be located at Fernley, Nevada, about thirty miles east of Reno, is in an area of known geothermal water. The practicality of heating these homes with this water, as an alternative to heating with natural gas, has been investigated. A preliminary engineering design of a geothermal system was developed. This design permitted capital and operating cost to be estimated and a financial evaluation to be made. Two cases were investigated. The Base Case provides facilities for heating a tract of 371 houses. The Alternate Case adds another tract of 371 for a total of 742 houses. Geothermal water is to be provided by two wells and the used water reinjected into a third well. The Base Case has a rate of return on capital investment of 13.0 percent before taxes. The Alternate Case has a rate of return of 16.5 percent before taxes. The Alternate Case has a more favorable return due primarily to the assumption that each well has the capacity to produce 800 gpm of geothermal water. This is enough to provide for the additional 371 houses in the Alternate Case without an additional well. (MHR)

Heating facilities for the city schools, Ephrata, Washington
The City of Ephrata, Washington has an existing well that has the capability of pumping 2200 gallons per minute of 86/sup 0/F water into the City drinking water system. To determine the economic practicality of using the City water to heat the schools, one school (Middle School) was selected for evaluation. Two cases were considered. Case 1 uses a two stage water-to-water heat pump to produce a 190/sup 0/F circulating hot water steam. This would be compatible with the existing system and essentially no retrofit costs for the room convective heating system would be incurred. Case 2 uses a single stage water-to-water heat pump to produce a 140/sup 0/F circulating hot water stream. Retrofit costs would incur for additional room convection equipment. In both cases the heat pump is sized to furnish the total heating and hot water requirements of the school. However, one of the existing boilers is left in place to serve as standby. The Middle School evaluation shows the single stage heat pump to be most cost effective, having a return on invested capital of about 19%. Projecting the single stage evaluation to include all the schools, the total conversion cost would be about $800,000. This includes …

Hydrogeochemical and stream sediment reconnaissance basic data for Dodge City NTMS Quadrangle, Kansas
Results of a reconnaissance geochemical survey of the Dodge City Quadrangle are reported. Field and laboratory data are presented for 756 groundwater and 321 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwater data indicate that the most promising areas for uranium mineralization are as follows: (1) in the north central area of the quadrangle within close proximity to the Arkansas River, mostly from waters of the Ogallala Formation; (2) in the west central area, from groundwater samples of the Dakota and the Ogallala Formations; and (3) between the North Fork of the Cimarron River and the main Cimarron River, mostly in waters from the Ogallala Formation. Associated with the high uranium values are high concentrations for magnesium, strontium, and sulfate. Of the groundwater samples taken 81% were collected from the Ogallala Formation. Stream sediment data indicate high uranium concentrations in scattered samples in the northwestern, central, and southwestern areas of the quadrangle. Most of the samples with high uranium values were collected from …

Methods of economic analysis applied to fusion research. Fourth annual report
The current study reported here has involved three separate tasks. The first task deals with the development of expected utility analysis techniques for economic evaluation of fusion research. A decision analytic model is developed for the incorporation of market uncertainties, as well as technological uncertainties in an economic evaluation of long-range energy research. The model is applied to the case of fusion research. The second task deals with the potential effects of long-range energy RD and D on fossil fuel prices. ECON's previous fossil fuel price model is extended to incorporate a dynamic demand function. The dynamic demand function supports price fluctuations such as those observed in the marketplace. The third task examines alternative uses of fusion technologies, specifically superconducting technologies and first wall materials to determine the potential for alternative, nonfusion use of these technologies. In both cases, numerous alternative uses are found.

Municipal geothermal heat utilization plan for Glenwood Springs, Colorado
A study has been made of the engineering and economic feasibility of utilizing the geothermal resource underlying Glenwood Springs Colorado, to heat a group of public buildings. The results have shown that the use of geothermal heat is indeed feasible when compared to the cost of natural gas. The proposed system is composed of a wellhead plate heat exchanger which feeds a closed distribution loop of treated water circulated to the buildings which form the load. The base case system was designed to supply twice the demand created by the seven public buildings in order to take advantage of some economies of scale. To increase the utilization factor of the available geothermal energy, a peaking boiler which burns natural gas is recommended. Disposal of the cooled brine would be via underground injection. Considerable study was done to examine the impact of reduced operating temperature on the existing heating systems. Several options to minimize this problem were identified. Economic analyses were completed to determine the present values of heat from the geothermal system and from the present natural gas over a 30 year projected system life. For the base case savings of over $1 million were shown. Sensitivities of the economics …

Particle beam fusion
Today, in keeping with Sandia Laboratories` designation by the Department of Energy as the lead laboratory for the pulsed power approach to fusion, its efforts include major research activities and the construction of new facilities at its Albuquerque site. Additionally, in its capacity as lead laboratory, Sandia coordinates DOE-supported pulsed power fusion work at other government operated laboratories, with industrial contractors, and universities. The beginning of Sandia`s involvement in developing fusion power was an outgrowth of its contributions to the nation`s nuclear weapon program. The Laboratories` work in the early 1960`s emphasized the use of pulsed radiation environments to test the resistance of US nuclear weapons to enemy nuclear bursts. A careful study of options for fusion power indicated that Sandia`s expertise in the pulsed power field could provide a powerful match to ignite fusion fuel. Although creating test environments is an achieved goal of Sandia`s overall program, this work and other military tasks protected by appropriate security regulations will continue, making full use of the same pulsed power technology and accelerators as the fusion-for-energy program. Major goals of Sandia`s fusion program including the following: (1) complete a particle accelerator to deliver sufficient beam energy for igniting fusion targets; (2) …

Particle-beam fusion research facilities at Sandia National Laboratories
Sandia research in inertial-confinement fusion (ICF) is based on pulse-power capabilities that grew out of earlier developments of intense relativistic electron-beam (e-beam) radiation sources for weapon effects studies. ICF involves irradiating a deuterium-tritium pellet with either laser light or particle beams until the center of the pellet is compressed and heated to the point of nuclear fusion. This publication focuses on the use of particle beams to achieve fusion, and on the various facilities that are used in support of the particle-beam fusion (PBF) program.

TIGER -- A technology to improve the delivery capability of nuclear bombs and the survivability of the delivery aircraft
The TIGER (Terminal guided and Extended-Range) Program was initiated in 1972 to study improved delivery capabilities for stockpiled tactical nuclear bombs. The Southeast Asia conflict fostered the development of air-delivered standoff conventional weapons utilizing terminal guidance systems. SNL initiated the TIGER program to determine if current nuclear bombs could be provided with a similarly accurate standoff capabilities. These conventional weapon delivery techniques, while allowing highly accurate attack, generally require entering the target area at high altitude to establish line of sight to the target. In parallel with the TIGER program, system studies analyzed this concept and showed marked improvement in aircraft and weapon survivability with moderate standoff (10--20 km) if low level deliveries (60 m) could be accomplished. As a result of this work, the TIGER program was redirected in early 1974 to demonstrate a standoff bomb with good accuracy (90 m CEP) when delivered from low flying aircraft. This program redirection resulted in the selection of an inertial guidance system to replace the earlier terminal guidance systems. This program was called the Extended-Range Bomb (ERB). In May 1974, a joint Air Force/DOE study identified the desirability of having a single tactical weapon which could be employed against either fixed, …

Volcanic hazards: Perspectives from eruption prediction to risk assessment for disposal of radioactive waste
This document summarizes an oral presentation that described the potential for volcanic activity at the proposed Yucca Mountain, Texas repository site. Yucca Mountain is located in a broad zone of volcanic activity known as the Death Valley-Pancake Ridge volcanic zone. The probability estimate for the likelihood that some future volcanic event will intersect a buried repository at Yucca Mountain is low. Additionally, the radiological consequences of penetration of a repository by basaltic magma followed by eruption of the magma at the surface are limited. The combination of low probability and limited consequence suggests that the risk posed by waste storage at this site is low. (TEM)

Heating facilities, Blue Mountain Community College, Pendleton, Oregon
Blue Mountain Community College campus consists of five major buildings totalling about 193,000 square feet in area. Four of these buildings are heated using hot water circulating systems, and the fifth by a low pressure steam system. The boilers for each of the systems are natural gas fired. A successful agricultural well was drilled adjacent to the campus, which during a twelve hour test produced 780 gallons per minute of 65/sup 0/F water. It was concluded that heating the campus utilizing a heat pump system is possible using readily available and proven equipment. Annual energy saving in natural gas will amount to 98,400 therms. This is an 82% reduction in the annual usage forecast after implementation of recommendations made as a result of the energy audit. The first year value of the natural gas saved is $49,200. This savings, less operating costs, when applied with escalation consideration over a period of twenty years, indicates that a capital investment of $367,500 can be justified. This assumes the project would be financed with 8% tax-free bonds. A system design was developed, new equipment sized, needed modifications identified, and major items estimated.
