Managing for success: developing and exploiting international opportunities in geothermal energy

Description: This study is designed to assist the Division of Geothermal Energy (DGE) in deciding what kind of strategy it wants and needs in order to make its international effort as cost-effective and appropriate as possible. The purpose of this study is to construct a logic base on which DGE can, in turn, establish its own strategy for international cooperation, and can begin to plan for necessary organization, procedural and policy reforms. This report will constitute a set of decision guidelines for DGE to consider in determining the nature of future strategy-related reforms. Each chapter asks, and then answers, the question on which it is centered as follows: (1) what are the deficiencies in DGE's current approach; (2) what should an international strategy for DGE ensure; (3) how can an international strategy for DGE be manifested; (4) which strategic model presents the best opportunity now; and (5) how can the recommended alternative be achieved.

Probability of spent fuel transportation accidents

Description: The transported volume of spent fuel, incident/accident experience and accident environment probabilities were reviewed in order to provide an estimate of spent fuel accident probabilities. In particular, the accident review assessed the accident experience for large casks of the type that could transport spent (irradiated) nuclear fuel. This review determined that since 1971, the beginning of official US Department of Transportation record keeping for accidents/incidents, there has been one spent fuel transportation accident. This information, coupled with estimated annual shipping volumes for spent fuel, indicated an estimated annual probability of a spent fuel transport accident of 5 x 10/sup -7/ spent fuel accidents per mile. This is consistent with ordinary truck accident rates. A comparison of accident environments and regulatory test environments suggests that the probability of truck accidents exceeding regulatory test for impact is approximately 10/sup -9//mile.

Characterization of geothermal solid wastes

Description: The compositions of 5 major types of geothermal wastes have been determined, and samples have been subjected to EPA recommended extraction tests to determine if they contain toxic metals that would classify the wastes as hazardous. Of the samples tested, the extracts of geothermal brines clearly contain levels of As, Ba and Pb exceeding the maximum allowed concentrations that characterize wastes as toxic. Only one other waste type, geothermal scale, exhibited EP toxicity. Pb was found in the extract of geothermal scale at a level of 7 mg/l, only 2 mg/l over the maximum limit. All of the other types of geothermal waste samples showed levels of toxic metals in the extracts well below the regulated limits.

Survey of existing underground openings for in-situ experimental facilities

Description: In an earlier project, a literature search identified 60 underground openings in crystalline rock capable of providing access for an in-situ experimental facility to develop geochemical and hydrological techniques for evaluating sites for radioactive waste isolation. As part of the current project, discussions with state geologists, owners, and operators narrowed the original group to 14. Three additional sites in volcanic rock and one site in granite were also identified. Site visits and application of technical criteria, including the geologic and hydrologic settings and depth, extent of the rock unit, condition, and accessibility of underground workings, determined four primary candidate sites: the Helms Pumped Storage Project in grandiodorite of the Sierra Nevada, California; the Tungsten Queen Mine in Precambrian granodiorite of the North Carolina Piedmont; the Mount Hope Mine in Precambrian granite and gneiss of northern New Jersey; and the Minnamax Project in the Duluth gabbro complex of northern Minnesota.

Brayton-cycle heat-recovery-system characterization program. Gas-conditioning final evaluation report

Description: Flue gas conditioning approaches for the Brayton-cycle heat recovery system are discussed. This revision incorporates the results of recent AiResearch tests on the subatmospheric system (SAS) turbocompressor, as well as the Electric Power Research Institute sponsored tests on ceramic fiber filters. The two primary purposes of the gas conditioning evaluation are: to determine the need for protecting the Brayton-cycle turbocompressor and heat exchanger from the potential damaging effects of erosion and deposition, and to determine what type of approach should be used for cleanup, if protection by flue gas conditioning is required.

Wet cooling towers: rule-of-thumb design and simulation

Description: A survey of wet cooling tower literature was performed to develop a simplified method of cooling tower design and simulation for use in power plant cycle optimization. The theory of heat exchange in wet cooling towers is briefly summarized. The Merkel equation (the fundamental equation of heat transfer in wet cooling towers) is presented and discussed. The cooling tower fill constant (Ka) is defined and values derived. A rule-of-thumb method for the optimized design of cooling towers is presented. The rule-of-thumb design method provides information useful in power plant cycle optimization, including tower dimensions, water consumption rate, exit air temperature, power requirements and construction cost. In addition, a method for simulation of cooling tower performance at various operating conditions is presented. This information is also useful in power plant cycle evaluation. Using the information presented, it will be possible to incorporate wet cooling tower design and simulation into a procedure to evaluate and optimize power plant cycles.

Brayton-cycle heat recovery-system characterization program. Subatmospheric-system test report

Description: The turbine tests and results for the Brayton cycle subatmospheric system (SAS) are summarized. A scaled model turbine was operated in the same environment as that which a full-scale SAS machine would experience from the hot effluent flue gas from a glass container furnace. The objective of the testing was to evaluate the effects of a simulated furnace flue gas stream on the turbine nozzles and blades. The following specific areas were evaluated: erosion of the turbine nozzles and blades from the dust in the flue gas, hot corrosion from alkali metal salts in the dust and acid vapor (sulfur trioxide and hydrogen chloride) in the flue gas, and fouling and flow blockage due to deposition and/or condensation from the flue gas constituents.

Review of the neutron capture process in fission reactors

Description: The importance of the neutron capture process and the status of the more important cross section data are reviewed. The capture in fertile and fissile nuclei is considered. For thermal reactors the thermal to epithermal capture ratio for /sup 238/U and /sup 232/Th remains a problem though some improvements were made with more recent measurements. The capture cross section of /sup 238/U in the fast energy range remains quite uncertain and a long standing discrepancy for the calculated versus experimental central reaction rate ratio C28/F49 persists. Capture in structural materials, fission product nuclei and the higher actinides is also considered.

Conceptual design of a laser fusion power plant. Part I. An integrated facility

Description: This study is a new preliminary conceptual design and economic analysis of an inertial confinement fusion (ICF) power plant performed by Bechtel under the direction of Lawrence Livermore National Laboratory (LLNL). The purpose of a new conceptual design is to examine alternatives to the LLNL HYLIFE power plant and to incorporate information from the recent liquid metal cooled power plant conceptual design study (CDS) into the reactor system and balance of plant design. A key issue in the design of a laser fusion power plant is the degree of symmetry in the illumination of the target that will be required for a proper burn. Because this matter is expected to remain unresolved for some time, another purpose of this study is to determine the effect of symmetry requirements on the total plant size, layout, and cost.

Geophysical reconnaissance of prospective geothermal areas on the island of Hawaii using electrical methods

Description: Resistivity data from several areas were compiled, analyzed, and interpreted in terms of possible geologic models. On the basis of this analysis alone, two areas have been ruled out for possible geothermal exploitation, two have been interpreted to have a moderate-temperature resource, and two have been interpreted to have a high-temperature resource. The two areas which have been ruled out are the Keaau and South Point areas. The Kawaihae area and the lower northwest rift zone of Hualalai appear to have anomalous resistivity structures, which suggest a moderate-temperature resource in each of these areas. Finally, specific areas in the lower southwest and lower east rift zones of Kilauea have been outlined as locations where high-temperature fluids may exist at depth.
