Heat pumps coupled to geothermal resources can provide economical process heat

Description: Temperatures available from geothermal resources are frequently too low to serve the needs of many process industries. Heat pumps can be used to boost the temperatures by moderate amounts at an economical cost. A number of potential working fluids were examined for service from 150/sup 0/F to 400/sup 0/F. Steam and R-11 were found to be the best choices. Comparison cost estimates were made for different bottom temperatures and delivery temperatures for both steam and R-11 systems. The results show that electricity to drive the compressor, capital investment in the compressor and in the geothermal resource all make significant contributions to the cost of process heat delivered by the heat pump.

Effects of controlled disturbance on ferruginous hawks as may occur during geothermal energy development

Description: The impacts on the ferruginous hawk of treatments designed to simulate those encountered during geothermal developments were assessed at the Raft River Geothermal Test Site. The objective of the study was to ascertain the tolerance limits of the disturbance-sensitive hawks to human- and development-related activities. Various impact treatments were imposed on 10 nests during the 1978 nesting season and 13 nests during 1979. Three nests were deserted in 1978 and four in 1979; treatment nests that successfully hatched eggs produced statistically fewer young than control nests. Data suggest that buffer zones of greater than or equal to 1.6 km around each nest be established to minimize deleterious impacts on this hawk species. Utilization of biological systems indicative of ecosystem stress is discussed.

Siting criteria as a function of sensitivity of nesting ferruginous hawks to geothermal development

Description: The ferruginous hawk has been studied over a number of years in the Raft River Valley area of south-central Idaho and consequently its population densities and dynamics are known. The ferruginous hawk is to be used as a barometer to the effects of human disturbance as might be found during geothermal development. It was proposed to determine what sort of buffer zones need to be established around the species to be compatible with the concepts of multiple use, and accumulate information and baseline data useful to such studies.

Approach to testing fusion components in existing nuclear facilities

Description: The concept presented makes use of the fast spectrum in the Engineering Test Reactor (ETR) at the Idaho National Engineering Laboratory (INEL). Preliminary results show that an asymmetric, nuclear test environment with particle and radiant energy fluxes impinging on a first wall/blanket or divertor surface appears feasible in a neutron/gamma field not greatly different from that seen by a representative first wall/blanket module.

Rugged, remotely maintainable pipetter using microprocessor control

Description: At the Idaho Chemical Processing Plant (ICPP), the chemical analysis of future nuclear fuel reprocessing solutions will require improved analytical apparatus. Remote pipetters are crucial components in the analysis procedures. Major improvements required for a new pipetter were: greater accuracy for better accounting of fissile material, greater corrosion resistance to handle new fuel reprocessing schemes, and drastic reduction in contact maintenance to reduce personnel radiation exposure to as low as reasonably achievable. The 20-year old Model B pipetter was used as the basis for an improved design. The existing pipetters are positive displacement, servo-controlled units developed from Oak Ridge National Laboratory (ORNL) designs created at the time the ICPP was built. The new pipetter is identified as the Model C.

Geothermal source potential and utilization for alcohol production

Description: A study was conducted to assess the technical and economic feasibility of using a potential geothermal source to drive a fuel grade alcohol plant. Test data from the well at the site indicated that the water temperature at approximately 8500 feet should approach 275/sup 0/F. However, no flow data was available, and so the volume of hot water that can be expected from a well at this site is unknown. Using the available data, numerous fuel alcohol production processes and various heat utilization schemes were investigated to determine the most cost effective system for using the geothermal resource. The study found the direct application of hot water for alcohol production based on atmospheric processes using low pressure steam to be most cost effective. The geothermal flow rates were determined for various sizes of alcohol production facility using 275/sup 0/F water, 235/sup 0/F maximum processing temperature, 31,000 and 53,000 Btu per gallon energy requirements, and appropriate process approach temperatures. It was determined that a 3 million gpy alcohol plant is the largest facility that can practically be powered by the flow from one large geothermal well. An order-of-magnitude cost estimate was prepared, operating costs were calculated, the economic feasibility of the propsed project was examined, and a sensitivity analysis was performed.

Geothermal source potential and utilization for methane generation and alcohol production

Description: A study was conducted to assess the technical and economic feasibility of integrating a geothermally heated anaerobic digester with a fuel alcohol plant and cattle feedlot. Thin stillage produced from the alcohol production process and manure collected from the cattle feedlot would be digested in anaerobic digesters to produce biogas, a mixture of methane and carbon dioxide, and residue. The energy requirements to maintain proper digester temperatures would be provided by geothermal water. The biogas produced in the digesters would be burned in a boiler to produce low-pressure steam which would be used in the alcohol production process. The alcohol plant would be sized so that the distiller's grains byproduct resulting from the alcohol production would be adequate to supply the daily cattle feed requirements. A portion of the digester residue would substitute for alfalfa hay in the cattle feedlot ration. The major design criterion for the integrated facilty was the production of adequate distiller's grain to supply the daily requirements of 1700 head of cattle. It was determined that, for a ration of 7 pounds of distiller's grain per head per day, a 1 million gpy alcohol facility would be required. An order-of-magnitude cost estimate was prepared for the proposed project, operating costs were calculated for a facility based on a corn feedstock, the economic feasibility of the proposed project was examined by calculating its simple payback, and an analysis was performed to examine the sensitivity of the project's economic viability to variations in feedstock costs and alcohol and distiller's grain prices.

Nonintrusive local density determination in discontinuous fields by gammas or neutrons

Description: In a wide diversity of systems, nonintrusive measurement of local density is of great importance. High temperature, aggressive fluids, or biological conditions often require the application of x rays, gammas, or neutrons. A method is needed which: (a) is applicable to any three-dimensional density field, without assumptions of continuity or density distribution types, (b) does not require integration, differentiation or long computing of recorded data, but utilizes algebraic expressions only, (c) scans the system at least along a line, and preferably across an area, (d) has a stationary measuring assembly, making it applicable to moving (flowing) and transient systems, with accuracy depending only on source strength, and (e) involves commercially available radiation sources and instrumentation. The new method reported, aimed to fulfill these conditions, uses two gamma detectors and a pair of sources.

Neodymium, samarium and europium capture cross-section adjustments based on EBR-II integral measurements

Description: Integral capture measurements were made for highly enriched isotopes of neodymium, samarium, and europium irradiated in a row 8 position of EBR-II with samples located both at mid-plane and in the axial reflector. Broad response, resonance, and threshold dosimeters were included to characterize the neutron spectra at the sample locations. The saturation reaction rates for the rare-earth samples were determined by post-irradiation mass-spectrometric analyses and for the dosimeter materials by the gamma-spectrometric method. The HEDL maximum-likelihood analysis code, FERRET, was used to make a least-squares adjustment of the ENDF/B-IV rare-earth cross sections based on the measured dosimeter and fission-product reaction rates. Preliminary results to date indicate a need for a significant upward adjustment of the capture cross sections for /sup 143/Nd, /sup 145/Nd, /sup 147/Sm, and /sup 148/Sm. 8 figures, 2 tables.
