Case study of the Wendel-Amedee Exploration Drilling Project, Lassen County, California, User Coupled Confirmation Drilling Program
The Wendel-Amedee KGRA is located in Honey Lake basin in Lassen County, California, on the boundary between the Modoc Plateau and the Basin and Range geologic provinces. A variety of geophysical surveys was performed over the project property. Geophysical data helped in establishing the regional structural framework, however, none of the geophysical data is sufficiently refined to be considered suitable for the purpose of siting an exploration drill hole. Drilling of reservoir confirmation well WEN-1 took place from August 1 to September 22, 1981. Pulse and long-term flow testing subjected the reservoir to a maximum flow of 680 gpm for 75 hours. At that rate, the well exhibited a productivity index of 21.6 gpm/psi; the reservoir transmissivity was 3.5 x 10/sup 6/ md-ft/cp. The maximum bottom-hole temperature recorded during testing was 251/sup 0/F. The conceptual model of the geothermal resource at Wendel Hot Springs calls on ground water, originating in the neighboring volcanic highlands, descending through jointed and otherwise permeable rocks into the granitic basement. Once in the basement, the fluid is heated as it continues its descent, and lateral movement as dictated by the hydrologic gradient. It then rises to the discharge point along transmissive faults. 45 refs., 28 …

Distributed Microprocessor Automation Network for Synthesizing Radiotracers Used in Positron Emission Tomography
This presentation describes an evolving distributed microprocessor network for automating the routine production synthesis of radiotracers used in Positron Emission Tomography. We first present a brief overview of the PET method for measuring biological function, and then outline the general procedure for producing a radiotracer. The paper identifies several reasons for our automating the syntheses of these compounds. There is a description of the distributed microprocessor network architecture chosen and the rationale for that choice. Finally, we speculate about how this network may be exploited to extend the power of the PET method from the large university or National Laboratory to the biomedical research and clinical community at large. 20 refs.

Mixing, Chemical Reaction and Flow Field Development in Ducted Rockets
Calculations have been made of the three-dimensional mixing, chemical reaction, and flow field development in a typical ducted rocket configuration. The governing partial differential equations are numerically solved by an iterative finite-difference solution procedure. The physical models include the k approx. epsilon turbulence model, one-step reaction, and mixing controlled chemical reaction rate. Radiation is neglected. The mean flow structure, fuel dispersal patterns, and temperature field are presented in detail for a base configuration with 0.058 m (2 in.) dome height, 45/sup 0/ side arm inclination, and with gaseous ethylene injected from the dome plate at an eccentric location. In addition, the influences of the geometrical parameters such as dome height, inclination of the side arms, and location of the fuel injector are studied.

Accuracy of the Finite Analytic Method for Scalar Transport Calculations
The accuracy of the finite analytic method of discretizing fluid flow equations is assessed through calculations of multidimensional scalar transport. The transport of a scalar function in a uniform velocity flow field inclined with the finite-difference grid lines is calculated for a range of grid Peclet numbers and flow skewness. The finite analytic method is observed to be superior to the approach of constructing finite-difference analogs from locally one-dimensional resolution of the flow vector. However, the finite analytic method also produces appreciable errors locally in regions of steep variations, under conditions of large grid Peclet numbers, and skewness of the streamlines.

Flow-Induced Vibration of the SSME LOX Posts
Cracking of liquid-oxygen (LOX) posts was observed in several evaluation tests. The design modification consists of attaching impingement shields to LOX posts in the upstream row. This has improved the vibration/fatigue problem of LOX posts. However, that modification results in an increased pressure drop that ultimately affects the lifetime of other components. This report presents a preliminary assessment of the LOX post vibration problem including a review of relevant parameters, flow induced vibration mechanisms, scoping calculation and experiment, and a work plan for an integrated theoretical/experimental study.

The TRIO Experiment
The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an analytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion.

DISPL1: a Software Package for One and Two Spatially Dimensioned Kinetics-Diffusion Problems
DISPL1 is a software package for solving some second order nonlinear systems of partial differential equations including parabolic, elliptic, hyperbolic, and some mixed types such as parabolic-elliptic equations. Fairly general nonlinear boundary conditions are allowed as well as interface conditions for problems in an inhomogeneous media. The spatial domain is one or two dimensional with Cartesian, cylindrical, or spherical (in one dimension only) geometry. The numerical method is based on the use of Galerkin's procedure combined with the use of B-splines in order to reduce the system of PDE's to a system of ODE's. The latter system is then solved with a sophisticated ODE software package. Software features include extensive dump/restart facilities, free format input, moderate printed output capability, dynamic storage allocation, and three graphics packages.

Imprinting Salmon and Steelhead Trout for Homing, 1983 Annual Report of Research.
The National Marine Fisheries Service (NMFS), under contract to the Bonneville Power Administration, began conducting research on imprinting Pacific salmon and steelhead for homing in 1978. In the juvenile marking phase, over 4 million juvenile salmon and steelhead were marked and released in 23 experiments. The primary objectives were to determine a triggering mechanism to activate the homing imprint, if a single imprint or a sequential imprint is necessary to assure homing, and the relationship between the physiological condition of fish and their ability to imprint. Ten experimental studies are discussed. Six of the studies employed a variety of techniques for imprinting fish. The remaining four tested the feasibility of imprinting fish by a short-distance voluntary migration before transport. In five experiments, survival was enhanced by the imprint-transportation procedures, and homing to the homing site area was partly successful. Returns from the Astoria, Oregon, release of fall chinook salmon from Big Creek Hatchery (Knappa, Oregon), for example, showed that limited short distance migration imprinting should provide 2-3 time more fish to the various fisheries while providing adequate returns to the hatchery for egg take each year. 21 refs., 12 figs, 12 tabs.

IN-SITU MEASUREMENT OF WALL THERMAL PERFORMANCE: DATAINTERPRETATION AND APPARATUS DESIGN RECOMMENDATIONS
Although the U-values of many building materials have been determined by laboratory testing, the in-situ thermal performance of walls, under either static or dynamic conditions, is not so well documented. This report examines the use of field measurements of heat flow and surface temperatures to determine the dynamic as well as static thermal performance of walls. The measurement strategies examined include both active devices, which generate their own heat fluxes on the wall surfaces, and passive devices, which rely on the weather to induce the required fluxes and temperature differences. Data obtained with both devices are analyzed with the Simplified Thermal Parameter (STP) model, which was designed to characterize a wall from flux and temperature measurements rather than from assumed material characteristics. The active measurement data are also analyzed with a modified version of the STP model that takes into account lateral heat losses. Some possible sources of error for both active and passive measurement strategies are also examined, and recommendations for both measurement strategies are given.
