A comparison of background and potential geopressured geothermal development-related subsidence rates is given. Estimated potential geopressured-related rates at six prospects are presented. The effect of subsidence on the Texas-Louisiana Gulf Coast is examined including the various associated ground movements and the possible effects of these ground movements on surficial processes. The relationships between ecosystems and subsidence, including the capability of geologic and biologic systems to adapt to subsidence, are analyzed. The actual potential for environmental impact caused by potential geopressured-related subsidence at each of four prospects is addressed. (MHR)

A test has been performed at the Paducah Gaseous Diffusion Plant (PGDP) in connection with studies for the US Arms Control and Disarmament Agency on the possibility of utilizing measurements of the concentrations of the minor uranium isotopes in /sup 235/U enrichment cascade external streams as a safeguards technique (MIST). This is the fourth plant test that has been performed in connection with the MIST studies, the first three having been done at the Oak Ridge Gaseous Diffusion Plant (ORGDP). The main objectives of the test were to measure the isotopic composition and flow rates of the plant external streams over a period of time; to design an appropriate plant model in the manner an IAEA safeguards team might do it and calculate the isotopic compositions of the plant streams; and to compare the calculated isotopic values with the measured ones. The calculated /sup 235/U to /sup 234/U concentration ratios in the product and tails streams did not match the average measured values in the high-power period as well as they did for the low-power period, when the same isotopic composition for natural U was assumed at both power levels - the actual composition of the natural U fed to …

Predictions of near-surface (10 to 100 m) wind velocities made by a mesoscale numerical model on a 10 km grid over and near the coastline are checked against observations. Two comparisons are made. The first is between observed and model-estimated mean annual wind power density at locations where surface observations exist in three coastal areas: the Chesapeake Bay, the Apalachee Bay and the South Texas coastal area. The second comparison is made between model predictions over the Delmarva Peninsula and adjacent ocean and observations made over a 120 x 30 km rectangle extending across the peninsula and out to sea. It is concluded that the unbiased error analysis skill ratings of 81% and 76% are attained for two days of prediction-observation comparisons. In the meantime, the skill of the model in duplicating individual coastal wind fields is taken as 78%. In addition, a qualitative comparison is made between the predicted fields of wind and the observed wind field. The predicted wind field unquestionably reproduces the observed field.

There is no need to provide individual compensation for the detector solenoid. The correction skew quads which correct for the skew quad errors should take care of the detector solenoid. (GHT)

The formulation needed for the conductance of heat by means of explicit integration is presented. The implementation of these expressions into a transient structural code, which is also based on explicit temporal integration, is described. Comparisons of theoretical results with code predictions are given both for one-dimensional and two-dimensional problems. The coupled thermal and structural solution of a concrete crucible, when subjected to a sudden temperature increase, shows the history of cracking. The extent of cracking is compared with experimental data.

A method has been developed to analyze one- and two-dimensional, nonlinear current diffusion in rail-gun conductors. A nonlinear current-diffusion equation that accounts for the temperature dependence of electrical conductivity has been developed from Maxwell's equations. A finite-difference heat-transfer computer program was adapted to solve the current-diffusion and thermal-diffusion problems for rail-gun conductors in one and two dimensions. The nonlinear current-diffusion equation was also extended to account for the magnetic-field dependence of the magnetic permeability, thus allowing ferromagnetic materials to be considered. A one-dimensional finite-difference technique was developed for ferromagnetic materials. Two one-dimensional test problems that compare results with other analyses are discussed. A series of calculations of current density and rail temperature was done for various size rectangular rails. One analysis of current diffusion in a ferromagnetic material was also performed.

The application of positron annihilation spectroscopy (PAS) to the study of defects in metals has led to increased knowledge on lattice-defect properties during the past decade in two areas: the determination of atomic defect properties, particularly those of monovacancies, and the monitoring and characterization of vacancy-like microstructure development during post-irradiation and post-quench annealing. The study of defects in metals by PAS is reviewed within the context of the other available techniques for defect studies. The strengths and weaknesses of PAS as a method for the characterization of defect microstructures are considered. The additional possibilities for using the positron as a localized probe of the atomic and electronic structures of atomic defects are discussed, based upon theoretical calculations of the annihilation characteristics of defect-trapped positrons and experimental observations. Finally, the present status and future potential of PAS as a tool for the study of defects in metals is considered. 71 references, 9 figures.

Proposal F-602 is a demonstration of a commercially available wind-electric device - an Enertech Corp. Series 1800 model wind turbine. The demonstration site selected was the New Directions school campus, a public school facility, in Sarasota, Florida. During testing, an investigation of the wind power potential for the area was undertaken. In addition, negotiations with the Florida Power and Light Company for parallel operation of the wind system (utility interface), were initiated. An Operating Agreement contract is now pending approval by the Sarasota County School Board. The results to date, of this site's wind power potential, have been well below computational expectancies based upon wind speed data for the area. Analysis will continue, to determine the cause of the windplant's low net output.

The D-T burn time for advanced laser-fusion targets is calculated to be very short, < 50 ps. We describe the design of a neutron streak camera of 16 ps resolving time that can be used to study the temporal history of fusion burn. The cathode of the neutron streak camera is sensitive to neutrons and is curved such that the difference in the neutron path lengths from a point source to various parts of the cathode is compensated by electron transit times within the streak tube. Thus the cathode can be made large for high sensitivity, without sacrificing time resolution. The cathode is coated with 1 ..mu..m UO/sub 2/. Each fission fragment leaving the cathode generates 400 secondary electrons that are all < 20 eV. These electrons are focussed to a point with an extractor and an anode, and are then purified with an electrostatic deflector. The electron beam is streaked and detected with the standard streak camera techniques. Careful shielding is needed for x-rays from the fusion target and general background. It appears that the neutron streak camera can be a viable and unique tool for studying temporal history of fusion burns in D-T plasmas of a few keV …

The BEACON process involves the catalytic deposition of carbon from a gas stream containing carbon monoxide, and subsequent exposure of this carbon to a gas stream containing hydrogen or steam at elevated temperature and pressure to produce methane. The steam gasification route currently is receiving the most attention. Multiple-cycle tests with K1 and K2 catalysts showed sustained activity and stable performance through thirty of the planned forty cycles. The tests will be completed next quarter. Steaming temperature screening tests on K2-based BEACON carbon supported the conclusion based on earlier testing with K1-based BEACON carbon that steam gasification at two temperature levels has significant advantages over steam gasification at a single temperature in terms of gasification rates and methane yields. Multiple-cycle testing of K2-based BEACON carbon was started in the 4-inch bench-scale fluid bed reactor. Catalyst C77 continued to have problems during multiple-cycle testing - loss of catalytic activity, possibly due to overheating, and poor fluidizability. Further modifications of the C77 catalyst preparation technique were tested. Catalyst C77-K2 showed no change in performance, and results with catalyst C77-K1 were generally disappointing. Laboratory experiments continued with catalyst C78. A variable differential pressure concept which does not require gas/solids separtion is now being …

This report constitutes a formulation of a new concept for improving thermal-system performance by utilizing the combined mechanisms of enhanced heat transfer, transport, and thermal energy storage associated with a phase-change slurry as the working fluid. In addition, pertinent literature is surveyed and a quantitative scoping assessment of enhancement potential confirms concept merit. It has been determined that additional research and development is required in order to adequately understand the enhancement mechanisms to the degree that enhanced performance thermal systems using slurries can be designed. The concepts presented are identified as being new, rewarding research activities.

Work proceeded this quarter mainly under three program tasks. Under Task 1.0, work was started on preparing a description of the reference Steam Injection System. It is planned to lay out the plant in power unit trains rated at a nominal 100 MW(e). Under Task 2.0, work continued on anode, cathode, current collector, and electrolyte tile develoment and stack design and analysis. Corrosion test results of various current collector materials after 3500 hours exposure are reported. Sintering data at 6000 hours were obtained on twelve different material samples tested to evaluate the effects of chromium and ceramic addition to state-of-the-art and in-house fabricated electrodes. The 6000 hour data showed no change in porosity or pore distribution from the 5000 hour data. The electroless-plated ceramic plaques demonstrated good stability and porosities. Two cells containing dual porosity anodes using all metal-plated-ceramic material, were tested. Although testing was terminated due to cracked tiles, the cell results are encouraging for the experimental anodes. Under Task 4.0, work continued on installation and debugging of the atmospheric bench scale single cell test facility, and operation of a cell started on April 20, 1982. Progress is detailed. (WHK)

The Inyan Kara Formation provides an abundant source of warm (54 to 71/sup 0/C) but salty (7400 mg/l combined Na and Cl ions) water for much of southwestern North Dakota. The city of Dickinson, ND, overlies this aquifer at 1676 to 1768 meters. This study investigates the potential of usng this hydrothermal resource as an energy source for a district heating system in a new undeveloped addition to Dickinson. In addition, the use of a reverse osmosis system to desalinate the water is considered along with other water treatment processes necessary to allow use of this water in the existing city water supply. The results of the study indicate the economic requirements to make this concept feasible and outline the consideration to carry the project into the design phase.

From introduction: This study is part of a regional study of the Tertiary limestone aquifer system in the southeastern United States. The regional study encompasses all of Florida and extends into Georgia, Alabama, and South Carolina--a total area of about 82,000 square miles.

Using an integral equation numerical solution, the theoretical results for (1) the potential, (2) the apparent resistivity calculated from the total horizontal electric field, (3) the apparent resistivity calculated from the potential due to different three-dimensional bodies in plan and cross-section views have been computed. The transmitter consists of a remote electrode and a dowhole electrode embedded in the body or located near the body. For hole-to-surface work, the potential offers little information about the parameters of a deep body. The apparent resistivity from the total electric field, with its distinctive patterns, best resolves the width, length, and dip of the model, while the apparent resistivity from the potential is more difficult to interpret. The cross-section views, for analysis of hole-to-hole surveys, theoretically define the body for the potential and the apparent resistivity derived from the potential, but their use in practice is limited.

The techniques and models used in the study of rapid reactivity insertion in a BWR have ranged from approximate conservative methods with simple feedback models to detailed representations of coupled neutronic thermal-hydraulic mechanisms. In a recent paper Cheng and Diamond presented a detailed evaluation of the control rod drop accident (CRDA). Their calculations suggested that the effect of inlet subcooling and rod drop speed may play an important role in determining the severity of the rod drop accident. The purpose of the work summarized in this paper has been to determine in detail the dynamic behavior of a BWR core as the inlet moderator temperature and the speed of the dropped rod are varied.
