Acceptability of risk from radiation: Application to human space flight
This one of NASA`s sponsored activities of the NCRP. In 1983, NASA asked NCRP to examine radiation risks in space and to make recommendations about career radiation limits for astronauts (with cancer considered as the principal risk). In conjunction with that effort, NCRP was asked to convene this symposium; objective is to examine the technical, strategic, and philosophical issues pertaining to acceptable risk and radiation in space. Nine papers are included together with panel discussions and a summary. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

Application of Advanced Reservoir Characterization, Simulation, and Production Optimization Strategies to Maximize Recovery in Slope, and Basin Clastic Reservoirs, West Texas (Delaware Basin)
The objective of this project is to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost effective way to recover a higher percentage of the original oil in place through strategic placement of infill wells and geologically based field development. Project objectives are divided into two major phases. The objectives of the reservoir characterization phase of the project are to provide a detailed understanding of the architecture and heterogeneity of two fields, the Ford Geraldine unit and Ford West field, which produce from the Bell Canyon and Cherry Canyon Formations, respectively, of the Delaware Mountain Group and to compare Bell Canyon and Cherry Canyon reservoirs. Reservoir characterization will utilize 3-D seismic data, high-resolution sequence stratigraphy, subsurface field studies, outcrop characterization, and other techniques. Once the reservoir-characterization study of both fields is completed, a pilot area of approximately 1 mi 2 in one of the fields will be chosen for reservoir simulation. The objectives of the implementation phase of the project are to (1) apply the knowledge gained from reservoir characterization and simulation studies to increase recovery from the …

Application of reservoir characterization and advanced technologies to improve recovery and economics in a lower quality shallow shelf Sand Andreas Reservoir: Quarterly technical report, January 1, 1997--March 31, 1997
The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: l.Advanced petrophysics 1547 2.Three-dimensional (3-D) seismic 3.Cross-well bore tomography 4.Advanced reservoir simulation 5.Carbon dioxide (CO{sub 2}) stimulation treatments 6.Hydraulic fracturing design and monitoring 7. Mobility control agents SUMMARY OF TECHNICAL PROGRESS West Welch Unit is one of four large waterflood units in the Welch Field in the northwestern portion of Dawson County, Texas. The Welch Field was discovered in the early 1940`s and produces oil under a solution gas drive mechanism from the San Andres formation at approximately 4800 ft. The field has been under waterflood for 30 years and a significant portion has been infill-drilled on 20-ac density. A 1982- 86 Pilot C0{sub 2} injection project in the offsetting South Welch Unit …

Demonstration and evaluation of the CORPEX{trademark} Nuclear Decontamination Process, Technical task plan No. SR152005. Final Report
In June, 1995, the Decontamination and Decommissioning Focus Area funded a demonstration of the CORPEX Nuclear Decontamination Process in an Old Metallography Laboratory glovebox at the Savannah River Site. The objective of the demonstration was to prove the effectiveness of a new and innovative technology that would reduce the risks associated with future cleanups of plutonium-238 contaminated equipment in the DOE complex. After facility and vendor preparations in support of the demonstration, Westinghouse Savannah River Company (WSRC) was informed by the vendor that the chemistry proposed for use in the decontamination process was not effective on sintered plutonium, which was the form of plutonium in the selected glovebox. After further technical evaluation, the demonstration was canceled. This report describes the work performed in support of the demonstration and the present status of the project. The CORPEX chemical process is a nondestructive cleaning method that removes only the contaminant and the matrix that fixed the contaminant to the surface. It does not damage the substrate. The cleaning agent is destroyed by the addition of proprietary oxidizers, leaving water, carbon dioxide and nitrogen gases, and a sludge as waste.

Development of a Phenomenological Model for Coal Slurry Atomization
Task I - Extensional Viscometer - A contracting flow extensional viscometer was designed and constructed at Adelphi University. Calibration was conducted using a variety of fluids and suspensions. Task 2 - Testing using the extensional viscometer was performed using simulated fluids. Testing was performed using coal water slurries with dispersant and/ or stabilizer to determine the concentration and shear dependence and the effect of additives. Viscoelastic effects were evaluated using simulated fluids. Testing with coal at three coal concentrations to determine dependence will begin shortly. Task 3 - Extension of the Phenomenological Model - The phenomenological model is being extended to include extensional and viscoelastic properties. Task 4 - Development of Active Model for Atomization - A bench scale atomization study is being conducted using simulated fluids and coal water slurries to determine the parameters on which the model is dependent. Based on these results, a model is being developed for the Sauter mean diameter. A statistical analysis of atomization data will relate the PSD to the dimensionless parameters.

Development of Precipitated Iron Fischer-Tropsch Catalysts
Four (alumina or silica) supported catalysts were prepared by conventional impregnation of two commercial supports (silica - Davison grade 952; and alumina - Vista B). Nominal compositions (on mass basis) of synthesized catalysts are: (1) 100 Fe/5 Cu/6 K/139 SiO{sub 2} (2) 100 Fe/10 Cu/6 K/134 SiO{sub 2}, (3) 100 Fe/5 Cu/6 K/139 Al{sub 2}0{sub 3} and (4) 100 Fe/10 Cu/6 K/134 Al{sub 2}0{sub 3}. The corresponding weight % of iron (as metal) in the prepared catalysts is about 33.8%. Reduction behavior of the four supported catalysts was studied by both temperature programmed and isothermal reduction in hydrogen, and by isothermal reduction in CO at 280{degrees}C. Also, two precipitated promoted iron catalysts containing aluminum oxide as a binder, were reduced isothermally in the TGA unit with hydrogen at 240{degrees}C and 280{degrees}C. One of the two alumina containing catalysts (100 Fe/5 Cu/4.2 K/20 Al{sub 2}0{sub 3}) was tested in a slurry reactor (run SA-0097), and catalyst samples withdrawn from the reactor at various times on stream were characterized by XRD to determine bulk iron phases in the catalyst. Two slurry reactor tests were completed during this quarter. The first test (SA-0097) was conducted with alumina containing catalyst with nominal composition 100 …

ELECTROKINETIC DENSIFICATION OF COAL FINES IN WASTE PONDS
The objective of this research is to demonstrate that electrokinetics can be used to remove colloidal coal and mineral particles from coal-washing ponds and lakes without the addition of chemical additives such as salts and polymeric flocculants. In this experimental and analytical study the authors elucidate the transport processes that control the rate of concentrated colloidal particle removal, demonstrate the process on a laboratory scale, and develop the scale-up laws needed to design commercial-scale processes. They then address the fundamental problems associated with particle-particle interactions (electrical and hydrodynamic), the effects of particle concentration on the applied electric field, the electrochemical reactions that occur at the electrodes, and the prediction of power requirements.

Engineering Annual Summary 1996
Fiscal year 1996 has been a year of significant change for the Lawrence Livermore National Laboratory (LLNL) in general and for Engineering in particular. Among these changes, the Laboratory`s national security mission was better defined, the stockpile stewardship program objectives became crisper, LLNL`s investment in high-performance computing was re-emphasized with the procurement of a $100 million supercomputer for the Laboratory`s Accelerated Strategic Computing Initiative (ASCI) program, two major Laser programs (the National Ignition Facility and Atomic Vapor Laser Isotope Separation) expanded significantly, and DOE`s human genome efforts moved to the next phase of development. In the area of business operations, LLNL`s Cost Cutting Initiative Program (CCIP) was completed and the Laboratory restructured its workforce using a Voluntary Separation Incentive Program (VSIP). Engineering similarly also saw many technical and programmatic successes, as well as changes, starting with completion of its strategic plan, significant consolidation of its facilities, restructuring of its workforce, reduction of its overhead costs, substantial transfers of staff between programs, and finally my personal arrival at Livermore. This report is the first opportunity to capture some of Engineering`s FY96 activities and accomplishments in a succinct fashion, and to relate these to our strategic plan.

Extensions of the longitudinal envelope equation
Recently, longitudinal space charge effects have become of increased importance in a variety of dynamical situations. The CEBAF FEL injector beam dynamics shows large space-charge effects, even at 10 MeV ({gamma} {approx} 20). Space-charge dominated longitudinal motion has also been studied in the IUCF ion storage ring. Previously a longitudinal envelope equation with a self-consistent phase-space distribution has been developed, and has been of considerable use in analyzing the motion of these cases. Longitudinal motion in detailed agreement with this envelope equation has been observed at the U. of Maryland Laboratory for Plasma Research, and at the GSI electron cooling storage ring ESR, as well as at the IUCF. However, the initial presentation in ref. 4 used non-relativistic linear-accelerator bunching motion as a simplifying approximation in order to avoid inadvertent errors and minimize misprints, and must be adapted to include relativistic and/or synchrotron effects. In the present note we extend the envelope equation formulae to include relativistic, synchrotron, and acceleration effects, and define the various factors in the equations in explicit detail. The object is to obtain a set of debugged formulae for these extended cases, with all of the various factors defined explicitly, so that the formulae can be …
