Fabrication and characterization of uranium-6--niobium alloy plate with improved homogeneity

Description: Chemical inhomogeneities produced during arc melting of uranium--6 weight percent niobium alloy normally persist during fabrication of the ingot to a finished product. An investigation was directed toward producing a more homogeneous product (approx. 13.0-mm plate) by a combination of mechanical working and homogenization. Ingots were cast, forged to various reductions, homogenized under different conditions, and finally rolled to 13.0-mm-thick plate. It was concluded that increased forging reductions prior to homogenization resulted in a more homogeneous plate. Comparison of calculated and experimentally measured niobium concentration profiles indicated that the activation energy for the diffusion of niobium in uranium--niobium alloys may be lower than previously observed.

Fatigue life of LOFT reactor vessel components

Description: This report provides calculated LOCE lifetimes of the LOFT reactor vessel components. For each component, lifetime is defined as the greatest number of LOCE transient cycles and/or other non-LOCE transient cycles such that cumulative usage factor does not exceed 1.0. The results are presented in tabular form. The results indicate that transients other than LOCE transients govern with or instead of LOCE transients for some components. The other transients are shown in the results.

LOFT primary coolant addition and Control Piping System stress analysis

Description: A stress analysis was performed on the Primary Coolant Addition and Control Piping System to determine if it met the conditions of the ASME Code, Section III, for Class 2 components. Results indicate that the Addition and Control System does not meet Section III criteria as the system is now installed. Only hanger (support) modifications are required to bring the stresses within the limits set forth in the Code. A design temperature of 459/sup 0/F was assumed for the analysis. The specified design temperature of 650/sup 0/F has been revised by ECRA's L-5713 and L-5714.

Silicon on ceramic process. Silicon sheet growth and device development for the large-area silicon sheet and cell development tasks of the Low-Cost Solar Array Project. Annual report No. 3, September 20, 1977--September 29, 1978

Description: The objective of this research program is to investigate the technical and economic feasibility of producing solar-cell-quality sheet silicon by coating one surface of carbonized ceramic substrates with a thin layer of large-grain polycrystalline silicon from the melt. During the past year, the cell development task of the low-cost solar array project has also sponsored work leading to the solution of solar-cell-oriented problems unique to silicon-on-ceramic material. This work is described also. Fracture toughness and thermal shock measurements were made on various mullite compositions. The dip-coater experimentation involved using a variety of crucible positions and gas flow rates to improve coating speeds. The construction of the continuous coating facility was completed. Many modifications to the original design have been made to obtain better control of the temperature profile of the coater. An experimental dip-coater has been completed. The goal of this effort is to increase coating speeds to from 0.15 to 0.3 cm/sec without sacrificing material quality. The best slotted SOC cell fabricated to date has a 7.5 percent conversion efficiency (antireflective-coated, AM1, total area 4.1 cm/sup 2/). A standardized cell fabrication process was developed for slotted and unslotted SOC solar cells. Modeling activities have concentrated on three major areas: silicon growth, device design, and economic analysis. An economic projection was made using standard SAMICS procedures which indicated the target cost of $18/m/sup 2/ for silicon sheet could be met for certain SOC manufacturing conditions.

Western Gas Sands Project status report

Description: This edition of the WGSP status report summarizes September 1978 progress of the government-sponsored projects directed towards increasing gas production from the low-permeability gas sands of the western United States. Background information is provided in the September 1977 Status Report, NVO/0655-100. The Williston Basin Symposium was held in Billings, Montana, the 24th through the 27th of September 1978. The USGS continued work on characterization and assessment of the resource in the four primary study areas and completed the 1978 field work in the Sand Wash and Green River Basins. CER Corporation is evaluating a Twin Arrow drill site, located on the Douglas Creek Arch for the possibility of obtaining core, and preparations are being made for the Logging Program meeting to be held at the CER offices the latter part of October, 1978. The design phase for the pressure coring system has been completed and work is progressing on the fabrication and testing of the improved system. The National Laboratories and Energy Technology Centers continued work on mathematical model development, new tools and instrumentation systems, data analysis techniques and rock mechanics. Work continued on the field tests and demonstrations aspect of the WGSP. Bids sent to several service companies by Mitchell Energy Corporation, for a massive fracture treatment, are due back in October and the treatment is expected to be performed in mid-November. Mobil Research and Development fractured Zone 8 of their PCU 31-13 well, then shut it in due to anticipated winter weather and work was started on Zone 9. Sandia's mineback program involved evaluation of the Hole No. 6 Formation Interface Fracture Experiment.

Safety margins associated with containment structures under dynamic loading. [BWR Mark I]

Description: A technical basis for assessing the true safety margins of containment structures involved with MARK I boiling water reactor reevaluation activities is presented. It is based on the results of a plane-strain, large displacement, elasto-plastic, finite-element analysis of a thin cylindrical shell subjected to external and internal pressure pulses. An analytical procedure is presented for estimating the ultimate load capacity of the thin shell structure, and subsequently, for quantifying the design margins of safety for the type of loads under consideration. For defining failure of structures, a finite strain failure criterion is derived that accounts for multiaxiality effects.

Program plan for molten carbonate fuel-cell systems development

Description: The purpose of this document is to describe in both programmatic and technical terms the methodology that the US Department of Energy will use to commercialize a molten carbonate fuel cell power plant. Responsibility for the planning and management of the program resides in the molten carbonate fuel cell program office at the Argonne National Laboratory which reports to the Assistant Director for Fuel Cells in the Division of Fossil Fuel utilization of DOE/FE. The actual development of technology is carried out by selected contractors. The technology development phase of the program will culminate with the construction and operation of two demonstration power plants. The first power plant will be an industrial cogeneration plant which will be completed in 1987. The other power plant will be a baseload electric power plant to be completed in 1989.

Thin film battery/fuel cell power generating system. Second quarterly report, July 1, 1978-September 30, 1978

Description: Progress is reported on the development of the high-temperature solid-oxide electrolyte fuel cell. Oxygen loss behavior in the lanthanum chromite interconnection material was investigated by the microweighing technique. RF sputtered interconnection bands have been produced that display suitable density to permit the technique to be used in the construction of cell stacks. Electrochemical vapor deposition equipment has been modified to enable preparation of 20 cell fuel cell stack fabrication to proceed. The fuel electrode process and equipment have been improved to permit fabrication of long (0.3 m) tube segments, showing good mechanical and electrical properties. Long tube sections have been used to fabricate air electrodes, having desired porosity without loss of conductivity. Porous support tube work (involving equipment and fabrication techniques) is being extended to the fabrication of 0.3 m long tubes, needed for the fabrication of the 20 cell stacks. Work continues on the construction of the 5 station fuel cell stack life test facility. Theoretical interpretations of fuel cell stack polarization losses have been compared with actual measured losses in the 5 cell fuel cell stack previously tested in the program. Analyses of the intercell leakage current in the five cell fuel cell stack that was life tested for 700 hours were conducted. (WHK)
