Development of BEACON technology. Quarterly report, April-June 1982 (open access)

Development of BEACON technology. Quarterly report, April-June 1982

The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Experiments were continued this quarter with the objective of improving the carbon deposition efficiency using a Paraho retort off-gas mixture. Analysis has shown that the use of the Paraho off-gas to make hydrogen would be attractive if the ratio of the heat content of the feedgas to the heat content of the hydrogen produced is less than 3. Experimental conditions to achieve this ratio have been established. Recent work had shown that the volume of a BEACON supported catalyst bed increased with an increase in carbon loading level. Four series of experiments were performed where sieve analyses were made after one or more BEACON process cycles. These tests showed that the volume expansion is due to an increase in the number and size of the larger catalyst particles. The bench-scale testing of unsupported catalysts concentrated in two areas: (a) the completion of batch testing in the 4-inch reactor, and (b) the construction of the Tandem Reactor …

Critical Technology List update. Final technical report (open access)

Critical Technology List update. Final technical report

ICRC has reviewed and updated its List of critical technology. The List comprises all proposed SRC-I Demonstration Plant equipment whose use has been determined to involve some degree of potential safety, performance, or environmental risk. ICRC has subjected equipment on the Critical Technology c to special technical review to ensure the highest possible level of quality and lowest cost commensurate with acceptable overall risks. Equipment or equipment systems still considered to be high risk are the following: Coal Slurry/Hot Oil Heat Exchangers, Coal Slurry Heaters, Second-Stage Feed Heaters, Vacuum Tower Heater, Vacuum Column, SRC/Light SRC Stripper - CSD, Severe Service Valves, Wastewater Reuse System, and the Solid Waste Disposal System. Equipment systems or pieces of equipment that have been downgraded to a lower risk category are the following: Coal Weigh-Feed System, Coal Slurry Dissolvers, Coal Dissolver Effluent Separator, and LC-Fining Reactors. Finally, ICRC has determined that many types of equipment are no longer Critical Technology, and has therefore removed them from the List.

Mirror Fusion Test Facility: an intermediate device to a mirror fusion reactor (open access)

Mirror Fusion Test Facility: an intermediate device to a mirror fusion reactor

The Mirror Fusion Test Facility (MFTF-B) now under construction at Lawrence Livermore National Laboratory represents more than an order-of-magnitude step from earlier magnetic-mirror experiments toward a future mirror fusion reactor. In fact, when the device begins operating in 1986, the Lawson criteria of ntau = 10/sup 14/ cm/sup -3/.s will almost be achieved for D-T equivalent operation, thus signifying scientific breakeven. Major steps have been taken to develop MFTF-B technologies for tandem mirrors. Steady-state, high-field, superconducting magnets at reactor-revelant scales are used in the machine. The 30-s beam pulses, ECRH, and ICRH will also introduce steady-state technologies in those systems.

Effects of voltage control in utility interactive dispersed storage and generation systems (open access)

Effects of voltage control in utility interactive dispersed storage and generation systems

When a small generator is connected to the distribution system, the voltage at the point of interconnection is determined largely by the system and not the generator. This report examines the effect on the generator, on the load voltage and on the distribution system of a number of different voltage control strategies in the generator. Synchronous generators with three kinds of exciter control are considered, as well as induction generators and dc/ac inverters, with and without capacitor compensation. The effect of varying input power during operation (which may be experienced by generators based on renewable resources) is explored, as well as the effect of connecting and disconnecting the generator at ten percent of its rated power.

Ocean energy systems. Quarterly report, January-March 1983 (open access)

Ocean energy systems. Quarterly report, January-March 1983

Progress is reported on the development of Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual and preliminary design activity of industry teams that are designing a shelf-mounted offshore OTEC pilot plant that could deliver power to Oahu, Hawaii. In addition, a program is underway to evaluate and test the Pneumatic Wave-Energy Conversion System (PWECS), an ocean-energy device consisting of a turbine that is air-driven as a result of wave action in a chamber. This Quarterly Report summarizes the work on the various tasks as of 31 March 1983.

Development of On-Line Monitoring Device to Detect the Presence/Absence of Sodium Vapor (open access)

Development of On-Line Monitoring Device to Detect the Presence/Absence of Sodium Vapor

A process is being developed by the Sodium Waste Technology Program at ANL-W to remove metallic sodium from scrap and waste. The final step in the process is the removal of residual metallic sodium by evaporation at temperatures up to 482 C (900 F) and at pressures of about 10⁻² torr (1.3 Pa). Efficient operation of this process requires that the operators have a method to indicate the completion of the evaporation. This end point would signify when the chamber and scrap and waste is free of metallic sodium. It was determined that a measure of the vacuum was not sufficiently sensitive, and a research effort was undertaken to select an on-line monitoring device. In this effort, three promising methods were reviewed. The use of quadrupole mass spectrometer was recommended and an on-line device was designed for use in a Sodium Process Demonstration (SPD) Plant.

Investigation of Manganese Dioxide as an Improved Solid Desiccant (open access)

Investigation of Manganese Dioxide as an Improved Solid Desiccant

This report describes the preparation of a series of manganese oxides and an analysis of their sorptive, structural, and surface characteristics as low-energetic desiccants for passive dehumidification and active desiccant cooling systems. A cusped Type III isotherm for the adsorption of water is reported for the first time. The data are interpreted as evidence of a first-order phase change from a two-dimensional gas to a liquid film in the first reversibly adsorbed layer. It appears that the water adsorption characteristics of MnO2 compared to standard desiccants which exhibit Type II isotherms are due at least in part to differences in the physical topography and electronic properties of the desiccant substrates: MnO2 is a p-type semiconductor with essentially-flat, monoenergetic surface structures, while standard desiccants like silica gel are electronic insulators with irregular, heteroenergetic surfaces.

Elastic-Plastic Constitutive Modeling of Concrete (open access)

Elastic-Plastic Constitutive Modeling of Concrete

The need to understand concrete behavior under high temperatures in the nuclear industry has become rather acute. For this purpose, a constitutive model of concrete especially developed for this severe environment is indispensable. This report reviews the presently available constitutive models of concrete at standard-temperature conditions and considers their advantages and drawbacks. A rather simple but effective approach is selected to treat concrete behavior at high temperatures. Special emphasis is devoted to the modeling of concrete up to and including failure. The derived constitutive model is checked with biaxial and triaxial benchmark experimental results. Very good agreement is obtained.

The Optical Properties and Complex Dielectric Function of Metallic Aluminum from 0. 04 to 10⁴ eV (open access)

The Optical Properties and Complex Dielectric Function of Metallic Aluminum from 0. 04 to 10⁴ eV

Measurements of the optical properties of metallic aluminum are reviewed and available data are analyzed to obtain the bulk values of the optical constants and the complex dielectric function from 0.04 eV to 10 keV. The intra- and interband contributions to the dielectric function are discussed briefly, and recently proposed values for the Drude parameters describing the intraband absorption are critically considered. Factors influencing experimental measurements are discussed with emphasis on sample properties such as surface oxide layers, bulk inclusion of gases, surface roughness, and degree of crystallinity. The results of recent optical measurements are tabulated, along with recommended values of the optical properties resulting from a self-consistent Kramers-Kronig analysis of reflectance, transmission, and electron-energy-loss studies. The tabular data include the complex dielectric function, the complex index of refraction, and the reflectance and phase shift for normal incidence on a smooth, oxide-free surface. Detailed tabulations are given for the infrared, visible, and ultraviolet regions of the spectrum.

Proceedings of the Workshop on the Interface Between Radiation Chemistry and Radiation Physics; Held at Argonne National Laboratory, September 9-10, 1982 (open access)

Proceedings of the Workshop on the Interface Between Radiation Chemistry and Radiation Physics; Held at Argonne National Laboratory, September 9-10, 1982

This conference evolved out of an idea that originated Department of Energy contractor's meeting in Gettysburg to have a conference devoted to topics of interest to both radiation chemists and physicists in radiation research. Radiation chemists tend to operate in a time domain where chemical reactions can be observed and to deduce values from that data. Meanwhile, physicists naturally focus considerable attention on initial energy deposition events and perform calculations which should predict the same initial yields. Contributed papers and remarks have been grouped according to broad subjects.

The DIF3D Nodal Neutronics Option for Two- and Three-dimensional Diffusion Theory Calculations in Hexagonal Geometry (open access)

The DIF3D Nodal Neutronics Option for Two- and Three-dimensional Diffusion Theory Calculations in Hexagonal Geometry

A nodal method is developed for the solution of the neutron-diffusion equation in two- and three-dimensional hexagonal geometries. The nodal scheme has been incorporated as an option in the finite-difference diffusion-theory code DIF3D, and is intended for use in the analysis of current LMFBR designs. The nodal equations are derived using higher-order polynomial approximations to the spatial dependence of the flux within the hexagonal-z node. The final equations, which are cast in the form of inhomogeneous response-matrix equations for each energy group, involved spatial moments of the node-interior flux distribution plus surface-averaged partial currents across the faces of the node. These equations are solved using a conventional fission-source iteration accelerated by coarse-mesh rebalance and asymptotic source extrapolation. This report describes the mathematical development and numerical solution of the nodal equations, as well as the use of the nodal option and details concerning its programming structure. This latter information is intended to supplement the information provided in the separate documentation of the DIF3D code.

A User's Guide for the REBUS-3 Fuel Cycle Analysis Capability (open access)

A User's Guide for the REBUS-3 Fuel Cycle Analysis Capability

REBUS-3 is a system of programs designed for the fuel-cycle analysis of fast reactors. This new capability is an extension and refinement of the REBUS-3 code system and complies with the standard code practices and interface dataset specifications of the Committee on Computer Code Coordination (CCCC). The new code is hence divorced from the earlier ARC System. In addition, the coding has been designed to enhance code exportability. >Major new capabilities not available in the REBUS-2 code system include a search on burn cycle time to achieve a specified value for the multiplication constant at the end of the burn step; a general non-repetitive fuel-management capability including temporary out-of-core fuel storage, loading of fresh fuel, and subsequent retrieval and reloading of fuel; significantly expanded user input checking; expanded output edits; provision of prestored burnup chains to simplify user input; option of fixed-or free-field BCD input formats; and, choice of finite difference, nodal or spatial flux-synthesis neutronics in one-, two-, or three-dimensions.
