Effects of assembly local power distribution on storage rack criticality

Description: Fuel storage rack criticality calculations have been performed for a set of 8 x 8 BWR k/sub infinity/-equivalent fuel bundles. The results of these calculations indicate that the storage rack multiplication factor is not determined solely by the k/sub infinity/'s of the individual fuel assemblies, but is also sensitive to the local power, and underlying enrichment, burnable poison, water hole and burnup distributions. Furthermore, in order to insure a true conservative upper bound on the storage rack multiplication factor, reference assemblies with the most centrally peaked power distributions should be selected. 2 refs., 1 fig.

GeoProducts WEN-2 well, Wendel-Amedee, California

Description: The GeoProducts WEN-2 well, drilled 2200 feet northwest of Wendel Hot Springs in Lassen County, California, penetrated 4330 feet (1320 meters) of Tertiary basalt flows and volcanoclastics. Production of 251/sup 0/F (122/sup 0/C) thermal fluids comes either from a fault or from intergranular permeability in a 570-foot thick quartzite conglomerate channel overlying the granitic basement rocks at a depth of 4900 feet. The chemistry, temperature and hydrostatic head of the resource in WEN-2 are very similar to that of WEN-1 to the northeast. Unknown faults in the granitic basement rocks, other than the Wendel fault, may be important channelways for the geothermal system. 4 refs., 3 figs.

Flux-line pinning by the grain boundary in niobium bicrystals

Description: Flux-line pinning by the grain boundary in niobium bicrystals was investigated by making four-terminal measurements of the critical current and neutron diffraction measurements of the flux-line bending. The elementary pinning interaction is estimated from the critical current data by using an approximate theory of the current distribution on the grain boundary. The data reported here are mainly for a sample in which the applied magnetic field is parallel to the (111) and the (001) crystal directions in the two grains when it is in the plane of the boundary and perpendicular to the current direction. Evidence is seen of grain boundary faceting and of a flux-flow rectification effect that peaks as a function of temperature below 3/sup 0/K. The scale of the grain-boundary pinning is consistent with the quasiparticle-scattering theory.

Progress in radiation immune thermionic integrated circuits

Description: This report describes the results of a program directed at evaluating the thermionic integrated circuit (TIC) technology for applicability to military systems. Previous programs under the sponsorship of the Department of Energy, Office of Basic Energy Sciences, have developed an initial TIC technology base and demonstrated operation in high-temperature and high-radiation environments. The program described in this report has two parts: (1) a technical portion in which experiments and analyses were conducted to refine perceptions of near-term as well as ultimate performance levels of the TIC technology and (2) an applications portion in which the technical conclusions were to be evaluated against potential military applications. This report draws several conclusions that strongly suggest that (1) useful radiation-hard/high-temperature operable integrated circuits can be developed using the TIC technology; (2) because of their ability to survive and operate in hostile environments, a variety of potential military applications have been projected for this technology; and (3) based on the above two conclusions, an aggressive TIC development program should be initiated to provide the designers of future systems with integrated circuits and devices with the unique features of the TICs.

Examination of alternative catalysts for biomass direct liquefaction

Description: We have now completed a survey study of several water-soluble salts of transition metals that are deemed likely to have utility as catalysts for direct biomass liquefaction in a carbon monoxide steam process. Certain salts of molybdenum and nickel are the most effective catalysts, and are the only species for which some catalytic activity independent of the ligand can be shown. The most effective forms of the nickel and molybdenum are cyanide and oxyanion complexes. 30 refs., 5 figs., 4 tabs.

Accessibility of second regions of stability in tokamaks

Description: Second regions of stability to the ideal ballooning modes have been shown to exist in large-aspect-ratio circular and small-aspect-ratio bean-shaped tokamaks. We report on the existence of these second stability regions in finite-aspect-ratio dee-shaped tokamaks. We also report on the discovery of a second-stable region with respect to the n = 1 external kink mode in a bean-shaped plasma. The role of the shear and current profile in determining these regions of parameter space are discussed. 13 refs., 6 figs.

Hanna, Wyoming underground coal gasification data base. Volume 6. Hanna IVA and IVB field test research report

Description: This report is part of a seven-volume series on the Hanna, Wyoming, underground coal gasification field tests. Volume 1 is a summary of the project and each of Volumes 2 through 6 describes a particular test. Volume 7 is a compilation of all the data for the tests in Volumes 2 through 6. The reports in this series include: The Hanna IV test was designed as the first underground coal gasification test using commercial well spacings of 100 and 150 feet between well pairs in a linear 3-well pattern. The test was initiated in late 1977 and completed in late 1979. This long duration was due to unfavorable geologic conditions (faulting) which could not be successfully overcome resulting in the test being split into Hanna IVA and Hanna IVB with about one year between the conduct of each. This report covers: (1) specific site selection and characteristics; (2) test objectives; (3) facility description; (4) pre-operation tests; (5) test operations summary; and (6) post-test activity. 5 refs., 19 figs., 13 tabs.

Optical models in the resolved resonance region

Description: Using modern time-of-flight facilities the resolved region can be extended upward to about 1 MeV for nuclei with A < 60 and for heavier nuclei near closed shells. A careful measurement both on and off resonances followed by an R-matrix analysis yields partial wave scattering functions which are easily energy averaged for comparison to those from an optical model. A comparison of average scattering functions of opposite parities can provide information on surface effects because the wave functions for different parities are out of phase at the surface. Thus, a unique supplement is made to the information that can be obtained from other types of measurements for both the bound region and higher energies. 16 refs., 9 figs., 1 tab.

Heavy ion beam transport through liquid lithium first wall ICF reactor cavities. [R]

Description: This analysis addresses the critical issue of the final transport of a heavy ion beam in an inertial confinement fusion reactor. The beam must traverse the reaction chamber from the final focusing lens to the target without being disrupted. This requirement has a strong impact on the reactor design. It is essential to the development of ICF fusion reactor technology, that the restrictions placed on the reactor engineering parameters by final beam transport consideration be understood early on.

MINTEQ2 geochemical code: provisionary organic data base

Description: Organic components in aqueous radioactive chemical sources, surface waters, and ground waters could substantially alter the mobility of radioactive and other important nonradioactive elements released from a defense waste disposal system. It is therefore important to be able to predict, as accurately as possible, the effects of selected organic components on the solubilities of radionuclides and important nonradioactive elements. The geochemical code MINTEQ2 can be used to assess solubilities provided that appropriate thermochemical data for organic and inorganic aqueous species and solids are available for its use. The code accepts an assemblage of gaseous and solid phases in contact with an aqueous phase and calculates the thermochemical equilibrium between these phases. Unlike typical hydrologic flow and transport codes where the data base is entirely site specific (i.e., parameters particular to the specific site), MINTEQ2 requires an additional generic thermochemical data base. This report discusses the addition of provisionary organic reactions and associated equilibrium constants to the generic data base that can be used by MINTEQ2 in scoping calculations or preliminary performance assessments.

Impacts of alternative residential energy standards - Rural Housing Amendments Study, Phase 1

Description: This report has examined the role of manufactured housing in the housing market, the energy impacts of three manufactured housing standards and three site-built standards in 13 cities, and the economic impacts of those standards in 6 cities. The three standards applied to manufactured housing are the HUD Title VI standard (Manufactured Housing Construction and Safety Standards, or MHCSS), the Hud Title II-E standard, and the existing FmHA Title V standard. Those applied to site-built homes are the HUD Minimum Property Standards (MPS), the ASHRAE 90A-80 standard, and the FmHA Title V standard. Based on energy consumption alone, these analyses show that the FmHA Title V standard is the most stringent standard for both housing types (a single-section menufactured home and a single-story detached ''ranch house''). The HUD Title VI standard is the least stringent for manufactured homes, while the HUD Minimum Property Standards are the least stringent for site-built homes. Cost-effectiveness comparisons required by the Act were made for the two prototypical homes. Results of this preliminary economic analysis indicate that none of the site-built standards reflect minimum life-cycle cost as a basic criterion of their development. For manufactured homes, both the FmHA standard and the HUD Title II-E standard reduce life-cycle cost and effect positive first-year cash flows in all cities analyzed when electric resistance heating is assumed. When natural gas heating is used, both standards pass the life-cycle cost test in all cities, but the FmHA standard fails the cash flow test in all but one city. However, in the worst case, net monthly expenditures in the first year are increased by less than $9.

Aluminum and boron phosphates as possible proton conductors

Description: The chemical stability and conductivity of boron and aluminum phosphates in steam are reported for P/B and P/A1 atomic ratios greater than unity at temperatures from 100/sup 0/ to 280/sup 0/C and steam pressures to 5 atmospheres. Al(PO/sub 3/)/sub 3/ and H/sub 2/ A1P/sub 3/O/sub 10/ undergo the reactions Al (PO/sub 3/)/sub 3/ + H/sub 2/) in equilibrium H/sub 2/AlP/sub 3/O/sub 10/ and H/sub 2/AlP/sub 3/O/sub 10/ ..-->.. AlPO/sub 4/ + H/sub 2/O.P/sub 2/O/sub 5/(g). At 280/sup 0/C and a steam pressure of 5 atmospheres gauge the product is mixture of AlPO/sub 4/ and H/sub 2/ALP/sub 3/O/sub 10/, while the conductivity of this solid is in the range of 10/sup -2/ ohm/sup -1/ cm/sup -1/. The boron phosphates lose material and exhibit poor conductivity under similar conditions due to the instability of the BPO/sub 4/ phase as a result of the reaction 2BPO/sub 4/ + 6 H/sub 2/O ..-->.. B/sub 2/O/sub 3/.3H/sub 2/O(g) + P/sub 2/O/sub 5/. 3H/sub 2/O(g). As a result of dehydration or hydrolytic reactions an increase in water vapor pressure does not always lead to increased conductivity even at higher temperature.

Design and fabrication of a Transverse Field Focussing (TFF) 180 keV negative ion accelerator

Description: The 180 keV Transverse Field Focussing (TFF) negative ion accelerator described is the final component of a negative ion based neutral beam acceleration system which is being developed as proof-of-principle demonstration of a radiation hardened neutral beamline. The 180 keV beamline consists of: a surface conversion negative ion source, a 80 keV pre-accelerator, a TFF pumping, matching, and transport section, and the 180 keV TFF accelerator presented. This beamline is expected to provide 1 A of H/sup -/ at 180 keV. In the design of the accelerator, particular importance was given to the rigidity of the accelerator electrode mounting structures and to the electrical isolation of the electrodes along with their related cooling lines. An optical alignment scheme was developed to assemble and to insure precision alignment of the electrodes. (LEW)

Spatially-resolved investigation of transport in semiconductors: a photothermal deflection approach

Description: The unique ability of photothermal deflection spectroscopy to probe the local index of refraction of matter is exploited to investigate, in a spatially-resolved manner, thermal and electronic transport in semiconductors. An added advantage of this approach is that it is contactless; hence, it obviates the classical problems associated with electrodes and contacts. The basic premise of the technique is the use of the heat associated with non-radiative processes (e.g., recombination of carriers) to deflect a focussed laser probe beam (sub-gap energy) propagating through the semiconductor. The deflection of the probe beam is caused by a change in the refractive index of the sample which is in turn governed by carrier diffusion and recombination.

Project Surveillance and Maintenance Plan. [UMTRA Project]

Description: The Project Surveillance and Maintenance Plan (PSMP) describes the procedures that will be used by the US Department of Energy (DOE), or other agency as designated by the President to verify that inactive uranium tailings disposal facilities remain in compliance with licensing requirements and US Environmental Protection Agency (EPA) standards for remedial actions. The PSMP will be used as a guide for the development of individual Site Surveillance and Maintenance Plans (part of a license application) for each of the UMTRA Project sites. The PSMP is not intended to provide minimum requirements but rather to provide guidance in the selection of surveillance measures. For example, the plan acknowledges that ground-water monitoring may or may not be required and provides the (guidance) to make this decision. The Site Surveillance and Maintenance Plans (SSMPs) will form the basis for the licensing of the long-term surveillance and maintenance of each UMTRA Project site by the NRC. Therefore, the PSMP is a key milestone in the licensing process of all UMTRA Project sites. The Project Licensing Plan (DOE, 1984a) describes the licensing process. 11 refs., 22 figs., 8 tabs.
