5-Volt and 4.6 V plateaus in LiMn₂O₄ thin films

Description: Additional plateaus with median voltages of {similar_to}4.6 V, and {similar_to}5 V have been observed on charging thin film lithium batteries with crystalline LiMn{sub 2}O{sub 4} cathodes to 5.3 V. Total charge extracted from the 4 V and the two additional plateaus corresponded to about 1Li/Mn{sub 2}O{sub 4}, but the distribution of capacity among the three plateaus varied from film to film. It is speculated that the additional plateaus result from formation of mixed spinel structures in which … more

60-day waste compatibility safety issue and final results for 244-TX DCRT, grab samples TX-95-1, TX-95-2, and TX-95-3

Description: Three grab samples (TX-95-1, TX-95-2, and TX-95-3) were taken from tank 241- TX-244 riser 8 on November 7, 1995 and received by the 222-S Laboratory on that same day. Samples TX-95-1 and TX-95-2 were designated as supernate liquids, and sample TX-95-3 was designated as a supernate/sludge. These samples were analyzed to support the waste compatibility safety program. Accuracy and precision criteria were met for all analyses. No notifications were required based on sample results.

1990 Activity report for 1986-1992

Description: As discussed in last year`s Activity Report, a fairly complete analysis of SPEAR problems was performed in concert with SLAC, and a major maintenance/improvement process was initiated in the spring of 1989. This run made it apparent that SPEAR will remain a very useful and impressive synchrotron radiation storage ring for at least a decade, given a steady maintenance and improvement program.

1995 Midnite Mine Radiation Survey

Description: Abstract: During the week of September 4, 1995, personnel from the U.S. Bureau of Mines conducted a Ra-226 survey at the Midnite Mine. One hundred thirty measurements were made on a rectangular grid with 150-m spacings. Concurrently, Shepherd Miller, Inc., took gross gamma readings in gR/h at the same grid points. In addition, the USBM collected 17 soil samples to be analyzed for radium, thorium, and potassium. The results of this survey are summarized in this report.

3DTOM, Three-Dimensional Geophysical Tomography

Description: Abstract: 3DTOM is a DOS-compatible computer program developed by the Mines U.S. Bureau of for three-dimensional tomographic imaging of the subsurface at mine sites. The program uses the simultaneous iterative reconstruction technique (SIRT) to invert travel- time data and produce maps of wave velocity, or to invert amplitude data and generate maps of wave attenuation coefficients. Either seismic (compressional and/or shear) or electromagnetic (e.g., radio or radar) wave data may be used. Ray t… more

Acceleration to collisions for the {mu}{sup +}-{mu}{sup {minus}} collider

Description: The authors discuss the problem of transforming muon beam bunches from a low-energy cooled state (E{sub {mu}} {approximately} 1 GeV) to short, high-energy bunches matched to high-energy collision conditions (E{sub {mu}} {approximately} 2 TeV). In this process the beam energy must increase by {approximately} three orders of magnitude, while the bunch length must be reduced by {approximately} two orders of magnitude (to {approximately} 3mm), while beam emittance dilution and beam losses, particul… more

Actinide partitioning studies using dihexyl-N,N-diethycarbamolymehtyl phosphonate and dissolved zirconium calcine

Description: A baseline flowsheet capable of partitioning the transuranic (TRU) elements from dissolved zirconium calcines has been developed. The goal of the TRU partitioning process is to remove the TRUs from solutions of dissolved zirconium calcines to below the 10 CFR 61.55 Class A waste limit of 10 nCi/g. Extraction, scrub, strip, and wash distribution coefficients for several elements, including the actinides, were measured in the laboratory by performing equal volume batch contacts. A solvent contain… more

Additional nuclear criticality safety calculations for small-diameter containers

Description: This report documents additional criticality safety analysis calculations for small diameter containers, which were originally documented in Reference 1. The results in Reference 1 indicated that some of the small diameter containers did not meet the criteria established for criticality safety at the Portsmouth facility (K{sub eff} +2{sigma}<.95) when modeled under various contingency assumptions of reflection and moderation. The calculations performed in this report reexamine those cases which… more

Advanced processing technology for high-efficiency, thin-film CuInSe₂ and CdTe solar cells. Final subcontract report, March 1, 1992--April 30, 1995

Description: This report describes work performed by the University of South Florida to develop a manufacturing-friendly fabrication process for CuInSe{sub 2} (CIS) solar cells. The process developed under this project uses conventional deposition processes and equipment, does not require stringent process control, and uses elemental Se as the selenium source. The authors believe it can be readily scaled up using off-the-shelf processing equipment and that it will meet the low manufacturing-cost objectives.… more

Advanced sulfur control concepts for hot gas desulfurization technology. Quarterly report, October--December 1995

Description: In the area of gas analysis, most of the attention during the past quarter was devoted to gaining an understanding of the operation of the Antek total sulfur analyzer, and making appropriate modifications in the unit. The primary problem is that the resistance of the capillary flow restrictor is not large enough, and the amount of sulfur which reaches the UV-analyzer results in the analyzer becoming saturated. We have added a N{sub 2} diluent flow downstream of the pyrotube tube which, we belie… more

Aging Assessment of Surge Protective Devices in Nuclear Power Plants

Description: An assessment was performed to determine the effects of aging on the performance and availability of surge protective devices (SPDs), used in electrical power and control systems in nuclear power plants. Although SPDs have not been classified as safety-related, they are risk-important because they can minimize the initiating event frequencies associated with loss of offsite power and reactor trips. Conversely, their failure due to age might cause some of those initiating events, e.g., through s… more

Alpha particle losses from Tokamak Fusion Test Reactor deuterium-tritium plasmas

Description: Because alpha particle losses can have a significant influence on tokamak reactor viability, the loss of deuterium-tritium alpha particles from the Tokamak Fusion Test Reactor (TFTR) has been measured under a wide range of conditions. In TFTR, first orbit loss and stochastic toroidal field ripple diffusion are always present. Other losses can arise due to magnetohydrodynamic instabilities or due to waves in the ion cyclotron range of frequencies. No alpha particle losses have yet been seen due … more
