Ballistic Experiments with Titanium and Aluminum Targets
During the course of the project we conducted two sets of fundamental experiments in penetration mechanics in the LLNL Terminal Ballistics Laboratory of the Physics Directorate. The first set of full-scale experiments was conducted with a 14.5mm air propelled launcher. The object of the experiments was to determine the ballistic limit speed of 6Al-4V-alloy titanium, low fineness ratio projectiles centrally impacting 2024-T3 alloy aluminum flat plates and the failure modes of the projectiles and the targets. The second set of one-third scale experiments was conducted with a 14.5mm powder launcher. The object of these experiments was to determine the ballistic limit speed of 6Al-4V alloy titanium high fineness ratio projectiles centrally impacting 6Al-4V alloy titanium flat plates and the failure modes of the projectiles and the target. We employed radiography to observe a projectile just before and after interaction with a target plate. Early on, we employed a non-damaging ''soft-catch'' technique to capture projectiles after they perforated targets. Once we realized that a projectile was not damaged during interaction with a target, we used a 4-inch thick 6061-T6-alloy aluminum witness block with a 6.0-inch x 6.0-inch cross-section to measure projectile residual penetration. We have recorded and tabulated below projectile impact …

The behavior of silicon and boron in the surface of corroded nuclear waste glasses : an EFTEM study.
Using electron energy-loss filtered transmission electron microscopy (EFTEM), we have observed the formation of silicon-rich zones on the corroded surface of a West Valley (WV6) glass. This layer is approximately 100-200 nm thick and is directly underneath a precipitated smectite clay layer. Under conventional (C)TEM illumination, this layer is invisible; indeed, more commonly used analytical techniques, such as x-ray energy dispersive spectroscopy (EDS), have failed to describe fully the localized changes in the boron and silicon contents across this region. Similar silicon-rich and boron-depleted zones were not found on corroded Savannah River Laboratory (SRL) borosilicate glasses, including SRL-EA and SRL-51, although they possessed similar-looking clay layers. This study demonstrates a new tool for examining the corroded surfaces of materials.

Decay rates of spherical and deformed proton emitters
Using Green's function techniques, the authors derive expressions for the width of a proton decaying state in spherical and deformed nuclei. The authors show that the proton decay widths calculated by the exact expressions of Maglione et al. are equivalent to the distorted wave expressions of Bugrov et al., and that of {angstrom} berg et al. in the spherical case.

The Excavation and Remediation of the Sandia National Laboratories Chemical Waste Landfill
The Chemical Waste Landfill (CWL) at Sandia National Laboratories/New Mexico (SNL/NM) is a 1.9-acre disposal site that was used for the disposal of chemical wastes generated by many of SNL/NM research laboratories from 1962 until 1985. These laboratories were primarily involved in the design, research and development of non-nuclear components of nuclear weapons and the waste generated by these labs included small quantities of a wide assortment of chemical products. A Resource Conservation and Recovery Act (RCRA) Closure Plan for the Chemical Waste Landfill was approved by the New Mexico Environment Department (NMED) in 1992. Subsequent site characterization activities identified the presence of significant amounts of chromium in the soil as far as 80 feet below ground surface (fbgs) and the delineation of a solvent plume in the vadose zone that extends to groundwater approximately 500 fbgs. Trichloroethylene (TCE) was detected in some groundwater samples at concentrations slightly above the drinking water limit of 5 parts per billion. In 1997 an active vapor extraction system reduced the size of the TCE vapor plume and for the last six quarterly sampling events groundwater samples have not detected TCE above the drinking water standard. A source term removal, being conducted as a …

Isospin-Forbidden B-Delayed Proton Emission
The effects of isospin-symmetry breaking on proton emission following {beta}-decay to the isobaric analog state are discussed in detail. Of particular importance is the mixing with a dense background of lower isospin states, whose properties are not well known. The possibility of observing T=4 states in even-even, N=Z nuclei, which is viable if the decay proceeds via isospin-forbidden particle emission, is also discussed.

Microbial genome program report: Optical approaches for physical mapping and sequence assembly of the Deinococcus radiodurans chromosome
Maps of genomic or cloned DNA are frequently constructed by analyzing the cleavage patterns produced by restriction enzymes. Restriction enzymes are remarkable reagents that faithfully cleave only at specific sequences of between 4 and 8 nucleotides, which vary according to the specific enzymes. Restriction enzymes are reliable, numerous, and easily obtainable and presently, there are approximately 250 different sequences represented among thousands of enzymes. Restriction maps characterize gene structure and even entire genomes. Furthermore, such maps provide a useful scaffold for the alignment and verification of sequence data. Restriction maps generated by computer and predicted from the sequence are aligned with the actual restriction map. Restriction enzyme action has traditionally been assayed by gel electrophoresis. This technique separates cleaved molecules on the basis of their nobilities under the influence of an applied electrical field, within a gel separation matrix (small fragments have a greater mobility than large ones). Although gel electrophoresis distinguishes different sized DNA fragments (known as a fingerprint), the original order of these fragments remains unknown. The subsequent task of determining the order of such fragments is a labor intensive task, especially when making restriction maps of whole genomes, and therefore despite its obvious utility to genome analysis, …

Ninth workshop on crystalline silicon solar cell materials and processes: Summary discussion sessions
This report is a summary of the panel discussions included with the Ninth Workshop on Crystalline Silicon Solar Cell Materials and Processes. The theme for the workshop was ``R and D Challenges and Opportunities in Si Photovoltaics.'' This theme was chosen because it appropriately reflects a host of challenges that the growing production of Si photovoltaics will be facing in the new millennium. The anticipated challenges will arise in developing strategies for cost reduction, increased production, higher throughput per manufacturing line, new sources of low-cost Si, and the introduction of new manufacturing processes for cell production. At the same time, technologies based on CdTe and CIS will come on line posing new competition. With these challenges come new opportunities for Si PV to wean itself from the microelectronics industry, to embark on a more aggressive program in thin-film Si solar cells, and to try new approaches to process monitoring.

A Preliminary Calculation of 235U (n,2n) 234U Cross Sections
Preliminary calculations of the total two-neutron emission cross section, {sup 235}U(n,2n) {sup 234}U and the partial two-neutron emission cross sections, {sup 235}U(n, 2n{gamma}) {sup 234}U, are presented. The {sup 235}U(n, 2n{gamma}) {sup 234}U cross sections describe the process of {gamma}-decays in the residual nucleus following the two-neutron emission and were calculated for several {gamma}-transitions between states of the ground-state band of the {sup 234}U nucleus. All three reaction mechanisms, namely, direct, pre-equilibrium and compound, were included. In addition, fission competition as well as {gamma}-cascade were considered in the compound component of the cross section calculations. A comparison with the relevant experimental data obtained from the GEANIE detector at the LANSCE/WNR facility in Los Alamos was also carried out.

Proposed Use of a Constructed Wetland for the Treatment of Metals in the S-04 Outfall of the Defense Waste Processing Facility at the Savannah River Site
The DWPF is part of an integrated waste treatment system at the SRS to treat wastes containing radioactive contaminants. In the early 1980s the DOE recognized that there would be significant safety and cost advantages associated with immobilizing the radioactive waste in a stable solid form. The Defense Waste Processing Facility was designed and constructed to accomplish this task.
