235U and TRU Holdup Measurements on the 321-M Sawbenches

Description: The Analytical Development Section of Savannah River Technology Center (SRTC) was requested by the Facilities Disposition Projects (FDP) to determine the holdup of enriched uranium in the 321-M facility as part of an overall deactivation project of the facility. The 321-M facility was used to fabricate enriched uranium fuel assemblies, lithium-aluminum target tubes, neptunium assemblies, and miscellaneous components for the production reactors. The results of the holdup assays are essential for… more

Continuous Material Balance Reconciliation for a Modern Plutonium Processing Facility

Description: This paper describes a safeguards approach that can be deployed at any modern plutonium processing facility to increase the level of safeguards assurance and significantly reduce the impact of safeguards on process operations. One of the most perplexing problems facing the designers of plutonium processing facilities is the constraint placed upon the limit of error of the inventory difference (LEID). The current DOE manual constrains the LEID for Category I and II material balance areas to 2 pe… more

Determination of the Tissue Distribution and Excretion by Accelerator Mass Spectrometry of the Nonadecapeptide 14C-Moli1901 in Beagle dogs after Intratracheal Instillation

Description: Administration of {sup 14}C-Moli1901 (duramycin, 2622U90), a 19 amino acid polycyclic peptide by intratracheal instillation (approximately 100 {micro}g) into the left cranial lobe of the lung of beagle dogs resulted in retention of 64% of the dose in the left cranial lobe for up to 28 days. In this study, we used accelerator mass spectrometry (AMS) to quantify Moli901 following administration of only 0.045 {micro}Ci of {sup 14}C-Moli901 per dog. Limits of quantitation of AMS were 0.03 (urine) t… more

Drug Control: U.S. Nonmilitary Assistance to Colombia Is Beginning to Show Intended Results, but Programs Are Not Readily Sustainable

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since 2000, the U.S. government has provided a total of $3.3 billion to Colombia, making it the fifth largest recipient of U.S. assistance. Part of this funding has gone toward nonmilitary assistance to Colombia, including programs to (1) promote legitimate economic alternatives to coca and opium poppy; (2) assist Colombia's vulnerable groups, particularly internally displaced persons; and (3) strengthe… more

FAA Budget Policies and Practices

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "In recent years, Congress has raised concerns about cost growth in the Federal Aviation Administration's (FAA) operating budget. Appropriators noted several expenses in FAA's fiscal year 2004 facilities and equipment (F&E) account budget submission that appeared to be ongoing operating expenses. The House and Senate appropriations subcommittee reports on FAA's fiscal year 2004 budget submission highlight… more

Measurements of Transverse Energy Distributions in Au+Au Collisions at {radical}s{sub NN} = 200 GeV

Description: Transverse energy (E{sub T}) distributions have been measured for Au+Au collisions at {radical}s{sub NN} = 200 GeV by the STAR collaboration at RHIC. E{sub T} is constructed from its hadronic and electromagnetic components, which have been measured separately. E{sub T} production for the most central collisions is well described by several theoretical models whose common feature is large energy density achieved early in the fireball evolution. The magnitude and centrality dependence of E{sub T}… more

A Method for Analysing High Resolution, Time Domain, Streak Camera Calibration Data

Description: Many experiments that require a highly accurate continuous time history of photon emission incorporate streak cameras into their setup. Nonlinear recordings both in time and spatial displacement are inherent to streak camera measurements. These nonlinearities can be attributed to sweep rate electronics, curvature of the electron optics, the magnification, and resolution of the electron optics. These nonlinearities are systematic; it has been shown that a short pulse laser source, an air-spaced … more

Modeling of Diffusion of Plutonium in Other Metals and of Gaseous Species in Plutonium-Based Systems

Description: Establish standards for temperature conditions under which plutonium, uranium, or neptunium from nuclear wastes permeates steel, with which it is in contact, by diffusion processes. The primary focus is on plutonium because of the greater difficulties created by the peculiarities of face-centered-cubic-stabilized (delta) plutonium (the form used in the technology generating the waste).

Potential energy sputtering of EUVL materials

Description: Of the many candidates employed for understanding the erosion of critical Extreme Ultraviolet Lithography (EUVL) components, potential energy damage remains relatively uninvestigated. Unlike the familiar kinetic energy sputtering, which is a consequence of the momentum transferred by an ion to atoms in the target, potential energy sputtering occurs when an ion rapidly collects charge from the target as it neutralizes. Since the neutralization energy of a singly charged ion is typically on the o… more

Proposed Mission Concept for the Astrophysical Plasma-dynamic Explorer (APEX): An EUV High-Resolution Spectroscopic SMEX

Description: EUVE and the ROSAT WFC have left a tremendous legacy in astrophysics at EUV wavelengths. More recently, Chandra and XMM-Newton have demonstrated at X-ray wavelengths the power of high-resolution astronomical spectroscopy, which allows the identification of weak emission lines, the measurement of Doppler shifts and line profiles, and the detection of narrow absorption features. This leads to a complete understanding of the density, temperature, abundance, magnetic, and dynamic structure of astro… more

Rapid Qualitative Risk Assessment for Contaminant Leakage From Coal Seams During Underground Coal Gasification and CO2 Injection

Description: One of the major risks associated with underground coal gasification is contamination of local aquifers with a variety of toxic compounds. It is likely that the rate, volume, extent, and concentrations of contaminant plumes will depend on the local permeability field near the point of gasification. This field depends heavily on the geological history of stratigraphic deposition and the specifics of stratigraphic succession. Some coals are thick and isolated, whereas others are thinner and more … more

Social Security Administration: More Effort Needed to Assess Consistency of Disability Decisions

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Each year, about 2.5 million people file claims with the Social Security Administration (SSA) for disability benefits. If the claim is denied at the initial level, the claimant may appeal to the hearings level. The hearings level has allowed more than half of all appealed claims, an allowance rate that has raised concerns about the consistency of decisions made at the two levels. To help ensure consiste… more
