The purpose of this study was to develop the air emission projections for the maintenance operation to dissolve and flush out the scale material inside the F-Canyon Waste Header No.2. The chemical agent used for the dissolution is a concentrated nitric acid solution, so the pollutant of concern is the nitric acid vapor. Under the very conservative operating scenarios considered in this study, it was determined that the highest possible rate of nitric acid emission during the acid flush would be 0.048 lb. per hr. It turns out that this worst-case air emission projection is just below the current exemption limit of 0.05 lb. per hr. for permit applications.

We calculate the atmospheric structure of an accretion disk around a Kerr black hole and obtain its X-ray spectrum, which exhibits prominent atomic transitions under certain circumstances. The gravitational and Doppler (red)shifts of the C V, C VI, O VII, O VIII, and Fe I-XXVI emission lines are observable in active galaxies. We quantify the line emissivities as a function of radius, to identify the effects of atmospheric structure, and to determine the usefulness of these lines for probing the disk energetics. The line emissivities do not always scale linearly with the incident radiative energy, as in the case of Fe XXV and Fe XXVI. Our model incorporates photoionization and thermal balance for the plasma, the hydrostatic approximation perpendicular to the plane of the disk, and general relativistic tidal forces. We include radiative recombination rates, fluorescence yields, Compton scattering, and photoelectric opacities for the most abundant elements.

The Material Control and Accountability (MC and A) Group has developed an electronic scan system to acknowledge issuance and returns of Tamper Indicating Device (TID) seals. Important MC and A features of the system are: 1. The system requires the issuer identification and the identification of applicators to be entered, thereby ensuring that at least two qualified issuers and applicators possess the seals. Also, Operations is prompted to ensure the Two Person Rule is met during issuance and application of the seals. 2. All input is date and time stamped to ease resolution of anomalies. 3. The system requires all information to be input before allowing the user to logoff, thereby eliminating the problem of incomplete information in the records. 4. The input is immediately available to FBL MC and A personnel outside the facility who then know to expect completed procedures and forms regarding these transactions. The paper will describe the application of these features in routine operations as well as the development effort and final configuration of the system.

Researchers at the Savannah River Technology Center (SRTC) successfully demonstrated the Caustic-Side Solvent Extraction (CSSX) process flow sheet using a 33-stage, 2-cm centrifugal contactor apparatus in two 24-hour tests using actual high level waste. Previously, we demonstrated the solvent extraction process with actual SRS HLW supernatant solution using a non-optimized solvent formulation. Following that test, the solvent system was optimized to enhance extractant solubility in the diluent by increasing the modifier concentration. We now report results of two tests with the new and optimized solvent.

We present deep Chandra and XMM-Newton observations of the galaxy cluster RDCS1252.9-2927, which was selected from the ROSAT Deep Cluster Survey (RDCS) and confirmed by extensive spectroscopy with the VLT at redshift z = 1.237. With the Chandra data, the X-ray emission from the intra-cluster medium is well resolved and traced out to 500 kpc, thus allowing a measurement of the physical properties of the gas with unprecedented accuracy at this redshift. We detect a clear 6.7 keV Iron K line in the Chandra spectrum providing a redshift within 1% of the spectroscopic one. By augmenting our spectroscopic analysis with the XMM-Newton data (MOS detectors only), we significantly narrow down the 1{sigma} error bar to 10% for the temperature and 30% for the metallicity, with best fit values kT = 6.0{sup +0.7}{sub -0.5} keV, Z = 0.36{sup +0.12}{sup -0.10}Z{sub {circle_dot}}. In the likely hypothesis of hydrostatic equilibrium, we measure a total mass of M{sub 500} = (1.9{+-}0.3)10{sup 14}h{sup -1}{sub 70} M{sub {circle_dot}} within R{sub {Delta}=500} {approx} 536 kpc. Overall, these observations imply that RDCS1252.9-2927 is the most X-ray luminous and likely the most massive bona-fide cluster discovered to date at z > 1. When combined with current samples of distant …

This report is designed to fill the need for a simple tabulation of legislative workload. It provides the numbers of bills and joint resolutions introduced, and the numbers of public and private laws enacted, from the 80' Congress through the 108th Congress, first session (1947-2003).

The redshift distribution of well-defined samples of distant early-type galaxies offers a means to test the predictions of monolithic and hierarchical galaxy formation scenarios. NICMOS maps of the entire Hubble Deep Field North in the F110W and F160W filters, when combined with the available WFPC2 data, allow us to calculate photometric redshifts and determine the morphological appearance of galaxies at rest-frame optical wavelengths out to z {approx} 2.5. Here we report results for two subsamples of early-type galaxies, defined primarily by their morphologies in the F160W band, which were selected from the NICMOS data down to H{sub 160AB} < 24.0. A primary subsample is defined as the 34 galaxies with early-type galaxy morphologies and early-type galaxy spectral energy distributions. The secondary subsample is defined as those 42 objects which have early-type galaxy morphologies with non-early type galaxy spectral energy distributions. The observed redshift distributions of our two early-type samples do not match that predicted by a monolithic collapse model, which shows an overabundance at z > 1.5. A (V/V{sub max}) test confirms this result. When the effects of passive luminosity evolution are included in the calculation, the mean value of Vmax for the primary sample is 0.22 {+-} 0.05, and …

Testimony issued by the General Accounting Office with an abstract that begins "GAO is required to audit the consolidated financial statements of the U.S. government. Proper accounting and reporting practices are essential in the public sector. The U.S. government is the largest, most diverse, most complex, and arguably the most important entity on earth today. Its services--homeland security, national defense, Social Security, mail delivery, and food inspection, to name a few--directly affect the well-being of almost every American. But sound decisions on the future direction of vital federal government programs and policies are made more difficult without timely, accurate, and useful financial and performance information. Until the problems discussed in GAO's audit report on the U.S. government's consolidated financial statements are adequately addressed, they will continue to (1) hamper the federal government's ability to accurately report a significant portion of its assets, liabilities, and costs; (2) affect the federal government's ability to accurately measure the full cost as well as the financial and nonfinancial performance of certain programs while effectively managing related operations; and (3) significantly impair the federal government's ability to adequately safeguard certain significant assets and properly record various transactions."

This report provides a fact sheet about the Gasoline Excise Tax - Historical Revenues. The gas tax was regarded as a user tax where the federal government has imposed a gasoline excise tax with the passage of the revenue act in 1932.

This Geotechnical Analysis Report (GAR) presents and interprets the geotechnical data from the underground excavations at the Waste Isolation Pilot Plant (WIPP). The data, which are obtained as part of a regular monitoring program, are used to characterize conditions, to compare actual performance to the design assumptions, and to evaluate and forecast the performance of the underground excavations.

Testimony issued by the General Accounting Office with an abstract that begins "The Environmental Protection Agency (EPA) has long faced problems managing its grants, which constitute over one-half of the agency's annual budget, or about $4 billion. EPA uses grants to implement its programs to protect human health and the environment and awards grants to thousands of recipients, including state and local governments, tribes, universities, and nonprofit organizations. EPA's ability to efficiently and effectively accomplish its mission largely depends on how well it manages its grants resources. This testimony, based on GAO's August 2003 report Grants Management: EPA Needs to Strengthen Efforts to Address Persistent Challenges, GAO-03-846, focuses on the (1) major challenges EPA faces in managing its grants and how it has addressed these challenges in the past, and (2) extent to which EPA's recently issued policies and grants management plan address these challenges."

A letter report issued by the General Accounting Office with an abstract that begins "In our 2003 performance and accountability report on the Department of Housing and Urban Development (HUD), we continued to identify HUD's single-family (SF) mortgage insurance program as highrisk --an area we have found to be at high risk for fraud, waste, abuse, and mismanagement. Also, for years, GAO and HUD's Office of Inspector General (OIG) have reported weaknesses in HUD's contract administration and monitoring for both SF and multifamily (MF) programs. Given these known risks and the millions of dollars in disbursements made by the agency each year, GAO was asked to review payments related to the single-family property program and determine whether (1) internal controls provide reasonable assurance that improper payments will not be made or will be detected in the normal course of business and (2) payments are properly supported as a valid use of government funds. We also assessed HUD's monitoring of a major multifamily project with a state housing agency."

The development of a viable hydrogen storage system is one of the key challenges that must be met prior to the establishment of a true hydrogen economy. Current hydrogen storage options, such as compressed gas and liquid hydrogen, fall short of meeting vehicle manufacturers' goals for safe and efficient energy storage. The most viable long-term alternative to these options is solid-state storage, which has been proven both safe and efficient. The Savannah River Technology Center (SRTC), with over 50 years of hydrogen storage expertise and over 25 years of expertise in solid-state storage, has assembled a world-class team to meet this key challenge. The SRTC team is comprised of distinguished scientists and engineers from national laboratories, leading universities, and major corporate research centers that are actively performing research in hydrogen storage on complex hydrides. Their collective expertise in materials development combined with fundamental science and systems engineering, will provide the synergy to meet the hydrogen storage goals. The team's goal is to develop a hydrogen storage system that meets the 2010 U.S. DOE targets, which includes a system with greater than 6 wt per cent hydrogen.

Growing interest and exploration dollars within the geothermal sector have paved the way for increasingly sophisticated suites of geophysical and geochemical tools and methodologies. The efforts to characterize and assess known geothermal fields and find new, previously unknown resources has been aided by the advent of higher spatial resolution airborne geophysics (e.g. aeromagnetics), development of new seismic processing techniques, and the genesis of modern multi-dimensional fluid flow and structural modeling algorithms, just to name a few. One of the newest techniques on the scene, is hyperspectral imaging. Really an optical analytical geochemical tool, hyperspectral imagers (or imaging spectrometers as they are also called), are generally flown at medium to high altitudes aboard mid-sized aircraft and much in the same way more familiar geophysics are flown. The hyperspectral data records a continuous spatial record of the earth's surface, as well as measuring a continuous spectral record of reflected sunlight or emitted thermal radiation. This high fidelity, uninterrupted spatial and spectral record allows for accurate material distribution mapping and quantitative identification at the pixel to sub-pixel level. In volcanic/geothermal regions, this capability translates to synoptic, high spatial resolution, large-area mineral maps generated at time scales conducive to both the faster pace of …

A letter report issued by the General Accounting Office with an abstract that begins "Department of Defense (DOD) contractors perform numerous services that require access to classified information. With access comes the possibility of compromise, particularly as foreign entities increasingly seek U.S. military technologies. To ensure the protection of classified information, the National Industrial Security Program (NISP) establishes requirements that contractors must meet. In administering the NISP for DOD and 24 other government agencies, DOD's Defense Security Service (DSS) monitors whether 11,000- plus contractor facilities' security programs meet NISP requirements. In response to a Senate report accompanying the National Defense Authorization Act for Fiscal Year 2004, GAO assessed DSS's oversight and examined DSS's actions after possible compromises of classified information."

Testimony issued by the General Accounting Office with an abstract that begins "The federal government spends billions of dollars annually on information technology (IT) investments that are critical to the effective implementation of major government programs. To help agencies effectively manage their substantial IT investments, the Congress has established a statutory framework of requirements and roles and responsibilities relating to information and technology management, that addresses, for example, (1) IT strategic planning/performance measurement (which defines what an organization seeks to accomplish, identifies the strategies it will use to achieve desired results, and then determines how well it is succeeding in reaching resultsoriented goals and achieving objectives) and (2) IT investment management (which involves selecting, controlling, and evaluating investments). GAO was asked to summarize its January 2004 report on IT strategic planning/performance measurement and investment management (Information Technology Management: Governmentwide Strategic Planning, Performance Measurement, and Investment Management Can Be Further Improved, GAO-04-49, January 12, 2004) and to discuss how agencies can improve their performance in these areas."

The objective of the Lawrence Livermore National Laboratory (LLNL) Inertial Confinement Fusion (ICF) program is to demonstrate the scientific feasibility of ICF for military applications (to develop and utilize the capability to study nuclear weapons physics in support of the weapons program) and for energy-directed uses in the civilian sector. The demonstration of scientific feasibility for both military and civilian objectives will require achieving gains on the order of 10 to 100 in fusion microexplosions. Our major near-term milestones include the attainment of high compression, one-hundred to one-thousand times (100 to 1000X) liquid D-T density in the thermonuclear fuel and ignition of thermonuclear burn. In 1979, our laser fusion experiments and analysis programs focused on two important areas related to achieving this goal: conducting x-ray-driven implosions of a variety of D-T-filled fuel capsule's to unprecedented high densities ({approx}> 50X liquid D-T density) and the determination of the scaling of hot electrons and thermal radiation in hohlraums.

This report describes the activities related to siting and installation of the multi-cylinder engine for homogeneous charge compression ignition (HCCI) engine operation as part of the Advanced Reciprocating Internal Combustion Engine (ARICE) program. Site selection involved locating a site that was appropriate for engine operation related to the project goals. A key part of the site selection was the choice of the engine generator set. The criteria used for selection of the site and engine generator set are discussed in relation to satisfying the goals of this project. This report describes the work on this task as part of the larger ARICE HCCI engine development project.

The production of large fluxes of pions and muons using high-energy, high-intensity proton pulses impinging on solid or liquid targets presents unique problems which have not yet been entirely solved. We investigate the possibilities of using solid targets by choosing a metal of either extremely low thermal expansion coefficient 1 or exceptionally high mechanical strength. Candidates are respectively Super-Invar and Vascomax 350 or Inconel 718. Moving targets in the form of chains or cables would be required for cooling purposes. These materials seem easily capable of surviving the beam pulses required for the largest beam power contemplated. Questions regarding radiation damage effects are being investigated.

In this analysis the proposed 10MW window design is free of multipacting on the ceramic surface for the full power range, both in the traveling wave and full reflection mode. Near 7MW and 8MW in the traveling wave mode, multipacting might show up on the outer conductor of the matching section. These multipacting barriers are however very soft and are expected to be easily eliminated by regular RF processing. The multipacting analysis can identify early design problems while it is unable to provide certainty in design success and testing of window designs is the only certain measure of freedom from multipacting.

We report measurements of the line polarization of Ne-like and F-like of iron n=3 to n=2 transitions in the x-ray region. We used the ''two-crystal technique'' developed in previous polarization measurements in our laboratory. Preliminary results from our measurements are presented together with the theoretical calculations using the Flexible Atomic Code (FAC). Our calculations show that contributions from cascades play an important role in the polarization calculations of most of the transitions. The uncertainties and difficulties of our experiments are also discussed.

Testimony issued by the General Accounting Office with an abstract that begins "As health insurance premiums have risen at double-digit rates in recent years, employers and individuals who have sought to purchase more affordable coverage have fallen prey to certain entities that may offer attractively priced premiums but do not fulfill the expectations of those buying health insurance. These unauthorized entities--also known as bogus entities or scams--may not meet the financial and benefit requirements typically associated with health insurance products or other arrangements that are authorized, licensed, and regulated by the states. This testimony is based on GAO's recent report Private Health Insurance: Employers and Individuals Are Vulnerable to Unauthorized or Bogus Entities Selling Coverage, GAO-04-312 (Feb. 27, 2004). In this testimony, GAO was asked to identify the number of entities that operated from 2000 through 2002 and the number of employers and policyholders affected, approaches and characteristics of these entities' operations, and the actions federal and state governments took against these entities. GAO analyzed information obtained from the Department of Labor (DOL) and from a survey of insurance departments in the states; interviewed officials at DOL and at insurance departments in Colorado, Florida, Georgia, and Texas; and examined the …

We discuss particle tracking simulations in a storage ring with lithium lens inserts designed for the six-dimensional phase space cooling of muons by the ionization cooling. The ring design contains one or more lithium lens absorbers for transverse cooling that transmit the beam with very small beta-function values, in addition to liquid-hydrogen wedge-shaped absorbers in dispersive locations for longitudinal cooling. Such a ring could comprise the final component of a cooling system for use in a muon collider. The beam matching between dipole-quadrupole lattices and the lithium lenses is of particular interest.
