Department of Energy: Opportunities Exist to Improve Los Alamos' Equipment Purchasing Practices (open access)

Department of Energy: Opportunities Exist to Improve Los Alamos' Equipment Purchasing Practices

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Energy (DOE) received $13.2 million in supplemental funding to replace equipment lost at the Los Alamos National Laboratory in the May 2000 Cerro Grande fire. GAO reviewed the practices used by the contractor that runs the laboratory--the University of California (UC)--to determine whether it can benefit from modified purchasing practices. GAO found that UC can save money by (1) expanding its supply sources to include suppliers such as the General Services Administration and the Internet; (2) establishing mandatory maximum performance standards for computer purchases to avoid unjustified, costly, and unnecessary capabilities; and (3) increasing its use of a standard brand of computer and computer-related equipment to maximize volume discounts with selected suppliers."

Generic Degraded Congiguration Probability Analysis for DOE Codisposal Waste Package (open access)

Generic Degraded Congiguration Probability Analysis for DOE Codisposal Waste Package

In accordance with the technical work plan, ''Technical Work Plan For: Department of Energy Spent Nuclear Fuel Work Packages'' (CRWMS M&O 2000c), this Analysis/Model Report (AMR) is developed for the purpose of screening out degraded configurations for U.S. Department of Energy (DOE) spent nuclear fuel (SNF) types. It performs the degraded configuration parameter and probability evaluations of the overall methodology specified in the ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2000, Section 3) to qualifying configurations. Degradation analyses are performed to assess realizable parameter ranges and physical regimes for configurations. Probability calculations are then performed for configurations characterized by k{sub eff} in excess of the Critical Limit (CL). The scope of this document is to develop a generic set of screening criteria or models to screen out degraded configurations having potential for exceeding a criticality limit. The developed screening criteria include arguments based on physical/chemical processes and probability calculations and apply to DOE SNF types when codisposed with the high-level waste (HLW) glass inside a waste package. The degradation takes place inside the waste package and is long after repository licensing has expired. The emphasis of this AMR is on degraded configuration screening and the probability analysis is one of …

A Guide to Statistical Adjustment: How it Really Works. (open access)

A Guide to Statistical Adjustment: How it Really Works.

Congress established the Census Monitoring Board to observe and monitor all aspects of the preparation and implementation of the 2000 decennial census. After the completion of the 200 census, many thoughtful parties continue a sincere debate over the implementation of statistical adjustment as a means of increasing the accuracy of the census and for its use in redistricting and the allocation of government funds and services. On March 1, 2001, the Census Bureau's Executive Steering Committee overseeing the post-census evaluation phase, the Accuracy and Coverage Evaluation (A.C.E.), recommended against adjusting the count. Reasonable people, including leading statisticians, have reviewed the statistical adjustment methodology and have raised legitimate questions. This report attempts to put that methodology into perspective and add to what will be further debate and discussion on how all of us as shareholders can continue to work together to ensure the most accurate census possible.

High Average Power Yb:YAG Laser (open access)

High Average Power Yb:YAG Laser

We are working on a composite thin-disk laser design that can be scaled as a source of high brightness laser power for tactical engagement and other high average power applications. The key component is a diffusion-bonded composite comprising a thin gain-medium and thicker cladding that is strikingly robust and resolves prior difficulties with high average power pumping/cooling and the rejection of amplified spontaneous emission (ASE). In contrast to high power rods or slabs, the one-dimensional nature of the cooling geometry and the edge-pump geometry scale gracefully to very high average power. The crucial design ideas have been verified experimentally. Progress this last year included: extraction with high beam quality using a telescopic resonator, a heterogeneous thin film coating prescription that meets the unusual requirements demanded by this laser architecture, thermal management with our first generation cooler. Progress was also made in design of a second-generation laser.

Human Subjects Research: HHS Takes Steps to Strengthen Protections, But Concerns Remain

Testimony issued by the General Accounting Office with an abstract that begins "At the federal level the Department of Health and Human Services (HHS) is seeking to better protect human subjects in biomedical research by enhancing the visibility of its human subjects protection activities, improving its monitoring of compliance with relevant regulations by institutions and investigators, and strengthening enforcement of those regulations. HHS has also issued new guidance and is collecting information to improve oversight and monitoring at the institutional level. HHS activities directed at the investigator level consist largely of educational efforts to heighten investigators' awareness of and compliance with ethical policies and practices in conducting research. Overall, HHS' actions appear promising, but GAO has some concerns about the pace and scope of HHS' efforts to ensure the safety and protection of participants in clinical trials."

Nonlinear Gyroviscous Force in a Collisionless Plasma (open access)

Nonlinear Gyroviscous Force in a Collisionless Plasma

Nonlinear gyroviscous forces in a collisionless plasma with temperature variations are calculated from the gyrofluid moments of the gyrokinetic Vlasov equation. The low-frequency gyrokinetic ordering and electrostatic perturbations are assumed, and an additional finite Larmor radius (FLR) expansion is performed. This approach leads naturally to an expression for the gyroviscous force in terms of the gyrocenter distribution function, thus including all resonant effects, and represents a systematic FLR expansion in a general form (no assumption of any closure is made). The expression for the gyroviscous force is also calculated in terms of the particle-fluid moments by making the transformation from the gyrocenter to particle coordinates. The calculated expression represents a modification of the Braginskii gyroviscosity for a collisionless plasma with nonuniform temperature. It is compared with previous calculations based on the traditional fluid approach. As a byproduct of the gyroviscosity calculations, we derive a set of nonlinear reduced gyrofluid (and a corresponding set of particle-fluid) moment equations with FLR corrections, which exhibit a generalized form of the ''gyroviscous cancellation.''

Rare and forbidden decays of D Mesons (open access)

Rare and forbidden decays of D Mesons

The authors summarize the results of two recent searches for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D{sup +}, D{sub s}{sup +}, and D{sup 0} mesons (and their antiparticles) into modes containing muons and electrons. using data from Fermilab charm hadroproduction experiment E791, they examined D{sup +} and D{sub s}{sup +} {pi}{ell}{ell} and {Kappa}{ell}{ell} decay modes and the D{sup 0} dilepton decay modes containing either {ell}{sup +}{ell}{sup {minus}}, a {rho}{sup 0}, {bar {Kappa}}*{sup 0}, or {phi} vector meson, or a non-resonant {pi}{pi}, {Kappa}{pi}, or {Kappa}{Kappa} pair of pseudoscalar mesons. No evidence for any of these decays was found. Therefore, the authors presented branching-fraction upper limits at 90% confidence level for the 51 decay modes examined. Twenty-six of these modes had no previously reported limits, and eighteen of the remainder were reported with significant improvements over previously published results.

Simulating Marvel with the Stun Code (open access)

Simulating Marvel with the Stun Code

MARVEL, a nuclear-driven shock-tube experiment, consisted of a 2.2 kiloton nuclear explosive detonated 176 meters underground at one end of a 122-meter long, 1-meter diameter horizontal tunnel. Vaporization of material in the immediate vicinity of the explosive provided the source of high-energy driver gas. The driven gas was the ambient atmospheric air in the tunnel. The event was staged as an experimental and calculational study of the time dependent .ow of energy in the tunnel and surrounding alluvium. In this report we describe the derivation and implementation of a ''1-3/4D'' hydrocode to simulate the experiment. Calculations were performed to study the influence of energy transport to, and mass ablation from, the walls of the tunnel on the shock velocity.

Space Launch Vehicles: Government Activities, Commercial Competition, and Satellite Exports

Launching satellites into orbit, once the exclusive domain of the U.S. and Soviet governments, today is an industry in which companies in the United States, Europe, China, Russia, Ukraine, Japan, and India compete. In the United States, the National Aeronautics and Space Administration (NASA) continues to be responsible for launches of its space shuttle, and the Air Force has responsibility for launches associated with U.S. military and intelligence satellites, but all other launches are conducted by private sector companies. Since the early 1980s, Congress and successive Administrations have taken actions, including passage of several laws, to facilitate the U.S. commercial space launch services business. The Federal Aviation Administration (FAA) regulates the industry.
