3-D Experimental Fracture Analysis at High Temperature
T*e, which is an elastic-plastic fracture parameter based on incremental theory of plasticity, was determined numerically and experimentally. The T*e integral of a tunneling crack in 2024-T3 aluminum, three point bend specimen was obtained through a hybrid analysis of moire interferometry and 3-D elastic-plastic finite element analysis. The results were verified by the good agreement between the experimentally and numerically determined T*e on the specimen surface.

3(omega) Damage: Growth Mitigation
The design of high power UV laser systems is limited to a large extent by the laser-initiated damage performance of transmissive fused silica optical components. The 3{omega} (i.e., the third harmonic of the primary laser frequency) damage growth mitigation LDRD effort focused on understanding and reducing the rapid growth of laser-initiated surface damage on fused silica optics. Laser-initiated damage can be discussed in terms of two key issues: damage initiated at some type of precursor and rapid damage growth of the damage due to subsequent laser pulses. The objective of the LDRD effort has been the elucidation of laser-induced damage processes in order to quantify and potentially reduce the risk of damage to fused silica surfaces. The emphasis of the first two years of this effort was the characterization and reduction of damage initiation. In spite of significant reductions in the density of damage sites on polished surfaces, statistically some amount of damage initiation should always be expected. The early effort therefore emphasized the development of testing techniques that quantified the statistical nature of damage initiation on optical surfaces. This work led to the development of an optics lifetime modeling strategy that has been adopted by the NIF project to …

3(omega) Power Balance Procedure on the NIF
This document defines the detailed NIF full system shot procedure to obtain 8% power balance as specified by the SDR002 3.2.1.04. Because the 48 quads of the NIF will be set up over a period of five years, obtaining power balance will naturally be accomplished in two steps. First, as each quad is brought online, the four laser beams within each quad will be tuned by setting the PABTS splitter ratios so that each beam will give the same laser power on target during low energy square pulse shots. During the quad activation period all of the technical tools and procedures will be developed that are needed for attaining full laser power balance. After the initial settings of the 48 PABTS, if no other tuning is done the overall NIF power balance is expected to be about <15%. In the second step, an iteration procedure with approximately 18 full laser system shots will be needed to obtain 8% power balance by tuning out the remaining systematic differences among the quads to an acceptable small difference of 2% rms (at 3{omega}). This rms difference is smaller than the expected variation of the injection energy or the amplifier gain, and is also …

A 3-year plan for beam science in the heavy-ion fusion virtual national laboratory
In December 1998, LBNL Director Charles Shank and LLNL Director Bruce Tarter signed a Memorandum of Agreement to create the Heavy-Ion Fusion Virtual National Laboratory (HIF-VNL) with the purpose of improving the efficiency and productivity of heavy ion research through coordination of the two laboratories' efforts under one technical director. In 1999, PPPL Director Robert Goldston signed the VNL MOA for PPPL's heavy-ion fusion group to join the VNL. LBNL and LLNL each contribute about 45% of the $10.6 M/yr trilab VNL effort, and PPPL contributes currently about 10% of the VNL effort. The three labs carry out collaborative experiments, theory and simulations of a variety of intense beam scientific issues described below. The tri-lab HIF VNL program is part of the DOE Office of Fusion Energy Sciences (OFES) fusion program. A short description of the four major tasks areas of HIF-VNL research is given in the next section. The task areas are: High Current Experiment, Final Focus/Chamber Transport, Source/Injector/Low Energy Beam Transport (LEBT), and Theory/Simulation. As a result of the internal review, more detailed reviews of the designs, costs and schedules for some of the tasks have been completed, which will provide more precision in the scheduled completion dates …

25 Can Verification Report for the LLNL Plutonium Packaging System (PuPS)
This document reports the results of the 25 Can Verification Run. The 25 Can Verification Run was performed as outlined in Section 1.d of SRS Acceptance Criteria (Reference 1). The run was performed over the period of February 16 to the 28, 2001. Each of these cans was welded with a dummy Inner Can containing about 5 kg of surrogate material. The cans were then analyzed using radiography and metallography of samples taken at four locations of the weld. The radiographs were examined for porosity. The micrographs of the metallurgical samples were examined for porosity, cracks, and lack of fusion. The results were reviewed by Derrill Rikard (a level 3 inspector at LLNL) and by Ken Durland (a level 3 inspector from WSRC). These reviews did not find anything of concern. Therefore we are submitting these results to SRS for concurrence.

160 C PROTON EXCHANGE MEMBRANE (PEM) FUEL CELL SYSTEM DEVELOPMENT
The objectives of this program were: (a) to develop and demonstrate a new polymer electrolyte membrane fuel cell (PEMFC) system that operates up to 160 C temperatures and at ambient pressures for stationary power applications, and (b) to determine if the GTI-molded composite graphite bipolar separator plate could provide long term operational stability at 160 C or higher. There are many reasons that fuel cell research has been receiving much attention. Fuel cells represent environmentally friendly and efficient sources of electrical power generation that could use a variety of fuel sources. The Gas Technology Institute (GTI), formerly Institute of Gas Technology (IGT), is focused on distributed energy stationary power generation systems. Currently the preferred method for hydrogen production for stationary power systems is conversion of natural gas, which has a vast distribution system in place. However, in the conversion of natural gas into a hydrogen-rich fuel, traces of carbon monoxide are produced. Carbon monoxide present in the fuel gas will in time cumulatively poison, or passivate the active platinum catalysts used in the anodes of PEMFC's operating at temperatures of 60 to 80 C. Various fuel processors have incorporated systems to reduce the carbon monoxide to levels below 10 ppm, …

200 West Area Dust Mitigation Strategies
Various strategies were developed for the purpose of mitigating respirable dust experienced at facilities in the southwest corner of the 200 West Area. These strategies focused on treatment of that portion of the dust source located within the 200 West Expansion Area. Strategies included direct shielding of the facilities via establishment of a poplar windbreak and installation of an artificial windscreen; soil stabilization via seeding of herbaceous plants, soil fixatives, straw crimping, straw blankets, gravel mulches, drift fences, baled straw, and living fences; and various irrigation systems that would function both to water seeded herbs and to suppress dust.

527 Organizations: Reporting Requirements Imposed on Political Organizations after the Enactment of P.L. 106-230
On July 1, 2000, President Clinton signed H.R. 4762, P.L. 106-230. The law amended the Internal Revenue Code [IRC] to require political organizations described in IRC § 527 to disclose their political activities, if they were not already required to do so by the Federal Election Campaign Act [FECA]. This report summarizes the three major changes made by the law and some of the major responses to the legislation. First, all 527 organizations which expect to have over $25,000 in gross receipts during a taxable year and which are not required to report to the Federal Election Commission [FEC] are required to register with the IRS within 24 hours of their formation, whether they are involved in state, local, or federal elections. Second, 527 issue advocacy organizations, which previously reported neither to the IRS nor the FEC, are required to file regular disclosure statements with the IRS. Third, all 527 organizations with gross receipts in excess of $25,000 per year are required to file annual reports with the IRS. The registration statements, disclosure forms, and annual reports will be made public. H.R. 527 and S. 527 in the 107th Congress would exempt most state and local 527 organizations from the …

1995 NPTS Databook
Policymakers rely on transportation statistics, including data on personal travel behavior, to formulate strategic transportation policies and to improve the safety and efficiency of the U.S. transportation system. Data on personal travel trends are needed to examine the reliability, efficiency, capacity, and flexibility of the Nation's transportation system to meet current demands and accommodate future demands; to assess the feasibility and efficiency of alternative congestion-alleviating technologies (e.g., high-speed rail, magnetically levitated trains, intelligent vehicle and highway systems); to evaluate the merits of alternative transportation investment programs; and to assess the energy-use and air-quality impacts of various policies. To address these data needs, the Department of Transportation (DOT) initiated an effort in 1969 to collect detailed data on personal travel. The 1969 survey was the first Nationwide Personal Transportation Survey (NPTS). The survey was conducted again in 1977, 1983, 1990, and 1995. The 1995 survey was cosponsored by four DOT agencies: Federal Highway Administration (FHWA), Bureau of Transportation Statistics (BTS), Federal Transit Administration (FTA), and National Highway Traffic Safety Administration (NHTSA). The primary objective of the survey was to collect trip-based data on the nature and characteristics of personal travel. Commercial and institutional travel were not part of the survey.

2000 Census: Analysis of Fiscal Year 2000 Budget and Internal Control Weaknesses at the U.S. Census Bureau
A letter report issued by the General Accounting Office with an abstract that begins "In September 2000, the U.S. Census Bureau told Congress that it had at least $305 million in budget savings out of its $4.5 billion fiscal year 2000 no-year appropriations for the 2000 decennial census. Of the $4.5 billion appropriated to the U.S. Census Bureau in fiscal year 2000, lower-than-expected expenditures and obligations resulted in available balances of at least $415 million. A lower-than-expected support staff workload reduced salary and benefit costs by about $348 million. Enumerator workload is largely determined by the initial mail response rate for returned census questionnaires. The initial mail response of 64 percent meant that Census enumerators did not have to visit more than three million American households. However, the available balances from the higher mail response rate and the lower support staff workload were partially offset by about $100 million of higher salary and benefit costs for enumerators, including a higher workload for unanticipated recounts. According to Bureau data, enumerator productivity did not significantly affect budget variances for the 2000 decennial census. The Bureau reported the national average time to visit a household and complete a census questionnaire was about the …

2000 Census: Better Productivity Data Needed for Future Planning and Budgeting
A letter report issued by the General Accounting Office with an abstract that begins "Nonresponse follow-up was the most expensive and labor-intensive of all Census 2000 operations. The Census Bureau spent $1.2 billion and used more than 500,000 enumerators to obtain census information from 42 million nonresponding households in less than 10 weeks. Because of this colossal workload, even small variations in productivity had significant cost implications. Workload and enumerator productivity have historically been two of the largest drivers of census costs, and the Bureau developed its budget model for the 2000 Census using key assumptions about these two variables. Nationally, enumerators completed their nonresponse follow-up workload at a rate of 1.04 housing units per hour--slightly exceeding the Bureau's expected rate of 1.03 housing units per hour. Productivity varied for the four primary types of local census offices, ranging from 0.90 housing units per hour in inner-city and urban areas to 1.10 cases per hour in rural areas. In refining the data, the Bureau corrected what it considered to be the most significant discrepancy--a misclassification of some employees' time charges that overstated the number of hours worked by nonresponse follow-up enumerators and understated enumerator production rates."

2000 Census: Coverage Evaluation Interviewing Overcame Challenges, but Further Research Needed
A letter report issued by the General Accounting Office with an abstract that begins "As part of its Accuracy and Coverage Evaluation (ACE), the U.S. Census Bureau interviewed people across the country to develop an estimate of the number of persons missed, counted more than once, or otherwise improperly counted in the 2000 census. In conducting the interviews, which took place in person or over the phone, Census faced several challenges, including (1) completing the operation on schedule, (2) ensuring data quality, (3) overcoming unexpected computer problems, (4) obtaining a quality address list, and (5) keeping the interviews independent of census follow-up operations to ensure unbiased estimates of census errors. The Bureau completed the interviews largely ahead of schedule. On the basis of the results of its quality assurance program, the Bureau assumes that about one-tenth of one percent of all cases nationally would have failed the program because they were believed to have been falsified. Early on, the Bureau dealt with an unexpected problem with its automated work management system, which allows supervisors to selectively reassign work among interviewers. According to the Bureau officials, the Bureau addressed the underlying programming error within two weeks, and the operations proceeded on …

2000 Census: Review of Partnership Program Highlights Best Practices for Future Operations
A letter report issued by the General Accounting Office with an abstract that begins "To take a more complete and accurate count of the nation's population in the 2000 Census, the Bureau of the Census partnered with other federal agencies, as well as with state, local, and tribal governments; religious, community, and social service organizations; and private businesses. According to the Bureau, about 140,000 organizations participated in the partnership program by assisting in such critical activities as reviewing and updating the Bureau's address list, encouraging people--especially hard-to-count populations--to participate in the census, and recruiting temporary census employees. GAO found that the Bureau spent about $142.9 million on its partnership program, or about two percent of the estimated $6.5 billion the Bureau allocated for the census and an average of about $1.19 for each of the 120 million households that the Bureau estimates are in the nation. The Bureau staffed the partnership program with 594 full-time positions, of which 560 were allocated to the field, while the remaining slots were located in the Bureau's headquarters. Decisions on which organizations to partner with and what events to attend were governed by unwritten guidelines and criteria and were driven by the Bureau's desire …

2000 Census: Significant Increase in Cost Per Housing Unit Compared to 1990 Census
A letter report issued by the General Accounting Office with an abstract that begins "The estimated $6.5 billion full-cycle cost of the 2000 decennial census is nearly double that of the 1990 census. When the full-cycle cost is divided by the number of American households, the cost per housing unit of the 2000 census was $56 compared to $32 per housing unit for the 1990 census. The primary reasons for the cost increases include the following: (1) in the 1990 census, field data collection cost was $16 per housing unit, while in the 2000 census it was $32 per housing unit; (2) in the 1990 census, technology costs were $5 per housing unit compared to $8 per housing unit for the 2000 census; and (3) the data content and products activity cost $3 per housing unit in 1990 and $5 per housing unit in 2000."

2000 Transportation Baseline Report (DOE/ID-10754), 2000 Transporation Challenges,
The 2000 U. S. Department of Energy (DOE) Environmental Management (EM) Waste and Materials Disposition “Transportation Challenges” report is provided as an update to or status report on the transportation “barriers” analysis conducted in October 1999 and published in November 1999 as the National Transportation Program (NTP) Transportation Challenges “Problems Tied to Disposition Pathways.” Much of the programmatic information concerning the “barriers” or, more accurately, “issues,” has not changed since the first publication; however, efforts to resolve the issues have progressed to varying degrees over the last year. This report provides a current status of efforts to eliminate or mitigate the issues, and includes new issues identified since the original analyses were conducted. Resolving these issues will increase the probability of successful waste and materials disposition and decrease the likelihood of delays due to inadequate transportation resources or infrastructure. The issues addressed in this report generally affect more than one site and more than one waste or material stream.
