Drift seepage refers to flow of liquid water into repository emplacement drifts, where it can potentially contribute to degradation of the engineered systems and release and transport of radionuclides within the drifts. Because of these important effects, seepage into emplacement drifts is listed as a ''principal factor for the postclosure safety case'' in the screening criteria for grading of data in Attachment 1 of AP-3.15Q, Rev. 2, ''Managing Technical Product Inputs''. Abstraction refers to distillation of the essential components of a process model into a form suitable for use in total-system performance assessment (TSPA). Thus, the purpose of this analysis/model is to put the information generated by the seepage process modeling in a form appropriate for use in the TSPA for the Site Recommendation. This report also supports the Unsaturated-Zone Flow and Transport Process Model Report. The scope of the work is discussed below. This analysis/model is governed by the ''Technical Work Plan for Unsaturated Zone Flow and Transport Process Model Report'' (CRWMS M&O 2000a). Details of this activity are in Addendum A of the technical work plan. The original Work Direction and Planning Document is included as Attachment 7 of Addendum A. Note that the Work Direction and Planning …

An adaptive path planning algorithm is presented for cooperating Unmanned Air Vehicles (UAVs) that are used to deploy and operate land-based sensor networks. The algorithm employs a global cost function to generate paths for the UAVs, and adapts the paths to exceptions that might occur. Examples are provided of the paths and adaptation.

We consider an interior penalty discontinuous approximation for symmetric elliptic problems of second order on non-matching grids in this paper. The main result is an almost optimal error estimate for the interior penalty approximation of the original problem based on the partition of the domain into a finite number of subdomains. Further, an error analysis for the finite element approximation of the penalty formulation is given. Finally, numerical experiments on a series of model second order problems are presented.

Testimony issued by the General Accounting Office with an abstract that begins "This testimony focuses on the Alternative Minimum Tax (AMT), its interaction with the regular tax system, and its projected growth in coverage. GAO found that (1) AMT was designed to ensure that high-income individuals do not avoid significant income tax liabilities--for tax year 1997, about 14,000 taxpayers would not have paid any income taxes absent AMT, (2) AMT operates as a separate tax system that parallels the regular individual income tax system but with different rules for determining taxable income, different tax rates for computing tax liability, and different rules for allowing the use of tax credits, (3) AMT affected about one percent of taxpayers in 2000 and accounted for about $5.8 billion in additional tax revenue; by 2010, it is expected to increase the tax liabilities of about one out of six taxpayers and account for about $189 billion in tax revenues over the period, (4) the projected increase in AMT coverage is, for the most part, attributable to inflation and to the scheduled expiration of legislation temporarily excluding some tax credits from AMT rules, and (5) AMT's impacts include increased taxpayer compliance burden; increased Internal Revenue …

Adaptive mesh refinement is complicated by both the algorithms and the dynamic nature of the computations. In parallel the complexity of getting good performance is dependent upon the architecture and the application. Most attempts to address the complexity of AMR have lead to the development of library solutions, most have developed object-oriented libraries or frameworks. All attempts to date have made numerous and sometimes conflicting assumptions which make the evaluation of performance of AMR across different applications and architectures difficult or impracticable. The evaluation of different approaches can alternatively be accomplished through simulation of the different AMR processes. In this paper we outline our research work to simulate the processing of adaptive mesh refinement grids using a distributed array class library (P++). This paper presents a combined analytic and empirical approach, since details of the algorithms can be readily predicted (separated into specific phases), while the performance associated with the dynamic behavior must be studied empirically. The result, AMRSim, provides a simple way to develop bounds on the expected performance of AMR calculations subject to constraints given by the algorithms, frameworks, and architecture.

A high-temperature (300 C), high-pressure (18 MPa), and high-leak rate (1500 L/min) facility, and a room temperature, high-pressure (52 MPa) test facility were used to test flawed steam generator tubes. Single and multiple rectangular flaws were fabricated by electro-discharge machining on the outside surface of the tubes. This paper briefly reviews analytical methods for predicting ligament rupture and unstable burst of tubes with single and multiple rectangular flaws. Test data are presented to validate the failure models. The ligament rupture pressure of specimens with multiple flaws predicted by an equivalent rectangular crack method agree fairly well with measured data.

The objective of this Class 3 project was demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstone's of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost effective way to recover oil more economically through geologically based field development. This project was focused on East Ford field, a Delaware Mountain Group field that produced from the upper Bell Canyon Formation (Ramsey sandstone). The field, discovered in 9160, is operated by Oral Petco, Inc., as the East Ford unit. A CO2 flood was being conducted in the unit, and this flood is the Phase 2 demonstration for the project.

An assessment has been performed for an Accelerator Transmutation of Waste (ATW) concept based on the use of the high temperature gas reactor technology. The concept has been proposed by General Atomics for the ATW system. The assessment was jointly conducted at Argonne National Laboratory (ANL) and Los Alamos national laboratory to assess and to define the potential candidates for the ATW system. This report represents the assessment work performed at ANL. The concept uses recycled light water reactor (LWR)-discharge-transuranic extracted from irradiated oxide fuel in a critical and sub-critical accelerator driven gas-cooled transmuter. In this concept, the transmuter operates at 600 MWt first in the critical mode for three cycles and then operates in a subcritical accelerator-driven mode for a single cycle. The transmuter contains both thermal and fast spectrum transmutation zones. The thermal zone is fueled with the TRU oxide material in the form of coated particles, which are mixed with graphite powder, packed into cylindrical compacts, and loaded in hexagonal graphite blocks with cylindrical channels; the fast zone is fueled with TRU-oxide material in the form of coated particles without the graphite powder and the graphite blocks that has been burned in the thermal region for three …

The purpose of this report is to identify the potential for on-site power generation in the U.S. industrial sector with emphasis on nine industrial groups called the ''Industries of the Future'' (IOFs) by the U.S. Department of Energy (DOE). Through its Office of Industrial Technologies (OIT), the DOE has teamed with the IOFs to develop collaborative strategies for improving productivity, global competitiveness, energy usage and environmental performance. Total purchases for electricity and steam for the IOFs are in excess of $27 billion annually. Energy-related costs are very significant for these industries. The nine industrial groups are (1) Agriculture (SIC 1); (2) Forest products; (3) Lumber and wood products (SIC 24); (4) Paper and allied products (SIC 26); (5) Mining (SIC 11, 12, 14); (6) Glass (SIC 32); (7) Petroleum (SIC 29); (8) Chemicals (SIC 28); and (9) Metals (SIC 33): Steel, Aluminum, and Metal casting. Although not currently part of the IOF program, the food industry is included in this report because of its close relationship to the agricultural industry and its success with on-site power generation. On-site generation provides an alternative means to reduce energy costs, comply with environmental regulations, and ensure a reliable power supply. On-site generation can …

Modern antennas especially arrays are being placed in layers of materials on complex environments. This technique produces aesthetically pleasing structures if necessary, allows for more freedom in structure planning, and can improve antenna performance. In the past, buried antennas have been studied by numerous authors such as in Reference. Recent work on this subject uses spectral and/or numerical moment method formulations. For high frequency analysis it is important to find efficient and accurate methods for design purposes. A rigorous recursive method for plane waves reflection and transmission coefficients by Richmond has been used in the past for dipoles above multilayer slabs. This solution is modified in this paper to account for forward and backward traveling rays with appropriate spread factors for a dipole in the media. Extensive validation for this approximate method shows good agreement with a Method of Moments code. This code is developed at Lawrence Livermore National Laboratory. The geometry for these comparisons uses a dipole in nontruncated dielectric multilayer slabs.

The authors discuss the decay of axion walls bounded by strings and present numerical simulations of the decay process. In these simulations, the decay happens immediately, in a time scale of order the light travel time, and the average energy of the radiated axions is <w{sub a}> {approx_equal} 7m{sub a} for v{sub a}/m{sub a} {approx_equal} 500. <w{sub a}> is found to increase approximately linearly with ln(v{sub a}/m{sub a}). Extrapolation of this behavior yields <w{sub a}> {approx_equal} 60 m{sub a} in axion models of interest.

Beam stability issues of the VLHC rings in Phase 1 and Phase 2 are reviewed. For accelerator rings of circumference 232 km and beam pipe radius of the order of 1 cm, the impedance of the vacuum chamber is dominated by the resistive wall. The most dangerous instabilities are the single-bunch transverse mode coupling instability and the transverse coupled bunch instability driven by the resistive wall at sub-revolution frequency. Scaling is studied concerning the thresholds of these instabilities and the dominance of the resistive wall impedance as the size of the accelerator increases.

The COPS test set provides a modest selection of difficult nonlinearly constrained optimization problems from applications in optimal design, fluid dynamics, parameter estimation, and optimal control. In this report we describe version 2.0 of the COPS problems. The formulation and discretization of the original problems have been streamlined and improved. We have also added new problems. The presentation of COPS follows the original report, but the description of the problems has been streamlined. For each problem we discuss the formulation of the problem and the structural data in Table 0.1 on the formulation. The aim of presenting this data is to provide an approximate idea of the size and sparsity of the problem. We also include the results of computational experiments with the LANCELOT, LOQO, MINOS, and SNOPT solvers. These computational experiments differ from the original results in that we have deleted problems that were considered to be too easy. Moreover, in the current version of the computational experiments, each problem is tested with four variations. An important difference between this report and the original report is that the tables that present the computational experiments are generated automatically from the testing script. This is explained in more detail in the …

A chapter report issued by the General Accounting Office with an abstract that begins "This report examines how best practices offer improvements to the way the Department of Defense defines and matches weapon system requirements to available resources such as cost, schedule, and mature technologies. GAO identified three factors that were key to matching needs and resources before product development began. First, developers employed the technique of systems engineering to identify gaps between resources and customer needs before committing to a new product development. Second, customers and developers were flexible. Leeway existed to reduce or defer customer needs to future programs or for the developer to make an investment to increase knowledge about a technology or design feature before beginning product development. Third, the roles and responsibilities of the customer and the product developer were matched, with the product developer being able to determine or significantly influence product requirements. In cases where these factors were not present at program launch, product development began without a match between requirements and resources. Invariably, this imbalance favored meeting customer needs by adding resources, which resulted in increased costs and later deliveries."

A letter report issued by the General Accounting Office with an abstract that begins "During its review of 2001 agency budget justifications, GAO found several capital project funding requests that lacked total project cost information and for which it was not always clear whether requested funding would provide a useful, stand-alone asset. Without this information, Congress cannot consider the full costs of proposed commitments or determine if it is funding an asset that will be useful without additional funding. This report provides several examples of agency capital project funding request information that could be improved."

A letter report issued by the General Accounting Office with an abstract that begins "The Bureau of Land Management's (BLM) Mining Law Administration Program (MLAP) is responsible for managing the environmentally responsible exploration and development of locatable minerals on public lands. The program is funded through mining fees collected from the holders of unpatented mining claims and sites and by appropriations to the extent that fees are inadequate to fund the program. Congress and program managers need accurate cost information in order to make informed program and budgeting decisions. However, GAO found that BLM's financial records did not accurately reflect the true costs of its programs because the costs of labor and a number of contracts and services costs were charged to MLAP and not to the appropriate program. As a result, other subactivities benefited from the charging of these improper costs and fewer funds have been available for actual MLAP operations. BLM has taken steps to make correcting adjustments for improper charges to MLAP contracts and services; however, additional adjustments are needed to correct for labor costs that were improperly charged to MLAP. Until these adjustments for improperly charged labor are made, Congress and program managers can place only …

The CDF Run I B physics program has been very successful, making numerous measurements over a wide variety of B physics topics. Measurements have included masses and lifetimes; discovery of the B{sub c}; B{sub s} {r_arrow} J/{psi}{phi} polarization; B{sup 0} {leftrightarrow} {bar B}{sup 0} mixing; sin (2{beta}); and rare decay limits. Recent results include a search for {Lambda}{sub b} {r_arrow} {Lambda}{gamma} and a study of B{sup 0} {r_arrow} J/{psi}K(*){sup 0} {pi}{sup +}{pi}{sup {minus}} decays. The tools and experience developed during Run I are quite valuable as CDF enters Run II.
