Over the past decade, worldwide production of illicit drugs has risen dramatically: opium and marijuana production has roughly doubled and coca production tripled. Street prices of cocaine and heroin have fallen significantly in the past 20 years, reflecting increased availability. Despite apparent national political resolve to deal with the drug problem, inherent contradictions regularly appear between U.S. anti-drug policy and other national policy goals and concerns. The mix of competing domestic and international pressures and priorities has produced an ongoing series of disputes within and between the legislative and executive branches concerning U.S. international drug policy. One contentious issue has been the Congressionally-mandated certification process, an instrument designed to induce specified drug-exporting countries to prioritize or pay more attention to the fight against narcotics businesses.

A letter report issued by the General Accounting Office with an abstract that begins "The Indian gambling industry has flourished since the enactment of the Indian Gaming Regulatory Act in 1988. Nearly 200 tribes generated about $10 billion in annual revenues in 1999 from their gambling operations. Because of weaknesses in the federal recognition process, the basis for tribal recognition decisions by the Bureau of Indian Affairs (BIA) is not always clear and the length of time involved can be substantial. Despite an increasing workload, the number of BIA staff assigned to evaluate the petitions has fallen by about 35 percent since 1993. Just as important, the process lacks effective procedures for promptly addressing the increased workload. In particular, the process does not impose effective deadlines that create a sense of urgency, and procedures for providing information to interested third parties are ineffective. GAO summarized this report in testimony before Congress; see: Indian Issues: More Consistent and Timely Tribal Recognition Process Needed, by Barry T. Hill, Director for Natural Resources and Environment, before the Subcommittee on Energy Policy, Natural Resources and Regulatory Affairs, House Committee on Government Reform. GAO-01-415T, Feb. 7 (nine pages)."

A letter report issued by the General Accounting Office with an abstract that begins "About 80 means-tested federal programs assisted low-income people in 1998. GAO reviewed 11 programs that assisted families and individuals with income, food, medical assistance, and housing. Despite substantial overlap in the populations they serve, the 11 programs varied significantly in their financial eligibility rules. At the most basic level, the dollar levels of the income limits--the maximum amounts of income an applicant can have and still be eligible for a program--vary across programs. Beyond this, differences exist in the income rules, such as whose income and what types of income are counted. The variations and complexity of the federal financial eligibility rules, along with other factors, have led to processes that are often duplicative and cumbersome for both caseworkers and applicants. Overall, federal, state, and local entities have made little progress in simplifying or coordinating eligibility determination processes. States realigned some of the financial rules, but only to a limited extent. Another approach uses computer systems to establish joint eligibility determination processes that a single caseworker can administer. Efforts to simplify or better coordinate eligibility determination processes confront many obstacles, including restrictive federal program statutes and …

Accumulations of two solid phases have formed scale deposits in the Savannah River Site 2H Evaporator system since late 1996. The aluminosilicate scale deposits caused the evaporator pot to become inoperable in October 1999. Accumulations of the diuranate phase have caused criticality concerns in the SRS 2H Evaporator. In order to ensure that similar deposits are not and will not form in the SRS 3H Evaporator, thermodynamically derived activity diagrams specific to the feeds processed from Tanks 30 and 32 are evaluated in this report.

This report proposes and documents a computational benchmark problem for the estimation of the additional reactivity margin available in spent nuclear fuel (SNF) from fission products and minor actinides in a burnup-credit storage/transport environment, relative to SNF compositions containing only the major actinides. The benchmark problem/configuration is a generic burnup credit cask designed to hold 32 pressurized water reactor (PWR) assemblies. The purpose of this computational benchmark is to provide a reference configuration for the estimation of the additional reactivity margin, which is encouraged in the U.S. Nuclear Regulatory Commission (NRC) guidance for partial burnup credit (ISG8), and document reference estimations of the additional reactivity margin as a function of initial enrichment, burnup, and cooling time. Consequently, the geometry and material specifications are provided in sufficient detail to enable independent evaluations. Estimates of additional reactivity margin for this reference configuration may be compared to those of similar burnup-credit casks to provide an indication of the validity of design-specific estimates of fission-product margin. The reference solutions were generated with the SAS2H-depletion and CSAS25-criticality sequences of the SCALE 4.4a package. Although the SAS2H and CSAS25 sequences have been extensively validated elsewhere, the reference solutions are not directly or indirectly based on experimental …

A letter report issued by the General Accounting Office with an abstract that begins "The Farm Credit Administration (FCA) regulates the farm credit system. Administrative expenses, which accounted for about 97 percent of FCA's total operating expenses of $34.5 million in fiscal year 2000, are funded primarily by assessments on the institutions that make up the system, including the Federal Agricultural Mortgage Corporation (Farmer Mac). This report (1) analyses trends in administrative expenses for fiscal years 1996 through 2000 and (2) compares ways that FCA and other federal financial regulators calculate the assessments they need to fund their operations. GAO found that although FCA's administrative expenditures varied each year between 1996 and 2000, they remained below 1996 levels and stayed within congressionally imposed annual spending limits for each year during 1997 through 2000. Between 1996 and 2000, the agency experienced a decline in administrative spending of around $2 million, or 5.8 percent. Personnel costs were the largest single expense, consistently accounting for more than 80 percent of administrative spending; thus, a 15 percent staff reduction also provided the greatest overall savings. Unlike many government agencies whose operations are funded by taxpayers' money, the federal financial regulators are self-funded agencies that …

A letter report issued by the General Accounting Office with an abstract that begins "To deter illegal entry between the nation's ports of entry, the Immigration and Naturalization Service (INS) developed its Southwest Border Strategy. INS has spent seven years implementing the border strategy, but it may take INS up to a decade longer to fully implement the strategy. This assumes that INS obtains the level of staff, technology, equipment, and fencing it believes it needs to control the Southwest border. Although illegal alien apprehensions have shifted, there is no clear indication that overall illegal entry into the United States along the Southwestern border has declined. INS' current efforts to measure the effectiveness of its border control efforts could be enhanced by analyzing the data in its automated biometric identification system (IDENT). These data offer INS an opportunity to develop additional performance indicators that could be incorporated into its Annual Performance Plan review process and could help INS assess whether its border control efforts are associated with an overall reduction in the flow of illegal aliens across the border. Borderwide analysis of the IDENT data could be used to address several important questions related to illegal entry. The strategy's impact …

Accelerator mass spectrometry (AMS) is an isotope-ratio measurement technique developed in the late 1970s for tracing long-lived radioisotopes (e.g., {sup 14}C half life = 5760 y). The technique counts individual nuclei rather than waiting for their radioactive decay, allowing measurement of more than 100 low-level {sup 14}C samples per day (Vogel et al, 1995). The LLNL AMS system is shown in Fig.1. The contemporary quantity of {sup 14}C in living things ({sup 14}C/C = 1.2 x 10{sup -12} or 110 fmol {sup 14}C/ g C) is highly elevated compared to the quantity of {sup 14}C in petroleum-derived products. This isotopic elevation is sufficient to trace the fate of bio-derived fuel components in the emissions of an engine without the use of radioactive materials. If synthesis of a fuel component from biologically-derived source material is not feasible, another approach is to purchase {sup 14}C-labeled material (e.g., dibutyl maleate (DBM)) and dilute it with petroleum-derived material to yield a contemporary level of {sup 14}C. In each case, the virtual absence of {sup 14}C in petroleum based fuels gives a very low {sup 14}C background that makes this approach to tracing fuel components practical. Regulatory pressure to significantly reduce the particulate emissions from …

A letter report issued by the General Accounting Office with an abstract that begins "With the end of the Cold War, national security strategies changed to meet new global challenges. The Navy developed a new strategic direction in the early 1990s, shifting its primary focus from open ocean "blue water" operations to littoral, or shallow water, operations closer to shore. GAO found that although the Navy has recently placed more emphasis on transformation, it does not have a well-defined and overarching strategy for transformation. It has not clearly identified the scope and direction of its transformation; the overall goals, objectives, and milestones; or the specific strategies and resources to be used in achieving these goals. It also has not clearly identified organizational roles and responsibilities, priorities, resources, or ways to measure progress. Without a well-defined strategic plan to guide the Navy's efforts, senior leaders and Congress will not have the tools they need to ensure that the transformation is successful."

The scope of this calculation is to determine ventilation system resistances, pressure drops, airflows, and operating cost estimates for the Site Recommendation (SR) design as detailed in the ''Site Recommendation Subsurface Layout'' (BSC (Bechtel SAIC Company) 2001a). The statutory limit for emplacement of waste in Yucca Mountain is 70,000 metric tons of uranium (MTU) and is considered the base case for this report. The objective is to determine the overall repository system ventilation flow network for the monitoring phase during normal operations and to provide a basis for the system description document design descriptions. Any values derived from this calculation will not be used to support construction, fabrication, or procurement. The work scope is identified in the ''Technical Work Plan for Subsurface Design Section FY01 Work Activities'' (CRWMS M&O 2001, pp. 6 and 13). In accordance with the technical work plan this calculation was prepared in accordance with AP-3.12Q, ''Calculations'' and other procedures invoked by AP-3.12Q. It also incorporates the procedure AP-SI1.Q, ''Software Management''.

This report summarizes the Groundwater Monitoring Program conducted by SRS during fourth quarter 2000. It includes the analytical data, field data, data review, quality control, and other documentation for this program.

The purpose of this document as stated in the ''Technical Work Plan for Subsurface Design Section FY 01 Work Activities'' (CRWMS M&O 2001a, pg. 14) is to review and evaluate the most current concepts for shaft siting and configuration. The locations of the shaft sites will be evaluated in reference to the overall subsurface ventilation layout shown in Figure 1. The scope will include discussions on pad size requirements, shaft construction components such as collars, shaft stations, sumps, ground support and linings, head frames, fan ducting and facility equipping. In addition to these, shaft excavation methodologies and integration with the overall subsurface construction schedule will be described. The Technical Work Plan (TWP), (CRWMS M&O 2001a), for this document has been prepared in accordance with AP-2.21Q, ''Quality Determinations and Planning for Scientific, Engineering and Regulatory Compliance Activities''. This document will be prepared in accordance with AP-3.10Q, ''Analysis and Models''. This document contributes to Site Recommendation (SR). The intended use of this document is to provide an analysis for shaft siting and configuration criteria for subsequent construction. This document identifies preliminary design concepts that should not be used for procurement, fabrication, or construction.

A thermodynamic model based on the code SOLGASMIX is developed to calculate phase equilibrium in evaporators and related tank wastes at the Savannah River Site (SRS). This model uses the Pitzer method to calculate activity coefficients, and many of the required Pitzer parameters have been determined in the course of this work. Principal chemical species in standard SRS simulant solutions are included, and the temperature range for most parameters has been extended above 100 C. The SOLGASMIX model and calculations using the code Geochemists Workbench are compared to actual solubility data including silicate, aluminate, and aluminosilicate solutions. In addition, SOLGASMIX model calculations are also compared to transient solubility data involving SRS simulant solutions. These comparisons indicate that the SOLGASMIX predictions closely match reliable data over the range of temperature and solution composition expected in the SRS evaporator and related tanks. Predictions using the Geochemists Workbench may be unreliable, due primarily to the use of an inaccurate activity coefficient model.

Management of the High Level Waste Program Office at the Idaho National Environmental and Engineering Laboratory has projected oscillating future employment levels. A simple computer model was created to help convince management that qualitative modeling of ''soft'' variables can provide appreciable insight into the consequences and performance of alternative staffing policies. Advocacy of the model underlying the simulation or a particular strategy did not motivate the study, but rather a desire to instill enthusiasm and elicit new and improved conceptual models from management. Six qualitative and three quantitative generic insights to managing staffing levels are gained from the simulations. These insights in their generic form should be familiar to those knowledgeable of system dynamics or computer/instrument process control. Their potential usefulness to developing staffing strategies is stressed. The two primary overarching assertions that flow from the simulation results are: (1) the presence of multiple feedbacks, time delays, and continuous flows introduce instability into a personnel system that complicates the management of staffing levels. Many times ''soft'' variables, such as morale, productivity, and efficiency are the sources of such influences; and (2) such influences can be successfully modeled. In the case of the simple model used in these simulations, for example, …

The Linux kernel version 2.2.19 lacks UNIX-style raw disk support, and its SCSI layer is optimized for small transfer sizes. This report describes kernel patches to add raw disk support and enhance performance in the SCSI layer and QLA2x00 Fibre Channel device driver for large transfer sizes. Benchmarks demonstrate raw disk performance of 191 megabytes/second write, 176 megabytes/second read for one megabyte random I/O on a Compaq ES40 computer system with two QLogic QLA2200F Fibre Channel host bus adapters, each connected to two Ciprico RF7010 arrays on arbitrated loop.

The preparation of this technical report has two objectives. The first objective is to discuss the base case concepts of waste transport, emplacement, and retrieval operations and evaluate these operations relative to a lower-temperature repository design. Aspects of the operations involved in waste transport, emplacement and retrieval may be affected by the lower-temperature operating schemes. This report evaluates the effects the lower-temperature alternatives may have on the operational concepts involved in emplacing and retrieving waste. The second objective is to provide backup material for the design description, in a traceable and defensible format, for Section 2 of the Waste Emplacement/Retrieval System Description Document.

The U.S. Department of Energy (DOE) evaluated options for managing its depleted uranium hexafluoride (UF{sub 6}) inventory in the Programmatic Environmental Impact Statement for the Long-Term Management and Use of Depleted Uranium Hexafluoride (PEIS) of April 1999. Along with the impacts from other management options, the PEIS discussed the environmental impacts from the disposal of depleted uranium oxide, which could result from the chemical conversion of depleted UF{sub 6}. It has been suggested that the depleted UF{sub 6} could also be converted to uranium tetrafluoride (UF{sub 4}) and disposed of. This report considers the potential environmental impacts from the disposal of DOE's depleted UF{sub 6} inventory after its conversion to UF{sub 4}. The impacts were evaluated for the same three disposal facility options that were considered in the PEIS for uranium oxide: shallow earthen structures, belowground vaults, and mines. They were evaluated for a dry environmental setting representative of the western United States. To facilitate comparisons and future decision making, the depleted UF{sub 4} disposal analyses performed and the results presented in this report are at the same level of detail as that in the PEIS.

In a nuclear waste repository in basalt, the groundwater will have a low redox potential (Eh) which may affect the leach rate of SRP waste glass. Accurate laboratory simulations of conditions in a basalt reposition must maintain low Eh values throughout the course of the experiment. In this report, important parameters affecting the ability of basalt to maintain appropriate Eh-pH conditions are examined, in particular basalt type and groundwater simulation.

This report summarizes a study of 15 automotive fleets that operate neighborhood electric vehicles (NEVs) in the United States. The information was obtained to help Field Operations Program personnel understand how NEVs are being used, how many miles they are being driven, and if they are being used to replace other types of fleet vehicles or as additions to fleets. (The Field Operations Program is a U.S. Department of Energy Program within the DOE Office of Energy Efficiency and Renewable Energy, Transportation Technologies). The NEVs contribution to petroleum avoidance and cleaner air can be estimated based on the miles driven and by assuming gasoline use and air emissions values for the vehicles being replaced. Gasoline and emissions data for a Honda Civic are used as the Civic has the best fuel use for a gasoline-powered vehicle and very clean emissions. Based on these conservation assumptions, the 348 NEVs are being driven a total of about 1.2 million miles per year. This equates to an average of 3,409 miles per NEV annually or 9 miles per day. It is estimated that 29,195 gallons of petroleum use is avoided annually by the 348 NEVs. This equates to 87 gallons of petroleum use …
