A letter report issued by the General Accounting Office with an abstract that begins "The accuracy of the 2000 decennial census depends in part on the proper functioning of 10 interrelated information systems, one of which is the Census Bureau's headquarters (HQ) processing system. The HQ processing system consists of 48 applications, all developed internally by the Bureau, that support various census operations, such as updating address files, creating a file of census responses, and preparing data for tabulation and dissemination. GAO found that the Bureau lacks effective, mature software and system development processes to control development of its HQ processing system applications."

The nonlinear interaction between counter-propagating laser beams in a plasma results in the generation of large (enhanced) plasma wakes. The two beams need to be slightly detuned in frequency, and one of them has to be ultra-short (shorter than a plasma period). Thus produced wakes have a phase velocity close to the speed of light and can be used for acceleration and compression of charged bunches. The physical mechanism responsible for the enhanced wake generation is qualitatively described and compared with the conventional laser wakefield mechanism. The authors also demonstrate that, depending on the sign of the frequency difference between the lasers, the enhanced wake can be used as a ``snow-plow'' to accelerate and compress either positively or negatively charged bunches. This ability can be utilized in an electron-positron injector.

The purpose of this and the previous modeling is to provide quantitative input to the screening of remedial alternatives for the CMS/FS for this site.

Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This report is a guide to one of the 13 regular appropriations bills that Congress passes each year. It is designed to supplement the information provided by the House and Senate Appropriations Subcommittees on Interior and Related Agencies Appropriations.

Although it has been a high priority Army program, a number of factors have complicated the RAH-66 Comanche program. Since its inception, the program has been restructured several times–postponing the initial operational capability (IOC) and increasing overall program costs. Presently, there is debate within the Army regarding whether the program should be reduced significantly to make funds available to pursue other modernization priorities.

The purpose of the design compliance matrix (DCM) is to provide a single-source document of all design requirements associated with the fifteen subsystems that make up the rotary mode core sampling (RMCS) system. It is intended to be the baseline requirement document for the RMCS system and to be used in governing all future design and design verification activities associated with it. This document is the DCM for the RMCS system used on Hanford single-shell radioactive waste storage tanks. This includes the Exhauster System, Rotary Mode Core Sample Trucks, Universal Sampling System, Diesel Generator System, Distribution Trailer, X-Ray Cart System, Breathing Air Compressor, Nitrogen Supply Trailer, Casks and Cask Truck, Service Trailer, Core Sampling Riser Equipment, Core Sampling Support Trucks, Foot Clamp, Ramps and Platforms and Purged Camera System. Excluded items are tools such as light plants and light stands. Other items such as the breather inlet filter are covered by a different design baseline. In this case, the inlet breather filter is covered by the Tank Farms Design Compliance Matrix.

This report focuses on characterization of an off gas condensate sample from the Duratek LAW pilot melter located in Columbia, MD.

This system design description (SDD) addresses the Cold Vacuum Drying (CVD) Facility fire protection system (FPS). The primary features of the FPS for the CVD are a fire alarm and detection system, automatic sprinklers, and fire hydrants. The FPS also includes fire extinguishers located throughout the facility and fire hydrants to assist in manual firefighting efforts. In addition, a fire barrier separates the operations support (administrative) area from the process bays and process bay support areas. Administrative controls to limit combustible materials have been established and are a part of the overall fire protection program. The FPS is augmented by assistance from the Hanford Fire Department (HED) and by interface systems including service water, electrical power, drains, instrumentation and controls. This SDD, when used in conjunction with the other elements of the definitive design package, provides a complete picture of the FPS for the CVD Facility.

A letter report issued by the General Accounting Office with an abstract that begins "The United States has been providing assistance to Colombia since the early 1970s to help the Colombian National Police and other law enforcement agencies, the military, and civilian agencies reduce illegal drug production and trafficking. Recognizing that illegal drug activities are a serious problem, the Colombian government announced a counternarcotics plan known as Plan Colombia. This report reviews the U.S. counternarcotics efforts in Colombia. Although U.S.-provided assistance has enhanced Colombian counternarcotics capabilities, its usefulness has sometimes been limited because of long-standing problems in planning and implementation. For example, little progress has been made in launching a plan to have Colombia's National Police assume a larger role in managing the aerial eradication program, which requires costly U.S. contractor assistance. The governments of the United States and Colombia face continuing and new financial and management challenges in implementing Plan Colombia. The costs and activities needed to implement the plan are unknown at this time, and it will take years before any significant reduction in the drug trade is seen. Colombia must resolve problems with its political and economic stability and improve its management of counternarcotics funding in order …

Two thermal convection loops (TCLs) fabricated from 316L stainless steel and containing mercury and a variety of 316L coupons representing variable surface conditions and heat treatments have been operated continuously for 2000 h. Surface conditions included surface ground, polished, gold-coated, chemically etched, bombarded with Fe to simulate radiation damage, and oxidized. Heat treatments included solution treated, welded, and sensitized. In addition, a nitrogen doped 316L material, termed 316LN, was also examined in the solution treated condition. Duplicate TCLs were operated in this experiment--both were operated with a 305 C peak temperature, a 65 C temperature gradient, and mercury velocity of 1.2 m/min--but only one included a 36 h soak in Hg at 310 C just prior to operation to encourage wetting. Results indicate that the soak in Hg at 310 C had no lasting effect on wetting or compatibility with Hg. Further, based on examination of post-test wetting and coupon weight loss, only the gold-coated surfaces revealed significant interaction with Hg. In areas wetted significantly by Hg, the extreme surface of the stainless steel (ca 10 {micro}m) was depleted in Ni and Cr compared to the bulk composition.

This report is a summary of the basic research necessary to understand the cause of foaming in the Small Tank Tetraphenylborate Process (STTP) and to develop a short list of antifoaming and defoaming agents.

A letter report issued by the General Accounting Office with an abstract that begins "In 1994, the United States and other countries intervened militarily in Haiti to restore the democratically elected government that had been overthrown by the Haitian military several years earlier. During the last 6 years, the United States provided assistance to help Haiti establish its first civilian-controlled police and improve its judicial system. About $70 million in U.S. assistance helped Haiti recruit, train, organize, and equip a basic police force, including specialized units. However, despite these achievements, the police and judicial sector have displayed several weaknesses. The Haitian government's lack of a clear commitment to addressing the major problems of its police and judicial institutions has been the key factor affecting the success of the U.S. assistance provided to these institutions. The United States is reassessing several aspects of its relationship with Haiti because of concerns about how votes were counted in Haiti's May 2000 elections. The United States and Haiti have been unable to negotiate an agreement for continuing this assistance. At this time, any further aid to the Haitian Justice System should be linked to performance-related conditions."

This paper describes the current status of the FIRE configuration and the integration of the major subsystem components. FIRE has a major radius of 2 m, a field on axis of 10T, a plasma current of 6.4 MA. It is capable of 18 second pulses when operated with DT and 26 s when operated with DD. The general arrangement consists of sixteen wedged TF coils that surround a free standing central solenoid, a double wall vacuum vessel and internal plasma facing components that are segmented for maintenance through horizontal ports. Large rings located outside the TF coils are used to obtain a load balance between wedging of the intercoil case structure and wedging at the upper/lower inboard corners of the TF coil winding. The magnets are liquid nitrogen cooled and the entire device is surrounded by a thermal enclosure. The double wall vacuum vessel integrates cooling and shielding in a shape that maximizes shielding of ex-vessel components. Within the vacuum vessel, plasma-facing components frame the plasma. First wall tiles are attached directly to inboard and outboard vacuum vessel walls. The divertor is designed for a high triangularity, double-null plasma with a short inner null point-to-wall distance and near vertical outer …

Battelle received five samples from Hanford waste tank 241-AP-101, taken at five different depths within the tank. No visible solids or organic layer were observed in the individual samples. Individual sample densities were measured, then the five samples were mixed together to provide a single composite. The composite was homogenized and representative sub-samples taken for inorganic, radioisotopic, and organic analysis. All analyses were performed on triplicate sub-samples of the composite material. The sample composite did not contain visible solids or an organic layer. A subsample held at 10?C for seven days formed no visible solids.

A letter report issued by the General Accounting Office with an abstract that begins "This report focuses on the default rate for student loans. Two major federal student loan programs, the Federal Direct Loan Program (FDLP) and the Federal Family Education Loan Program (FFELP), together provided student borrowers with about 9 million loans totaling about $42.9 billion in fiscal year 1999. The most recent student loan default rate statistics for schools showed that, overall, the direct and guaranteed student loan programs had similar default rates: at 6.6 percent for FDLP and 6.7 percent for FFELP. The two programs had similar default rates when the comparisons focused on the type of school. FDLP has two types of loans, consolidated and nonconsolidated. Generally, borrowers with consolidated loans who used the standard payment plan had a lower default rate than did borrowers with nonconsolidated loans. However, when income contingent repayment plans were used, borrowers with consolidated loans had a higher default rate than did those with nonconsolidated loans. The Department of Education uses various procedures to ensure that loans are properly serviced and collected, including independent monitoring and external assessments of monitoring results."
