Field leachate samples are being collected from coal combustion product (CCP) management sites from several geographic locations in the United States to provide broad characterization of major and trace constituents in the leachate. In addition, speciation of arsenic, selenium, chromium, and mercury in the leachates is being determined. Through 2003, 35 samples were collected at 14 sites representing a variety of CCP types, management approaches, and source coals. Samples have been collected from leachate wells, leachate collection systems, drive-point piezometers, lysimeters, the ash/water interface at impoundments, impoundment outfalls and inlets, and seeps. Additional sampling at 23 sites has been conducted in 2004 or is planned for 2005. First-year results suggest distinct differences in the chemical composition of leachate from landfills and impoundments, and from bituminous and subbituminous coals. Concentrations of most constituents were generally higher in landfill leachate than in impoundment leachate. Sulfate, sodium, aluminum, molybdenum, vanadium, cadmium, mercury and selenium concentrations were higher in leachates for ash from subbituminous source coal. Calcium, boron, lithium, strontium, arsenic, antimony, and nickel were higher for ash from bituminous source coal. These variations will be explored in more detail when additional data from the 2004 and 2005 samples become available.

Pennsylvanian-age Morrow reservoirs are a key component of a large fluvial-deltaic system that extends across portions of Colorado, Kansas, Oklahoma, and Texas. A problem that operators have to solve in some Morrow plays in this multi-state area is that many of the fluvial channels within the Morrow interval are invisible to seismic compressional (P) waves. This P-wave imaging problem forces operators in such situations to site infill, field-extension, and exploration wells without the aid of 3-D seismic technology. The objective of this project was to develop and demonstrate seismic technology that can improve drilling success in Morrow plays. Current P-wave technology commonly results in 80-percent of Morrow exploration wells not penetrating economic reservoir facies. Studies at Colorado School of Mines have shown that some of the Morrow channels that are elusive as P-wave targets create robust shear (S) wave reflections (Rampton, 1995). These findings caused Visos Energy to conclude that exploration and field development of Morrow prospects should be done by a combination of P-wave and S-wave seismic imaging. To obtain expanded information about the P and S reflectivity of Morrow facies, 9-component vertical seismic profile (9-C VSP) data were recorded at three locations along the Morrow trend. These data …

The BAGPIPE sub-critical experiment was executed on September 26, 1998, at about 13:07 hours. A steel and fibercrete containment barrier had been built at the entrance to the U1a.101b drift at the Nevada Test Site to form the BAGPIPE zero-room. The invert of the zero-room was covered with concrete and the ribs and back were covered with about 15 cm of fibercrete. The face was left uncovered to facilitate gas bleed-off into the alluvial formation. The volume of the room was approximately 3894 ft{sup 3}. Four small experimental packages were detonated. The LLNL containment goal for the BAGPIPE experiment was to confine all special nuclear material (SNM) to the zero-room and the alluvium surrounding the zero-room. The experiment and containment objectives are discussed more fully in the BAGPIPE Containment Prospectus and the associated addendum. Alpha-particle radiation detectors outside the BAGPIPE zero-room remained at pre-shot background levels after the experiment. A large number of swipes were taken around the BAGPIPE primary containment barrier and in the diagnostics room. No evidence that any SNM was released into the tunnel complex was found and the BAGPIPE containment was considered successful.

This study identifies possible flammable gas monitoring and ventilation system alternatives to ensure adequate removal of flammable gases from the Double-Contained Receiver Tank (DCRT) primary tanks during temporary storage of small amounts of waste. The study evaluates and compares these alternatives to support closure of the Flammable Gas Unreviewed Safety Question (USQ TF-96-04330).

Yucca Mountain comprises a series of north-trending ridges composed of tuffs within the southwest Nevada volcanic field, 120 km northwest of Las Vegas, Nevada. These ridges are formed of east-dipping blocks of interbedded welded and nonwelded tuff that are offset along steep, mostly west-dipping faults that have tens to hundreds of meters of vertical separation. Yucca Mountain is currently under study as a potential site for underground storage of high-level radioactive waste, with the principle goal being the safe isolation of the waste from the accessible environment. To this end, an understanding of the behavior of ground-water flow through the mountain in the unsaturated zone and beneath the mountain in the saturated zone is critical. The percolation of water through the mountain and into the ground-water flow system beneath the potential repository site is predicated on: (1) the amount of water available at the surface as a result of the climatic conditions, (2) the hydrogeologic characteristics of the volcanic strata that compose the mountain. and (3) the hydrogeologic characteristics of the structures, particularly fault zones and fracture networks, that disrupt these strata. This paper addresses the hydrogeologic characteristics of the fault zones at Yucca Mountain, focusing primarily on the central …

A numerical ground-water flow model is being constructed for the Death Valley regional ground-water system, an area that encompasses approximately 80,000 km{sup 2} in southern Nevada and southeastern California. Effective construction and calibration of the regional-scale steady-state flow model, developed using MODFLOW-2000, is dependent upon integration of hydrogeologic data and parameter-estimation techniques. A three-dimensional hydrogeologic-framework model of the region was initially constructed to provide a conceptual model of the geometry, composition, and hydraulic properties of the materials that control the regional ground-water flow system. This framework was resampled at the scale of the flow model to define the hydrogeologic units present in each of the 15 flow-model layers. In addition, there are non-traditional types of geologic data in the hydrogeologic-framework model that are used during flow-model calibration. For each hydrogeologic unit, the spatial distribution of geologic features important to the hydrologic system is defined. The volumetric cells can be populated by various hydrogeologic data such as the hydrogeologic unit, lithology, hydraulic conductivity, faulting, tectonic features, stratigraphic or lithologic facies, porosity, and derivative data calculated from these attributes. The approach for using this arsenal of geologic data is dependent on utilizing parameter-estimation techniques available within MODFLOW-2000. The principle of parsimony is …

The U.S. Department of Energy (DOE) launched the Contract Reform Initiative in 1994 in order to improve the effectiveness and effkiency of managing major projects and programs. The intent of this initiative is to help DOE harness both technical and market forces to reduce the overall cost of accomplishing DOE's program goals. The new approach transfers greater risk to private contractors in order to develop incentives that align contractor performance with DOE's objectives. In some cases, this goal can be achieved through public-private partnerships wherein the govermhent and the contractor share risks associated with a project in a way that optimizes its economics. Generally, this requires that project risks are allocated to the party best equipped to manage and/or underwrite them. While the merits of privatization are well documented, the question of how privatized services should be financed is often debated. Given the cost of private sector equity and debt, it is difficult to ignore the lure of the government's "risk free" cost of capital. However, the source of financing for a project is an integral part of its overall risk allocation, and therefore, participation by the government as a financing source could alter the allocation of risks in the …

The QUALIT grant funded two broad categories of work: (1) Project-wide QBone engineering, instrumentation, and integration; (2) Focused workshops and measurement work relating specifically to advanced university/DOE connectivity. Significant progress has been made in both areas and, to both, QUALIT funding has been a key enabling resource. This final report summarizes the accomplishments of the QUALIT project and explains changes to the technical focus of the project that, while significant, remained true to the overall project goal: to research, test, and deploy IP layer traffic differentiation to redress congestion-related end-to-end performance problems on key university-DOE lab paths.

Phonon drag on dislocations is the dominant process which determines the flow stress of metals at elevated temperatures and at very high plastic deformation rates. The dependence of the phonon drag on pressure or density is derived using a Mie-Grueneisen equation of state. The phonon drag is shown to increase nearly linearly with temperature but to decrease with density or pressure. Numerical results are presented for its variation for shock-loaded copper and aluminum. In these cases, density and temperature increase simultaneously, resulting in a more modest net increase in the dislocation drag coefficient. Nevertheless, phonon drag increases by more than an order of magnitude during shock deformations which approach melting. Since the dependencies of elastic moduli and of the phonon drag coefficient on pressure and temperature are fundamentally different, the effect of pressure on the constitutive law for plastic deformation can not simply be accounted for by its effect on the elastic shear modulus.

A letter report issued by the General Accounting Office with an abstract that begins "The Nuclear Regulatory Commission (NRC) has decided to move its technical training center from Chattanooga, Tennessee, to near its headquarters in Rockville, Maryland. The relocation is intended to improve the effectiveness and efficiency of the agency's operations. The center provides diverse training curricula on such topics as nuclear power plant technology augmented by training on simulators, risk assessment, radiation protection, and regulatory skills. NRC used a reasonable methodology to determine the costs of relocating its facility. It considered costs related to staff salaries, travel costs for center participants, and lease payments. However, NRC used several assumptions that, if changed, would affect the cost of the move. For example, a change in the number of staff who would relocate would have an impact on costs. According to NRC, the objective of the move was not to minimize the cost of operating the center but rather to improve the effectiveness and efficiency of the agency's operations. NRC believes that the move would yield many benefits, including greater access to training facilities by its headquarters staff and frequent use of simulators in investigations. NRC needs to resolve several issues …

A letter report issued by the General Accounting Office with an abstract that begins "This is a follow-on to GAO's report on its audit of the Internal Revenue Service's (IRS) fiscal year 2000 financial statements. Many of the issues raised in this report have persisted for years. IRS believes that the solution to many of these issues may lie in systems modernization. IRS plans to implement a new financial system that includes a cost accounting module as well as integrated administrative and custodial general ledgers that are supported by subsidiary ledgers containing the transactional details for key accounts, such as taxes receivable and property and equipment. IRS continues to make progress in addressing its financial management challenges. The strong commitment by IRS senior management to financial management reform has played a crucial role in the agency's progress so far and is critical for future improvements. IRS has developed many workaround processes that allowed it to produce reliable financial statements for fiscal year 2000. However, these processes take considerable time, effort, and expense and do not fix many of the fundamental financial management issues that continue to plague IRS."

Report presenting an investigation of a model of the Convair B-58 airplane weapons system in the transonic tunnel for a range of Mach and Reynolds numbers. Results regarding drag characteristics, lift-curve slope, and longitudinal stability parameter are provided.

"An investigation of an NACA submerged air intake was conducted on a full-scale model of a fighter-type airplane. This study was made to determine the large-scale aerodynamic characteristics of a submerged air intake proposed as the result of small-scale tests and to compare the pressure-recovery characteristics of the large- and small-scale installations. Additional tests were made to determine the effect on pressure recovery of a systematic variation of ramp divergence" (p. 1).

Memorandum presenting an investigation made at a Mach number of 1.93 to determine lift, drag, pitching-moment, and average downwash characteristics of several missile configurations. Five configurations with rectangular wings and tails of various spans were tested; each of the configurations had two locations of the wing relative to the tail.

A summary of the results of wind-tunnel tests to determine the high-speed aerodynamic characteristics of six model wings having NACA 65sub1-series sections is presented in this report. The 8-percent-thick wings were superior to the 10-percent and 12-percent-thick wings from the standpoint of power economy during level flight for Mach numbers above 0.76. However, airplanes that are to fly at Mach numbers below 0.76 will gain aerodynamically if the percentage thickness of the wing and the aspect ratio are both increased. The lift-curve slopes for the 8-percent-thick wings at 0.85 Mach number were roughly twice their low-speed values.
