Audit of controls over Superconducting Super Collider Laboratory subcontractor expenditures (open access)

Audit of controls over Superconducting Super Collider Laboratory subcontractor expenditures

In January 1989 the Department of Energy contracted with Universities Research Association, Inc. to design, construct, manage, operate, and maintain the Superconducting Super Collider Laboratory. Through Fiscal Year 1992, costs for subcontractor goods and services accounted for about 75 percent of the Superconducting Super Collider Laboratory expenditures. The Office of Inspector General evaluated the adequacy of controls in place to ensure that subcontractor costs were reasonable, as required by the contract. The following conclusions were drawn from the audit. The Superconducting Super Collider Laboratory did not consistently exercise prudent business judgment in making subcontractor expenditures. As a result, $60 million in expenditures already made and $128 million planned with commercial subcontractors were, in the authors opinion, unnecessary, excessive, or represented uncontrolled growth. The audit also found inadequate justifications, accountability, and cost controls over $143 million in expenditures made and $47 million planned with other Department of Energy laboratories. Improvements were needed in subcontract administration and internal controls, including appropriate audit coverage of the subcontracts. In addition, Department of Energy guidance concerning procurement actions between the laboratories needed to be established.

The Coal Reburning for Cyclone Boiler NO{sub x} Control Demonstration project progress for July, August and September 1993 is identified in this 14th quarterly report and pertains to the activities on draft Final Report Preparation. The project involves retrofitting/testing the reburning technology at Wisconsin Power & Light`s 100 MW, Nelson Dewey Unit {number_sign}2 in Cassville, Wisconsin to determine the commercial applicability of this technology to reduce NO{sub x} emission levels. Phase III - Operation and Disposition activities emphasized preparation of the final report. A draft has been completed and it was provided to DOE/PETC in September for review and comment. The preliminary results of the hazardous air pollutant (HAP) testing indicate no major impact of reburn on volatile organics emissions. HAP results were completed and reported by Acurex in July, 1993.

Detection and Assessment of Aircraft Corrosion (open access)

Detection and Assessment of Aircraft Corrosion

The detection and assessment of existing corrosion, or the onset thereof, in aircraft structures, related systems and components is of major concern to the United States aviation community. In this work several types of ion- and photon-beam analytical techniques were applied to the detection and assessment of corrosion. A method of laboratory classification of surface corrosion, and the identification of a corrosion preventative compound (CPC)applied on skin material removed from aircraft structures was developed. The results of this research will be useful in the development of instrumentation and inspection techniques to detect and assess corrosion. These techniques also will be useful in studying the mechanisms and efficacy of current and future CPCs. Developed instrumentation and inspection techniques have enormous potential for commercial and military application in many areas, including the transportation, nuclear, petroleum, and building sectors.

Development and testing of industrial scale coal fired combustion systems, Phase 3. Sixth quarterly technical progress report, April 1, 1993--June 30, 1993

The most significant effort in the quarter was the completion of the conversion of the exit nozzle from adiabatic operation to air cooled operation. This conversion was implemented midway in the task 2 test effort, and the final two tests in task 2 were with the cooled nozzle. It performed as per design. The second significant result was the successful implementation of a computer controlled combustor wall cooling procedure. The hot side combustor liner temperature can now be maintained within a narrow range of less than 5OF at the nominal wall temperature of 2000F. This is an essential requirement for long term durability of the combustor wall. The first tests with the computer control system were implemented in June 1993. A third development in this period was the decision to replace the coal feeder that had been in use since coal fired operation began in late 1987. Since that time, this commercial device has been modified numerous times in order to achieve uniform coal feed. Uniform feed was achieved in 1991. However, the feeder operation was not sufficiently reliable for commercial use. The new feeder has the same design as the sorbent feeders that have been successfully used since 1987. …

DOE In Situ Remediation Integrated Program. In situ manipulation technologies subprogram plan

The In Situ Remediation Integrated Program (ISRP) supports and manages a balanced portfolio of applied research and development activities in support of DOE environmental restoration and waste management needs. ISRP technologies are being developed in four areas: containment, chemical and physical treatment, in situ bioremediation, and in situ manipulation (including electrokinetics). the focus of containment is to provide mechanisms to stop contaminant migration through the subsurface. In situ bioremediation and chemical and physical treatment both aim to destroy or eliminate contaminants in groundwater and soils. In situ manipulation (ISM) provides mechanisms to access contaminants or introduce treatment agents into the soil, and includes other technologies necessary to support the implementation of ISR methods. Descriptions of each major program area are provided to set the technical context of the ISM subprogram. Typical ISM needs for major areas of in situ remediation research and development are identified.

Enhancing the use of coals by gas reburning-sorbent injection (open access)

Enhancing the use of coals by gas reburning-sorbent injection

The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO[sub x]) and sulfur (SO[sub x]) on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. The specific objectives are to demonstrate reductions of 60 percent in NO[sub x] and 50 percent in SO[sub x] emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO[sub x] is converted to N[sub 2]. The combustion process is completed by overfire air addition. SO[sub x] emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO[sub x] as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting, (2) Construction and Startup, and (3) Operation, Data Collection, Reporting and Disposition: Technology transfer to industry is accomplished …

Ethanol and Clean Air: The "Reg-Neg" Controversy and Subsequent Events

The Clean Air Act Amendments (CAAA), enacted in 1990, called for cleaner automotive fuels in order to upgrade air quality. This appeared to provide new market potential for ethanol, which is obtained from corn grown in the midwestern United States, and which is already in large-scale use in a blend of ten percent ethanol to ninety percent gasoline. The CAAA left specific details of the clean fuels program to be worked out by the Environmental Protection Agency (EPA), in consultation with the interested parties.

Final vegetative cover for closed waste sites (open access)

Final vegetative cover for closed waste sites

Low-level, hazardous, and mixed waste disposal sites normally require some form of plant material to prevent erosion of the final closure cap. Waste disposal sites are closed and capped in a complex scientific manner to minimize water infiltration and percolation into and through the waste material. Turf type grasses are currently being used as an interim vegetative cover for most sites. This coverage allows for required monitoring of the closure cap for settlement and maintenance activities. The purpose of this five year study was to evaluate plant materials for use on wastes sites after the post-closure care period that are quickly and easily established and economically maintained, retard water infiltration, provide maximum year-round evapotranspiration, are ecologically acceptable and do not harm the closure cap. The results of the study suggest that two species of bamboo (Phyllostachys (P.) bissetii and P. rubromarginata) can be utilized to provide long lived, low maintenance, climax vegetation for the waste sites after surveillance and maintenance requirements have ceased.

FORTE log periodic antenna. Phase 1, Final report (open access)

FORTE log periodic antenna. Phase 1, Final report

This report summarizes the results of ABLE`s design study of the FORTE deployable log periodic antenna. The resulting Baseline Design of the antenna is the basis for ABLE`s proposal for Phase II of this program. ABLE`s approach to meeting the requirements is to use a coilable ABLE mast as the deployable structure ``backbone`` of the antenna and to use deployable tubes for. the log periodic dipole elements of the antenna. This general approach was adopted at the outset of the Phase I Design Study. The remainder of the study was devoted to detailed design and analysis to properly size these types of mast and antenna elements and to design their deployment mechanisms. Demonstration models of the mast and antenna element deployer were fabricated as part of Phase I study. The study showed that ABLE`s design approach is feasible and can meet all the specified design requirements except the mass limit of 13.5 kg. Results of the design and analysis studies are summarized in this report. The mast and dipole element deployer are to be demonstrated to LANL personnel at the conclusion of this Phase I study.

The generalized Erlangen program and setting a geometry for four- dimensional conformal fields

This is the text of a talk at the International Symposium on ``Mathematical Physics towards the XXI Century`` held in March 1993 at Beersheva, Israel. In the first part we attempt to summarize XXth Century Physics, in the light of Kelvin`s 1900 speech ``Dark Clouds over XIXth Century Physics.`` Contrary to what is usually said, Kelvin predicted that the ``clouds`` (relativity and quantum mechanics) would revolutionize physics and that one hundred years might be needed to harmonize them with classical physics. Quantum Gravity can be considered as a leftover from Kelvin`s program -- so are the problems with the interpretation of quantum mechanics. At the end of the XXth Century, the Standard Model is the new panoramic synthesis, drawn in gauge-geometric lines -- realizing the Erlangen program beyond F. Klein`s expectations. The hierarchy problem and the smallness of the cosmological constant are our ``clouds``, generations and the Higgs sector are to us what radioactivity was in 1900. In the second part we describe Metric-Affine spacetimes. We construct the Noether machinery and provide expressions for the conserved energy and hypermomentum. Superimposing conformal invariance over the affine structure induces the Virasoro-like infinite constraining algebra of diffeomorphisms, applied with constant parameters and opening …

High efficiency shale oil recovery (open access)

High efficiency shale oil recovery

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical conditions (heating, mixing, pyrolysis, oxidation) exist in both systems.The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed this quarter. (1) Twelve pyrolysis runs were made on five different oil shales. …

ICRF heating and current drive in TFTR supershot plasmas: Data analysis and interpretation of ICRF/edge interactions. Research Progress report

The relevance of rf-sheath-plasma interactions to ICRF operation in TFTR has been studied. Screen-screen and screen-limiter rf sheaths have been identified and analyzed for the old and new Bay M geometries on TFIR, including sheath voltages driven by both feeders and the central antenna conductor. Calculations have been carried out to determine the effects of ICRF on edge transport (profile flattening by E {times} B convection), impurity influx ({delta}Z{sub eff}) and edge electron heating (FS glow phenomena) as a function of edge plasma parameters, rf power and antenna phasing. It was found that many of the experimentally observed ICRF-edge plasma interactions on TFIR are consistent with the predictions of rf sheath theory.
