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.

Site Management System (SMS) guidance requires a Fiscal Year Work Plan (FYWP) to be prepared for the Environmental Restoration (ER) Mission Area and all related programs.

Approximately 80 commercially available fluorescent organic compounds were studied as dopants in a polystyrene matrix for possible use in wavelength shifting (WLS) fibers. The goal was to find a new green- emitting WLS fiber which would outperform in light yield and decay time the currently available fiber doped with K-27. Therefore the fluorescent compounds of interest should exhibit the following spectroscopic characteristics in polystyrene: {lambda}{sub abs} = 400--450 nm,{lambda}{sub em} = 450--550 nm, {tau} = 3--7 ns and quantum efficiency of minimum 0.7. Polystyrene samples doped with different fluorescent compounds were prepared and characterized. Of all the compounds tested, only a series of coumarins exhibited the spectroscopic characteristics of interest. Radiation damage studies had to be performed on these samples in order to condusively determine if they were better candidates than K-27 for green WLS fibers. AU samples except those showing opacity or deep coloration were irradiated. They were, however, separated in two sets. Radiation damage set No. 20 was mainly formed by the coumarin derivatives. Radiation damage set No. 22 was based on the remaining samples. The irradiations were performed at the Phoenix Memorial Laboratory using a {sup 60}Co source. Both sets were exposed to a total dose of …

This research investigates the relationship between execution discipline and performance. The hypothesis has two parts: 1. Different execution disciplines exhibit different performance for different computations, and 2. These differences can be effectively predicted by heuristics. A machine model is developed that can vary its execution discipline. That is, the model can execute a given program using either the control-driven, data-driven or demand-driven execution discipline. This model is referred to as a ``variable-execution-discipline`` machine. The instruction set for the model is the Program Dependence Web (PDW). The first part of the hypothesis will be tested by simulating the execution of the machine model on a suite of computations, based on the Livermore Fortran Kernel (LFK) Test (a.k.a. the Livermore Loops), using all three execution disciplines. Heuristics are developed to predict relative performance. These heuristics predict (a) the execution time under each discipline for one iteration of each loop and (b) the number of iterations taken by that loop; then the heuristics use those predictions to develop a prediction for the execution of the entire loop. Similar calculations are performed for branch statements. The second part of the hypothesis will be tested by comparing the results of the simulated execution with the …

This document reports work during this quarter on the project to produce higher alcohols from synthesis gas. A set of four methanol synthesis runs was conducted. Significant catalyst deactivation was experienced, and essentially all of the oil was lost from the reactor over the course of two weeks of operation. Three screening runs of potential high temperature oil were also conducted. However, essentially no oil remained in the reactor after completion of each run. A 1%Rh/1.3%Re/Al{sub 2}O{sub 3} catalyst was prepared from Re and Rh carbonyls with the objective of obtaining intimate contact between Rh and Re atoms. The catalytic activity of this catalyst was explored. Mo was deposited on the catalyst from both molybdenum hexacarbonyl [Mo(CO){sub 6}] and (NH{sub 4}){sub 6}Mo{sub 7}O{sub 24}{center_dot}4H{sub 2}O. The catalytic activity of the molybdenum promoted catalysts was found to be the highest achieved to date under this contract.

Our 1993 third quarter report discusses the results of our work on: (1) gas-oil gravity drainage in layered media; and, (2) the influence of viscous forces on gas-oil flow in fractured porous media. For sometime, we have been working on the incorporation of reinfiltration and capillary continuity concepts in a dual-porosity model. A simple and accurate technique has been developed for this purpose. The experiments on gas-oil gravity drainage in layered media are intended to: (1) verify our theoretical analysis; (2) provide more insight; and, (3) provide a guide for the simulation of gas-oil gravity drainage at field scale. On the first objective, the experiments confirm that gas-oil gravity drainage could result in a downward gas fingering phenomenon. Without capillary pressure, downward gas fingering could not realize. The experiments also show that drainage from a less permeable layer would be an extremely slow process. This is similar to the drainage performance of matrix blocks in fractured porous media. Apparently, relative permeability to gas (i.e. gas mobility) may be important for flow in layered porous media. The project on the effect of viscous forces on gas-oil displacement in fractured porous media has taken longer than anticipated. For the first time, in …

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.

Finally, the report also surveys Aristide's rule and his subsequent overthrow by the Haitian military.

This Technical Report is intended to communicate the findings from the latest phase of New Waste Transfer Facility (NWTF) transfer pump testing. These tests have identified causes for the high pump vibrations that have been observed during previous phases of transfer pump startup testing, and have led to recommendations for resolving the vibration problem. The paper describes the problem, the test methodology, observations, and recommend actions to correct the vibration problem.

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.

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 …

Work on this coke oven gas cleaning demonstration project (CCT-II) this quarter has been focused on Phase IIB tasks, and include engineering, procurement, construction, and training. Additionally, plans for changes in the operating schedule of the coke plant that affect the demonstration project are described. Engineering efforts are nearly complete. Remaining to be finalized is an assessment of electrical heat tracing/insulation needs for pipe lines, assessment of fire protection requirements, and instrument modifications. Procurement of all major equipment items is complete, except for possible additions to fire fighting capabilities. Major focus is on expediting pipe and structural steel to the project site. Civil construction is complete except for minor pads and bases as required for pipe supports, etc. Erection of the hydrogen sulfide and ammonia scrubber vessels is complete. Installation of scrubber vessel internals is underway. A subcontractor has been retained to develop a computerized program for operations and maintenance training for the coke oven gas treatment plant. Recent developments in the coke plant operating plans will result in reductions in the rate of production of coke oven gas to be processed in the demonstration project.

Chemical processing of irradiated reactor elements at the Savannah River Site separates uranium, plutonium and fission products; fission products and process-added chemicals are mixed with an excess of NaOH and discharged as a basic slurry into large underground tanks for temporary storage. The slurry is composed of base-insoluble solids that settle to the bottom of the tank; the liquid supemate contains a mixture of base-soluble chemicals--nitrates, nitrites aluminate, sulfate, etc. To conserve space in the waste tanks, the supemate is concentrated by evaporation. As the evaporation proceeds, the solubilities of some components are exceeded, and these species crystallize from solution. Normally, these components are soluble in the hot solution discharged from the waste tank evaporator and do not crystallize until the solution cools. However, concern was aroused at West Valley over the possibility that plutonium would precipitate and accumulate in the evaporator, conceivably to the point that a nuclear accident was possible. There is also a concern at SRS from evaporation of sludge washes, which arise from washing the base-insoluble solids ({open_quote}sludge{close_quote}) with ca. 1M NaOH to reduce the Al and S0{sub 4}{sup {minus}2} content. The sludge washes of necessity extract a low level of Pu from the sludge and …

A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the fifth quarter of work. The major accomplishments were: (1) Completion of coal liquefaction autoclave reactor runs and related analysis with Illinois no. 6 coal at 400{degrees}C with and without surfactant and/or catalyst at pressures of 1700 psig; (2) A literature search into the effect that lignin has in the coprocessing of coal; and (3) Presentation of a report summarizing the first year of work on this task at the Annual Liquefaction Contractors Review Conference. Results from this quarter show that lignosulfonate surfactant continues to increase overall MAF conversion of Illinois no. 6 coal at temperatures up to 400{degrees}C and produces an improvement in light boiling fraction distillate over the base case of no surfactant addition.

This report investigates whether DOE activities could benefit from greater and more consistent access to intelligence information on selected entities with foreign interests. It does not cover dual-use and munition commodities. The investigation determined what information was available from the national intelligence community and law enforcement agencies that would have prevented DOE contracts with selected entities if the information had been available and regulations regarding contracts with selected entities had been enforced.

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. …

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.

A serious consideration of laser power beaming for satellite applications appears to have grown out of a NASA mission analysis for transmitting power to lunar bases during the two week dark period. System analyses showed that laser power beaming to the moon in conjunction with efficient, large area solar cell collection panels, were an attractive alternative to other schemes such as battery storage and nuclear generators, largely because of the high space transportation costs. The primary difficulty with this scheme is the need for very high average power visible lasers. One system study indicated that lasers in excess of 10 MW at a wavelength of approximately 850 nm were required. Although such lasers systems have received much attention for military applications, their realization is still a long term goal.

In bombardments of {sup 248}Cm with {sup 22}Ne the authors discovered two new isotopes, {sup 265}106 and {sup 266}106, by establishing genetic links between {alpha} decays of the 106 nuclides and SF or {alpha} decays of the daughter (grand-daughter) nuclides. For {sup 266}106 they measured E{sub {alpha}}=8.62{+-}0.06 MeV followed by the SF decay of {sup 262}104 for which they measured a half-life value of 1.2{sup +1.0}{sub {minus}0.5} s. For {sup 265}106 they measured E{sub {alpha}}=8.82{+-}0.06 MeV. They estimated {alpha} half-lives of 10-30 s for {sup 266}106 and 2-30 s for {sup 265}106 with SF branches of {approximately}50% or less. The decay properties of {sup 266}106 indicate a large enhancement in the SF stability of this N=160 nuclide and confirm the existence of the predicted neutron-deformed shell N=162.
