Because the TEDF does not have any treatment or retention capacity, strict control at the generator interface is essential to operate the TEDF in compliance with good engineering practices, Hanford site requirements, and the 216 Discharge Permit. The information in the Interface Control Document (ICD) forms the basis of understanding between all parties involved in the TEDF; DOE, WHC, and the generating facilities. The ICD defines the controlling document hierarchy; LEF, and generator responsibilities; monitoring and sampling requirements; and specifies the TEDF/Generator Interface points.

Since 1987, Westinghouse Hanford Company has been a major contractor to the US Department of Energy, Richland Operations Office and has served as co-operator of the 300 Area Process Trenches, the waste management unit addressed in this closure plan. For the purposes of the Resource Conservation and Recovery Act, Westinghouse Hanford Company is identified as ``co-operator.`` The 300 Area Process Trenches Closure Plan (Revision 0) consists of a Resource Conservation and Recovery Act Part A Dangerous Waste Permit Application, Form 3 and a Resource Conservation and Recovery Act Closure Plan. An explanation of the Part A Permit Application, Form 3 submitted with this document is provided at the beginning of the Part A Section. The closure plan consists of nine chapters and six appendices. The 300 Area Process Trenches received dangerous waste discharges from research and development laboratories in the 300 Area and from fuels fabrication processes. This waste consisted of state-only toxic (WT02), corrosive (D002), chromium (D007), spent halogenated solvents (F001, F002, and F003), and spent nonhalogented solvent (F005). Accurate records are unavailable concerning the amount of dangerous waste discharged to the trenches. The estimated annual quantity of waste (item IV.B) reflects the total quantity of both regulated and …

This report was prepared to discuss the alternatives available for removing the 300 Area overhead signal cable system. This system, installed in 1969, has been used for various monitoring and communication signaling needs throughout the 300 Area. Over the years this cabling system has deteriorated, has been continually reconfigured, and has been poorly documented to the point of nonreliability. The first step was to look at the systems utilizing the overhead signal cable that are still required for operation. Of the ten systems that once operated via the signal cable, only five are still required; the civil defense evacuation alarms, the public address (PA) system, the criticality alarms, the Pacific Northwest Laboratory Facilities Management Control System (FMCS), and the 384 annunciator panel. Of these five, the criticality alarms and the FMCS have been dealt with under other proposals. Therefore, this study focused on the alternatives available for the remaining three systems (evacuation alarms, PA system, and 384 panel) plus the accountability aid phones. Once the systems to be discussed were determined, then three alternatives for providing the signaling pathway were examined for each system: (1) re-wire using underground communication ducts, (2) use the Integrated Voice/Data Telecommunications System (IVDTS) already installed …

Alternative Remedial Technologies, Inc. (ART) was selected in a competitive selection process to conduct a pilot study for the physical separation of soils in the North Process Pond of the 300 Area at the Hanford Site. In January 1994, ART mobilized its 15 tons-per-hour pilot plant to the site. The plant was initially staged in a commercial area to allow for pretest inspections and minor modifications. The plant was specifically designed for use as a physical separations unit and consisted of a feed hopper, wet screens, hydrocyclones, as well as settling and dewatering equipment. The plant was supported in the field with prescreening equipment, mobile generators, air compressors, and water storage tanks. The plant was moved into the surface contamination area on March 24, 1994. The testing was conducted during the period March 23, 1994 through April 13, 1994. Two soil types were treated during the testing: a natural soil contaminated with low levels of uranium, cesium, cobalt, and heavy metals, and a natural soil contaminated with a uranium carbonate material that was visually recognizable by the presence of a green sludge material in the soil matrix. The ``green`` material contained significantly higher levels of the same contaminants. Both source …

The Actinide Source Term represents the quantity of actinides that could be mobilized within WIPP brines and could migrate with the brines away from the disposal room vicinity. This document presents the various proposed methods for estimating this source term, with a particular focus on defining these methods and evaluating the defensibility of the models for mobile actinide concentrations. The conclusions reached in this document are: the 92 PA {open_quotes}expert panel{close_quotes} model for mobile actinide concentrations is not defensible; and, although it is extremely conservative, the {open_quotes}inventory limits{close_quotes} model is the only existing defensible model for the actinide source term. The model effort in progress, {open_quotes}chemical modeling of mobile actinide concentrations{close_quotes}, supported by a laboratory effort that is also in progress, is designed to provide a reasonable description of the system and be scientifically realistic and supplant the {open_quotes}Inventory limits{close_quotes} model.

The purpose of this task was to perform research for the Department of Energy (DOE) on the synthesis and characterization of additives for liquid lubricants which could lead to significant improvements in the major tribological task area of friction and wear reduction at high temperature. To this end JPL surveyed candidate precursor compounds which are soluble in liquid lubricants, synthesized the most promising of these materials, characterized them and submitted these additives to National Institute of Standards and Technology (NIST) for evaluation.

Ambient air monitoring for volatile organic compounds (VOCs) was conducted at TA-54 to characterize non-radioactive air emissions to determine if the Laboratory`s waste operations are releasing significant amounts of VOCs to the ambient environment. Samples were collected at four locations along the northern fenceline (dominant downwind side) of Areas G & L and at a background site located in Bandelier National Monument. Eight-hour integrated samples were collected in evacuated canisters during daylight hours on each of eight days during the summer of 1994, for a total of 40 samples. The samples were analyzed by gas chromatography following EPA Method TO-14 for a target list of 68 analytes. In general, about two dozen volatile organic compounds (VOCs) were identified in each sample, including those collected at the background site, but the concentration levels were very low (e.g.; < 1 to 10 ppbv). The average total non-methane hydrocarbon (TNMHC) concentration ranged from 4.3 to 22.8 ppbv at the Area G and L sites as compared with an average of 4.2 ppbv at the background site. The measured concentrations were compared with action levels developed by the New Mexico Environment Department and were well below the action levels in all cases. Methanol and …

Atomic transport of oxygen in nonstoichiometric oxides is an extremely important topic which overlaps science and technology. In many cases the diffusion of oxygen controls sintering, grain growth, and creep. High oxygen diffusivity is critical for efficient operation of many fuel cells. Additionally, oxygen diffusivities are an essential ingredient in any point defect model. Secondary Ion Mass Spectrometry (SIMS) is the most accurate modern technique to measure oxygen tracer diffusion. This paper briefly reviews the principles and applications of SIMS for the measurement of oxygen transport. Case studies are taken from recent work on ZnO and some high-temperature superconductors.

The authors investigated the decomposition of HMX or PBX-9404 as a 25% solution in DMSO by treatment with aqueous base solutions. They investigated investigated two concentrations of NaOH solutions, 40% NaOH and 2N NaOH. {sup 1}H-nmr spectroscopy was chosen to follow the decomposition by {sup 1}H-nmr spectroscopy, watching the disappearance of the -CH{sub 2}-absorbance of HMX at 6.2 ppm. The 40% NaOH solution is initially immiscible with the DMSO solution but becomes miscible as it reacts. The reaction is exothermic with recorded temperatures after mixing reaching 90{degrees}C. The mixture does foam somewhat but this can be controlled by slowing down the stirring speed. The 2N NaOH solution is miscible with the HMX/DMSO solution but upon mixing the HMX is precipitated by the water present in the base solution. The mixing of the solutions is much less exothermic and the decomposition is slower than the 40% NaOH solution so the mixture is heated at 60{degrees}C for 1h to facilitate the decomposition.

The overall objective of the project is to develop an integrated two-stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first steps, Butyribacterium methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum leads to the production of butanol and ethanol.

Our ability to interpret ecosystem response to elevated atmospheric CO{sub 2} is contingent on understanding and integrating a complex of physiological and ecological processes. However, we have a limited understanding of the combined effects of changes in plant carbon (C) allocation, microbial activity, and nitrogen (N) dynamics on the long-term response of terrestrial ecosystems to elevated CO{sub 2}. Individually, these factors are potent modifiers of C and N dynamics, and an in depth understanding of their interactions should provide insight into ecosystem-level responses to global climate change. Our research is aimed at quantifying the physiological mechanisms leading to increased fine root production, microbial biomass and rates of N cycling at elevated atmospheric CO{sub 2}. More specifically, we will experimentally manipulate soil nitrogen availability and atmospheric CO{sub 2} to understand how changes in plant resource availability influence the cycling of carbon between plants and soil microorganisms.

This report covers work completed during the seventh quarter for the project. The project consists of three tasks: the first relates to developing a database of waste volumes and disposal methods used by the industry; the second and third tasks are aimed at investigating technologies that could be used for the treatment of produced waters and developing cost estimates for those technologies. The remainder of this report describes progress related to the three tasks in the project. Overall, the majority of data analyses using information from the PED have been completed. A detailed correlation between well completions and a variety of environmental characteristics in the eight counties in Texas was developed. In terms of the treatment of produced water, much of the work in the past quarter was. focused on analyzing the costs associated with treatment using reverse osmosis and package treatment plants.

On May 26, 1994, President Clinton announced he was recommending that MFN status be extended to China for another year despite Beijing's failure to meet the human rights conditions set forward in his Executive Order of the previous year (Executive Order 12850). In addition, the President announced he was taking additional steps with respect to China, including: maintaining U.S. sanctions imposed as a result of the events in Tiananmen

The STAR electromagnetic calorimeter (EMC) will be used to measure the energy of photons and electrons from collisions of beams of particles in the RHIC accelerator under construction at Brookhaven National Laboratory. The present design is documented in the EMC Conceptual Design Report, and consists of a cylindrical barrel and two flat endcap calorimeter sections. The barrel EMC will consist of 120 modules, each subtending 6{degrees} in azimuthal angle about the beam ({phi}), and half the barrel length. Each module will be subdivided into ``towers`` of alternating scintillator and lead, which project to the nominal interaction point. There is a strong coupling between the designs for the EMC and for the conventional solenoidal magnet, which will be located immediately outside the barrel EMC. For example, the inner radius of the magnet must be minimized to lower costs and to reduce the STAR detector`s outer diameter to fit within constraints of the existing detector building. This condition requires the calorimeter modules to be just thick enough to accomplish physics goals and to support their weight with small deflections. This note describes progress in the design of the EMC support rings. Several ring designs and methods of construction have been considered. In …

The impact of particle size and chemical composition variations on determination of tank simulant moisture from near infrared (NIR) optical spectra are presented. This work shows particle size and chemical variations will impact moisture predictions from NIR spectra. However, the prediction errors can be minimized if calibration models are built with samples containing these variations as interferents. Prior work showed the NIR spectral region (1100 to 2500 nm) could be used to predict moisture content of BY-104 tank simulant with a standard error less of approximately 0.5 wt%. Particle size will increase moisture prediction error if calibration-models do not include the same particle size ranges as unknown samples. A combined particle size model with 0-420 {times}10{sup -6}m, 420-841 {times} 10{sup -6}m, and 841 {times} 10{sup -6} m-2 mm diameter particles predicted 0.59, 0.34 nd 0.23 wt% errors respectively for samples containing only these size ranges and 0.80 wt% error for a samples with all particle size ranges. Chemical composition would also increase moisture prediction error if calibration model samples chemically differ from unknown samples. For a BY-104 simulant, increases in NaOH, NaAlO{sub 2}, Na{sub 2} SiO{sub 3}, and Na{sub 3}PO{sub 4} produced moisture predictions that were lower than the actual …

In the months following China's 1989 Tiananmen Square crackdown, both the President and the Congress took a number of initiatives protesting Beijing's actions. These initiatives centered around U.S. concerns related to trade, human rights, and non-proliferation. In intervening years, the United States has periodically imposed, lifted, or waived other sanctions and concluded several trade-related agreements with China relating to these concerns. Those measures that remain in place in 1994 are detailed in the accompanying tables.
