This Engineering Task Plan outlines the remaining work to be completed for the BX/BY Instrument Air upgrade. Initial work efforts were guided by Engineering Work Plan, ``BX-BY Compressor Upgrade`` dated 1-25-93 (see Attachment A) which is provided for information. The overall engineering task is to provide a permanent replacement for the instrument air supply system for the 241-BX/BY Tank Farms. The existing system consists of a 25 horsepower Worthington non-lube compressor and an Oriad air dryer. The existing equipment is dated, requires high maintenance and is located in a contaminated zone making it unusable. The BX/BY instrument air replacement unit will be one of the 100 SCFM generic air stations. This station will be permanently sited with the addition of drawing changes to provide a concrete foundation, air piping to existing lines and electrical power supply tie-ins.

This document provides the technical baseline for retrieval of waste from ten double-shell tanks in the SY, AN, AP, AW, AY, and AZ tank farms. In order to retrieve waste from these tanks, systems are needed to mix the sludge with the supernate and pump the waste mixture from the tank. For 101-SY, the existing mitigation pump will be used to mix the waste and Project W-211 will provide for waste removal. The retrieval scope for the other nine tanks includes both the waste mixing and removal functions.

Programming parallel computers for performance is a difficult task that requires careful attention to both single-node performance and data exchange between processors. This paper discusses some of the sources of poor performance, ways to identify them in an application, and a few ways to address these issues.

This CSER qualifies use of a 5% borated, lead foil lined polyethylene 1 inch annulus as a bucket and in a small carrier to move sealed containers of plutonium. The containers are Oversize Cans or smaller containing plutonium limited in mass and H/Pu ratio by PFP storage and transportation CPS`s. These ALARA shielding units reduce personnel exposure to the radiation from the containers as they are moved for assay and other required activities.

This engineering note documents a communication link between the D0 cryo/gas control system and the D0 physics data acquisition computer system. This note is being written well after the work has been completed, in order to document this communications link, and to satisfy needs of planned upgrades. These upgrades are the D0 Super Conducting Solenoid, VLPC system, and Silicon Detector System. The D0 cryo/gas control system is a Programmable Logic Controller based process control system. It is responsible for controlling many of the physical parameters of the D0 experiment, such as Calorimeter cooling, vacuum, Instrument air, TRD gas pressures and flows, W AMUS pressures and flows, SAMUS pressure and flows, etc. It works independent of the Physics DAQ system. There is a need for the Physics DAQ system to record some of these process values with the D0 physics data. This process data will later be used to calibrate certain features of the Physics data during reconstruction. The process data is also used to interlock (via the Physics DAQ system) some of the other D0 systems such as the TRD high voltage system. Some of the Process data values will be continuously monitored and will stop the Physics data taking …

The purpose of this document is to provide the design support information for the Vertical Fuel Handling Tools, developed for the removal of N Reactor fuel elements from their storage canisters in the K Basins storage pool and insertion into the Single Fuel Element Can for subsequent shipment to a Hot Cell for examination. Examination of these N Reactor fuel elements is part of the overall characterization effort. These new hand tools are required since previous fuel movement has involved grasping the fuel in a horizontal position. These tools are required to lift an element vertically from the storage canister. Additionally, a Mark II storage canister Lip Seal Protector was designed and fabricated for use during fuel retrieval. This device was required to prevent damage to the canister lip should a fuel element accidentally be dropped during its retrieval, using the handling tools. Supporting documentation for this device is included in this document.

The objective of this project is to retrofit the previously developed High Efficiency Advanced Coal Combustor (HEACC) to a standard gas/oil designed industrial boiler to assess the technical and economic viability of displacing premium fuels with microfine coal. During this reporting period, activities included completing the ``Task 3 Topical Report.`` The report is being reviewed internally by the ABB CE project team. Overall, all the program goals were met except carbon conversion efficiency. Based on all the results obtained to date the ABB CE/Penn State team believes that conducting the 1000 hr demonstration (Task 5) is warranted. Since, Penn State has planned to conduct long term combustion tests on micronized coal and coal-water fuels for other DOE-funded Projects during the first quarter of 1995, the demonstration phase (Task 5) of the subject program is tentatively scheduled to begin in June 1995, pending DOE approval. Work continued under Task 4.0 to complete the ``Commercialization Plan`` with ABB CE`s cognizant Business Unit. To address the lower combustion efficiency than the original project goal (95% vs 98%) during Task 3, the data were evaluated in-detail to understand which of the key parameters might be adjusted to achieve the desired burnout. To identify reasons …

Several cryogenic targets must be injected each second into a reaction chamber. Required target speed is about 100 m/s. Required accuracy of the driver beams on target is a few hundred micrometers. Fuel strength is calculated to allow acceleration in excess of 10,000 m/s{sup 2} if the fuel temperature is less than 17 K. A 0.1 {mu}m thick dual membrane will allow nearly 2,000 m/s{sup 2} acceleration. Acceleration is gradually increased and decreased over a few membrane oscillation periods (a few ms), to avoid added stress from vibrations which could otherwise cause a factor of two decrease in allowed acceleration. Movable shielding allows multiple targets to be in flight toward the reaction chamber at once while minimizing neutron heating of subsequent targets. The use of multiple injectors is recommended for redundancy which increases availability and allows a higher pulse rate. Gas gun, rail gun, induction accelerator, and electrostatic accelerator target injection devices are studied, and compared. A gas gun is the preferred device for indirect-drive targets due to its simplicity and proven reliability. With the gas gun, the amount of gas required for each target (about 10 to 100 mg) is acceptable. A revolver loading mechanism is recommended with a …

The main goal of the ITER Conductor Testing Program is to validate the design and the fabrication process of the CICC (Cable-In-Conduit Conductor) and its joints, in full-size samples. For testing large-scale cable-in-conduit conductors, several practical experimental techniques have been developed to specifically address the issues of conductor stability. The following described techniques enable experimentalists to quantify the effects and thus provide useful tools to improve the conductor performance in magnet applications. In this paper, the authors, present two experimental techniques: (a) stability margin calibration and (b) current distribution. Both are much needed in the laboratory for testing the conductor stability.

This documents Phase 1 determinations on sampler induced bias for four sampler types used in tank characterization. Each sampler, grab sampler or bottle-on-a-string, auger sampler, sludge sampler and universal sampler, is briefly discussed and their physical limits noted. Phase 2 of this document will define additional testing and analysis to further define Sampler Bias.

The authors consider the problem of using the information from various time series, each one characterizing a different physical quantity, to predict the future state of the system and, based on that information, to detect and classify anomalous events. They stress the application of principal components analysis (PCA) to analyze and combine data from different sensors. They construct both linear and nonlinear predictors. In particular, for linear prediction the authors use the least-mean-square (LMS) algorithm and for nonlinear prediction they use both backpropagation (BP) networks and fuzzy predictors (FP). As an application, they consider the prediction of gamma counts from past values of electron and gamma counts recorded by the instruments of a high altitude satellite.

A series of mixing tests were performed to identify the range of liquid levels and overall dispersed (organic) concentrations where a constant agitator speed representative of plant operations could eliminate a separate organic layer on the liquid surface. The test runs were made in a transparent, baffled, paddle-agitated, Plexiglas vessel which was fitted with three concentric cooling coils. A visual observation method was used without taking any samples to determine the quality of mixing in the agitated vessel as a function of the total liquid level in the vessel at a given dispersed phase concentration (8 vol %) and various organic phase concentrations at a constant water content. The observations have determined that gross uniform dispersion throughout a canyon tank can be achieved with the current plant impeller speed when the total liquid level is near the vicinity of the second (top) impeller. These observations were recorded in a video tape.

The Federal Energy Regulatory Commission`s (Commission) mission is to oversee America`s natural gas and oil pipeline transportation, electric utility, and hydroelectric power industries to ensure that consumers receive adequate energy supplies at just and reasonable rates. To carry out this mission, the Commission issues regulations covering the accounting, reporting, and rate-making requirements of the regulated utility companies. The Commission`s Office of Chief Accountant performs financial related audits at companies to ensure compliance with these regulations. The purpose of this audit was to evaluate the office of Chief Accountant`s audit performance. Specifically, the objectives were to determine if the most appropriate audit approach was used and if a quality assurance process was in place to ensure reports were accurate and supported by the working papers.

Deng Xiaoping's death will create a vacuum at the center of political power in China. Successor leaders will decide whether to continue the recent collective leadership decision-making processes and policy emphasis on political stability and economic reform; or to press for political power in a search for personal or policy advantage. A struggle for political power in Beijing would complicate an already difficult set of problems of governance caused by rapid economic growth, social change, realignment of central and local power arrangements and other factors. Nevertheless, there are important reasons why China may effectively work its way through the leadership transition.

A nitrogen phase separator is recommended on the liquid supply line at the helium refrigerator plant. This engineering note documents the calculations done to reach that conclusion. The steady state liquid nitrogen consumption rate for the refrigerator, VLPC and solenoid systems is about 30 gal/hr. The estimated heat leak for the piping run to the refrigerator location is 50 watts. The calculated quality at the refrigerator was 0.032. Given this quality, a two phase flow model based on Lockhart-Martinelli and also incorporating Baker diagram nomenclature was run on TK solver. The result of this program was that without the use of a phase separator we could expect a slug flow pattern with a volume fraction of gas of 65%. Based on this, I recommend that we use a phase separator to siphon off the gas before the nitrogen is sent to a standard saver type subcooler. Including the phase separator will help ensure proper operation of the subcooler. The subcooler will help us attempt to deliver single phase liquid to the nitrogen control valves.

On July 29, 1994, the United States signed the Agreement Relating to the Implementation of Part XI of the United Nations Convention on the Law of the Sea of 10 December 1982. This agreement substantially reforms the seabed mining provisions of the 1982 Convention, which the United States found objectionable. In signing the Agreement, President Clinton accepted provisional application of it which enables the United States to participate in the International Seabed Authority (ISA) and its organs and bodies. On November 16, 1994, the U.N. Law of the Sea Convention entered into force without accession by the United States.The treaty document was referred to the Senate Committee on Foreign Relations late in the 103d Congress and awaits committee action in the 104th Congress.
