The Hydrogen Mitigation Mixing Pump (HMMP) in Tank 241-SY-101 will need to be removed at some point. At that time, the HMMP will be placed in a shipping container and transferred to a designated onsite location depending on waste classification. This report shows how the radioactive material content of shipping container will be determined. Once the radioactive material loading is known, the waste classification of the container may be determined in accordance with established procedures.

A Distributive Process Control system was purchased by Project B-534. This computer-based control system, called the Monitor and Control System (MCS), was installed in the 242-A Evaporator located in the 200 East Area. The purpose of the MCS is to monitor and control the Evaporator and Monitor a number of alarms and other signals from various Tank Farm facilities. Applications software for the MCS was developed by the Waste Treatment System Engineering Group of Westinghouse. This document describes the Device Logic for this system.

The 13 containers from K Basins hold one cartridge filter each. The filters removed solids from the K Basins water before the water went to air-cooled chillers. The filters are about 75.7 cm (30 inches) in diameter and 86 cm (34 inches) tall (based on an outline on drawing H-1-34709 (Reference 1)). This is a volume of 388 liters. Drawing H-1-34709 (Reference 1) shows the configuration of the concreted 122 cm (48 inch) diameter culvert cut to 124 cm (49 inches) long and shows the imbedded steel. The culvert is 0.35 cm (0.138 inches) thick and has a volume of 1450 liters. There are four 127 cm (50 inch) long 2 inch by 3/4 inch steel bars and reinforcing steel in the container. The culvert and four bars weigh 169.6 kg. The cylindrical culvert is oriented vertically with an 11 gauge bottom plate welded on and then filled to 15 cm (6 inches) with grout. The cartridge filter, bagged in 20 mill plastic (Reference 2), is then placed in the center of the culvert and the culvert is filled with concrete. Four of the 13 culverts were then put vertically into 152 cm (5 foot) diameter culverts about 61 cm …

The PHENIX [Photon Electron New Heavy Ion Experiment] Detector is one of two large detectors presently under construction for RHIC (Relativistic Heavy Ion Collider) located at Brookhaven National Laboratory. Its primary goal is to detect a new phase of matter; the quark-gluon plasma. In order to achieve this objective, the PHENIX Detector utilizes a complex magnet subsystem which is comprised of two large magnets identified as the Central Magnet (CM) and the Muon Magnet (MM). Muon Identifier steel is also included as part of this package. The entire magnet subsystem stands over 10 meters tall and weighs in excess of 1900 tons (see Fig. 1). Magnet size alone provided many technical challenges throughout the design and fabrication of the project. In addition, interaction with foreign collaborators provided the authors with new areas to address and problems to solve. Russian collaborators would fabricate a large fraction of the steel required and Japanese collaborators would supply the first coil. This paper will describe the overall design of the PHENIX magnet subsystem and discuss its present fabrication status.

{open_quotes}Evaluation Engineering and Development of Advanced Cyclone Processes{close_quotes} is one of the DOE-PETC sponsored advanced coal cleaning projects, which share a number of specific goals. These goals are to produce a 6% ash product, reject 85% of the parent coal`s pyritic sulfur, recover 85% of the parent coal`s Btu value, and provide products that are less than 30% moisture. The process in this project, as the name implies, relies on a cyclone or cyclonic separator to achieve physical beneficiation based on the gravimetric differences between clean coal and its impurities. Just as important as the cyclonic separator, if not more so, is the selection of a parting liquid or medium for use in the separator. Selection of a separating medium is regarded as a significant portion of the project because it has a profound impact on the required unit operations, the performance of the separator, and economics of the process. The choice of medium especially influences selection of media recovery system(s), and the characteristics of clean coal and refuse products. Since medium selection is such an important aspect of the project, portions of the project are dedicated to the study, evaluation, and selection of the most desirable medium. Though separators …

This research considers the mean squared error (MSE) incurred in estimating an idealized earth`s global average temperature with a finite network of point gauges distributed optimally over the globe. The construction of a linear smoothing filter is considered for estimating the forced part of a change in a climatological field such as the surface temperature. The filter is optimal in the sense that is suppresses the natural variability of noise relative to the forced part or signal to the maximum extent possible.

Five drums of mixed waste were accepted from LBL during FY 1994; they contain inorganic acids and compounds, as well as organic reagents and radioactive materials. This document defines the work plan for stabilization and characterization of the waste in three of these 5 drums.

DOE established policies to ensure that Cooperative Research and Development Agreements (CRADAS) enhance US competitiveness in the world economy, provide a reasonable return on resources invested, and enable successful commercialization of technologies developed. DOE`s Office of Technology Partnerships issued a General Guidance Memorandum to DOE operations offices establishing policy goals for technology transfer programs, including CRADAS. Our audit disclosed that efforts to manage CRADAs at three national laboratories did not fully achieve DOE`s policy goals outlined in the General Guidance Memorandum. Specifically, the audit showed that: (1) joint work statements did not always contain clearly defined information that allowed DOE to facilitate technology transfer or to evaluate CRADAs potential benefits; (2) CRADA statements of work did not always contain adequate documentation or address potential benefits; (3) the national laboratories reviewed did not have effective mechanisms for continuous self-appraisal or measures of overall program success; and (4) CRADA provisions did not exist to ensure an accurate evaluation of partner contributions.

The development of a three-dimensional spatially evolving compressible mixing layer is investigated numerically using a parallel implementation of Adaptive Mesh Refinement (AMR) on a Cray C-90. The parallel implementation allowed the flow to be highly resolved while significantly reducing the wall-clock runtime. A sustained computation rate of 5.3 Gigaflops including I/O was obtained for a typical production run on a 16 processor machine. A novel mixing layer configuration is investigated where a pressure mismatch is maintained between the two inlet streams. In addition, the sonic character of the two streams is sufficiently different so that the pressure relief wave is trapped in the high speed stream. The trapped wave forces the mixing layer to form a characteristic cellular pattern. The cellular structure introduces curvature into the mixing layer that excites centrifugal instabilities characterized by large-scale counter-rotating vortical pairs embedded within the mixing layer. These are the dominant feature of the flow. Visualizations of these structures in cross-section show the pumping action which lifts dense fluid up into light gas. This effect has a strong impact on mixing enhancement as monitored by a conserved scalar formulation. Once the large-scale structures axe well established in the flow and undergo intensification from favorable …

Progress in developing novel, rigid, monolithic adsorbent carbon fiber composites is described. Carbon fiber composites are activated using steam or CO{sub 2}, in order to produce uniform activation through the material and to control the pore structure and adsorptive properties. There is an overall shrinkage during activation, which is directly correlated with burnoff; burnoff above 40% results in fracture. Burnoffs higher than 10% does not produce any benefit for separation of CH{sub 4}-CO{sub 2} mixtures. Five samples of CFCMS have been prepared for testing as molecular sieves; all have relatively narrow pore size distributions with average pore diameters around 6A.
