The 1994 SIAM Forum examined applied mathematics in industry with a particular focus on the ingredients for a successful career. The presentations were a mix of panel discussions and individual speakers. In their presentations and discussions, members of four different panels explored: the experiences of recent graduates whose first job was in industry; the hiring process from the point of view of managers; the place of mathematics and of mathematicians in smaller firms; the insights of industrial applied mathematicians whose terminal degree is not in mathematics. Another view of careers in business, industry, and government was provided by a presentation of preliminary data from SIAM`s Mathematics in Industry (MII) project. Finally, techniques for building bridges from academia to industry were described by several experienced speakers. In spite of the diverse backgrounds of the Forum`s panelists and speakers, the central ideas they presented were strikingly similar. These common themes are outlined here. The Forum program is appended to this report.

This report describes the analysis of the surface crust samples taken from single-shell tank (SST) BY-104, suspected of containing ferrocyanide wastes. This sampling and analysis will assist in ascertaining whether there is any hazard due to combustion (burning) or explosion of these solid wastes. These characteristics are important to future efforts to characterize the salt and sludge in this type of waste tank. This report will outline the methodology and detail the results of analyses performed during the characterization of this material. All analyses were performed by Westinghouse Hanford Company at the 222-S laboratory unless stated otherwise.

A new ventilation system is being installed to serve as the K-1 primary exhauster. The existing K-1 primary exhauster will then become the backup. This ventilation system services waste tanks 241-SY-101, 102 and 103. The nominal flow rate through the ventilation system is 1,000 cfm. The new ventilation system will contain a moisture eliminator, a heater, a prefilter, two stages of HEPA filtration, an exhaust fan, a stack and stack sampling system. The purpose of this document is to serve as the design and functional requirements for the mechanical installation of the new 241-SY modular exhauster. The mechanical installation will include modifying the existing ductwork (i.e., installing a ``T`` to connect the new exhauster to the existing system), modifying the existing condensate drain lines to accommodate the new lines associated with the new exhauster, a maintenance platform near the stack of the new exhauster, guy wires and guy wire footings to support the stack of the new exhauster, as well as other miscellaneous tasks associated with the mechanical installation design effort.

In December 1994, NATO members will begin the process of debating possible criteria for new members from Central Europe. Alliance relations with Russia will be a central factor determining the outcome of the debate.

This document provides the functional design criteria required for the Phase 2 Liquid Effluent Treatment and Disposal Project, Project W-252. Project W-252 shall provide new facilities and existing facility modifications required to implement Best Available Technology/All Known, Available, and Reasonable Methods of Prevention, Control, and Treatment (BAT/AKART) for the 200 East Phase II Liquid Effluent Streams. The project will also provide a 200 East Area Phase II Effluent Collection System (PTECS) for connection to a disposal system for relevant effluent streams to which BAT/AKART has been applied. Liquid wastestreams generated in the 200 East Area are currently discharged to the soil column. Included in these wastestreams are cooling water, steam condensate, raw water, and sanitary wastewaters. It is the policy of the DOE that the use of soil columns to treat and retain radionuclides and nonradioactive contaminants be discontinued at the earliest practical time in favor of wastewater treatment and waste minimization. In 1989, the DOE entered into an interagency agreement with Ecology and EPA. This agreement is referred to as the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement). Project W-252 is one of the projects required to achieve the milestones set forth in the Tri-Party Agreement. One …

This document details the plan for the shipping of fuel samples from the K Basins to the 300 Area for characterization. The fuel characterization project will evaluate the Hanford defense production fuel (N-Reactor and Single Pass Reactor) to support interim storage, transportation and final disposition. A limited number of fuel samples will be transported to a laboratory for analysis. It is currently estimated that 20 shipments of fuel per year for approximately 3 years (could be as long as 5 years) will be transported to the laboratory for analysis. Based on the NRC certificate of compliance each shipment is limited to 500 equivalent grams of {sup 235}U. In practical terms this will limit shipments to three outer elements or two assemblies of any type of N-Reactor or SPR fuel. Case by case determination of broken fuel will be made based on the type of fuel and maximum potential fissile content.

The U.S.-Japan framework talks were initiated in July 1993. The automotive negotiations between Japan and the United States focused on sales of U.S. vehicles in Japan; sales of U.S.-made original equipment parts in Japan and to Japanese transplants in the United States; and deregulation of the market for replacement parts in Japan. An unresolved dispute over shock absorbers and other replacement parts resulted in the United States launching a formal investigation of Japanese market barriers to imported car parts under Section 301 on Oct. 1, 1994.

The purpose of this work was to provide the thermal hydraulic analysis for the Multi-Function Waste Tank Facility (MWTF) Title II design. Temperature distributions throughout the tank structure were calculated for subsequent use in the structural analysis and in the safety evaluation. Calculated temperatures of critical areas were compared to design allowables. Expected operating parameters were calculated for use in the ventilation system design and in the environmental impact documentation. The design requirements were obtained from the MWTF Functional Design Criteria (FDC). The most restrictive temperature limit given in the FDC is the 200 limit for the haunch and dome steel and concrete. The temperature limit for the rest of the primary and secondary tanks and concrete base mat and supporting pad is 250 F. Also, the waste should not be allowed to boil. The tank geometry was taken from ICF Kaiser Engineers Hanford drawing ES-W236A-Z1, Revision 1, included here in Appendix B. Heat removal rates by evaporation from the waste surface were obtained from experimental data. It is concluded that the MWTF tank cooling system will meet the design temperature limits for the design heat load of 700,000 Btu/h, even if cooling flow is lost to the annulus region, …

This plan describes the activities to be performed and the controls to be applied to the process of specifying, developing, and qualifying the data acquisition software for the Radioisotope Thermoelectric Generator (RTG) Transportation System Subsystem 143 Instrumentation and Data Acquisition System (IDAS). This plan will serve as a software quality assurance plan, a verification and validation (V and V) plan, and a configuration management plan.

The Defense Waste Processing Facility (DWPF) will be used to encapsulate high-level radioactive waste into borosilicate glass at the Savannah River Site. To ensure that the process streams will be blended in the right proportions to produce durable glass, process control analyses will be performed in a laboratory in the DWPF. The high radioactivity of DWPF samples will require that sample preparation, including dissolution and dilution of samples, be performed in shielded cells. However the final analyses will be made with instruments and spectrometers contained in unshielded fume hoods. The primary radiation concern is the exposure to y-rays from the decay of Cs-137 after samples are removed from the shielded cells. Since there are several methods available for removing Cs-137 from samples, investigations were made into removing Cs-137 from DWPF samples prior to analysis in order to reduce worker exposure. Results are presented of the efficiency of various Cs-137 removal techniques and the effects of these techniques on analytical precision and accuracy.

The Process Chemistry Laboratories were requested to support the 242-A Evaporator restart as part of the overall 222-S laboratory effort. The net purpose of these studies is to determine the characteristics of double-shell tank materials as they are processed in the evaporator. The results for the boildown study (which includes pressure and temperature versus % waste volume reduction and density of final boildown residue) supporting the 242-A Evaporator restart are reported below. The boildown was performed in a vacuum distillation apparatus with an adjustable vacuum limiting manometer and an isolatable collection graduated cylinder. The boildown was conducted over a seven hour period. The evaporation was done at 60 torr (to avoid excessive foaming and bumping of solution) for approximately half of the boildown, the pressure then being reduced to 40 torr when the reduction in solution volume allowed this to be done. Percent waste volume reduction was measured by observing the amount of condensate collected in a graduated cylinder. As the graduated cylinder became full, it was isolated from the rest of the system and the condensate removed. Pressure was set using an electronic manometer with a low pressure limiter set at the desired level. Temperature was measured using a …

Calcium metabolism in biology may be better understood by the use of {sup 41}Ca labels, although detection by accelerator mass spectrometry (AMS) is required. Methodologies for preparation of urine samples and subsequent AMS measurement were investigated. Novel attempts at preparing CaH{sub 2} were unsuccessful, but CaF{sub 2} of sufficient purity could be produced by precipitation of calcium from urine as oxalate, followed by separation of calcium by cation exchange chromatography and washing the CaF{sub 2} precipitate. The presence of some remaining impurities could be compensated for by selecting the appropriate accelerated ion charge state for AMS. The use of projectile x rays for isobar discrimination was explored as an alternative to the conventional dE/dx device.

The intent of this pamphlet is to share information with others who are interested in useful protocols for cotton cytogenetics and cytology. The protocols described are a beginning effort and they are expected to be improved. All methods, results and data given pertain to cultivar MD 51ne. We are not satisfied with our results of in situ hybridization.

High Level Waste (HLW) generated during Separations processing in the F- and H-Canyons is transferred to the Tank Farms for stage in 51 underground, million gallon storage tanks. The waste is an aqueous solution containing dissolved sodium salts and insoluble metal oxides/hydroxides. The waste solution is evaporated to reduce the volume, and the resulting saltcake and residual supernate are stored. Over the 40 year history of the Tank Farm, routine supernate sampling has been conducted in support of the primary goal of safe storage of HLW. As a result of routine and non-routine activities that are part of managing these highly radioactive wastes, secondary solid waste is generated. Radioactive contamination of over 90% of the solid waste generated is due to contact with BLW supernate or saltcake. In order to comply with the Waste Acceptance Criteria (WAC) for of solid waste in the E-Area Vaults (EAV), the quantity of certain radioisotopes must be manifested for each waste container and a declaration made of whether or not the waste is hazardous. However, solid waste is not amenable to routine analysis, this forces a reliance on analytical data from supernate samples to characterize the contamination. To provide the manifest information, process knowledge …

Mixing tests for the Multifunction Waste Tank Facility (MWTF) were conducted in 1/25 and 1/10 scale test tanks with different slurry levels, solids concentrations, different jet mixers and with simulated in-tank structures. The same test procedure was used as in the Title I program, documented in WHC-SD-W236A-ER-005. The test results support the scaling correlation derived previously in the Title I program. The tests also concluded that a partially filled tank requires less mixing power, and horizontal and angled jets in combination (H/A mixer) are significantly more effective than the two horizontal jet mixers (H/H mixer) when used for mixing slurry with a high solids concentrations.

The DACS, which is housed in a trailer located just outside of the north fence at the SY tank farm, receives input signals from a variety of sensors located in and around the SY-101 tank. These sensors provide information such as: tank vapor space and ventilation system H{sub 2} concentration; tank waste temperature; tank pressure; waste density; operating pump parameters such as speed, flow, rotational position, discharge pressure, and internal temperature; strain (for major equipment); and waste level. The output of these sensors is conditioned and transmitted to the DACS computers where these signals are displayed, recorded, and monitored for out-of-specification conditions. If abnormal conditions are detected, then, in certain situations, the DACS automatically generates alarms and causes the system to abort pump operations. The portions of the system to be tested include: new RGA5 gas monitor; existing gas chromatographs; FTIR; B and K (Photo) NH{sub 3} equipment; any new or changed Genesis screens; and I/O Drop 13.

This report documents water column measurements made during the 1994 Loch Linnhe experiment, a joint US/UK radar ocean imaging experiment. Part 1 summarizes the profiles of temperature, salinity, density, Brunt-Vaisala frequency, and horizontal currents resolved into along and cross track directions. Internal wave dispersion relations, phase and group velocities, and eigenfunctions for modes 1 and 2 are computed for each profile. The effect of depth on these derived internal wave parameters is examined as well by computing eigenvalues and eigenfunctions for two different depths. The trials were conducted in Loch Linnhe, Scotland during the period from September 4, 1994 to September 17, 1994. The measurements reported herein were made from on board the R. V. Calanus, a research vessel operated by the Dunstaffnage Marine Laboratory (DML). The Calanus was moored approximately 125 meters from the track of the wake generating ship, either the R. V. Colonel Templer or a {open_quotes}Dog{close_quotes} class tug, the Collie. The depth at the mooring location was approximately 45 meters, while the depth at the closest point along the ship track was approximately 80 meters. For further details of the experiment, one is referred to the Loch Linnhe Experiment 1994: Trial Plan, Draft Version 3.0.

A novel flue gas desulfurization technology has been developed at the University of Cincinnati incorporating a circulating fluidized bed absorber (CFBA) reactor with dry sorbent. The main features of CFBA are high sorbent/gas mixing ratios, excellent heat and mass transfer characteristics, and the ability to recycle partially utilized sorbent. Subsequently, higher SO{sub 2} removal efficiencies with higher overall sorbent utilization can be realized compared with other dry sorbent injection scrubber systems.

This procedure will test the 17B MIT sensor inputs to the DACS trailer after installation of new thermocouple multiplexers and associated computer software.

The Multistation Offgas Analysis System (MOAS) is a fully automated instrument which can independently measure the gases emitted by up to four samples in containers heated in ovens. A mass spectrometer is used to determine accurately their flow rates. There are six interconnected high vacuum pumping stations, one for each of the sample containers, one for the mass spectrometer, and one for the calibrated leaks which are used to calibrate the mass spectrometer. Quadstar 421{trademark} is the software package marketed by Balzers, the manufacturer of the mass spectrometer. This software used by MOAS is a combination of Quadstar 421{trademark}, special routines, called sequences in the Balzers nomenclature, and compiled programs that controls MOAS. Tests are run repeatedly on each of the four oven stations, while stations that are not ready, or do not have a sample are skipped. While the computer is sitting idle between tests, the software monitors the vacuum system. If necessary, the software will shut down a pumping station that is not operating correctly. The status of pumping stations and tests, filenames for data and oven temperatures are stored on disk, so the software can recover from a power failure. The operator can use the software to …

This report describes a method for calculating mixed heat transfer through the multilayer insulation used to insulate a 4 K liquid helium cryostat. The method described here permits one to estimate the insulation potential for a multilayer insulation system from first principles. The heat transfer regimes included are: radiation, conduction by free molecule gas conduction, and conduction through continuum gas conduction. Heat transfer in the transition region between the two gas conduction regimes is also included.

This revision responds to RL comments and increases the discussion of the ``effective hazard categorization`` and the readiness review basis. The safety assessment is made for the activities for the preparation and installation of the discharge chute isolation barriers. The safety assessment includes a hazard assessment and comparison of potential accidents/events to those addressed by the current safety basis documentation. No significant hazards were identified. An evaluation against the USQ evaluation questions were made and the determination made that the activities do not represent a USQ. Hazard categorization techniques were used to provide a basis for readiness review classification.
