Development of Low Cost Total Energy Exchange Devices for Reducing Building Energy Consumption (open access)

Development of Low Cost Total Energy Exchange Devices for Reducing Building Energy Consumption

The primary goal of this program is to develop a commercially viable enthalpy exchangers that exhibits performance comparable to state-of-the-art exchangers, meets flammability test standards, supports no biological growth, maintains mechanical integrity for a 10 year life (typical of competitive warrantees) and exhibits a total media raw material cost of approximately 1/5 of that of the competition. The first three program tasks were devoted to: (1) gathering background information on competitors and their methods of manufacturing; (2) establishing experimental and evaluation procedures for the program; (3) identifying potential desiccants, supports and binders to be tested; (4) preparing matrix combinations on a laboratory scale; (5) testing component combinations for equilibrium moisture uptakes at different relative humidities (isotherms) and dynamic moisture adsorption rates; (6) using media adsorption properties to models to predict exchanger performance; (7) estimating ease of manufacture and finished wheel costs; and (8) calculating raw material, wheel and cassette costs based on the best media formulations. Since the rotary enthalpy exchangers have high rotational speeds, uptake rate is at least as important as equilibrium moisture uptake. Therefore, a procedure and apparatus were developed to determine adsorption rate so that the Lewis number (the ratio of mass transfer resistance to heat …

From Loops to Trees By-passing Feynman's Theorem (open access)

From Loops to Trees By-passing Feynman's Theorem

We derive a duality relation between one-loop integrals and phase-space integrals emerging from them through single cuts. The duality relation is realized by a modification of the customary + i0 prescription of the Feynman propagators. The new prescription regularizing the propagators, which we write in a Lorentz covariant form, compensates for the absence of multiple cut contributions that appear in the Feynman Tree Theorem. The duality relation can be applied to generic one-loop quantities in any relativistic, local and unitary field theories. It is suitable for applications to the analytical calculation of one-loop scattering amplitudes, and to the numerical evaluation of cross-sections at next-to-leading order.

High efficiency shale oil recovery (open access)

High efficiency shale oil recovery

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical conditions (heating, mixing, pyrolysis, oxidation) exist in both systems.The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed this quarter. (1) Twelve pyrolysis runs were made on five different oil shales. …

The single electron chemistry of coals. [Quarterly] report, January 1, 1991--March 31, 1991

The simplest explanation for these shifts in the infrared spectra is there exists in coal single electron donors which are capable of transferring an electron to TCNQ in the ground state. All of the TCNQ placed in the coal appears to be converted to the radical anion as displayed in the IR spectrum for all of the coals except for the 100% loading.

Primary production off Southern California relative to surface layer carbon budgets: A component of the California Basins Study, CaBS. Final report, [1 June 1989--14 November 1991] (open access)

Primary production off Southern California relative to surface layer carbon budgets: A component of the California Basins Study, CaBS. Final report, [1 June 1989--14 November 1991]

This study started on 1 June 1989 and ended 14 November 1991. Two moored in situ natural fluorometers were deployed in January 1990 to collect bio-optical data for one year, making ground truth measurements around the mooring during 4 cruises. This one-year time series would investigate how the short-term physical forcing aliases the long-term primary production record such that the apparent, larger interannual variability in the record is in reality ``noise`` due to short-term fluctuations in the rate of nutrient input to the euphotic zone. These continuous measurements from moored bio-optical instruments would also allow better estimates of the mean and variance in primary production in these waters than has previously been available from shipboard measurements, as well as, phytoplankton response to short-term physical events. Ancillary measurements that were made were: (1) characterization of the apparent and inherent optical properties, (2) photosynthetic pigment distributions using both HPLC and standard fluorometric methods, (3) carbon, hydrogen and nitrogen content of suspended particulate matter, (4) primary production using conventional {sup 14}C methods from simulated in situ experiments.

Nuclear criticality safety bounding analysis for the in-tank-precipitation (ITP) process, impacted by fissile isotopic weight fractions (open access)

Nuclear criticality safety bounding analysis for the in-tank-precipitation (ITP) process, impacted by fissile isotopic weight fractions

The In-Tank Precipitation process (ITP) receives High Level Waste (HLW) supernatant liquid containing radionuclides in waste processing tank 48H. Sodium tetraphenylborate, NaTPB, and monosodium titanate (MST), NaTi{sub 2}O{sub 5}H, are added for removal of radioactive Cs and Sr, respectively. In addition to removal of radio-strontium, MST will also remove plutonium and uranium. The majority of the feed solutions to ITP will come from the dissolution of supernate that had been concentrated by evaporation to a crystallized salt form, commonly referred to as saltcake. The concern for criticality safety arises from the adsorption of U and Pt onto MST. If sufficient mass and optimum conditions are achieved then criticality is credible. The concentration of u and Pt from solution into the smaller volume of precipitate represents a concern for criticality. This report supplements WSRC-TR-93-171, Nuclear Criticality Safety Bounding Analysis For The In-Tank-Precipitation (ITP) Process. Criticality safety in ITP can be analyzed by two bounding conditions: (1) the minimum safe ratio of MST to fissionable material and (2) the maximum fissionable material adsorption capacity of the MST. Calculations have provided the first bounding condition and experimental analysis has established the second. This report combines these conditions with canyon facility data to evaluate …

Interactive Computer-Enhanced Remote Viewing System (ICERVS): Subsystem design report - Phase 2 (open access)

Interactive Computer-Enhanced Remote Viewing System (ICERVS): Subsystem design report - Phase 2

This ICERVS Phase II Subsystem Design Report describes the detailed software design of the Phase II Interactive Computer-Enhanced Remote Viewing System (ICERVS). ICERVS is a computer-based system that provides data acquisition, data visualization, data analysis, and model synthesis to support robotic remediation of hazardous environments. Due to the risks associated with hazardous environments, remediation must be conducted remotely using robotic systems, which, in turn, must rely on 3D models of their workspace to support both task and path planning with collision avoidance. Tools such as ICERVS are vital to accomplish remediation tasks in a safe, efficient manner. The 3D models used by robotic systems are based on solid modeling methods, in which objects are represented by enclosing surfaces (polygons, quadric surfaces, patches, etc.) or collections of primitive solids (cubes, cylinders, etc.). In general, these 3D models must be created and/or verified by actual measurements made in the robotics workspace. However, measurement data is empirical in nature, with typical output being a collection of xyz triplets that represent sample points on some surface(s) in the workspace. As such, empirical data cannot be readily analyzed in terms of geometric representations used in robotic workspace models. The primary objective of ICERVS is to …

High SO{sub 2} removal efficiency testing. Technical progress report, [January 1--March 31, 1993]

This document provides a discussion of the technical progress on DOE-PETC Project Number AC22-92PC91338, ``High Efficiency SO{sub 2} Removal Testing,`` for the time period from January 1 through March 31, 1993. The project involves testing at full-scale utility flue gas desulfurization (FGD) systems to evaluate low capital cost upgrades that may allow these systems to achieve up to 98% SO{sub 2} removal efficiency. The options to be evaluated primarily involve the addition of organic acid buffers to the FGD systems. The ``base`` project involves testing at one site, Tampa Electric Company`s Big Bend Station. Up to five optional sites may be added to the program at the discretion of DOE-PETC. By March 31, 1993, four of those five options had been exercised. The options include testing at Hoosier Energy`s Merom Station (Option I), Southwestern Electric Power Company`s (SWEPCo) Pirkey Station (Option II), PSI Energy`s Gibson Station (Option III), and Duquesne Light`s Elrama Station (Option IV). The remainder of this document is divided into three sections. Section 2, Project Summary, provides a brief overview of the technical efforts on this project during the quarter.

FORTE log periodic antenna. Phase 1, Final report (open access)

FORTE log periodic antenna. Phase 1, Final report

This report summarizes the results of ABLE`s design study of the FORTE deployable log periodic antenna. The resulting Baseline Design of the antenna is the basis for ABLE`s proposal for Phase II of this program. ABLE`s approach to meeting the requirements is to use a coilable ABLE mast as the deployable structure ``backbone`` of the antenna and to use deployable tubes for. the log periodic dipole elements of the antenna. This general approach was adopted at the outset of the Phase I Design Study. The remainder of the study was devoted to detailed design and analysis to properly size these types of mast and antenna elements and to design their deployment mechanisms. Demonstration models of the mast and antenna element deployer were fabricated as part of Phase I study. The study showed that ABLE`s design approach is feasible and can meet all the specified design requirements except the mass limit of 13.5 kg. Results of the design and analysis studies are summarized in this report. The mast and dipole element deployer are to be demonstrated to LANL personnel at the conclusion of this Phase I study.

Geological and petrophysical characterization of the Ferron Sandstone for 3-D simulation of a fluvial-deltaic reservoir. [Quarterly] report, January 1--March 31, 1994 (open access)

Geological and petrophysical characterization of the Ferron Sandstone for 3-D simulation of a fluvial-deltaic reservoir. [Quarterly] report, January 1--March 31, 1994

The objective of this project is to develop a comprehensive, interdisciplinary, quantitative characterization of a fluvial-deltaic reservoir which will allow realistic interwell and reservoir-scale modeling to be used for improved oil-field development in similar reservoirs world wide. The geological and petrophysical properties of the Cretaceous Ferron Sandstone in east-central Utah will be quantitatively determined. Both new and existing data will be integrated into a 3-D representation of spatial variations in porosity, storativity, and tensorial rock permeability at a scale appropriate for interwell to regional-scale reservoir simulation. Results could improve reservoir management through proper infill and extension drilling strategies, reduce economic risks, increase recovery from existing oil fields, and provide more reliable reserve calculations. Transfer of the project results to the petroleum industry will be an integral component of the project. The technical progress is divided into several sections corresponding to subtasks outlined in the Regional Stratigraphy Task and the Case Studies Task of the original proposal. The primary objective of the Regional Stratigraphy Task is to provide a more detailed interpretation of the stratigraphy of the Ferron Sandstone outcrop belt from Last Chance Creek to Ferron Creek. The morphological framework established from the case studies will be used to generate …

Enhanced oil recovery utilizing high-angle wells in the Frontier Formation, Badger Basin Field, Park County, Wyoming. Quarterly technical progress report, 1 January 1994--31 March 1994

Sierra Energy Company, in consultation with Rim Companies, concluded that additional work was required for Subtask 2.1.4 -- Interpret data, of Task 2.1 - Acquire 3-D seismic data. The goal of this subtask was to interpret the 3-D seismic data, using a workstation, in order to locate the surface and subsurface positions for the slant and horizontal wellbores. Although this goal had been reached, more work was needed for plotting maps and seismic sections. Furthermore, it was determined that an additional look at the amplitude distribution in the Frontier sands would greatly benefit the interpretation.

Radioactive demonstration of DWPF product control strategy (open access)

Radioactive demonstration of DWPF product control strategy

The effectiveness of the product and process control strategies that will be utilized by the Defense Waste Processing Facility (DWPF) was demonstrated during a campaign in the Shielded Cells Facility (SCF) of the Savannah River Technology Center (SRTC). The remotely operated process included the preparation of the melter feed, vitrification in a slurry-fed 1/100th scale melter and analysis of the glass product both for its composition and durability. The campaign processed approximately 10 kg (on a dry basis) of radioactive sludge from Tank 51. This sludge is representative of the first batch of sludge that will be sent to the DWPF for immobilization into borosilicate glass. Additions to the sludge were made based on calculations using the Product Composition Control System (PCCS). Analysis of the glass produced during the campaign showed that a durable glass was produced with a composition similar to that predicted using the PCCS.
