Environmental Disclosure: Briefing on GAO's Findings and Recommendations

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "The Securities and Exchange Commission's (SEC) primary mission is to protect investors and the integrity of securities markets. Among other things, SEC regulations require companies to file reports with SEC disclosing information that would be considered "material" to a reasonable investor. A matter is material if there is a substantial likelihood that a reasonable person would consider it important. Env… more

Heat Pump Water Heater Technology: Experiences of Residential Consumers and Utilities

Description: This paper presents a case study of the residential heat pump water heater (HPWH) market. Its principal purpose is to evaluate the extent to which the HPWH will penetrate the residential market sector, given current market trends, producer and consumer attributes, and technical parameters. The report's secondary purpose is to gather background information leading to a generic framework for conducting market analyses of technologies. This framework can be used to compare readiness and to factor … more

Sediment studies of the biological factors controlling the reduction of U(VI).

Description: Studies were conducted primarily with sediments, both in laboratory incubations and in a field experiment, with supporting studies with pure cultures. To our knowledge the sediment studies were the first on microbial U(VI) reduction in actual uranium-contaminated subsurface sediments, under conditions that mimic those found in situ. Important findings included: (1) U(VI) reduction is a biotic process in subsurface sediments. (2) U(VI) reduction can be stimulated most effectively with the additi… more

Supplement Analysis for the Watershed Management Program EIS - Idaho Model Watershed Habitat Projects - Welp Riparian Enhancement Fence

Description: The Bonneville Power Administration is proposing to fund the installation of approximately 1.5 miles of post and wire fence along Valley Creek in Stanley, Idaho. The proposed fence will meet or exceed BPA's minimum requirement of a 35-foot setback from the stream. Fence posts will be driven into the ground with a post ponder. The goal of this project is to enhance salmon and steelhead rearing and migration habitat through exclusion fencing.

Simulating Electron Cloud Effects in Heavy-Ion Beams

Description: Stray electrons can be introduced in heavy ion fusion accelerators as a result of ionization of ambient gas or gas released from walls due to halo-ion impact, or as a result of secondary-electron emission. We summarize here results from several studies of electron-cloud accumulation and effects: (1) Calculation of the electron cloud produced by electron desorption from computed beam ion loss; the importance of ion scattering is shown; (2) Simulation of the effect of specified electron cloud dis… more

Exploration of ion-antiproton instabilities in the Recycler Ring

Description: Instabilities driven by ions (or electrons) trapped within the space charge potential of a circulating beam are common in accelerators and storage rings. In the recycler, the stored antiproton ({bar p}) beam could trap positive ions (H{sub 2}{sup +}, CO{sup +}, etc.). Conditions for trapping are discussed, and trapping potentials are calculated. Ion trapping can be reduced by clearing electrodes, a beam-free gap (or gaps), and beam shaking. Tune shifts, coherent instabilities and other effects … more

Engineering Spectral Control Using Front Surface Filters for Maximum TPV Energy Conversion System Performance

Description: Energy conversion efficiencies of better than 23% have been demonstrated for small scale tests of a few thermophotovoltaic (TPV) cells using front surface, tandem filters [1,2]. The engineering challenge is to build this level of efficiency into arrays of cells that provide useful levels of energy. Variations in cell and filter performance will degrade TPV array performance. Repeated fabrication runs of several filters each provide an initial quantification of the fabrication variation for fron… more

Auger and Radiative Recombination Coefficients in 0.55 eV InGaAsSb

Description: A radio-frequency (RF) photoreflectance technique, which senses changes in sample conductivity as carriers recombine following excitation by a laser pulse, has been used to measure the recombination parameters in 0.55 eV InGaAsSb lattice matched to GaSb. Doubly-capped lifetime structures with variable active layer thicknesses are used to extract the surface recombination velocity (SRV), while analysis of the samples with different doping concentrations is used to obtain Auger (C) and radiative … more

Isotropic proton-detected local-field nuclear magnetic resonancein solids

Description: A new nuclear magnetic resonance (NMR) method is presented which produces linear, isotropic proton-detected local-field spectra for InS spin systems in powdered samples. The method, HETeronuclear Isotropic Evolution (HETIE), refocuses the anisotropic portion of the heteronuclear dipolar coupling frequencies by evolving the system under a series of specially designed Hamiltonians and evolution pathways. The theory behind HETIE is represented along with experimental studies conducted on a powdere… more

Demonstration of an Instrument for On-Line Measuring of the Alpha Radiation

Description: The Salt Waste Processing Facility and the Actinide Removal Process at the Savannah River Site will remove alpha emitting radioisotopes from High Level Waste to meet regulatory disposal requirements. The removal occurs prior to removal of the radioactive cesium. Both facility designs currently include verification measurement using conventional wet chemistry approaches remote from the operation. Use of an on-line monitor for this purpose offers the opportunity to shorten process cycle time and … more

Comparison of Two Different Wavelength Tuning Schemes in a Seeded High-Gain FEL

Description: In the following text we analyze and compare results of the two publications ([1], [2]), dedicated to development of the tunable high-gain Free Electron laser (FEL), seeded by an external source. As a conclusion we summarize similarities and differences between these concepts. This note is initiated by the polemics on the similarity of two different schemes of the wavelength tuning in a seeded high-gain FEL. Below we will be calling the scheme, presented by S. Biedron, S, Milton and H. Freund i… more

911 Call Center Legislation: S. 1250 and H.R. 2898

Description: This article discusses the 2003 Congress bipartisan E911 (Enhanced 911) legislation introduced in both chambers. Moreover, the article describes the difference in parallel provisions each bill contains that have significant implications for emergency communication policy. The article defines Enhanced 911 as the capability of identifying the phone number and location of a call to a PSAP (Public Safety Answering Points). This report characterizes the cost to PSAPs of upgrading systems and support… more

Stability and Design Criteria for CICC with a Broad Transition to Normal State

Description: Stability in cable-in-conduit conductors (CICC) against perturbations is often associated with transient heat removal of heat generated in the normal zone. Based on this approach, stability criterion requires low current density in the strands. This criterion is often used for design of the magnets for fusion devices like ITER, KSTAR and others. We show that this criterion is not a mandatory requirement for serviceability of CICC and that CICC may work reliably at higher current densities. In c… more

Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystems Services Quarterly Report

Description: The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. We are currently estimating the acreage of lands in VA, WV, KY, OH, and PA mined under SMCRA and reclaimed to non-forested post-mining land uses that are not currently under active management, and therefore can be considered as availab… more
