FTR.DOC PREFACE In the course of study and in the interim between the draft technical report and this final technical report, PacifiCorp made a few changes to the proposed Klamath Hydroelectric Project (Project). The newly proposed Project begins at the J.C. Boyle Development and continues downstream to the Iron Gate Development. The Spring Creek diversion is now included in the Fall Creek Development. The East Side, West Side, and Keno developments are no longer part of the Project. Keno dam will remain in operation, but is not included in the Federal Energy Regulatory Commission (FERC) Project because the development does not have generation facilities, and its operation does not substantially benefit generation at PacifiCorp's downstream hydroelectric developments. © February 2004 PacifiCorp Land Use, Visual, and Aesthetic Resources FTR.DOC Land Use, Visual, and Aesthetic Resources FTR Page v LIST OF ABBREVIATIONS AND ACRONYMS ACEC Area of Critical Environmental Concern ac-ft acre-feet ACHP Advisory Council on Historic Preservation ACS Aquatic Conservation Strategy AD accretion/depletion ADA Americans with Disabilities Act ADAAG Americans with Disabilities Act Accessibility Guidelines ADCP Acoustic Doppler Current Profiler AINW Archaeological Investigations Northwest AMS accelerator mass spectrometry ANOVA analysis of variants APE area of potential effect ARPA Archaeological Resources

    Article Comparison of Tab-To-Busbar Ultrasonic Joints for Electric Vehicle Li-Ion Battery Applications Abhishek Das * , Anup Barai, Iain Masters and David Williams WMG, The University of Warwick, Coventry CV4 7AL, UK; [email protected] (A.B.); [email protected] (I.M.); [email protected] (D.W.) * Correspondence: [email protected]; Tel.: +44-247-657-3742 Received: 26 June 2019; Accepted: 12 September 2019; Published: 14 September 2019 Abstract: Recent uptake in the use of lithium-ion battery packs within electric vehicles has drawn significant attention to the selection of busbar material and corresponding thickness, which are usually based on mechanical, electrical and thermal characteristics of the welded joints, material availability and cost. To determine joint behaviour corresponding to critical-to-quality criteria, this study uses one of the widely used joining technologies, ultrasonic metal welding (UMW), to produce tab-to-busbar joints using copper and aluminium busbars of varying thicknesses. Joints for electrical and thermal characterisation were selected based on the satisfactory mechanical strength determined from the T-peel tests. Electrical contact resistance and corresponding temperature rise at the joints were compared for different tab-to-busbar joints by passing current through the joints. The average resistance or temperature increase from the 0.3 mm Al tab was 0.6 times higher than the 0.3 mm Cu[Ni] tab, irrespective of busbar selection. Keywords: electric vehicle; thin metal film; ultrasonic metal welding; electrical resistance; temperature rise 1. Introduction Lithium-ion (Li-ion) electrochemistry-based secondary batteries are now widely used for electrification of automotive vehicles due to several advantages, including high energy density, low self-discharge and portability [1,2].

  • The Case for Dam Removal on the Klamath S
    Building The Case for Dam Removal on the Klamath S. Craig Tucker, Ph.D. Klamath Campaign Coordinator Karuk Tribe 12/12/03 Pacificorp, a subsidiary of the large multinational power corporation Scottish Power, is in the process of relicensing its Klamath River dams. Since hydropower dams are relicensed only once every 30-50 years, relicensing represents a once in a lifetime opportunity to change flow regimes or decommission dams. The Karuk Tribe believes that the removal of dams on the Klamath should be fully evaluated as dam removal appears to be key in the restoration of native fishes to the upper basin. Our position is supported by sound science and policy research. These dams contribute little to the energy supply1 The California Energy Commission (CEC) reviewed the energy affects of full or partial decommissioning. Their conclusions were that: “Because of the small capacity of the Klamath hydro units…removal of these units will not have a significant reliability impact on a larger regional scale.” The report went on to state: “…decommissioning is a feasible alternative from the perspective of impacts to statewide electricity resource adequacy and that replacement energy is available in the near term.” The National Academy of Science recommends a full evaluation of dam removal2 A recent report by the most prestigious scientific minds in America, the National Academy of Science, recommends that: “serious evaluation should be made of the benefits to coho salmon from the elimination of Dwinell Dam [on the Shasta River] and Iron Gate Dam on the grounds that these dams block substantial amounts of coho habitat…” The California State Water Resources Control Board calls for dam removal studies3 The California State Water Resources Control Board is one party involved in the relicensing of the Klamath Project.

  • A System Level Approach to the Design and Analysis of PCB
    ABSTRACT ABERG, BRYCE. An Approach for the Design and Analysis of PCB Busbars in High Power SiC Inverters using FEA Tools. (Under the direction of Iqbal Husain). Wide band gap semiconductors, including silicon carbide (SiC) and gallium nitride (GaN), allow engineers to develop higher power density systems compared to traditional Si technology. Silicon Carbide, in particular, has promising applications to the automotive, aerospace, and utilities industries among others. Commonly used to create solid electrical and mechanical connections in high power systems, busbars are critical in ensuring system reliability in terms of voltage spike and temperature rise. Laminated busbars, commonly consisting of heavy copper planes separated by a non-conductive substrate, are widely used in industry due to their mechanical, electrical, and thermal robustness. Printed circuit boards (PCB) have advantages over laminated busbars in developing high power density systems. While the optimization of laminated busbar design has been widely reported, high power PCB busbars are less represented in literature. Therefore, a simulation-based methodology used to analyze and optimize the design of PCB busbars using finite element analysis (FEA) tools will be discussed. Two systems were considered for these studies including a 135 kW SiC traction inverter and a 125 kVA SiC inverter used in an active harmonic filter. Components comprising the power loop, including the PCB busbar, power module, and heavy duty interconects were modeled in Q3D to extract the loop inductance for both systems. The two experimental methods used to validate simulation results included double pulse tests (DPT) and impedance measurements. The busbar design in the 135 kW system was optimized using Ansys Q3D, resulting in a 19 % reduction in voltage spike amplitude according to double pulse tests.

  • Producing Fuel and Electricity from Coal with Low Carbon Dioxide Emissions
    Producing Fuel and Electricity from Coal with Low Carbon Dioxide Emissions K. Blok, C.A. Hendriks, W.C. Turkenburg Depanrnent of Science,Technology and Society University of Utrecht Oudegracht320, NL-351 1 PL Utrecht, The Netherlands R.H. Williams Center for Energy and Environmental Studies Princeton University Princeton, New Jersey08544, USA June 1991 Abstract. New energy technologies are needed to limit CO2 emissions and the detrimental effects of global warming. In this article we describe a process which produces a low-carbon gaseousfuel from coal. Synthesis gas from a coal gasifier is shifted to a gas mixture consisting mainly of H2 and CO2. The CO2 is isolated by a physical absorption process, compressed,and transported by pipeline to a depleted natural gas field where it is injected. What remains is a gaseousfuel consisting mainly of hydrogen. We describe two applications of this fuel. The first involves a combined cycle power plant integrated with the coal gasifier, the shift reactor and the CO2 recovery units. CO2 recovery and storage will increase the electricity production cost by one third. The secondprovides hydrogen or a hydrogen-rich fuel gas for distributed applications, including transportation; it is shown that the fuel can be produced at a cost comparable to projected costs for gasoline. A preliminary analysis reveals that all components of the process described here are in such a phase of development that the proposed technology is ready for demonstration. ~'> --. ~'"' .,.,""~ 0\ ~ 0\0 ;.., ::::. ~ ~ -.., 01) §~ .5~ c0 ~.., ~'> '" .~ ~ ..::. ~ ~ "'~'" '" 0\00--. ~~ ""00 Q....~~ '- ~~ --. ~.., ~ ~ ""~ 0000 .00 t¥") $ ~ .9 ~~~ .- ..~ c ~ ~ ~ .~ O"Oe) """1;3 .0 .-> ...~ 0 ~ ,9 u u "0 ...~ --.
