100kW Energy Transfer Multiplexer Power Converter Prototype Development Project (open access)

100kW Energy Transfer Multiplexer Power Converter Prototype Development Project

Project Final Report for "100kW Energy Transfer Multiplexer Power Converter Prototype Development Project" prepared under DOE grant number DE-FG36-03GO13138. This project relates to the further development and prototype construction/evaluation for the Energy Transfer Multiplexer (ETM) power converter topology concept. The ETM uses a series resonant link to transfer energy from any phase of a multiphase input to any phase of a multiphase output, converting any input voltage and frequency to any output voltage and frequency. The basic form of the ETM converter consists of an eight (8)-switch matrix (six phase power switches and two ground power switches) and a series L-C resonant circuit. Electronic control of the switches allows energy to be transferred in the proper amount from any phase to any other phase. Depending upon the final circuit application, the switches may be either SCRs or IGBTs. The inherent characteristics of the ETM converter include the following: Power processing in either direction (bidirectional); Large voltage gain without the need of low frequency magnetics; High efficiency independent of output load and frequency; Wide bandwidth with fast transient response and; Operation as a current source. The ETM is able to synthesize true sinusoidal waveforms with low harmonic distortions. For a low …

2005 Annual Health Physics Report for HEU Transparency Program (open access)

2005 Annual Health Physics Report for HEU Transparency Program

During the 2005 calendar year, LLNL provided health physics support for the Highly Enriched Uranium Transparency Program (HEU-TP) in external and internal radiation protection and technical expertise into matters related to BDMS radioactive sources and Russian radiation safety regulatory compliance. For the calendar year 2005, there were 161 person-trips that required dose monitoring of the U.S. monitors. Of the 161 person-trips, 149 person-trips were SMVs and 12 person-trips were Transparency Monitoring Office (TMO) trips. Additionally, there were 11 monitoring visits by TMO monitors to facilities other than UEIE and 3 to UEIE itself. There were two monitoring visits (source changes) that were back to back with 16 monitors. Each of these concurring visits were treated as single person-trips for dosimetry purposes. Counted individually, there were 191 individual person-visits in 2005. The LLNL Safety Laboratories Division provided the dosimetry services for the HEU-TP monitors.

Afghanistan: Post-War Governance, Security, and U.S. Policy

The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and Al Qaeda fighters and leaders that remain at large, including Osama bin Laden. As the war against remaining Al Qaeda and Taliban elements winds down, the United States is shifting its military focus toward stabilizing the interim government, including training a new Afghan national army, and supporting the international security force (ISAF) that is helping the new government provide security.

Alteration of U(6)-Phases Under Oxidizing Conditions (open access)

Alteration of U(6)-Phases Under Oxidizing Conditions

Uranium-(VI) phases are the primary alteration products of the UO{sub 2} in spent nuclear fuel and the UO{sub 2+x}, in natural uranium deposits. The U(VI)-phases generally form sheet structures of edge-sharing UO{sub 2}{sup 2+} polyhedra. The complexity of these structures offers numerous possibilities for coupled-substitutions of trace metals and radionuclides. The incorporation of radionuclides into U(VI)-structures provides a potential barrier to their release and transport in a geologic repository that experiences oxidizing conditions. In this study, we have used natural samples of UO{sub 2+x}, to study the U(VI)-phases that form during alteration and to determine the fate of the associated trace elements.

The Americans with Disabilities Act and Emergency Preparedness and Response (open access)

The Americans with Disabilities Act and Emergency Preparedness and Response

The Americans with Disabilities Act provides broad nondiscrimination protection for individuals with disabilities in employment, public services, and public accommodation and services operated by private entities. Although the ADA does not include provisions specifically discussing its application to disasters such as Hurricane Katrina, its nondiscrimination provisions are applicable to emergency preparedness and responses to disasters. For example, this would mean that emergency planning should include individuals with disabilities and that emergency shelters should be accessible to individuals with disabilities. In order to further the goals of the ADA, President Bush issues an Executive Order on Jluy 22nd, 2004relating to emergency preparedness for individuals with disabilities and establishing the Interagency Coordinating Council on Emergency Preparedness and Individuals with Disabilities. The Department of Homeland Security issued a Nationwide Plan Review Phase 2 Report, which includes a discussion of people with disabilities and emergency planning and readiness. The National Council on Disability has also issued a recommendation on emergency preparation and disaster relief relating to individuals with disabilities. Legislation has also been introduced to address the needs of individuals with disabilities in emergency planning and relief.

Area Monitoring Dosimeter Program for the Pacific Northwest National Laboratory: Results for CY 2005

Pacific Northwest National Laboratory (PNNL) established an area monitoring dosimeter program in accordance with Article 514 of the Department of Energy (DOE) Radiological Control Manual (RCM) in January 1993. This program is to minimize the number of areas requiring issuance of personnel dosimeters and to demonstrate that doses outside Radiological Buffer Areas are negligible. In accordance with 10 CFR Part 835.402 (a)(1)-(4) and Article 511.1 of the PNNL Radiological Control Program Description, personnel dosimetry shall be provided to (1) radiological workers who are likely to receive at least 100 mrem annually, and (2) declared pregnant workers, minors, and members of the public who are likely to receive at least 50 mrem annually. Program results for calendar years 1993-2005 confirm that personnel dosimetry is not needed for individuals located in areas monitored by the program

An Automated Magnet Positioning System For Use in the Next Linear Collider (open access)

An Automated Magnet Positioning System For Use in the Next Linear Collider

The Next Linear Collider (NLC) is conceived as the world’s most powerful electron-positron particle accelerator. Throughout the NLC, the beam itself will be used to measure errors in the positions of the lattice elements. This beam-based alignment strategy is an essential element of the NLC’s design and precision adjustment systems have been identified as a critical enabling technology. Square One proposes a new type of precision manipulator that could be adapted for applications throughout the accelerator. As envisioned, this “Tri-Sphere” Adjustment System will possess up to six, non-redundant degrees of freedom, be capable of sub-micron resolutions and have ultimate load capacities in excess of 10,000 kg. The system will accommodate thermal expansions and contractions of the objects being supported and can be either motorized or manually actuated. Phase I development tasks will include detailed manipulator design, solution of the associated kinematic equations of motion and evaluation of actuators, gear reducers and transmission systems. The Phase I effort will culminate in the fabrication and full evaluation of a system prototype. A successfully developed Tri-Sphere manipulator could also be used to actively position critical fusion optics, adjust communication dishes or perform parts handling tasks in harsh manufacturing environments.

Bioagent Sample Matching using Elemental Composition Data: an Approach to Validation (open access)

Bioagent Sample Matching using Elemental Composition Data: an Approach to Validation

Sample matching is a fundamental capability that can have high probative value in a forensic context if proper validation studies are performed. In this report we discuss the potential utility of using the elemental composition of two bioagent samples to decide if they were produced in the same batch, or by the same process. Using guidance from the recent NRC study of bullet lead analysis and other sources, we develop a basic likelihood ratio framework for evaluating the evidentiary weight of elemental analysis data for sample matching. We define an objective metric for comparing two samples, and propose a method for constructing an unbiased population of test samples. We illustrate the basic methodology with some existing data on dry Bacillus thuringiensis preparations, and outline a comprehensive plan for experimental validation of this approach.

Black Hole Attractors and Pure Spinors (open access)

Black Hole Attractors and Pure Spinors

We construct black hole attractor solutions for a wide class of N = 2 compactifications. The analysis is carried out in ten dimensions and makes crucial use of pure spinor techniques. This formalism can accommodate non-Kaehler manifolds as well as compactifications with flux, in addition to the usual Calabi-Yau case. At the attractor point, the charges fix the moduli according to {Sigma}f{sub k} = Im(C{Phi}), where {Phi} is a pure spinor of odd (even) chirality in IIB (A). For IIB on a Calabi-Yau, {Phi} = {Omega} and the equation reduces to the usual one. Methods in generalized complex geometry can be used to study solutions to the attractor equation.

Border Security: Barriers Along the U.S. International Border

Congress has been considering expanding the barriers currently deployed along the U.S. international land border. Currently, the United States Border Patrol (USBP) deploys fencing, which aims to impede the illegal entry of individuals, and vehicle barriers, which aim to impede the illegal entry of vehicles (but not individuals) along the border. A number of policy issues concerning border barriers generally and fencing specifically may be of interest to Congress, including, but not limited to: their effectiveness; their costs versus their benefits; their location; their design; and their potential diplomatic ramifications. Prominent bills include House-passed H.R. 4437 and H.R. 6061, and Senate-passed S. 2611, and H.R. 5631.

"Bunker Busters": Robust Nuclear Earth Penetrator Issues, FY2005-FY2007

The Robust Nuclear Earth Penetrator (RNEP) program has been the most controversial nuclear weapon program in Congress for the last several years. Supporters argue that it is needed to attack hard and deeply buried targets (such as leadership bunkers) in countries of concern, thereby deterring or defeating challenges from such nations; critics assert that RNEP would lower the threshold for use of nuclear weapons and prompt other nations to develop nuclear weapons to deter U.S. attack. This report presents a brief technical background on RNEP, then discusses the history of RNEP in Congress and the Administration for the FY2005 and FY2006 budget cycles.
