Electrical Core Transformer for Grid Improvement Incorporating Wire Magnetic Components

The research reported herein adds to the understanding of oil-immersed distribution transformers by exploring and demonstrating potential improvements in efficiency and cost utilizing the unique Buswell approach wherein the unit is redesigned, replacing magnetic sheet with wire allowing for improvements in configuration and increased simplicity in the build process. Exploration of new designs is a critical component in our drive to assure reduction of energy waste, adequate delivery to the citizenry, and the robustness of U.S. manufacturing. By moving that conversation forward, this exploration adds greatly to our base of knowledge and clearly outlines an important avenue for further exploration. This final report shows several advantages of this new transformer type (outlined in a report signed by all of our collaborating partners and included in this document). Although materials development is required to achieve commercial potential, the clear benefits of the technology if that development were a given is established. Exploration of new transformer types and further work on the Buswell design approach is in the best interest of the public, industry, and the United States. Public benefits accrue from design alternatives that reduce the overall use of energy, but it must be acknowledged that new DOE energy efficiency standards …

ESTIMATED SIL LEVELS AND RISK COMPARISONS FOR RELIEF VALVES AS A FUNCTION OF TIME-IN-SERVICE (open access)

ESTIMATED SIL LEVELS AND RISK COMPARISONS FOR RELIEF VALVES AS A FUNCTION OF TIME-IN-SERVICE

Risk-based inspection methods enable estimation of the probability of spring-operated relief valves failing on demand at the United States Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina. The paper illustrates an approach based on application of the Frechet and Weibull distributions to SRS and Center for Chemical Process Safety (CCPS) Process Equipment Reliability Database (PERD) proof test results. The methodology enables the estimation of ANSI/ISA-84.00.01 Safety Integrity Levels (SILs) as well as the potential change in SIL level due to modification of the maintenance schedule. Current SRS practices are reviewed and recommendations are made for extending inspection intervals. The paper compares risk-based inspection with specific SILs as maintenance intervals are adjusted. Groups of valves are identified in which maintenance times can be extended as well as different groups in which an increased safety margin may be needed.

Force Structure: Assessment of Army Report on Fiscal Year 2011 Progress in Modular Restructuring

Correspondence issued by the Government Accountability Office with an abstract that begins "According to the Army’s Fiscal Year 2011 Report on the Prioritization of Funds for Equipment Readiness and Strategic Capability, issued in September 2011, the report addressed the requirements of the John Warner NDAA for Fiscal Year 2007 rather than the amended requirements stipulated in the Ike Skelton NDAA for Fiscal Year 2011. The report does include some information that addresses aspects of the updated reporting requirements. For example, the 2011 NDAA requires the Army to include a description of the status of the development of doctrine on how modular combat, functional, and support forces will train, be sustained, and fight. In addressing the old reporting requirements in the 2007 NDAA, the Army’s 2011 report discusses modifications to the modularity plan due to finalization of organizational designs and the need to reprioritize due to the emergence of higher-priority force-protection programs. However, the report does not mention the status of the development of doctrine on how modular combat, functional, and support forces will train, be sustained, and fight, as required by the current law."

Gamma discrimination in pillar structured thermal neutron detectors (open access)

Gamma discrimination in pillar structured thermal neutron detectors

Solid-state thermal neutron detectors are desired to replace {sup 3}He tube based technology for the detection of special nuclear materials. {sup 3}He tubes have some issues with stability, sensitivity to microphonics and very recently, a shortage of {sup 3}He. There are numerous solid-state approaches being investigated that utilize various architectures and material combinations. By using the combination of high-aspect-ratio silicon PIN pillars, which are 2 {micro}m wide with a 2 {micro}m separation, arranged in a square matrix, and surrounded by {sup 10}B, the neutron converter material, a high efficiency thermal neutron detector is possible. Besides intrinsic neutron detection efficiency, neutron to gamma discrimination is an important figure of merit for unambiguous signal identification. In this work, theoretical calculations and experimental measurements are conducted to determine the effect of structure design of pillar structured thermal neutron detectors including: intrinsic layer thickness, pillar height, substrate doping and incident gamma energy on neutron to gamma discrimination.

Heritable Genetic Changes in Cells Recovered From Irradiated 3D Tissue Constructs

Combining contemporary cytogenetic methods with DNA CGH microarray technology and chromosome flow-sorting increases substantially the ability to resolve exchange breakpoints associated with interstitial deletions and translocations, allowing the consequences of radiation damage to be directly measured at low doses, while also providing valuable insights into molecular mechanisms of misrepair processes that, in turn, identify appropriate biophysical models of risk at low doses. Specific aims apply to cells recovered from 3D tissue constructs of human skin and, for the purpose of comparison, the same cells irradiated in traditional 2D cultures. The project includes research complementary to NASA/HRP space radiation project.

KC-46 Tanker Aircraft: Acquisition Plans Have Good Features but Contain Schedule Risk (open access)

KC-46 Tanker Aircraft: Acquisition Plans Have Good Features but Contain Schedule Risk

A letter report issued by the Government Accountability Office with an abstract that begins "The KC-46 program has established its acquisition strategy for development and production, including total cost, procurement quantities, and key milestone dates. The program is using a $4.4 billion fixed-price incentive (firm target) development contract that provides contractor incentives to control costs and limits the government’s liability for increased costs over a certain amount. While estimated development costs are currently $900 million higher than the February 2011 contract award amount, the government’s share of these extra costs is limited to about $500 million. The program has identified key performance parameters, but has not yet fully implemented the metrics for tracking their achievement."

Modernizing the Nuclear Security Enterprise: New Plutonium Research Facility at Los Alamos May Not Meet All Mission Needs (open access)

Modernizing the Nuclear Security Enterprise: New Plutonium Research Facility at Los Alamos May Not Meet All Mission Needs

A letter report issued by the Government Accountability Office with an abstract that begins "The estimated cost to construct the CMRR has greatly increased since NNSA’s initial plans, and the project’s schedule has been significantly delayed. According to its most recent estimates prepared in April 2010, NNSA determined that the CMRR will cost between $3.7 billion and $5.8 billion—nearly a six-fold increase from the initial estimate. Construction has also been repeatedly delayed and, in February 2012 after GAO provided its draft report to NNSA for comment, NNSA decided to defer CMRR construction by at least an additional 5 years, bringing the total delay to between 8 and 12 years from NNSA’s original plans. Infrastructure-related design changes and longer-than-expected overall project duration have contributed to these cost increases and delays. GAO’s review of NNSA’s April 2010 cost and schedule estimates for CMRR found that the estimates were generally well prepared, but important weaknesses remain. For example, a high-quality schedule requires a schedule risk analysis that incorporates known risks to predict the level of confidence in meeting a project’s completion date and the amount of contingency time needed to cover unexpected delays. CMRR project officials identified hundreds of risks to the project, …

Multiphase Nano-Composite Coatings for Achieving Energy Optimization (open access)

Multiphase Nano-Composite Coatings for Achieving Energy Optimization

UES Inc. and ANL teamed in this work to develop novel coating systems for the protection of surfaces from thermal degradation mainly in two applications; Machining and Die casting. These coatings were specifically designed for the purpose by incorporating required material phases and the overall architecture, which led to reduce the energy usage and increase efficiency of the operations. Following the UES/ANL'™s feasibility work, the coatings were developed utilizing High power impulse magnetron sputtering (HiPMS) and Large area filtered arc deposition (LAFAD) techniques. Toughness, hardness and oxidation resistance: contrasting qualities have been mixed in the right proportion to attain the suitable material characteristic for the cause. Hafnium diboride (HfB2) based materials provided such a system and its properties were tamed to attain the right combination of toughness and hardness by working on the microstructure and architecture of coatings. An effective interfacing material (graded concentrations of topcoat) was also achieved in this work to provide the required adhesion between the substrate and the coating. Combination of an appropriate bond coat and a functional top coat provided the present thermal degradation resistant coating for cutting tools and die-casting applications. Laboratory level performance tests and industrial level application tests by partner companies (Beta …

Oral History Interview with John Pierce, March 26, 2012 transcript

Oral History Interview with John Pierce, March 26, 2012

The National Museum of the Pacific War presents an oral interview with John Pierce. Pierce registered for the Army in 1942, working as a machinist in a defense plant until he was called to active duty. He deployed to Leyte with the 284th Ordinance Company and set up a mobile machine shop for the repair of amphibious tanks. His unit was unarmed, as they were told they would be far from the action. But he was warned by nearby soldiers to dig a foxhole as quickly as he could, to take cover from snipers. The next day, he found bullet holes in his truck. He also restored equipment after the Battle of Leyte Gulf. Transferring to Okinawa, his company sought refuge in their trucks to survive a typhoon. At the end of the war, Pierce boarded the same ship as Admiral Nimitz for his return trip to the States and had the pleasure of shaking his hand. Pierce was discharged into the Reserves, but the Army misplaced his papers, so he was not recalled to the Korean War. He attended night school on the GI Bill and contined working as a machinist.
