1.5D Quasilinear Model for Alpha Particle-TAE Interaction in ARIES ACT-I
We study the TAE interaction with alpha particle fusion products in ARIES ACT-I using the 1.5D quasilinear model. 1.5D uses linear analytic expressions for growth and damping rates of TAE modes evaluated using TRANSP pro les to calculates the relaxation of pressure pro les. NOVA- K simulations are conducted to validate the analytic dependancies of the rates, and to normalize their absolute value. The low dimensionality of the model permits calculating loss diagrams in large parameter spaces.

8(a) Program: Fourteen Ineligible Firms Received $325 Million in Sole-Source and Set-Aside Contracts
A letter report issued by the Government Accountability Office with an abstract that begins "The Small Business Administration (SBA) helps socially and economically disadvantaged small businesses gain access to federal contracting opportunities through its 8(a) program. To participate, firms must be at least 51 percent owned and controlled by an individual who meets SBA's criteria of socially and economically disadvantaged. The firm must also qualify as a small business. Once certified, 8(a) firms are eligible to receive sole-source and set-aside contracts for up to 9 years. GAO was asked to (1) determine whether ineligible firms are participating in the 8(a) program, (2) proactively test SBA's controls over the 8(a) application process, and (3) determine what vulnerabilities, if any, exist in SBA's fraud prevention system. To identify cases, GAO reviewed SBA data and complaints to GAO's fraud hotline. To perform its proactive testing, GAO created four bogus businesses and applied for 8(a) certification. GAO did not attempt to project the extent of fraud and abuse in the program."

100% DD Energy Model Update
The Miami Science Museum energy model has been used during DD to test the buildingâs potential for energy savings as measured by ASHRAE 90.1-2007 Appendix G. This standard compares the designed buildingâs yearly energy cost with that of a code-compliant building. The building is currently on track show 20% or better improvement over the ASHRAE 90.1-2007 Appendix G baseline; this performance would ensure minimum compliance with both LEED 2.2 and current Florida Energy Code, which both reference a less strict version of ASHRAE 90.1. In addition to being an exercise in energy code compliance, the energy model has been used as a design tool to show the relative performance benefit of individual energy conservation measures (ECMs). These ECMs are areas where the design team has improved upon code-minimum design paths to improve the energy performance of the building. By adding ECMs one a time to a code-compliant baseline building, the current analysis identifies which ECMs are most effective in helping the building meet its energy performance goals.

200-BP-1 Prototype Hanford Barrier -- 15 Years of Performance Monitoring
Monitoring is an essential component of engineered barrier system design and operation. A composite capacitive cover, including a capillary break and an evapotranspiration (ET) barrier at the Hanford Site, is generating data that can be used to help resolve these issues. The prototype Hanford barrier was constructed over the 216-B-57 Crib in 1994 to evaluate surface-barrier constructability, construction costs, and physical and hydrologic performance at the field scale. The barrier has been routinely monitored between November 1994 and September 1998 as part of a Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) treatability test of barrier performance for the 200 BP 1 Operable Unit. Since FY 1998, monitoring has focused on a more limited set of key water balance, stability, and biotic parameters. In FY 2009, data collection was focused on: (1) water-balance monitoring, consisting of precipitation, runoff, soil moisture storage, and drainage measurements with evapotranspiration calculated by difference; (2) stability monitoring, consisting of asphalt-layer-settlement, basalt-side-slope-stability, and surface-elevation measurements; (3) vegetation dynamics; and (4) animal use. September 2009 marked 15 years since the start of monitoring and the collection of performance data. This report describes the results of monitoring activities during the period October 1, 2008, through September …

2010 Census: Cooperation with Enumerators Is Critical to a Successful Headcount
Testimony issued by the Government Accountability Office with an abstract that begins "On May 1, 2010, the U.S. Census Bureau (Bureau) will launch its massive follow-up effort with the roughly 48 million households that did not mail back their census forms (130 million forms were delivered). As part of this nonresponse follow-up effort, over 600,000 enumerators will fan out across the country, personally contacting nonresponding housing units as many as six times in an effort to ensure everyone is counted. As requested, GAO's testimony in Los Angeles (L.A.) focuses on the importance of census participation, paying particular attention to (1) the Bureau's preparedness for nonresponse follow-up in terms of workload and staffing levels, (2) why it will be critical for Angelenos and others across the country to cooperate with enumerators during nonresponse follow-up, and (3) key steps the Bureau needs to take moving forward to ensure nonresponse follow-up is timely and accurate. The testimony is based on previously issued and ongoing GAO work."

2010 Thin Film & Small Scale Mechanical Behavior Gordon Research Conference
Over the past decades, it has been well established that the mechanical behavior of materials changes when they are confined geometrically at least in one dimension to small scale. It is the aim of the 2010 Gordon Conference on 'Thin Film and Small Scale Mechanical Behavior' to discuss cutting-edge research on elastic, plastic and time-dependent deformation as well as degradation mechanisms like fracture, fatigue and wear at small scales. As in the past, the conference will benefit from contributions from fundamental studies of physical mechanisms linked to material science and engineering reaching towards application in modern applications ranging from optical and microelectronic devices and nano- or micro-electrical mechanical systems to devices for energy production and storage. The conference will feature entirely new testing methodologies and in situ measurements as well as recent progress in atomistic and micromechanical modeling. Particularly, emerging topics in the area of energy conversion and storage, such as material for batteries will be highlighted. The study of small-scale mechanical phenomena in systems related to energy production, conversion or storage offer an enticing opportunity to materials scientists, who can provide new insight and investigate these phenomena with methods that have not previously been exploited.

2011 Annual Health Physics Report for the HEU transparency Program
During the 2008 calendar year, Lawrence Livermore National Laboratory (LLNL) provided health physics support for the Highly Enriched Uranium (HEU) Transparency Program for external and internal radiation protection. They also provided technical expertise related to BDMS radioactive sources and Russian radiation safety regulatory compliance. For the calendar year 2008, there were 158 person-trips that required dose monitoring of the U.S. monitors. Of the 158 person-trips, 148 person-trips were SMVs and 10 person-trips were Transparency Monitoring Office (TMO) trips. There were 6 monitoring visits by TMO monitors to facilities other than UEIE and 8 to UEIE itself. There were three monitoring visits (source changes) that were back-to-back with a total of 24 monitors. LLNL's Hazard Control Department laboratories provided the dosimetry services for the HEU Transparency monitors. In 2008, the HEU Transparency activities in Russia were conducted in a radiologically safe manner for the HEU Transparency monitors in accordance with the expectations of the HEU Transparency staff, NNSA and DOE. The HEU Transparency now has thirteen years of successful experience in developing and providing health and safety support in meeting its technical objectives.

2011 Lobbying Disclosure: Observations on Lobbyists' Compliance with Disclosure Requirements
A letter report issued by the Government Accountability Office with an abstract that begins "Most lobbyists were able to provide documentation to demonstrate compliance with disclosure requirements. This finding is similar to GAOs results from prior reviews. There are no specific requirements for lobbyists to create or maintain documentation related to disclosure reports they file under the Lobbying Disclosure Act of 1995 as amended (LDA). Nonetheless, and similar to last years results, for two key elements of the reports (income and expenses), GAO estimates that lobbyists could provide documentation to support approximately 93 percent of the disclosure reports for the third and fourth quarters of 2010 and the first and second quarters of 2011. According to documentation lobbyists provided for income and expenses, GAO estimates that the amounts disclosed were properly reported and supported for 63 percent of the quarterly lobbying disclosure (LD-2) reports. For lobbyists and lobbying firms listed on the LD-2 report, an estimated 86 percent filed year-end 2010 or midyear 2011 reports of federal political campaign contributions (LD-203) reports as required. For LD-203 political contributions reports, GAO estimates that a minimum of 4 percent of all LD-203 reports omitted one or more reportable political contributions that were …

2011 PERFORMANCE ASSESSMENT COMMUNITY OF PRACTICE TECHNICAL EXCHANGE - SUMMARY
The Performance Assessment Community of Practice (PA CoP) was developed in 2008 to improve consistency and quality in the preparation of performance assessments (PAs) and risk assessments across the Department of Energy (DOE) Complex. The term, PA, is used to represent all of these modeling applications in this report. The PA CoP goals are to foster the exchange of information among PA practitioners and to share lessons learned from PAs conducted for DOE, commercial disposal facilities, and international entities. Technical exchanges and workshops are a cornerstone of PA CoP activities. Previous technical exchanges have addressed Engineered Barriers (2009 - http://www.cresp.org/education/workshops/pacop/), the Advanced Simulation Capability for Environmental Management and the Cementitious Barriers Partnership (2010 - http://srnl.doe.gov/copexchange/links.htm). Each technical exchange also includes summary presentations regarding activities at DOE, the Nuclear Regulatory Commission (NRC) and other organizations (e.g., International Atomic Energy Agency (IAEA)) as well as a number of presentations from selected sites to provide insight and perspective from on-going modeling activities. Through the deployment of PA Assistance Teams, the PA CoP has also been engaged in the development of new PAs across the DOE Complex. As a way of improving consistency in the preparation of new PAs, the teams provide technical advice …

3013 DE INNER CONTAINER CLOSURE WELD CORROSION EVALUATION
Destructive evaluation (DE) of 3013 containers is one part of the U. S. Department of Energy Integrated Surveillance Program. During standard DE of 3013 containers, visual examinations for pitting and stress corrosion cracking (SCC) are performed on the accessible surfaces of the outer, inner, and convenience containers, which make up the 3013 container. As a result of 3013 DE additional analysis, the area near the inner container closure weld has been identified as being a region of increased corrosion susceptibility, which may provide a pathway for corrosive gases to the outer container. This area has a higher residual stress, an altered microstructure, and less corrosion resistant weld oxides as a result of the welding process as well as a lower temperature than other areas of the container, which may increase the absorption of moisture on the surface. The deposition of moisture in this stressed region could lead to pitting and stress corrosion cracking. During FY2013, the inner container closure weld area was more closely evaluated on several archived samples from DE containers. These containers included FY09 DE2, FY12 DE4, FY12 DE6 and FY12 DE7 and the Hanford High Moisture Container. The additional examinations included visual observations with a stereomicroscope, scanning …
