A letter report issued by the Government Accountability Office with an abstract that begins "The Census Bureau (Bureau) has made progress in researching and testing information technology (IT) options for the 2020 Decennial Census, but several of the supporting projects lack schedules and plans, and it is uncertain whether they will be completed in time to inform the decision on the operational design for the 2020 census, planned for September 2015. Specifically, it has begun research on six IT-related projects, such as using the Internet for survey response and using employees' personal smartphones to collect census data. However, four of the projects lacked finalized schedules, and three lacked plans for gauging progress. Moreover, the two projects with completed schedules are not estimated to be completed until after the September 2015 design decision date (see figure)."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO found examples of improper payments and indicators of potential fraud in the Federal Employees' Compensation Act (FECA) program, which could be attributed, in part, to oversight and data-access issues. GAO found examples of claimants' receiving overlapping FECA and unemployment insurance (UI) benefits, which may be allowable under certain circumstances, but could also be erroneous. GAO also found that FECA program requirements allow claimants to receive earnings, and earnings increases, without necessarily resulting in adjustment of FECA compensation. For example, of the 32 FECA case files reviewed, GAO found five instances where an individual's wage-earning capacity (WEC), which is used to determine FECA benefits, was not adjusted even though the individual earned substantially more than the wage that was originally used to calculate the WEC. In addition, two FECA claimants continued to receive privateemployment salaries that were not subject to their WEC calculation. This is because, as currently written, program procedures allow claimants to receive increases in earnings, in certain circumstances, without adjustments to FECA compensation, and current law allows for claimants' earnings from dissimilar concurrent private employment at the time of injury to be exempt …

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has played an active role in helping to reform financial regulations to address weaknesses revealed by the 2007-2009 financial crisis. According to Treasury officials, during the acute phase of the crisis, the United States proposed elevating the Group of Twenty (G20) forum—representing 19 countries (including the United States) and the European Union—from the level of finance ministers and central banks to the level of heads of state or government. In 2008, the U.S. President and other G20 leaders held their first summit in Washington, D.C., in part to establish a framework to help prevent financial crises. The G20 leaders established principles for financial regulatory reform and agreed on a series of financial reforms, which they have revised or expanded at subsequent summits. To implement their reforms, the G20 leaders generally have called on their national authorities—finance ministries, central banks, and regulators—and international bodies, including the Financial Stability Board (FSB) and standard setting bodies, such as the Basel Committee on Banking Supervision. In 2009, the G20 leaders established FSB to coordinate and promote implementation of the financial reforms, which typically involves standard setting bodies …

A letter report issued by the Government Accountability Office with an abstract that begins "While the primary responsibility for protecting the nation's communications networks belongs to private-sector owners and operators, federal agencies also play a role in support of their security, as well as that of critical components supporting the Internet. Specifically, private-sector entities are responsible for the operational security of the networks they own, but the Federal Communications Commission (FCC) and the Departments of Homeland Security (DHS), Defense, and Commerce have regulatory and support roles, as established in federal law and policy, and have taken a variety of related actions. For example, FCC has developed and maintained a system for reporting network outage information; DHS has multiple components focused on assessing risk and sharing threat information; Defense and DHS serve as co-chairs for a committee on national security and emergency preparedness for telecommunications functions; and Commerce has studied cyber risks facing the communications infrastructure and participates in standards development. However, DHS and its partners have not yet initiated the process for developing outcome-based performance measures related to the cyber protection of key parts of the communications infrastructure. Outcome-based metrics related to communications networks and critical components supporting the Internet …

A letter report issued by the Government Accountability Office with an abstract that begins "The Army has a standard process to manage litigation costs of its Military Housing Privatization Initiative (MHPI) projects that are not accounted for in the annual budget process. Army officials indicated that there is one case between four Army MHPI projects and Pinnacle Property Management (Pinnacle) that met the dollar threshold criteria and that would have been approved through this process. However, Army officials did not use the standard process because the Army determined that it needed to limit access to Pinnacle litigation information to avoid disclosing any information material to the litigation strategy. As a result, the Army used an alternative process to review and approve litigation costs for Pinnacle that is consistent with MHPI operating agreements. Had the standard process been followed, litigation and litigation cost information would have been shared with the MHPI projects construction company, Clark Realty Capital (Clark), and four different offices within the Army. Army and Clark officials decided to use the alternative process allowed by the MHPI’s operating agreements so that fewer personnel would be aware of ongoing litigation information involving Pinnacle. The alternative process allows the Army and …

The Defense Nuclear Facilities Safety Board (DNFSB) has recently questioned the appropriate value for tritium deposition velocity used in the MELCOR Accident Consequence Code System Ver. 2 (Chanin and Young 1998) code when estimating bounding dose (95th percentile) for safety analysis (DNFSB 2011). The purpose of this paper is to provide appropriate, defensible values of the tritium deposition velocity for use in Savannah River Site (SRS) safety analyses. To accomplish this, consideration must be given to the re-emission of tritium after deposition. Approximately 85% of the surface area of the SRS is forested. The majority of the forests are pine plantations, 68%. The remaining forest area is 6% mixed pine and hardwood and 26% swamp hardwood. Most of the path from potential release points to the site boundary is through forested land. A search of published studies indicate daylight, tritiated water (HTO) vapor deposition velocities in forest vegetation can range from 0.07 to 2.8 cm/s. Analysis of the results of studies done on an SRS pine plantation and climatological data from the SRS meteorological network indicate that the average deposition velocity during daylight periods is around 0.42 cm/s. The minimum deposition velocity was determined to be about 0.1 cm/s, which …

Laser welding and post weld laser treatment of modified 9Cr-1MoVNb steels (Grade P91) were performed in this preliminary study to investigate the feasibility of using laser welding process as a potential alternative to arc welding methods for solving the Type IV cracking problem in P91 steel welds. The mechanical and metallurgical testing of the pulsed Nd:YAG laser-welded samples shows the following conclusions: (1) both bead-on-plate and circumferential butt welds made by a pulsed Nd:YAG laser show good welds that are free of microcracks and porosity. The narrow heat affected zone has a homogeneous grain structure without conventional soft hardness zone where the Type IV cracking occurs in conventional arc welds. (2) The laser weld tests also show that the same laser welder has the potential to be used as a multi-function tool for weld surface remelting, glazing or post weld tempering to reduce the weld surface defects and to increase the cracking resistance and toughness of the welds. (3) The Vicker hardness of laser welds in the weld and heat affected zone was 420-500 HV with peak hardness in the HAZ compared to 240 HV of base metal. Post weld laser treatment was able to slightly reduce the peak hardness …

This short summary of previously published data was compiled to provide the actual in-situ gauge data to allow modeling of these experiments. Although the purpose here is to fulfill a deliverable for a JOWOG 9 Focused Exchange (09-006), it is just as applicable to other exchanges as well. The TATB materials described here are Ultra Fine (UF) TATB and LX-17 (92.5% TATB and 7.5% Kel-F by weight), with the details of the experiments provided in the prior publications. The data is provided in the appendices of the document, but will be provided electronically as text files due to being amenable to importing into the code in that manner for comparison.

This STOMP (Subsurface Transport Over Multiple Phases) guide document describes the theory, use, and application of the STOMP-CO2 and STOMP-CO2e operational modes. These operational modes of the STOMP simulator are configured to solve problems involving the sequestration of CO2 in geologic saline reservoirs. STOMP-CO2 is the isothermal version and STOMP-CO2e is the nonisothermal version. These core operational modes solve the governing conservation equations for component flow and transport through geologic media; where, the STOMP-CO2 components are water, CO2 and salt and the STOMP-CO2e operational mode also includes an energy conservation equation. Geochemistry can be included in the problem solution via the ECKEChem (Equilibrium-Conservation-Kinetic-Equation Chemistry) module, and geomechanics via the EPRMech (Elastic-Plastic-Rock Mechanics) module. This addendum is designed to provide the new user with a full guide for the core capabilities of the STOMP-CO2 and -CO2e simulators, and to provide the experienced user with a quick reference on implementing features. Several benchmark problems are provided in this addendum, which serve as starting points for developing inputs for more complex problems and as demonstrations of the simulator’s capabilities.

The atmospheric release of tritium oxide (HTO) potentially impacts human health, typically through inhalation or absorption. Due to HTO's similarity to water, vegetation will absorb HTO by solution in the leaf water and then re-emit it, creating a number of secondary sources of HTO. Currently, models used for emergency response at Savannah River Site incorporate the transport and deposition of HTO but do not provide estimates for its potential re-emission from vegetation or soil surface though re-emission could result in prolonged exposure and greater than predicted dose for an individual downwind. A simple model of HTO transport, deposition and re-emission has been developed to examine the potential increase in exposure and dose. The model simulates an initial release of HTO that moves with a mean wind and expands through diffusion as a Gaussian puff. Deposition is modeled using previous estimates of deposition velocity for HTO and re-emission is modeled using a time constant that describes how quickly HTO is transferred between the surface and atmosphere. Additional puffs are created to simulate re-emission of HTO as well as horizontal diffusion across model grid cells. An evaluation of field data indicates that the use of a re-emission module tends to improve model …

This investigation evaluated mass extraction rate from individual wells associated with the Western Sector Treatment System (formerly known as the DUS-II project). This was critical since each individual well can have a radius of influence in excess of 100-ft when operating using an active extraction system. Future soil vapor extraction should use the existing active extraction system, supplemented with deployment of passive extraction where appropriate.
