The overall objective of the EM-31 Rheological Modifiers and Wetting Agents program is to utilize commercially available rheology modifiers to increase the solids fraction of radioactive sludge based waste streams, resulting in an increase in throughput and decreasing the overall processing time. The program first investigates the impact of rheology modifiers on slurry simulants and then utilizes the most effective rheology modifiers on radioactive slurries. The work presented in this document covers the initial investigation of rheology modifier testing with simulants. This task is supported by both the Savannah River National Laboratory (SRNL) and Pacific Northwest National Laboratory (PNNL). The SRNL EM-31 task, for this year, was to investigate the use of rheology modifiers on simulant Defense Waste Processing Facility (DWPF) melter feeds. The task is to determine, based on the impact of the rheology modifier, if there are rheology modifiers that could reduce the water content of the slurry going to the DWPF melter, hence increasing the melt rate by decreasing the water loading. The rheology modifier in essence would allow a higher solids content slurry to have the same type of rheology or pumpability of a lower solids slurry. The modifiers selected in this report were determined based …

A letter report issued by the Government Accountability Office with an abstract that begins "The 491 U.S. coal-fired power plants are the largest unregulated industrial source of mercury emissions nationwide, annually emitting about 48 tons of mercury--a toxic element that poses health threats, including neurological disorders in children. In 2000, the Environmental Protection Agency (EPA) determined that mercury emissions from these sources should be regulated, but the agency has not set a maximum achievable control technology (MACT) standard, as the Clean Air Act requires. Some power plants, however, must reduce mercury emissions to comply with state regulations or consent decrees. After managing a long-term mercury control research and development program, the Department of Energy (DOE) reported in 2008 that systems that inject sorbents--powdery substances to which mercury binds--into the exhaust from boilers of coal-fired power plants were ready for commercial deployment. Tests of sorbent injection systems, the most mature mercury control technology, were conducted on a variety of coal types and boiler configurations--that is, on boilers using different air pollution control devices. In this context, GAO was asked to examine (1) reductions achieved by mercury control technologies and the extent of their use at power plants, (2) the cost of …

Between 1951 and 1992, underground nuclear weapons testing was conducted at 828 sites on the Nevada Test Site, Nye County, Nevada. Prior to and following these nuclear tests, holes were drilled and mined to collect rock samples. These samples are organized and stored by depth of borehole or drift at the U.S. Geological Survey Core Library and Data Center at Mercury, Nevada, on the Nevada Test Site. From these rock samples, rock properties were analyzed and interpreted and compiled into project files and in published reports that are maintained at the Core Library and at the U.S. Geological Survey office in Henderson, Nevada. These rock-sample data include lithologic descriptions, physical and mechanical properties, and fracture characteristics. Hydraulic properties also were compiled from holes completed in the water table. Rock samples are irreplaceable because pre-test, in-place conditions cannot be recreated and samples cannot be recollected from the many holes destroyed by testing. Documenting these data in a published report will ensure availability for future investigators.

This report provides a brief overview of the European Union's (EU) accession process; Turkey's path to EU membership; the impact of the Cyprus problem; and a review of the United States' interest in Turkey's future in the European Union.

This report tracks the status of ongoing legislative action and debate related to Federal Aviation Administration (FAA) reauthorization. It is organized into six major program areas: aviation system finance; airport financing; FAA management and organizational issues; system capacity and safety; environmental issues; and airline industry issues. In several cases, provisions that appear in various unrelated sections of proposed legislation have been rearranged in this report in an effort to group and discuss related items in an issue-driven or programmatic context. Since this report is primarily written as a means of communicating key legislative provisions under consideration in the ongoing FAA reauthorization process, it does not go into detail regarding the specific policy issues behind these legislative proposals.

This report discusses the Improper Payments Information Act (IPIA), which signed into law in 2002 requires agencies to identify each year programs and activities vulnerable to significant improper payments, to estimate the amount of overpayments or underpayments, and to report to Congress on steps being taken to reduce such payments.

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2009, the federal government planned to spend about $71 billion on information technology (IT) investments. To more effectively manage such investments, in 2005 the Office of Management and Budget (OMB) directed agencies to implement earned value management (EVM). EVM is a project management approach that, if implemented appropriately, provides objective reports of project status, produces early warning signs of impending schedule delays and cost overruns, and provides unbiased estimates of anticipated costs at completion. GAO was asked to assess selected agencies' EVM policies, determine whether they are adequately using earned value techniques to manage key system acquisitions, and eval- uate selected investments' earned value data to determine their cost and schedule performances. To do so, GAO compared agency policies with best practices, performed case studies, and reviewed documenta- tion from eight agencies and 16 major investments with the highest levels of IT development-related spending in fiscal year 2009."

This report discusses the increasing international pressure on Iran to curb its nuclear program and how that pressure discourages foreign firms from investing in Iran's energy sector, hindering Iran's efforts to expand oil production. This report discusses the history and progress of the formal U.S. effort to curb energy investment in Iran, which began with the Iran Sanctions Act (ISA) in 1996.

The Department of Defense (DOD) is placing an increased planning and budgeting emphasis on irregular warfare (IW) operations, such as counterinsurgency operations. In addition, counterterrorism (CT) operations have been a DOD area of emphasis since the terrorist attacks of September 11, 2001. The Navy for several years has carried out a variety of IW and CT activities, and has taken some steps in recent years to strengthen its ability to conduct such activities. This report discusses these activities and potential oversight issues raised by them.

The Stockpile Stewardship Program (SSP) is a single, highly integrated technical program for maintaining the surety and reliability of the U.S. nuclear stockpile. The SSP uses past nuclear test data along with current and future non-nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. It includes stockpile surveillance, experimental research, development and engineering (D&E) programs, and an appropriately scaled production capability to support stockpile requirements. This integrated national program requires the continued use of current facilities and programs along with new experimental facilities and computational enhancements to support these programs. The Advanced Simulation and Computing Program (ASC) is a cornerstone of the SSP, providing simulation capabilities and computational resources to support the annual stockpile assessment and certification, to study advanced nuclear weapons design and manufacturing processes, to analyze accident scenarios and weapons aging, and to provide the tools to enable stockpile Life Extension Programs (LEPs) and the resolution of Significant Finding Investigations (SFIs). This requires a balanced resource, including technical staff, hardware, simulation software, and computer science solutions. In its first decade, the ASC strategy focused on demonstrating simulation capabilities of unprecedented scale in three spatial dimensions. In its second decade, ASC is …
