Effects of Seismic Vibrations on the Experimental Gas-Cooled Reactor
The effects of seismic vibrations on the dynamic behavior of a composite system were analyzed. The equations of motion were derived and soIved with special emphasis on determining the resulting stresses. The method of analysis thus developed was applied to the composite structure consisting of the core, pressure vessel, and supporting skirt of the Experimental Gas-Cooled Reactor (EGCR). A system with three degrees of freedom was considered in order to determine the effects of an earthquake of the maximum intensity expected in the area surrounding Oak Ridge, Tennessee. The system of equations of motion was solved both numerically and analytically, and the resonant frequencies were determined. The seismic effect was shown to be small when the frequency of the seismic disturbance coincided with a natural frequency of the system. In particular, the shear stresses in the graphite core were shown to be negligible. (auth)

Recovery of cesium, technetium, rhodium and palladium from stored waste supernates
The results of our assessment of the processing methods and costs for the recovery of cesium, techneium, rhodium, and palladium from aged waste supernates are presented. Guidelines for the assessment of costs are given. Cesium can be readily absorbed from alkaline waste supernates without prior treatment using Linde AW-500, a synthetic zolite. Technetium, present in the supernate as the pertechnetate anion, together with rhodium and palladium, probably present as anionic nitrite complexes, can be absorbed from untreated waste supernates using Dowex 1-X4 or similar anion resins. Although the behavior of cesium and technetium is reasonably well understood, the behavior of the anionic complex that accounts for the presence of rhodium and palladium in this strongly alkaline solution is not well understood. Further work is required before a process can be outlined for the clean separation of rhodium and palladium from the technetium-rhodium-palladium crude fraction sorbed on the anion resin. An assessment of capital and operating costs for the recovery of cesium only, technetium only, or both cesium and technetium are tabulated. No costs are shown for rhodium and palladium, since the technology for their separation is not sufficiently advanced. However, the incremental cost for their separation from technetium is expected …

Flow of particle suspensions through porous media
A new attempt is made to study the mechanisms of particle invasions into porous media. The following subjects are described: A critical survey of the literature indicating that the mechanism of particle invasions is not known in sufficient detail. The pros and cons of existing particle measuring devices are briefly described. Results from a new laboratory study on particle characterizations are given. The results of the laboratory studies on the flow of particle suspensions through porous media (up to 200 md) are discussed. The effects of flow rate and particle concentrations on the amount of damage (i.e., permeability impairment) and depth of penetration (from core inlet towards outlet) are particularly emphasized. Filter methods (e.g., using millipore filter) cannot be used to determine particle invasions into porous medium. Any predictions of the injection problems based on millipore (or any other filter) measurements are useless and should be discarded.

Iran: U.S. Concerns and Policy Responses
Much of the debate over U.S. policy toward Iran has centered on the nature of the current regime; some believe that Iran, a country of about 70 million people, is a threat to U.S. interests because hardliners in Iran's regime dominate and set a policy direction intended to challenge U.S. influence and allies in the region. President George W. Bush, in his January 29, 2002, State of the Union message, labeled Iran part of an "axis of evil" along with Iraq and North Korea. This report discusses the political history of Iran, U.S. strategy in Iran, and the Obama Administration's policies for dealing with Iran, especially with regard to the previous administration's policies.

Department of Homeland Security: Science and Technology Directorate's Expenditure Plan
A letter report issued by the Government Accountability Office with an abstract that begins "In recent years GAO and others have reported on problems in the financial management environment at the Department of Homeland Security's (DHS) Science and Technology Directorate (S&T). S&T was established by the Homeland Security Act of 2002 to, among other things, coordinate the federal government's civilian efforts to identify and develop countermeasures to emerging terrorist threats to our nation. As DHS's primary research and development arm, the directorate is tasked with providing federal, state, local, and tribal officials with state-of-the-art technology and other resources, such as protocols and training procedures for use in responding to, and recovery from, chemical, biological, radiological, nuclear, and explosive attacks. S&T is led by an Under Secretary and has a Chief Financial Officer (CFO) who is responsible for all budgeting and accounting for financial resources. S&T receives funds for research, development, acquisition, and operations. It also receives funds for management and administration that support the operations of the directorate in both headquarters and the field, such as the expenditures for personnel compensation and benefits, travel, and rent. The Department of Homeland Security Appropriations Act, 2007 (Appropriations Act) provided about $973 million …

Mail Order Pharmacies: DOD's Use of VA's Mail Pharmacy Could Produce Savings and Other Benefits
A letter report issued by the Government Accountability Office with an abstract that begins "There has been long-standing congressional interest in whether the Department of Defense (DOD) could use the Department of Veterans Affairs (VA) Consolidated Mail Outpatient Pharmacy (CMOP) system as a cost-effective alternative to beneficiaries picking up outpatient refill prescriptions at DOD military treatment facilities (MTF). To evaluate this possibility, DOD and VA conducted a pilot program in fiscal year 2003 in which a VA CMOP provided outpatient pharmaceutical refill services to DOD beneficiaries served through three MTFs. GAO was asked to estimate cost savings that could be achieved if DOD used VA's CMOP instead of MTF pharmacies for outpatient refill prescriptions, and what other benefits were achieved at the three pilot sites. To estimate potential cost savings and determine what other benefits were achieved, GAO reviewed pilot and pharmacy program documentation and interviewed DOD and VA officials responsible for purchasing and dispensing drugs. GAO also compared drug and administrative costs of dispensing outpatient refills through the fiscal year 2003 pilot program with the costs of dispensing the refills at the three DOD MTFs that participated in the pilot."

Army Working Capital Fund: Army Faces Challenges in Managing Working Capital Fund Cash Balance during Wartime Environment
A letter report issued by the Government Accountability Office with an abstract that begins "The Army Working Capital Fund (AWCF) collected over $16 billion for goods and services provided to customers in fiscal year 2009. Cash generated from sales is used by AWCF to cover its expenses such as paying employees. In light of the Army's changing role in the Middle East, GAO was asked to determine whether (1) AWCF's monthly cash balances fell within the Department of Defense's (DOD) cash requirements for fiscal years 2000 through 2009, (2) the cash transfers resulted in AWCF's monthly cash balances falling below the minimum amount required by DOD, and (3) the AWCF's projected monthly cash balances are expected to fall below DOD's minimum cash requirement for fiscal years 2010 and 2011 and actions the Army can take to manage those balances. To address these objectives, GAO (1) reviewed relevant DOD guidance, (2) obtained and analyzed AWCF budget and accounting reports containing cash information, and (3) interviewed DOD and Army officials."

Nuclear Waste: Plans for Addressing Most Buried Transuranic Wastes Are Not Final, and Preliminary Cost Estimates Will Likely Increase
A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1940s, the development of nuclear weapons technologies has generated transuranic wastes--materials contaminated by certain man-made radioactive elements. These wastes can remain dangerous for thousands of years. Until 1970, the Department of Energy's (DOE) predecessors buried these wastes in shallow pits and trenches. Today, state officials and communities near DOE's major disposal sites have expressed concerns that such wastes might contaminate important ground and surface water resources. GAO was asked to (1) determine the legal requirements and policies affecting DOE's efforts to address transuranic wastes buried before 1970, (2) determine what DOE is doing to address sites where these transuranic wastes are buried, and (3) assess the reliability of DOE's estimated costs to address these sites. We met with federal and state officials at five DOE sites containing buried transuranic wastes, reviewed environmental laws and guidance, and obtained buried waste cleanup cost estimates from each site. In commenting on this report, DOE generally agreed with our findings, and provided some clarifying comments."

Medicare Secondary Payer: Process for Situations Involving Non-Group Health Plans
Testimony issued by the Government Accountability Office with an abstract that begins "The Centers for Medicare & Medicaid Services (CMS) is responsible for protecting the Medicare program's fiscal integrity and ensuring that it pays only for those services that are its responsibility. Medicare Secondary Payer (MSP) provisions make Medicare a secondary payer to certain group health plans (GHP) and non-group health plans (NGHP), which include auto or other liability insurance, no-fault insurance, and workers' compensation plans. CMS has the right to recover Medicare payments made that should have been the responsibility of another payer, but CMS has not always been aware of these MSP situations. In 2007, Congress added mandatory reporting requirements for GHPs and NGHPs that should enable CMS to be aware of MSP situations. CMS reports that mandatory reporting was pushed back from 2009 to 2011 for some NGHPs and from 2009 to 2012 for others, in part due to concerns raised by the industry. GAO was asked to present background information about the MSP process as it pertains to NGHPs. To do this work, GAO reviewed relevant CMS documentation, including MSP regulations, manuals, and user guides, and conducted an interview with CMS related to mandatory reporting and …

Federal Courthouses: Rent Increases Due to New Space and Growing Energy and Security Costs Require Better Tracking and Management
Testimony issued by the Government Accountability Office with an abstract that begins "The judiciary pays over $900 million in rent annually to GSA for court-related space, representing a growing proportion of the judiciary's budget. The judiciary's rent payments are deposited into GSA's Federal Buildings Fund (FBF), a revolving fund used to finance GSA's real property services, including the construction and repair of federal facilities under GSA control. In December 2004, the judiciary requested a $483 million dollar permanent, annual rent exemption which GSA denied, saying that it undermined the intent of FBF and that GSA was unlikely to obtain appropriations to replace lost FBF income. GAO reviewed (1) recent trends in the judiciary's rent and space occupied and (2) challenges that the judiciary faces in managing its rent costs."

Horse Welfare: Action Needed to Address Unintended Consequences from Cessation of Domestic Slaughter
A letter report issued by the Government Accountability Office with an abstract that begins "Since fiscal year 2006, Congress has annually prohibited the use of federal funds to inspect horses destined for food, effectively prohibiting domestic slaughter. The U.S. Department of Agriculture (USDA) is responsible for overseeing the welfare of horses transported for slaughter. Congress directed GAO to examine horse welfare since cessation of domestic slaughter in 2007. GAO examined (1) the effect on the U.S. horse market, if any, since cessation; (2) any impact of these market changes on horse welfare and on states, local governments, tribes, and animal welfare organizations; and (3) challenges, if any, to USDA's oversight of the transport and welfare of U.S. horses exported for slaughter. GAO analyzed horse price and shipping data, and interviewed officials from USDA, state and local governments, tribes, the livestock industry, and animal welfare organizations, and reviewed documents they provided.."

Contract Management: Further Efforts Needed to Sustain VA's Progress in Purchasing Medical Products and Services
A letter report issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) provides healthcare to millions of veterans at VA's medical centers and healthcare facilities across the country. To support veterans, VA manages a Federal Supply Schedule (FSS) program and a national contract program. Both use VA's sizeable buying power to provide VA and other federal agencies discounts on medical products and services. To cover its costs in running the FSS program, VA charges its customers a user fee. Although sales through VA's FSS and national contracts totaled almost $7 billion in fiscal year 2003, concerns have been raised about the efficiency of these contract programs. GAO was asked to determine whether the FSS and national contracts have provided medical products at favorable prices and to identify opportunities to improve purchasing practices and increase savings. GAO was also asked to determine if VA's user fee is sufficient to cover program cost."

Energy Savings: Performance Contracts Offer Benefits, but Vigilance Is Needed to Protect Government Interests
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government is the nation's largest energy consumer, spending, by latest accounting, $3.7 billion on energy for its 500,000 facilities. Upfront funding for energy-efficiency improvements has been difficult to obtain because of budget constraints and competing agency missions. The Congress in 1986 authorized agencies to use Energy Savings Performance Contracts (ESPCs) to privately finance these improvements. The law requires that annual payments for ESPCs not exceed the annual savings generated by the improvements. GAO was asked to identify (1) the extent to which agencies used ESPCs; (2) what energy savings, financial savings, and other benefits agencies expect to achieve; (3) the extent to which actual financial savings cover costs; and (4) what areas, if any, require steps to protect the government's financial interests in using ESPCs."

Children's Health Insurance: Opportunities Exist for Improved Access to Affordable Insurance
A letter report issued by the Government Accountability Office with an abstract that begins "GAO estimates that under the 2010 Patient Protection and Affordable Care Act (PPACA), about three-quarters of approximately 7 million children who were uninsured in January 2009 would be eligible for Medicaid, the State Childrens Health Insurance Program (CHIP), or the new premium tax credit. The remaining children had family incomes too high to be eligible, were noncitizens, or would be ineligible for the premium tax credit because they would be considered to have access to affordable employer-sponsored insurance per the Internal Revenue Services (IRS) proposed affordability standard, in which IRS interpreted PPACA as defining affordability for an employees eligible family members based on the cost of an employee-only plan. Some commenters raised concerns that IRSs interpretation was inconsistent with PPACAs goal of increasing access to affordable health insurance as it does not consider the higher cost of family insurance and could result in some children remaining uninsured. Under PPACA, CHIP is not funded beyond 2015, and states may opt to reduce CHIP eligibility or eliminate programs in fiscal year 2020. Without CHIP, more children could become uninsured. In May 2012, IRS finalized its rule but deferred …

Bottled Water: FDA Safety and Consumer Protections Are Often Less Stringent Than Comparable EPA Protections for Tap Water
A letter report issued by the Government Accountability Office with an abstract that begins "Over the past decade, per capita consumption of bottled water in the United States has more than doubled. With this increase have come several concerns in recent years about the safety, quality, and environmental impacts of bottled water. The Food and Drug Administration (FDA) regulates bottled water under the Federal Food, Drug, and Cosmetic Act as a food and is responsible for ensuring that domestic and imported bottled water is safe and truthfully labeled. Among other things, GAO (1) evaluated the extent to which FDA regulates and ensures the quality and safety of bottled water; (2) evaluated the extent to which federal and state authorities regulate the accuracy of labels and claims regarding the purity and source of bottled water; and (3) identified the environmental and other impacts of bottled water. GAO reviewed FDA data, reports, and requirements for bottled water; conducted a state survey of all 50 states and the District of Columbia; reviewed bottled water labels; and interviewed FDA officials and key experts."

Federal Workers: Results of Studies on Federal Pay Varied Due to Differing Methodologies
A letter report issued by the Government Accountability Office with an abstract that begins "Annual pay adjustments for the General Schedule (GS), the pay system covering the majority of federal workers, are either determined through the process specified in the Federal Employees Pay Comparability Act of 1990 (FEPCA) or set based on percent increases authorized directly by Congress. GS employees receive an across-the-board increase (ranging from 0 to 3.8 percent since FEPCA was implemented) that has usually been made in accordance with a FEPCA formula linking increases to national private sector salary growth. This increase is the same for each employee. GS employees also receive a locality increase that varies based on their location; there were 34 pay localities in 2012. While FEPCA specifies a process designed to reduce federal-nonfederal pay gaps in each locality, in practice locality increases have usually been far less than the recommended amount, which has been over 15 percent in recent years. For 2012, when there was a freeze on annual pay adjustments, the FEPCA process had recommended a 1.1 percent across-the-board increase and an average 18.5 percent locality increase."

Federal Agencies Generally Meet Requirements for Disclosure and Review of Financial Interests Related to Lyme Disease
Correspondence issued by the General Accounting Office with an abstract that begins "Some Lyme disease patients and Lyme disease organizations are concerned that federal agencies and advisors have financial interests that may affect their decisions on the funding of Lyme disease research and the approval of Lyme disease products. These agencies include the Centers for Disease Control (CDC), the National Institutes of Health (NIH), and the Food and Drug Administration (FDA). This report reviews (1) the financial interests that CDC, NIH, and FDA employees and members of advisory committees working on Lyme disease have reported and (2) how these agencies addressed any potential conflicts of interest identified in those reports. GAO found that CDC, NIH, and FDA have generally met the requirements for disclosure and review of financial interests related to Lyme disease. Employees and special government employees (SGE's) working on Lyme disease-related activities have reported financial holdings in, and arrangements with, health sector firms, travel paid for by health sector firms, and patents related to Lyme disease. Program officials and agency officials reviewed the interests of the employees and determined that they did not present conflicts."

Defense Logistics: Lack of a Synchronized Approach between the Marine Corps and Army Affected the Timely Production and Installation of Marine Corps Truck Armor
A letter report issued by the Government Accountability Office with an abstract that begins "The increasing threat of improvised explosive devices (IED) in Iraq has led to widespread interest by Congress and the public regarding the availability of critical force protection equipment. GAO initiated a series of engagements under the Comptroller General's authority to address these concerns. In March 2006, GAO reported on factors that affected the production and installation of armor for the Army's medium and heavy trucks. This engagement examines issues affecting the production and installation of armor for the Marine Corps' medium and heavy trucks. The objectives were to (1) determine the extent to which truck armor was produced and installed to meet identified requirements, (2) identify what factors affected the time to provide truck armor, and (3) identify what actions the Marine Corps and DOD have taken to improve the timely availability of truck armor."

Medicare Part D: Changes in Utilization Similar for Randomly Reassigned and Other Low-Income Subsidy Beneficiaries
Correspondence issued by the Government Accountability Office with an abstract that begins "To help defray out-of-pocket prescription drug costs for limited or low-income Medicare beneficiaries, the Medicare Part D outpatient prescription drug program offers a low-income subsidy (LIS) for eligible beneficiaries. In 2010, about 9.4 million beneficiaries received the LIS--about 40 percent of the approximately 23 million Medicare Part D beneficiaries in that year. Most of the LIS beneficiaries received the full LIS, thus paying no premiums or deductibles as long as they enrolled in so-called "benchmark" stand-alone prescription drug plans (PDP). Benchmark PDPs are those plans with premiums at or below a specified benchmark for a given geographic region, calculated by the Centers for Medicare & Medicaid Services (CMS), the agency within the Department of Health and Human Services (HHS) that administers the Medicare program. Full LIS beneficiaries may also enroll in other Part D plans--either nonbenchmark PDPs or Medicare Advantage prescription drug plans (MAPD)-- but must pay any difference between the premium of the plan in which they choose to enroll and the benchmark for their region. Because plan premiums can change from year to year and because CMS recalculates the premium benchmarks annually, some PDPs may be …
