Acoustic Emission Weld Monitoring of Nuclear Components
Acoustic emission monitoring augments other nondestructive testing methods and is sometimes applicable when other tests cannot be applied. This is, in part, due to the high sensitivity of acoustic emission monitoring. Acoustic emission monitoring is only sensitive to active flaw-growth, however, and will not detect a flaw in equilibrium. This paper describes the application of acoustic emission monitoring to nuclear reactor fuel pin end closure welds and other weldments of the reactor piping.

Pilot plant processing of sodium bifluoride to sodium fluoride pellets
Sodium fluoride (NaF) traps in the PGDP purge cascade presently use NaF pellets to remove residual UF{sub 6} from the gas stream. These pellets are procured from ORGDP which converts sodium bifluoride pellets to NaF by thermal decomposition. Discussions of the possibility of no longer producing pellets at ORGDP, due to oven corrosion problems, led to a pilot plant test at PGDP. This test was designed to examine the feasibility of producing the NaF pellets at PGDP in the event that an alternative source of supply became necessary. Satisfactory pellets were produced without difficulty; however, it was determined that the conversion process could not be readily carried out in the existing NaF traps. Construction of a separate facility with provisions to handle the large quantities of hydrogen fluoride (HF) released during the process would be required to produce pellets at the rate needed. 1 fig., 2 tabs.

Final report for the Chautauqua Radio Workshop Project. July 1, 1980-October 30, 1981
Energy conservation education must reach millions of Americans in order to see any real and immediate decrease in energy consumption. Since our society gets much of its information from the media, this seems like a most effective vehicle for disseminating energy conservation information to the American Public. Radio is listened to by the vast majority of Americans each day of their lives. Radio as a communications medium is an extremely cost effective method of mass communication and education, and is perceived as a personal medium which has great potential to affect a change in the daily energy consumption habits of the public. Call-in radio programs centering around energy conservation are an effective method of presenting informative, energy education programming that provide instantaneous access for listener/consumer participation. The linking of available telephone and radio technology (via call-in radio shows) allows people all over the US, including remote rural areas, access to the latest energy conservation information and renewable energy technolgy.

Information Security: Protecting Personally Identifiable Information
A letter report issued by the Government Accountability Office with an abstract that begins "The loss of personally identifiable information can result in substantial harm, embarrassment, and inconvenience to individuals and may lead to identity theft or other fraudulent use of the information. As shown in prior GAO reports, compromises to such information and long-standing weaknesses in federal information security raise important questions about what steps federal agencies should take to prevent them. As the federal government obtains and processes information about individuals in increasingly diverse ways, properly protecting this information and respecting the privacy rights of individuals will remain critically important. GAO was requested to (1) identify the federal laws and guidance issued to protect personally identifiable information from unauthorized use or disclosure and (2) describe agencies' progress in developing policies and documented procedures that respond to recent guidance from the Office of Management and Budget (OMB) to protect personally identifiable information that is either accessed remotely or physically transported outside an agency's secured physical perimeter. To do so, GAO reviewed relevant laws and guidance, surveyed officials at 24 major federal agencies, and examined and analyzed agency documents, including policies, procedures, and plans. In commenting on a draft of …

Defense Inventory: Control Weaknesses Leave Restricted and Hazardous Excess Property Vulnerable to Improper Use, Loss, and Theft
A letter report issued by the General Accounting Office with an abstract that begins "The Defense Department (DOD) encourages the reuse of excess property, including vehicles, weapons, hand tools, lumber, medical equipment, and furniture. DOD components, civilian federal agencies, and "special programs" have equal priority and first rights to excess property. This report discusses excess property issued to three of 12 special programs--the Military Affiliate Radio System, the Civil Air Patrol, and the 12th Congressional Regional Equipment Center. Between 1995 and 2000, these programs obtained $34 million worth of items that they were not eligible to receive. The three programs were able to obtain the items because the DOD facilities that store the property are not required to verify which items the programs are eligible to receive, and because program officials do not consistently follow applicable guidelines. GAO also noted that the programs' lists of property they are allowed to obtain are not comprehensive because the lists exclude mission-related items similar to those already permitted. Furthermore, these programs did not have reliable records for more than three-quarters of their excess property. Together, the three special programs obtained more than 80,000 hazardous supplies. In many cases, program officials were unaware that …

Cuba Democracy Assistance: USAID's Program Is Improved, but State Could Better Monitor Its Implementing Partners
A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Agency for International Development (USAID) and Department of State (State) provide democracy assistance for Cuba aimed at developing civil society and promoting freedom of information. Typical program beneficiaries include Cuban community leaders, independent journalists, women, youths, and marginalized groups. USAID receives the majority of funding allocated for this assistance, although State has received 32 percent of funding since 2004. In recent years, both USAID and State have provided more funding for program implementation to for-profit and nongovernmental organizations (NGO) with a worldwide or regional focus than to universities and to NGOs that focus only on Cuba. All types of implementing partners, but worldwide or regional organizations in particular, used subpartners to implement program activities under 21 of the 29 awards and contracts that GAO reviewed."

FEDERAL EMPLOYEES' COMPENSATION ACT: Preliminary Observations on Fraud-Prevention Controls
A letter report issued by the Government Accountability Office with an abstract that begins "Our work to this point has identified several promising practices that could help to reduce the risk of fraud within the FECA program. The promising practices link back to fraud-prevention concepts contained in GAOs Fraud Prevention Framework and Standards for Internal Control in the Federal Government, and include agencies use of full-time staff dedicated to the FECA program, periodic reviews of claimants continued eligibility, data analysis for potential fraud indicators, and effective use of investigative resources. These promising practices have already resulted in successful investigations and prosecutions of FECA-related fraud at some agencies, and could help to further enhance the programs fraud-prevention controls. However, our preliminary work has also identified several potential vulnerabilities in the programs design and controls that could increase the risk for fraud. Specifically, we found that limited access to necessary data is potentially reducing agencies ability to effectively monitor claims and wage-loss information. In addition, agencies reliance on self-reported data related to wages and dependent status, lack of a physician selected by the government throughout the process, and difficulties associated with successful investigations and prosecutions all potentially reduce the programs ability to …

Department of State: Additional Steps Are Needed to Improve Strategic Planning and Evaluation of Training for State Personnel
A letter report issued by the Government Accountability Office with an abstract that begins "Because the U.S. Department of State (State) is the lead U.S. foreign affairs agency, its personnel require certain knowledge, skills, and abilities to address the global challenges and security threats facing the United States. State devoted about $255 million to personnel training in fiscal year 2010; the department's Foreign Service Institute (FSI) is the primary training provider for State's more than 66,000 Foreign Service, civil service, and locally employed staff (LE staff) worldwide. GAO was asked to examine (1) State's purpose and structure for training personnel and (2) the extent to which State's training incorporates elements for effective training programs. GAO reviewed and analyzed data and documentation related to the agency's training efforts; completed a training assessment using a tool developed based on prior GAO guidance; and interviewed officials in Washington, D.C., and at 12 overseas posts."

Information Security: Federal Communications Commission Needs to Strengthen Controls over Enhanced Secured Network Project
A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Communications Commission (FCC) did not effectively implement appropriate information security controls in the initial components of the Enhanced Secured Network (ESN) project. Although FCC took steps to enhance its ability to control and monitor its network for security threats, weaknesses identified in the commission's deployment of components of the ESN project as of August 2012 resulted in unnecessary risk that sensitive information could be disclosed, modified, or obtained without authorization. This occurred, in part, because FCC did not fully implement key information security activities during the development and deployment of the initial components of the project. While FCC policy is to integrate security risk management into system life-cycle management activities, the commission instead deployed the initial components of the ESN project without, among other things, first selecting and documenting the security controls, assessing the controls, or authorizing the system to operate. As a result of these deficiencies, FCC's information remained at unnecessary risk of inadvertent or deliberate misuse, improper disclosure, or destruction. Further, addressing these deficiencies could require costly and timeconsuming rework."

Chemical, Biological, Radiological, and Nuclear Risk Assessments: DHS Should Establish More Specific Guidance for Their Use
A letter report issued by the Government Accountability Office with an abstract that begins "Since 2004, DHSs use of its CBRN risk assessments to inform its CBRN response plans has varied, from directly influencing information in the plans to not being used at all. DHS guidance states that response planning and resource decisions should be informed by risk information. GAOs analysis showed that DHS used its CBRN risk assessments to directly inform 2 of 12 CBRN response plans GAO identified because planners considered the risk assessments to be more accurate than earlier DHS planning assumptions. For another 7 of the 12 plans, DHS officials said that the assessments indirectly informed the plans by providing background information prior to plan development. However, GAO could not independently verify this because DHS officials could not document how the risk assessments influenced the information contained in the plans. GAOs analysis found general consistency between the risk assessments and the plans. For the remaining 3 plans, DHS officials did not use the risk assessments to inform the plans; for 2 of the 3 plans DHS officials told GAO they were not aware of the assessments. DHS officials also noted that there was no departmental guidance …

Defense Contracting: Contract Risk a Key Factor in Assessing Excessive Pass-Through Charges
A letter report issued by the Government Accountability Office with an abstract that begins "One-third of the Department of Defense's (DOD) fiscal year 2006 spending on goods and services was for subcontracts. Concerns have been raised among DOD auditors and Congress about the potential for excessive pass- through charges by contractors that add little or no value when work is subcontracted. To better understand this risk, Congress mandated that GAO assess the extent to which DOD may be vulnerable to these charges. This report examines (1) DOD's approach to assessing the risk of excessive pass-through charges when work is subcontracted, (2) the strategies selected private sector companies use to minimize risks of excessive pass-through charges when purchasing goods and services, and (3) DOD's interim rule to prevent excessive pass-through charges. GAO's work is based on analysis of 32 fiscal year 2005 DOD contract actions at 10 DOD top contracting locations and discussions with DOD acquisition policy, audit, and contracting officials, including Defense Contract Audit Agency (DCAA) and Defense Contract Management Agency (DCMA) staff. GAO also interviewed nine selected private sector companies with diverse contracting experience."

Supply Chain Security: Examinations of High-Risk Cargo at Foreign Seaports Have Increased, but Improved Data Collection and Performance Measures Are Needed
A letter report issued by the Government Accountability Office with an abstract that begins "Customs and Border Protection's (CBP) Container Security Initiative (CSI) aims to identify and examine high-risk U.S.-bound cargo at foreign seaports. GAO reported in 2003 and 2005 that CSI helped to enhance homeland security, and recommended actions to strengthen the program. This report updates information and assesses how CBP has (1) contributed to strategic planning for supply chain security, (2) strengthened CSI operations, and (3) evaluated CSI operations. To address these issues, GAO interviewed CBP officials and reviewed CSI evaluations and performance measures. GAO also visited selected U.S. and CSI seaports, and met with U.S. and foreign government officials."

Defense Health: Coordinating Authority Needed for Psychological Health and Traumatic Brain Injury Activities [Reissued on January 27, 2012]
A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal year 2007 through fiscal year 2010, DOD activities for the treatment and research of PH and TBI received more than $2.7 billion. In fiscal year 2007, funding for these activities totaled $900 million; in fiscal year 2008, it was $573.8 million; in fiscal year 2009, $395 million; and in fiscal year 2010, $838.6 million. GAO found, however, that the reports DOD provided to Congress on these activities did not include expenditures, as required by law, and that the obligations data they contained were unreliable. Governmentwide policies call for agencies to have effective internal controls to assure accurate reporting of obligations and expenditures. However, the Office of the Assistant Secretary of Defense for Health Affairs has not developed quality control mechanisms to help ensure that data on PH and TBI activities are complete and accurate. Further, although DOD listed patient care among reported costs, it did not specify what those costs included, making it difficult for decisionmakers and Congress to fully understand the costs."

Mad Cow Disease: Improvements in the Animal Feed Ban and Other Regulatory Areas Would Strengthen U.S. Prevention Efforts
A letter report issued by the General Accounting Office with an abstract that begins "Bovine spongiform encephalopathy (BSE), also known as mad cow disease, has been found in cattle in 23 countries. Countries with BSE have suffered large economic losses because of declines in both beef exports and domestic beef sales. The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) have primary responsibility for preventing the introduction of BSE-contaminated cattle, beef, and cattle-derived products into the United States. GAO found that FDA has not acted promptly to force firms to keep prohibited proteins out of cattle feed and to label animal feed that cannot be fed to cattle. FDA's data on inspections are severely flawed, and FDA is unaware of the full extent of industry compliance. If BSE was discovered in U.S. cattle, many consumers might refuse to buy domestic beef; beef exports could decline dramatically as could sales in related industries, such as hamburger chains and frozen dinner manufacturers. Furthermore, some people might develop mad cow disease if infected cattle were to enter the food supply. The United States acted as many as five years earlier than did other countries to impose controls over imports …

Drug Control: Difficulties in Measuring Costs and Results of Transit Zone Interdiction Efforts
A letter report issued by the General Accounting Office with an abstract that begins "The Defense Department (DOD), the Coast Guard, and the Customs Service all interdict illegal drugs--primarily cocaine--from South America. DOD is the lead agency, but all three agencies play a role in monitoring and detecting shipments of illegal drugs. The Coast Guard is the lead agency for apprehending ships that are smuggling drugs, with Customs providing help as needed. The Coast Guard and Customs share responsibility for apprehending aircraft involved in drug-smuggling. GAO could not identify the funds obligated and the number of flight hours and ship days used for drug interdiction in the drug transit zone because the three agencies do not routinely track this information. The results tracked by the three agencies to demonstrate their effectiveness of their drug interdiction efforts in the transit zone varied according to whether they focused on drug seizures or results of detection and monitoring and whether they were specific to the transit zone. Agencies can use several controls to ensure the accuracy of their own cocaine seizure data, such as assigning unique identification numbers to each seizure and headquarters review of data from field units. Although two interagency data …

DOJ's Public Integrity Section: Case Management Policies Followed, but Closing Some Matters Took Too Long
A chapter report issued by the General Accounting Office with an abstract that begins "GAO issued a report on the results of its management and operational review of the Department of Justice's (DOJ) Public Integrity Section (PI). Specifically, GAO reviewed: (1) PI's organization, staffing, workload, and results; (2) the policies and procedures in place to govern PI's case management practices and its compliance with those policies and procedures, and; (3) DOJ's management oversight of those practices. PI was staffed with 30 attorneys, including a chief and three deputies. Between 1995 and 2000, PI opened 1,013 matters for investigation and filed 163 cases for the court. The conviction rate was 94 percent for cases prosecuted during this time. DOJ's written policies and procedures outlined how PI should manage its caseloads. For the closed cases and matters GAO reviewed, PI generally complied with DOJ's procedures. However, GAO found that, in some cases, PI did not resolve issues in a timely manner. As a result, some matters remained opened for extended periods. DOJ also had policies and procedures in place to ensure that PI's case management practices were subject to management oversight. These oversight practices included documented reviews, daily interactions with attorneys, and …

An Analysis of the Price Elasticity of Demand for Household Appliances
This report summarizes our study of the price elasticity of demand for home appliances, including refrigerators, clothes washers, and dishwashers. In the context of increasingly stringent appliance standards, we are interested in what kind of impact the increased manufacturing costs caused by higher efficiency requirements will have on appliance sales. We begin with a review of existing economics literature describing the impact of economic variables on the sale of durable goods.We then describe the market for home appliances and changes in this market over the past 20 years, performing regression analysis on the shipments of home appliances and relevant economic variables including changes to operating cost and household income. Based on our analysis, we conclude that the demand for home appliances is price inelastic.
