Molten fluoride salts, because of their radiation stability and ability to contain both Th and U, offer important advantages as high-temperature fuel solutions for nuclear reactors and as media suitable for nuclear fuel processing. Both applications have stimulated experimental and theoretical studies of the corrosion processes by which molten salt mixtures attack potential reactor materials. Corrosion experiments with fluoride salts which were conducted in support of the Molten-Salt Reactor E xperiment and analytical methods employed to interpret corrosion and masstransfer behavior in this reactor system are discussed. The products of corrosion of metals by fluoride melts are soluble in the molten salt; accordingly passivation is precluded and corrosion depends directly on the thermodynamic driving force of the corrosion reactions. Compatibility of the container metal and molten salt, therefore, demands the selection of salt constituents which are not appreciably reduced by useful structural alloys and the development of container materials whose components are in near thermodynamic equilibrium with the salt medium. Utilizing information gained in corrosion testing of commercial alloys and in fundamental interpretations of the corrosion process, an alloy development program was conducted to provide a high temperature container material that combined corrosion resistance with useful mechanical properties. The program …

This report is an examination of the equipment preferences and decision-making methodology of the coal industry. The prime purpose is to indicate directions in which equipment research might proceed and also to indicate methods by which investment in new, more productive mining equipment could be encouraged. In addition to this, an investigation of the research and development decisions of major mining equipment manufacturers was conducted. The findings can best be condensed into three categories: needs for equipment in underground mining, needs for equipment in surface mining, and the purchase decision by coal mine operators.

This report discusses the military justice system and legislation and judicial decisions regarding it.

A method for calculating Cherenkov radiation intensity from an initial electron energy distribution is presented. The Cherenkov radiation intensity from 1 curie of Sr/sup 90/ in secular equilibrium with Y/sup 90/ in water was calculated from the beta energy spectrum to illustrate the use of the method for a pure beta emitter. The Cherenkov radiation intensity from 1 curie of Co/sup 60/ in water was calculated from the Compton electron energy spectrum to illustrate the use of the method for a gamma emitter. The steps necessary to obtain the Compton electron energy spectrum from a gamma emitter are indicated. (auth)

Beryllium is a metal sensitive to machining damage, causing a loss in mechanical properties. Since some mechanical abrading is often used in surface preparation for mounting strain gages, it is desirable to know whether the abrading produces flaws. Metallographic study of beryllium subjected to four different surface preparation methods was carried out. It was determined that the gentle abrading necessary for affixing strain gages produced a negligible density and depth of flaws and did not lower the mechanical properties. 5 figures, 2 tables.

Presently available information on austenitic Fe-Cr-Ni stainless steel plate, welds, and castings for service below 77 K are reviewed with the intent (1) of developing systematic relationships between mechanical properties, composition, microstructure, and processing, and (2) of assessing the adequacy of these data bases in the design, fabrication, and operation of engineering systems at 4 K.

A letter report issued by the Government Accountability Office with an abstract that begins "The four Department of Defense (DOD) components GAO examined have active processes for referring identified cases of contractor misconduct for appropriate action, including suspension or debarment. The components identify numerous cases of actual or alleged contractor misconduct each year from various internal and external sources. The figure below shows the process for identifying and referring cases to the suspension and debarment official for consideration."

A letter report issued by the Government Accountability Office with an abstract that begins "For the past 2 years, the Department of Defense (DOD) has been implementing the Weapon Systems Acquisition Reform Act (Reform Act) requirements for systems engineering and developmental testing. These activities are important to DOD's ability to control acquisition costs, which increased by $135 billion over the past 2 years for 98 major defense acquisition programs. GAO was asked to determine (1) DOD's progress in implementing the Reform Act's requirements and (2) whether there are challenges at the military service level that could affect their systems engineering and developmental testing activities. To do this, GAO analyzed implementation status documents, discussed developmental testing office concerns with current and former DOD officials, and analyzed military service workforce growth plans and test range funding data.."

A letter report issued by the Government Accountability Office with an abstract that begins "Congress has appropriated billions of dollars for equipment repair, replacement, and recapitalization, collectively known as equipment reset. Because of the potential for equipment reset costs to affect the Department of Defense's (DOD) future budget requirements and related readiness concerns, GAO initiated this review under the Comptroller General's authority. GAO's objectives were to determine the extent to which the Army and Marine Corps (1) track and report equipment reset expenditures in a way that confirms that funds appropriated for reset are expended for that purpose and (2) can be assured that their reset strategies will sustain equipment availability while meeting ongoing operational requirements. GAO reviewed equipment reset policies and analyzed related budget data."

A letter report issued by the Government Accountability Office with an abstract that begins "Little is known about lithium-7 production in China and Russia and whether their supplies can meet future domestic demand. According to industry representatives, China and Russia produce enough lithium-7 to meet demand from U.S. pressurized water reactors, a type of commercial nuclear power reactor that requires lithium-7 for safe operation. However, China's continued supply may be reduced by its own growing demand, according to an expert that is familiar with China's plans. Specifically, China is building several pressurized water reactors and developing a new type of reactor that will require 1,000s of kilograms of lithium-7 to operate, rather than the 300 kilograms needed annually for all 65 U.S. pressurized water reactors. Relying on two producers of lithium-7 leaves U.S. pressurized water reactors vulnerable to lithium-7 supply disruptions."

A letter report issued by the Government Accountability Office with an abstract that begins "The cost of administering human service programs has been a long-standing concern among policy makers interested in ensuring that federal programs are run in a cost-efficient manner so that federal funds go directly to helping vulnerable people. Little is known about how administrative costs compare among programs, or about opportunities to better manage these costs. GAO looked at (1) how administrative costs are defined and what rules govern federal and state participation in funding these costs; (2) what is known about the amounts of administrative spending and how they have changed over time; and (3) what opportunities exist at the federal level to help states balance cost savings with program effectiveness and integrity. GAO's review included seven programs: Adoption Assistance, Child Care and Development Fund (CCDF), Child Support Enforcement (CSE), food stamps, Foster Care, Temporary Assistance for Needy Families (TANF), and Unemployment Insurance (UI). To address the questions, GAO reviewed laws, analyzed spending data, and visited five states."

A letter report issued by the Government Accountability Office with an abstract that begins "The General Services Administration's (GSA) 218 high-value leases GAO reviewed represented only about 3 percent of the total number of GSA leases, yet made up about one-third of its leased portfolio in terms of cost and size. GSA has reduced the costs of its high-value leases in line with the administration's goal to reduce real property costs. GSA's efforts include helping agencies improve space utilization. However, for leases nearing expiration, GSA and tenant agencies have faced challenges in funding space renovations and moving costs. This lack of funds has contributed to delays and some cases in which GSA continues to occupy space after the lease expires."

A letter report issued by the General Accounting Office with an abstract that begins "The Centers for Medicare & Medicaid Services (CMS) recently implemented a Medicare ambulance fee schedule in which providers are paid a base payment per trip plus a mileage payment. An adjustment is made to the mileage rate for rural trips to account for higher costs. CMS has stated that this rural adjustment may not sufficiently target providers serving sparsely populated rural areas. The Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (BIPA) directed GAO to examine rural ambulance costs. GAO identified factors that affect ambulance costs per trip, examined how these factors varied across geographic areas, and analyzed whether Medicare payments account for geographic cost differences. GAO used survey data on ambulance providers and Medicare claims data."

A letter report issued by the Government Accountability Office with an abstract that begins "The Klamath River Basin Fishery Resources Restoration Act (Act), passed in October 1986, required the Secretary of the Interior to establish and restore a conservation area in that river basin, created a management council and a task force to assist and advise the Secretary, and authorized $21 million until September 30, 2006. The restoration program reports that it had been appropriated over $17 million by September 2005. In anticipation of the authorization's expiration, GAO was asked to provide information for fiscal years 2000 through 2004, the most recent 5-year period for which complete information is available, about (1) funding for the program; (2) expenditures by the program for restoration projects, travel expenses, administrative expenses, overhead, and technical support; (3) expenditures by the management council and the task force; and (4) whether the Secretary complied with certain requirements of the Act. GAO obtained funding and expenditure information from FWS but did not audit that financial information."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has designated the Department of Defense's (DOD) management of support infrastructure as a high risk area, in part because of challenges in reducing excess infrastructure. Operating and maintaining excess facilities consumes resources that could be eliminated from DOD's budget or used for other purposes. In response to direction in House Report 111-491, GAO reviewed DOD's (1) progress toward meeting demolition program targets for fiscal years 2008 through 2013; (2) facility utilization information--a source for identifying additional excess facilities; and (3) plans for managing and disposing of excess facilities after fiscal year 2013. GAO analyzed information on excess facilities, completed demolitions, and underutilized facilities in DOD's real property inventory database; reviewed DOD's plans for demolition after the on-going program ends; and conducted site visits to selected military installations."

A letter report issued by the General Accounting Office with an abstract that begins "The National Defense Authorization Act for Fiscal Year 2003 directed the Department of Defense (DOD) to develop an enterprise architecture and a transition plan that meets certain requirements. The act also directed DOD to have a process for controlling its system investments. As required by the act, GAO assessed DOD's actions to comply with the act's requirements and recently issued a report to congressional defense committees. This report provides further details of GAO's assessment results regarding (1) the extent to which DOD's actions complied with the requirements of the act and (2) DOD's plans for further development and implementation of its architecture."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Homeland Security (DHS) plans to establish a program to strengthen management of the pre-entry, entry, status, and exit of foreign nationals who travel to the United States. The goals of the program, known as the United States Visitor and Immigrant Status Indicator Technology (US-VISIT), are to facilitate legitimate trade and travel, enhance national security, and adhere to U.S. privacy laws and policies. By congressional mandate, DHS is to develop and submit for approval an expenditure plan for US-VISIT that satisfies certain conditions, including being reviewed by GAO. GAO was asked to determine, among other things, whether the plan satisfies these conditions and to provide observations about the plan and DHS's management of the program."
