Radionuclides in plankton from the South Pacific Basin
We have initiated an investigation of the utility of marine plankton as bioconcentrating samplers of low-level marine radioactivity in the southern hemisphere. A literature review has shown that both freshwater and marine plankton have trace element and radionuclide concentration factors (relative to water) of up to 10/sup 4/. We participated in Operations Deepfreeze 1981 and 1982, collecting a total of 48 plankton samples from the USCGC Glacier on its Antarctic cruises. Battelle Pacific Northwest Laboratories sampled air, water, rain, and fallout. We were able to measure concentrations in plankton of the naturally-occurring radionuclides /sup 7/Be, /sup 40/K, and the U and Th series, and we believe that we have detected low levels of /sup 144/Ce and /sup 95/Nb in seven samples ranging as far south as 68/sup 0/. Biological identification of the plankton suggests a possible correlation between radionuclide concentration and the protozoa content of the samples. 7 references, 5 figures.

Heat transfer research and power cycle transient modeling
Fine axial flutes enhance heat transfer in vertical shell-and-tube exchangers with water inside the tubes and ammonia evaporating or condensing in layer flow on the shell side. Single-tube experiments with R-11 and ammonia indicate local shell-side coefficients 3 to 5 times those for corresponding smooth tubes. Single-tube experiments with water indicate that at moderate velocities the tube-side coefficients are enhanced by a factor equal to the ratio of fluted-to-smooth surface areas while the fluid friction is similarly increased. The experimental data are transformed into mean individual coefficients for ammonia and water. Overall coefficients for a particular case are presented to illustrate the efficacy of enhancement by flutes on one or both sides of the heat transfer surface. Means are described for using emerging data to predict the static and dynamic behavior of the power cycle and the interactions of components throughout the complete power plant.

Evaluation of extraction chromatography for americium recovery
Extraction, or reverse-phase partition chromatography, as used mostly for analytical separations, employs an organic solvent extractant as a stationary phase on an inert support material. This technique, which has the advantage of utilizing the versatility of solvent extraction systems with the less expensive operation of ion exchange equipment, was evaluated for a process to recover low level concentrations of americium from acidic process waste streams at Rocky Flats. The bidentate organophosphorous extractant DHDECMP (dihexyl-N, N-diethylcarbamylmethylene phosphonate) was used as the stationary phase since it was shown to effectively scavenge americium from acidic waste streams without significantly extracting impurity ions. Over 30 support materials were evaluated for DHDECMP capacity and for their ability to retain the extractant. Of the supports tested, the Amberlite XAD macroreticular sorbents were found to have the highest DHDECMP capacity. Amberlite XAD-4 beads retained the extractant significantly better than the other supports evaluated. Thus, this solvent was tested for americium breakthrough capacity and compared to the theoretical capacity.

Calculation of Doppler Coefficient and Other Safety Parameters for a Large Fast Oxide Reactor
Several safety parameters are calculated for a large, fast, Na-cooled, oxide-fueled reactor. The Doppler coefficient is studied as regards its effect on the reactivity during a power excursion, and its dependence on the neutron spectrum, on the concentrations of U/sup 238/, Pu /sup 239/ , a nd Pu/sup 240/, on spatial temperature and power distributions, and on temperature. Other parameters studied include the Na temperature coefficient of reactivity, and the reactivity insertion caused by total Na loss; reactivity coefficients caused by thermal expansion of fuel and steel cladding; the excess operating reactivity; and the reactivity caused by a fuel slump. The effects of a Be reflector on neutron lifetimes are determined. The safety aspects are balanced against economic considerations. (T.F.H.)

IT Supply Chain: National Security-Related Agencies Need to Better Address Risks
A letter report issued by the Government Accountability Office with an abstract that begins "Reliance on a global supply chain introduces multiple risks to federal information systems. These risks include threats posed by actors—such as foreign intelligence services or counterfeiters—who may exploit vulnerabilities in the supply chain and thus compromise the confidentiality, integrity, or availability of an end system and the information it contains. This in turn can adversely affect an agency’s ability to effectively carry out its mission. Each of the key threats could create an unacceptable risk to federal agencies."

Nursing Homes: CMS Needs Milestones and Timelines to Ensure Goals for the Five-Star Quality Rating System Are Met
A letter report issued by the Government Accountability Office with an abstract that begins "CMS developed and implemented the Five-Star System largely during an 8-month period in 2008 with input from long-term care stakeholders, CMS’s Five-Star System contractor, and members of a technical expert panel—a panel composed of nine individuals that CMS identified as experts in long-term care research. CMS made numerous methodological decisions during the development of the Five-Star System, including three key methodological decisions. GAO defines key methodological decisions as those that at least six technical expert panel members—of the nine that GAO contacted—recalled as eliciting the most intense review and discussion during the development of the Five-Star System. One key methodological decision was how to combine the component ratings to create an overall rating. The other two key methodological decisions pertained to how to create ratings that account for variation in the type of care provided across nursing homes."

Department of Defense: Further Actions Needed to Establish and Implement a Framework for Successful Financial and Business Management Transformation
Testimony issued by the General Accounting Office with an abstract that begins "In March 2002, GAO testified on the Department of Defense's (DOD) financial management problems and key elements necessary for successful reform. Although the underlying conditions remain fundamentally unchanged, within the past 2 years DOD has begun a number of initiatives intended to address previously reported problems and transform its business operations. The Subcommittee on Readiness and Management Support, Senate Committee on Armed Services, asked GAO to provide a current status report on DOD's progress to date and suggestions for improvement. Specifically, GAO was asked to provide (1) an overview of the impact of financial and related business weaknesses on DOD operations, (2) the underlying causes of DOD business transformation challenges, and (3) the status of DOD reform efforts. In addition, GAO reiterates the key elements to successful reform: (1) an integrated business transformation strategy, (2) sustained leadership and resource control, (3) clear lines of responsibility and accountability, (4) results-oriented performance, (5) appropriate incentives and consequences, (6) an enterprise architecture to guide reform efforts, and (7) effective monitoring and oversight. GAO also offers two suggestions for legislative consideration which are intended to improve the likelihood of meaningful, broad-based financial …

Budget Process: Long-term Focus Is Critical
Testimony issued by the General Accounting Office with an abstract that begins "The structure of the budget process can help ensure that budget decision makers are presented with the information and choices for timely and informed decisionmaking. GAO's long-term budget simulations show that, absent substantive entitlement reform and/or dramatic changes in tax and spending policies, we will face large, escalating, and persistent deficits. A budget process incorporating new metrics and mechanisms that better signal the long-term commitments and promises made by the government will help concentrate decision makers' efforts on long-term sustainability."

DOE Nuclear Waste: Better Information Needed on Waste Storage at DOE Sites as a Result of Yucca Mountain Shutdown
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy's (DOE) Office of Environmental Management (EM) is responsible for storing and managing a total of about 13,000 metric tons of nuclear waste--spent nuclear fuel and high-level waste--at five DOE sites in Colorado, Idaho, New York, South Carolina, and Washington. Also, a joint DOE-Navy program stores spent nuclear fuel from warships at DOE's Idaho site. DOE and the Navy intended to permanently dispose of this nuclear waste at a repository planned for Yucca Mountain in Nevada. However, that plan is now in question because of actions taken to terminate the site. This report assesses (1) agreements DOE and the Navy have with states at the five sites and the effects a termination of the Yucca Mountain repository would have on their ability to fulfill these agreements; (2) the effects a termination would have on DOE's and the Navy's operations and costs for storing the waste; and (3) DOE's and the Navy's plans to mitigate these potential effects. GAO reviewed state agreements and DOE plans, visited waste facilities, and interviewed federal and state officials."

End-Stage Renal Disease: CMS Should Assess Adequacy of Payment When Certain Oral Drugs Are Included and Ensure Availability of Quality Monitoring Data
A letter report issued by the Government Accountability Office with an abstract that begins "For most individuals with end-stage renal disease (ESRD), Medicare purchases a bundle of dialysis-related services using a single payment. In 2014, the Centers for Medicare & Medicaid Services (CMS) plans to include in this bundled payment "oral-only" ESRD drugs used to treat mineral and bone disorder. Currently, Medicare generally pays for these drugs only if the beneficiary has Part D prescription drug coverage. This report (1) describes the rationales for including oral-only ESRD drugs in the bundled payment, (2) examines dialysis organizations' recent experience providing oral-only ESRD drugs and their future ability to provide these drugs, (3) examines the data sources that CMS could use to account for oral-only ESRD drugs in the bundled payment, and (4) examines CMS's ability to monitor treatment of mineral and bone disorder. GAO interviewed CMS officials, experts in mineral and bone disorder, and representatives of 4 large and 16 small dialysis organizations. GAO also reviewed ESRD payment regulations, related reports, clinical guidelines, and state pharmacy licensure requirements in 10 selected states."

Correspondence issued by the Government Accountability Office with an abstract that begins "DISH is cooperating with the Special Master’s examination, which consists of examining DISH’s compliance with the royalty payment and household eligibility requirements of the license under Section 119. Since beginning his examination, the Special Master has been holding regular meetings with representatives of DISH and NAB, which represents the four major networks and their affiliates. The Special Master requested, and DISH provided, information on DISH’s royalty calculations and payments to the Copyright Office. The Special Master told us that he is satisfied with the information provided by DISH to date and is currently in the process of reviewing the methodology DISH used for its royalty payments. To determine whether any problems exist with DISH’s services to eligible subscribers, and whether a more detailed examination of DISH’s records may be needed, DISH and NAB are collaborating on a survey of all major network-affiliated television broadcast stations nationwide. According to the parties, the survey is to be distributed twice: once in February 2012 and again in May 2012, to ensure that affiliated stations are not having issues with DISH’s services. The Special Master has been kept apprised of the development …

Veterans Health Care: VA's Medical Support Role in Emergency Preparedness
Correspondence issued by the Government Accountability Office with an abstract that begins "Since the terrorist attacks on September 11, 2001, the Department of Veterans Affairs (VA) has increased its efforts to plan for and respond to national emergencies, including acts of terrorism and natural disasters. Additionally, in August 2004, the Federal Bureau of Investigation and the Department of Homeland Security announced that military and VA medical facilities were potential terrorist targets. In light of military casualties from conflicts in Afghanistan and Iraq and continued threats of terrorist incidents, Congress asked us to review VA's medical support role in emergency preparedness. Specifically, we agreed to provide information on the following questions: (1) What is VA's role in providing medical support within the U.S. to military personnel in wartime and during national emergencies? (2) What actions has VA taken to improve its internal emergency preparedness to ensure that it is ready to maintain continuity of operations and provision of medical services to veterans? (3) What is VA's role in participating in emergency medical response measures with other federal, state, and local agencies?"

District of Columbia: National Museum of American Music
Correspondence issued by the General Accounting Office with an abstract that begins "GAO reviewed the non-profit and non-partisan Federal City Council's (FCC) proposal to use the current site of the Washington Convention Center for the National Museum of American Music (NMAM). The FCC proposal which is now in the conceptual stage anticipates that NMAM will be located at the existing Convention Center site and that it will be part of a major mixed-use complex that includes retail, entertainment, and performance venues. The total estimated cost for FCC's mixed-use proposal is $1.1 billion, with $172.5 million attributed to the music museum. The proposal estimates that the District would receive annual land rent of $13 million, equivalent to a seven-percent return on the estimated land value of $183 million. FCC spent $300,000 in federal appropriations on the project management services provided by the Smithsonian Institution. The District of Columbia has not yet considered any proposals for the use of the Convention Center site. The Mayor has established a task force to study the possible uses for the site, and it is developing a process to both solicit and evaluate independently generated proposals for the site."

Public Health and Hospital Emergency Preparedness Programs: Evolution of Performance Measurement Systems to Measure Progress
Correspondence issued by the Government Accountability Office with an abstract that begins "The September 11, 2001, terrorist attacks, the anthrax incidents during the fall of 2001, Hurricane Katrina, and concerns about the possibility of an influenza pandemic have raised public awareness and concerns about the nation's public health and medical systems' ability to respond to bioterrorist events and other public health emergencies. From 2002 to 2006, the Congress appropriated about $6.1 billion to the Department of Health and Human Services (HHS) to support activities to strengthen state and local governments' emergency preparedness capabilities under the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (Preparedness and Response Act). HHS has distributed funds annually to 62 recipients, including all 50 states and 4 large municipalities, through cooperative agreements under two programs--the Centers for Disease Control and Prevention's (CDC) Public Health Emergency Preparedness Program, and the Health Resources and Services Administration's (HRSA) National Bioterrorism Hospital Preparedness Program. The common goal of CDC's and HRSA's preparedness programs is to improve state and local preparedness to respond to bioterrorism and other large-scale public health emergencies, such as natural disasters or outbreaks of infectious disease. Annually, both CDC and HRSA develop and issue …
