A letter report issued by the Government Accountability Office with an abstract that begins "The performance of the National Aeronautics and Space Administration’s (NASA) portfolio of major projects has improved in the areas of cost and schedule growth since GAO’s first assessment in 2009. Average development cost growth and schedule delay for the current portfolio have decreased to about a third of their 2009 levels."

Testimony issued by the Government Accountability Office with an abstract that begins "The new F-35 acquisition baseline reflects positive restructuring actions taken by the Department of Defense (DOD) since 2010, including more time and funding for development and deferred procurement of more than 400 aircraft to future years. Overall, the program progressed on several fronts during 2012 to further improve the current outlook. The program achieved 7 of 10 key management objectives and made substantial progress on one other. Two objectives on aircraft deliveries and a corrective management plan were not met. The F-35 development test program substantially met expectations with some revisions to flight test plans and made considerable progress addressing key technical risks. Software management practices and some output measures improved, although deliveries to test continued to lag behind plans. Manufacturing and supply processes also improved--indicators such as factory throughput, labor efficiency, and quality measures were positive. While initial F-35 production overran target costs and delivered aircraft late, the latest data shows labor hours decreasing and deliveries accelerating."

A letter report issued by the Government Accountability Office with an abstract that begins "Over time, Congress has modified how Medicare reimburses certain hospitals under the inpatient prospective payment system (IPPS), which pays hospitals a flat fee per stay, set in advance, with different amounts for each type of condition. GAO identified numerous statutory provisions that individually increased Medicare payments to a subset of hospitals."

Testimony issued by the Government Accountability Office with an abstract that begins "The AMP process, which the judiciary has applied to about 67 percent of its courthouses, represents progress by the judiciary in aligning its capital-planning process with leading capital-planning practices, but the document the judiciary uses to request courthouse construction projects from Congress lacks transparency and key information. For example, the AMP process better aligns with leading practices for identifying real property needs by establishing a comprehensive, nationwide 328-factor analysis of every courthouse, whereas the previous process only assessed courthouses when requested by a local judicial district. However, the AMP process does not fully align with several leading practices due to, for example, its lack of linkage to the judiciary's strategic plan. Two courthouse projects illustrate how the AMP process has changed the way the judiciary evaluates its need for new courthouses. Specifically, two projects listed on a previous 5-year plan (covering fiscal years 2012 through 2016) were re-evaluated under AMP--San Jose, California, and Greenbelt, Maryland. Both had ranked among the top 15 most urgent projects nationwide under the previous capital-planning process, and as such, the judiciary prioritized them for new construction in 2010. However, after the judiciary evaluated …

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Internal Revenue Service (IRS), 12 of its 20 major information technology (IT) investments were within 10 percent of cost and schedule estimates or significantly below cost between October 2011 and October 2012. For the remaining 8 investments, 3 were reported as being significantly over cost and 5 were reported as being significantly behind schedule. Reported reasons for these significant variances include unplanned work activities, procurement delays, and additional costs associated with terminating an investment that was being replaced."

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past 5 years, the U.S. Postal Service (USPS) has taken several actions to restructure its retail network through reducing its workforce and its footprint while expanding retail alternatives. USPS officials estimated that it had saved about $800 million from reducing the number of work hours dedicated to retail operations. USPS also closed 631 of its post offices, but it did not have cost-savings estimates for these closures. Most of the facilities closed (500) were in response to a postmaster vacancy or the suspension of operations due to an expired lease or irreparable damage following a natural disaster. Fewer closures (131) have resulted from nationwide reviews that USPS initiated in 2009 and 2011. USPS has also restructured its retail network by expanding alternatives through self-service options as well as partnerships with other retailers."

Testimony issued by the Government Accountability Office with an abstract that begins "The National Defense Authorization Act for Fiscal Year 2011 mandated that GAO examine the costs and benefits of an increased Department of Defense (DOD) role to help secure the southwest land border. This mandate directed that GAO report on, among other things, the potential deployment of additional units, increased use of ground-based mobile surveillance systems, use of mobile patrols by military personnel, and an increased deployment of unmanned aerial systems and manned aircraft in national airspace. In September 2011, GAO reported that DOD estimated a total cost of about $1.35 billion for two separate border operations—Operation Jump Start and Operation Phalanx—conducted by National Guard forces in Title 32 status from June 2006 to July 2008 and from June 2010 through September 30, 2011, respectively. Further, DOD estimated that it has cost about $10 million each year since 1989 to use active duty Title 10 forces nationwide, through its Joint Task Force-North, in support of drug law enforcement agencies with some additional operational costs borne by the military services. Agency officials stated multiple benefits from DOD’s increased border role, such as assistance to the Department of Homeland Security (DHS) …

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Postal Service (USPS) continues to incur unsustainable operating deficits, has not made required payments of $11.1 billion to prefund retiree health benefits, and has reached its $15 billion borrowing limit. Thus far, USPS has been able to operate within these constraints, but now faces a critical shortage of liquidity that threatens its financial solvency and ability to finance needed capital investment. USPS had an almost 25 percent decline in total mail volume and net losses totaling $40 billion since fiscal year 2006. While USPS achieved about $15 billion in savings and reduced its workforce by about 168,000 over this period, its debt and unfunded benefit liabilities grew to $96 billion by the end of fiscal year 2012. USPS expects mail volume and revenue to continue decreasing as online bill communication and e-commerce expand."

In the wake of the explosion of the Deepwater Horizon offshore drilling rig in the Gulf of Mexico on April 20, 2010, federal agencies, state and local government agencies, and responsible parties faced an unprecedented challenge. An oil discharge continued for 87 days, resulting in the largest ever oil spill in U.S. waters.

This report documents the laboratory testing and analyses as directed under the test plan, LAB-PLN-11-00010, Evaluation of Technetium Ion Exchange Material against Hanford Double Shell Tank Supernate Simulate with Pertechnetate. Technetium (Tc-99) is a major fission product from nuclear reactors, and because it has few applications outside of scientific research, most of the technetium will ultimately be disposed of as nuclear waste. The radioactive decay of Tc-99 to ruthenium 99 (Ru-99) produces a low energy {beta}{sup -} particle (0.1 MeV max). However, due to its fairly long half-life (t{sub 1/2} = 2.13E05 years), Tc-99 is a major source of radiation in low-level waste (UCRL-JRNL-212334, Current Status of the Thermodynamic Data for Technetium and its Compounds and Aqueous Species). Technetium forms the soluble oxy anion, TcO{sub 4}{sup -} under aerobic conditions. This anion is very mobile in groundwater and poses a health risk (ANL, Radiological and Chemical Fact Sheets to Support Health Risk Analyses for Contaminated Areas). It has been demonstrated that Purolite{reg_sign} A530E is highly effective in removing TcO{sub 4}{sup -} from a water matrix (RPP-RPT-23199, The Removal of Technetium-99 from the Effluent Treatment Facility Basin 44 Waste Using Purolite A-530E, Reillex HPQ, and Sybron IONAC SR-7 Ion Exchange Resins). …

This Letter presents the rst numerical veri cation for the bounce-harmonic (BH) resonance phenomena of the neoclassical transport in a tokamak perturbed by non-axisymmetric magnetic elds. The BH resonances were predicted by analytic theories of neoclassical toroidal viscosity (NTV), as the parallel and perpendicular drift motions can be resonant and result in a great enhancement of the radial momentum transport. A new drift-kinetic #14;f guiding-center particle code, POCA, clearly veri ed that the perpendicular drift motions can reduce the transport by phase-mixing, but in the BH resonances the motions can form closed orbits and particles radially drift out fast. The POCA calculations on resulting NTV torque are largely consistent with analytic calculations, and show that the BH resonances can easily dominate the NTV torque when a plasma rotates in the perturbed tokamak and therefore is a critical physics for predicting the rotation and stability in ITER. __________________________________________________

Results from a free-surface MHD flow experiment are presented detailing the modi cation of vortices in the wake of a circular cylinder with its axis parallel to the applied magnetic fi eld. Experiments were performed with a Reynolds number near Re ~ 104 as the interaction parameter, N = |j x#2; B| / |ρ (υ ⋅ ∇), was increased through unity. By concurrently sampling the downstream fluid velocity at sixteen cross-stream locations in the wake, it was possible to extract an ensemble of azimuthal velocity profi les as a function of radius for vortices shed by the cylinder at varying strengths of magnetic field. Results indicate a signi cant change in vortex radius and rotation as N is increased. The lack of deviations from the vortex velocity pro file at high magnetic fi elds suggests the absence of small-scale turbulent features. By sampling the wake at three locations downstream in subsequent experiments, the decay of the vortices was examined and the effective viscosity was found to decrease as N-049±0.4. This reduction in effective viscosity is due to the modi cation of the small-scale eddies by the magnetic fi eld. The slope of the energy spectrum was observed to change from …

The Office of Waste Processing, within the Office of Technology Innovation and Development, funded the development of an enhanced Caustic-Side Solvent Extraction (CSSX) solvent for deployment at the Savannah River Site for removal of cesium from High Level Waste. This effort lead to the development of the Next Generation Solvent (NGS) with Tris (3,7-dimethyl octyl) guanidine (TiDG). The first deployment target for the NGS solvent is within the Modular CSSX Unit (MCU). Deployment of a new chemical within an existing facility requires verification that the new chemical components are compatible with the installed equipment. In the instance of a new organic solvent, the primary focus is on compatibility of the solvent with organic polymers used in the affected facility. This report provides the calculated data from exposing these polymers to the Next Generation Solvent. An assessment of the dimensional stability of polymers known to be used or present in the MCU, Defense Waste Processing Facility (DWPF), and Saltstone facilities that will be exposed to the NGS showed that TiDG could selectively affect the elastomers and some thermoplastics to varying extents, but the typical use of these polymers in a confined geometry will likely prevent the NGS from impacting component performance. …

With funds provided by the US DOE, Argonne National Laboratory subcontracted the design of batch and column studies to a Stanford University team with field experience at the ORNL IFRC, Oak Ridge, TN. The contribution of the Stanford group ended in 2011 due to budget reduction in ANL. Over the funded research period, the Stanford research team characterized ORNL IFRC groundwater and sediments and set up microcosm reactors and columns at ANL to ensure that experiments were relevant to field conditions at Oak Ridge. The results of microcosm testing demonstrated that U(VI) in sediments was reduced to U(IV) with the addition of ethanol. The reduced products were not uraninite but were instead U(IV) complexes associated with Fe. Fe(III) in solid phase was only partially reduced. The Stanford team communicated with the ANL team members through email and conference calls and face to face at the annual ERSP PI meeting and national meetings.
