The purpose of this report is to provide a concise status update for value-added products (VAP) implemented by the Atmospheric Radiation Measurement (ARM) Climate Research Facility. The report is divided into the following sections: (1) new VAPs for which development has begun, (2) progress on existing VAPs, (3) future VAPs that have been recently approved, (4) other work that leads to a VAP, and (5) top requested VAPs from the archive.

The C-band scanning ARM precipitation radar (C-SAPR) is a scanning polarimetric Doppler radar transmitting simultaneously in both H and V polarizations. With a 350-kW magnetron transmitter, this puts 125 kW of transmitted power for each polarization. The receiver for the C-SAPR is a National Center for Atmospheric Research (NCAR) -developed Hi-Q system operating in a coherent-on-receive mode. The ARM Climate Research Facility operates two C-SAPRs; one of them is deployed near the Southern Great Plains (SGP) Central Facility near the triangular array of X-SAPRs, and the second C-SAPR is deployed at ARM’s Tropical Western Pacific (TWP) site on Manus Island in Papua New Guinea.

The Low Activity Waste (LAW) tanks that are scheduled to provide the Hanford Tank Waste Treatment and Immobilization Plant (WTP) with waste feeds contain significant amounts of sulfate. The sulfate content in the LAW feeds is sufficiently high that a separate molten sulfate salt phase may form on top of the glass melt during the vitrification process unless suitable glass formulations are employed and sulfate levels are controlled. Since the formation of the salt phase is undesirable from many perspectives, mitigation approaches had to be developed. Considerable progress has been made and reported by the Vitreous State Laboratory (VSL) in enhancing sulfate incorporation into LAW glass melts and developing strategies to manage and mitigate the risks associated with high-sulfate feeds.

The project "Analyzing and visualizing next generation climate data" adds block-structured (mosaic) grid support, parallel processing, and 2D/3D curvilinear interpolation to the open-source UV-CDAT climate data analysis tool. Block structured grid support complies to the Gridspec extension submitted to the Climate and Forecast metadata conventions. It contains two parts: aggregation of data spread over multiple mosaic tiles (M-SPEC) and aggregation of temporal data stored in different files (F-SPEC). Together, M-SPEC and F-SPEC allow users to interact with data stored in multiple files as if the data were in a single file. For computational expensive tasks, a flexible, multi-dimensional, multi-type distributed array class allows users to process data in parallel using remote memory access. Both nodal and cell based interpolation is supported; users can choose between different interpolation libraries including ESMF and LibCF depending on the their particular needs.

Plans for the treatment of high level waste (HL W) at the Hanford Tank Waste Treatment and Immobilization Plant (WTP) are based upon the inventory of the tank wastes, the anticipated performance of the pretreatment processes, and current understanding of the capability of the borosilicate glass waste form [I]. The WTP HLW melter design, unlike earlier DOE melter designs, incorporates an active glass bubbler system. The bubblers create active glass pool convection and thereby improve heat and mass transfer and increase glass melting rates. The WTP HLW melter has a glass surface area of 3.75 m{sup 2} and depth of ~ 1.1 m. The two melters in the HLW facility together are designed to produce up to 7.5 MT of glass per day at 100% availability. Further increases in HL W waste processing rates can potentially be achieved by increasing the melter operating temperature above 1150�C and by increasing the waste loading in the glass product. Increasing the waste loading also has the added benefit of decreasing the number of canisters for storage.

Report that reviews the major facets of U.S.-India security relations with a focus on military-to-military contacts, counterterrorism and intelligence cooperation, and defense trade. It also discusses some of the many obstacles to deeper cooperation in each of these areas.

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Army Corps of Engineers (Corps) and the Department of Transportation (DOT) use a variety of programs to maintain and improve Marine Transportation System (MTS) infrastructure. The Corps is the lead federal agency responsible for maintaining and improving navigable waterways. Corps data show that obligations for navigable waterways have decreased from over $3 billion in fiscal year 2009 to about $1.8 billion in fiscal year 2011. Most annual DOT funding is provided to states through formulas, and states determine which projects to fund. For example, in fiscal year 2011, the Surface Transportation Program provided $9.5 billion to states for a variety of transportation projects, which may have included port improvements. However, because DOT does not specifically track formula funding used to maintain or improve ports or port connectors, officials were unable to provide GAO the extent to which these funds were used for port improvements, although the officials stated that the number of port-specific projects was likely small. Several DOT grant and credit programs can also provide specific funding to ports, though ports are primarily responsible for maintaining and improving infrastructure on port property."

A letter report issued by the Government Accountability Office with an abstract that begins "The Medicaid Integrity Group's (MIG) hiring of separate review and audit contractors for its National Medicaid Audit Program (NMAP) was inefficient and led to duplication because key functions were performed by both entities. Review contractors analyze state claims data to identify aberrant claims or billing anomalies while audit contractors conduct postpayment audits to determine if payments to providers were improper. Because both types of contractors had to assess whether payments were improper under state Medicaid policies, having separate contractors doubled states' burden in ensuring that state policies were being correctly applied. Also, poor coordination and communication between the two types of contractors resulted in duplicative data analysis. In turn, these inefficiencies added to the length of audits, which on average took almost 23 months to complete. By contrast, the average duration of six audits using a more collaborative and coordinated approach was 16 months, and the amount of identified overpayments increased significantly."

A letter report issued by the Government Accountability Office with an abstract that begins "Use of prepayment edits saved Medicare at least $1.76 billion in fiscal year 2010, but GAO found that savings could have been greater had prepayment edits been more widely used. GAO illustrated this point using analysis of a limited number of national policies and local coverage determinations (LCD), which are established by each Medicare administrative contractor (MAC) to specify coverage rules in its jurisdiction. GAO identified $14.7 million in payments in fiscal year 2010 that appeared to be inconsistent with four national policies and therefore improper. These payments could have been prevented through automated prepayment edits. GAO also found more than $100 million in payments that were inconsistent with three selected LCDs and that could have been identified using automated edits."

Tokamak start-up on present-day devices usually relies on inductively induced voltage from a central solenoid. In some cases inductive startup is assisted with auxiliary power from electron cyclotron radio frequency heating. ITER, the National Spherical Torus eXperiment Upgrade and JT60, now under construction, will make use of the understanding gained from present-day devices to ensure successful start-up. Design of a spherical tokamak (ST) with DT capability for nuclear component testing would require an alternative to a central solenoid because the small central column in an ST has insufficient space to provide shielding for the insulators in the solenoid. Alternative start-up techniques such as induction using outer poloidal field coils, electron Bernstein wave start-up, coaxial helicity injection and point source helicity injection have been used with success, but require demonstration of scaling to higher plasma current.
