Local Effects of Biased Electrodes in the Divertor of NSTX (open access)

Local Effects of Biased Electrodes in the Divertor of NSTX

The goal of this paper is to characterize the effects of small non-axisymmetric divertor plate electrodes on the local scrape-off layer plasma. Four small rectangular electrodes were installed into the outer divertor plates of NSTX. When the electrodes were located near the outer divertor strike point and biased positively, there was an increase in the nearby probe currents and probe potentials and an increase in the LiI light emission at the large major radius end of these electrodes. When an electrode located farther outward from the outer divertor strike point was biased positively, there was sometimes a significant decrease in the LiI light emission at the small major radius end of this electrode, but there were no clear effects on the nearby probes. No non-local effects were observed with the biasing of these electrodes.

9978 AND 9975 TYPE B PACKAGING INTERNAL DATA COLLECTION FEASIBILITY TESTING (open access)

9978 AND 9975 TYPE B PACKAGING INTERNAL DATA COLLECTION FEASIBILITY TESTING

The objective of this report is to document the findings from a series of proof-of-concept tests performed by Savannah River National Laboratory (SRNL) R and D Engineering, for the DOE Packaging Certification Program to determine if a viable radio link could be established from within the stainless steel confines of several drum-style DOE certified Type B radioactive materials packagings. Two in-hand, off-the-shelf radio systems were tested. The first system was a Wi-Fi Librestream Onsight{trademark} camera with a Fortress ES820 Access Point and the second was the On-Ramp Wireless Ultra-Link Processing{trademark} (ULP) radio system. These radio systems were tested within the Model 9975 and 9978 Type B packagings at the SRNL. This report documents the test methods and results. A path forward will also be recommended.

U.S. Nuclear Cooperation with India: Issues for Congress

India, which has not signed the Nuclear Nonproliferation Treaty and does not have International Atomic Energy Agency safeguards on all of its nuclear material, exploded a “peaceful” nuclear device in 1974, convincing the world of the need for greater restrictions on nuclear trade. The United States created the Nuclear Suppliers Group (NSG) as a direct response to India's test, halted nuclear exports to India a few years later, and worked to convince other states to do the same. India tested nuclear weapons again in 1998. This report looks at how the relationship between the Bush Administration and the Obama Administration with India in regards to nuclear power.

GLYCOLIC-NITRIC ACID FLOWSHEET DEMONSTRATION OF THE DWPF CHEMICAL PROCESSING CELL WITH MATRIX SIMULANTS AND SUPERNATE (open access)

GLYCOLIC-NITRIC ACID FLOWSHEET DEMONSTRATION OF THE DWPF CHEMICAL PROCESSING CELL WITH MATRIX SIMULANTS AND SUPERNATE

Savannah River Remediation (SRR) is evaluating changes to its current DWPF flowsheet to improve processing cycle times. This will enable the facility to support higher canister production while maximizing waste loading. Higher throughput is needed in the CPC since the installation of the bubblers into the melter has increased melt rate. Due to the significant maintenance required for the DWPF gas chromatographs (GC) and the potential for production of flammable quantities of hydrogen, reducing or eliminating the amount of formic acid used in the CPC is being developed. Earlier work at Savannah River National Laboratory has shown that replacing formic acid with an 80:20 molar blend of glycolic and formic acids has the potential to remove mercury in the SRAT without any significant catalytic hydrogen generation. This report summarizes the research completed to determine the feasibility of processing without formic acid. In earlier development of the glycolic-formic acid flowsheet, one run (GF8) was completed without formic acid. It is of particular interest that mercury was successfully removed in GF8, no formic acid at 125% stoichiometry. Glycolic acid did not show the ability to reduce mercury to elemental mercury in initial screening studies, which is why previous testing focused on using …

Insourcing Functions Performed by Federal Contractors: An Overview of the Legal Issues

Recent Congresses and the Obama Administration have taken numerous actions to promote "insourcing," or the use of government personnel to perform functions that contractors have performed on behalf of federal agencies. Members of the 112th Congress have introduced several measures which seek to ensure that certain contractors have standing to challenge insourcing determinations; would provide for additional review of insourcing determinations that affect small businesses; or could otherwise constrain insourcing initiatives.

Troubled Asset Relief Program: Government's Exposure to AIG Lessens as Equity Investments Are Sold (open access)

Troubled Asset Relief Program: Government's Exposure to AIG Lessens as Equity Investments Are Sold

A letter report issued by the Government Accountability Office with an abstract that begins "Since GAO’s last report in July 2011, more of the assistance provided by the Department of the Treasury (Treasury) and the Board of Governors of the Federal Reserve System (Federal Reserve) to benefit American International Group, Inc. (AIG) has been repaid. As of March 22, 2012, the remaining assistance to AIG was $46.3 billion, including unpaid dividends and accrued interest. This amount includes Treasury’s $35.9 billion investment in AIG common stock and a balance of $8.3 billion owed by Maiden Lane III to the Federal Reserve Bank of New York (FRBNY). This remaining assistance was down from $92.5 billion in March 2011 and $154.7 billion in December 2010. Several indicators show that as of March 2012, the government’s remaining outstanding assistance to AIG has continued to be reduced, mostly because of repayments on the FRBNY loan to Maiden Lane II; repayment of AIA Aurora, LLC, a special purpose vehicle; and sales of Treasury’s common stock in AIG. The government’s outstanding assistance to AIG is largely composed of Treasury’s common stock in AIG. Treasury’s sales of AIG stock in May 2011 and March 2012 have yielded total …
