Ability of Pilots to Control Simulated Short-Period Yawing Oscillations

Description: Report discussing an investigation into the ability of human pilots to control short-period yawing oscillations using a yaw simulating device. The ability to control the oscillations was determined to be a function of period, control effectiveness, and inherent damping. Pilot control effectiveness was found to improve with practice.

ADMINISTRATIVE AND ENGINEERING CONTROLS FOR THE OPERATION OF VENTILATION SYSTEMS FOR UNDERGROUND RADIOACTIVE WASTE STORAGE TANKS

Description: Liquid radioactive wastes from the Savannah River Site are stored in large underground carbon steel tanks. The majority of the waste is confined in double shell tanks, which have a primary shell, where the waste is stored, and a secondary shell, which creates an annular region between the two shells, that provides secondary containment and leak detection capabilities should leakage from the primary shell occur. Each of the DST is equipped with a purge ventilation system for the interior of the … more

ADVANCED HYBRID PARTICULATE COLLECTOR

Description: A new concept in particulate control, called an advanced hybrid particulate collector (AHPC), is being developed under funding from the US Department of Energy. The AHPC combines the best features of electrostatic precipitators (ESPs) and baghouses in a manner that has not been done before. The AHPC concept consists of a combination of fabric filtration and electrostatic precipitation in the same housing, providing major synergism between the two collection methods, both in the particulate coll… more

Advanced Mixing Models

Description: The process of recovering the waste in storage tanks at the Savannah River Site (SRS) typically requires mixing the contents of the tank with one to four dual-nozzle jet mixers located within the tank. The typical criteria to establish a mixed condition in a tank are based on the number of pumps in operation and the time duration of operation. To ensure that a mixed condition is achieved, operating times are set conservatively long. This approach results in high operational costs because of the… more

Aerodynamics of slender bodies at Mach number of 3.12 and Reynolds numbers from 2 x 10(exp 6) to 15 x 10(exp 6) 1: body of revolution with near-parabolic forebody and cylindrical afterbody

Description: An experimental investigation of the aerodynamic characteristics of a slender, square-based body of revolution was conducted at a Mach number of 3.12 for angles of attack from 0 degree to 10 degrees and for Reynolds numbers from 2 x 10(exp 6) to 15 x 10(exp 6). Boundary-layer measurements at zero angle of attack are compared with several compressible flow formulating for predicting boundary-layer characteristics. Comparison of experimental pressure and force values with theoretical values showe… more

Agriculture in the WTO Bali Ministerial Agreement

Description: At the World Trade Organization's (WTO's) Ninth Ministerial Conference in Bali, Indonesia, December 3-7, 2013, ministers adopted the so-called Bali Package--a series of decisions aimed at streamlining trade (referred to as trade facilitation), allowing developing countries more options for providing food security, boosting least-developed-country trade, and helping development more generally. This report focuses on those aspects of the Bali Package that deal with and are specific to agriculture… more

Air Quality: EPA’s 2006 Changes to the Particulate Matter (PM) Standard

Description: In order to better understand EPA’s actions, this report provides an analysis of the agency’s final 2006 revisions to the particulates NAAQS, and the estimated costs and benefits of the new standards and of a more stringent alternatives analyzed. The report concludes by highlighting concerns and issues raised regarding the revisions to the particulates standards, including those of the science advisory committee (Clean Air Scientific Advisory Committee, or CASAC), and actions in Congress.

Alternate immersion stress corrosion testing of 5083 aluminum

Description: The stress corrosion susceptibility of Type 5083 aluminum--magnesium alloy in plate form and press-formed shapes was determined in the short transverse direction. C-ring type specimens were exposed to alternate immersion in a sodium chloride solution. The test equipment and procedure, with several innovative features, are described in detail. Statistical test results are listed for seven thermomechanical conditions. A certain processing scheme was shown to yield a work-strengthened part that is… more

ALTERNATIVE MATERIALS TO PD MEMBRANES FOR HYDROGEN PURIFICATION

Description: Development of advanced hydrogen separation membranes in support of hydrogen production processes such as coal gasification and as front end gas purifiers for fuel cell based system is paramount to the successful implementation of a national hydrogen economy. Current generation metallic hydrogen separation membranes are based on Pd-alloys. Although the technology has proven successful, at issue is the high cost of palladium. Evaluation of non-noble metal based dense metallic separation membrane… more

Analysis of Data for Exports Regulated by the Department of Commerce

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "In light of the September 2001 terror attacks, we were asked to examine the Department of Commerce's Bureau of Industry and Security's (BIS) dual-use export control system. We reported our findings in a June 26, 2006, report, saying that BIS has not systematically evaluated the overall effectiveness and efficiency of the dual-use export control system. Specifically, we reported that BIS has not conducted… more

Anion Exchange Recovery of Plutonium From the Hanford 234-5 Building Button Line. Task I Oxalate Filtrate

Description: Resulte of a laboratory investigation undertaken to adapt the Pu anion exchange process to the direct recovery of the Pu lost to the Task I oxalate filtrate are reported. It was found that the Button Line Task I Filtrate can be recovered by HNO/sub 3/ anion exchange process, thus isolating the Button Line from any solvent extraction process. (J.R.D.)

Application of Covariance Data to Criticality Safety Data Validation

Description: The use of cross-section covariance data has long been a key part of traditional sensitivity and uncertainty analyses (S/U). This paper presents the application of S/U methodologies to the data validation tasks of a criticality safety computational study. The S/U methods presented are designed to provide a formal means of establishing the area (or range) of applicability for criticality safety data validation studies. The goal of this work is to develop parameters that can be used to formally d… more

Application of Neutron-Absorbing Structural-Amorphous Metal (SAM) Coatings for Spent Nuclear Fuel (SNF) Container to Enhance Criticality Safety Controls

Description: Spent nuclear fuel contains fissionable materials ({sup 235}U, {sup 239}Pu, {sup 241}Pu, etc.). Neutron multiplication and the potential for criticality are enhanced by the presence of a moderator during cask loading in water, water incursion in accidents conditions during spent fuel storage or transport. To prevent nuclear criticality in spent fuel storage, transportation, and during disposal, neutron-absorbing materials (or neutron poisons, such as borated stainless steel, Boral{trademark}, M… more

Behavior of Intruder Based States in Light Bi and Tl Isotopes: The Study of <sup>187</sup>Bi Alpha Decay

Description: The excitation energies of the single-particle normal and intruder levels in both `83T1 and 187Bi were measured for the first time via the ct decay of 187Bi produced in the 97Mo(92Mo,pn) 187Bi reaction. The previously unobserved 187Bi ground state (kw) to 183T1 ground state (s1/2) a transition was identified establishing the 187Bi intruder state excitation energy to be 112(21) keV, 70 keV less than that of the same level in 189Bi.
