Ab Initio Studies of Coke Formation on Ni Catalysts During Methane Reforming

Description: The atomic-scale processes that control the formation of carbon deposits on Ni catalysts in reforming applications are poorly understood. Ab initio Density Functional Theory calculations have been used to examine several key elementary steps in the complex network of chemical reactions that precedes carbon formation on practical catalysts. Attention has been focused on the disproportionation of CO. A comparative study of this reaction on flat and stepped crystal planes of Ni has provided the fi… more

Acceleration Measurements During Landings of a 1/5.5-Size Dynamic Model of the Columbia XJL-1 Amphibian in Smooth Water and in Waves: Langley Tank Model 208M, TED No. NACA 2336

Description: A 1/5.5-size powered dynamic model of the Columbia XJL-1 amphibian was landed in Langley tank no. 1 in smooth water and in oncoming waves of heights from 2.1 feet to 6.4 feet (full-size) and lengths from 50 feet to 264 feet (full-size). The motions and the vertical accelerations of the model were continuously recorded. The greatest vertical acceleration measured during the smooth-water landings was 3.1g.

Actinide Measurements by Accelerator Mass Spectrometry at Lawrence Livermore National Laboratory

Description: We report on the development of an accelerator mass spectrometry (AMS) system for the measurement of actinides at Lawrence Livermore National Laboratory. This AMS system is centered on a recently completed heavy isotope beam line that was designed particularly for high sensitivity, robust, high-throughput measurements of actinide concentrations and isotopic ratios. A fast isotope switching capability has been incorporated in the system, allowing flexibility in isotope selection and for the quas… more

Addressing Key Science and Technology Issues for IFE Chambers, Target Fabrication and Target Injection

Description: Significant progress has been made in addressing critical issues for high repetition rate chambers, target fabrication and injection for inertial fusion energy (IFE) for both heavy ion and laser drivers. Research is being conducted in a coordinated manner by national laboratories, universities and industry. This paper provides an overview of U.S. research activities and discusses how interface considerations (such as beam propagation and target survival during injection) impact design choices.

Advanced Reactors Transition program fiscal year 1998 multi-year work plan

Description: The mission of the Advanced Reactors Transition program is two-fold. First, the program is to maintain the Fast Flux Test Facility (FFTF) and the Fuels and Materials Examination Facility (FMEF) in Standby to support a possible future role in the tritium production strategy. Secondly, the program is to continue deactivation activities which do not conflict with the Standby directive. On-going deactivation activities include the processing of non-usable, irradiated, FFTF components for storage or… more

Aging Studies of 2nd Generation BaBar RPCs

Description: The BaBar detector, operating at the PEPII B factory of the Stanford Linear Accelerator Center (SLAC), installed over 200 2nd generation Resistive Plate Chambers (RPCs) in 2002. The streamer rates produced by backgrounds and signals from normal BaBar running vary considerably (0.1- >20 Hz/cm2) depending on the layer and position of the chambers, thus providing a broad spectrum test of RPC performance and aging. The lowest rate chambers have performed very well with stable efficiencies averag… more

ALT-GTS-Stem Fabrication

Description: In 2007, a study investigated options to manufacture stems utilizing methods that would replace crush form grinding while maintaining or improving quality at a comparative cost. Crush form grinding is a special process used at the Kansas City Plant to finish stem sections of reservoir products. However, crush form grinding is a complex process with many variables affecting the final product. This study identified two potential methods that can be applied to stems. Profile grinding was investiga… more

Analysis of Induced Gas Releases During Retrieval of Hanford Double-Shell Tank Waste

Description: Radioactive waste is scheduled to be retrieved from Hanford double-shell tanks AN-103, AN-104, AN-105, and AW-101 to the vitrification plant beginning about 2009. Retrieval may involve decanting the supernatant liquid and/or mixing the waste with jet pumps. In these four tanks, which contain relatively large volumes of retained gas, both of these operations are expected to induce buoyant displacement gas releases that can potentially raise the tank headspace hydrogen concentration to very near … more

Application of Prompt Gamma-Ray Analysis to Identify Electrorefining Salt-Bearing Plutonium Oxide at the Plutonium Finishing Plant

Description: Prompt gamma-ray analysis is being implemented at the Plutonium Finishing Plant (PFP) to screen impure plutonium oxide inventory items, received in the mid-1980s from the Rocky Flats Plant, for the presence of sodium chloride and potassium chloride salts from the electrorefining process. A large fraction of these items are suspected to contain electrorefining salts. Because the salts evaporate at the=950C stabilization temperature mandated for long-term storage under the U.S. Department of Ener… more

Armenia, Azerbaijan, and Georgia: Political Developments and Implications for U.S. Interests

Description: The United States recognized the independence of all the former Soviet republics by the end of 1991, including the South Caucasus states of Armenia, Azerbaijan, and Georgia. The United States has fostered these states' ties with the West in part to end the dependence of these states on Russia for trade, security, and other relations. The FREEDOM Support Act of 1992 provides authorization for assistance to the Eurasian states for humanitarian needs, democratization, and other purposes. In the af… more
