Navy Acquisitions: Improved Littoral War-Fighting Capabilities Needed

Description: A letter report issued by the General Accounting Office with an abstract that begins "According to the Navy, the primary purpose of forward-deployed naval forces is to project power from the sea to influence events ashore. To be successful, naval forces must be able to gain access to, and operate in the coastal areas of potential adversaries. Consequently, they must be able to detect and neutralize enemy sea mines and other antiship weapons. Finally, they must be able to launch and support offe… more

Financial Management: Improvements in Air Force Fund Balance With Treasury Reconciliation Process

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) has had longstanding problems in reconciling the transaction activity in its Fund Balance with Treasury accounts. These reconciliation problems hamper DOD's ability to prepare auditable financial statements and have prompted GAO to place DOD financial management on its list of government activities at high risk for waste, fraud, abuse, and mismanagement. In August 1998, DOD deve… more

Effects of pressure and saturation on seismic velocities and impedance measurements

Description: Two synthetic data sets were examined to study the possible methods for distinguishing the effects of changes in saturation, and changes in pore pressure, on seismic velocity and impedance measurements. The results show that the results obtained previously on the dependence of laboratory velocity data on changes in saturation carry over without change to the data in these data sets. The assumption in this case is that the only data available are the seismic velocities. This situation can arise … more

Comparison of Machining with Long-Pulse Green and Ultrashort Pulse Lasers

Description: (1) LLNL measured the material removal rate from stainless steel, silicon carbide, rhenium, N5, hastalloy X, and titanium as a function of pulse fluence at a wavelength of 810 nm for pulse durations of 150 fs, 1.5 ps, 20 ps, and 500 ps. The spot size of the beam used was 150 microns in diameter and the nominal material thickness was 1-2 mm. These experiments were performed on the existing 1 kHz laser system. Holes of different penetration depths were obtained to ascertain change in removal rate… more

Debuncher Momentum Cooling Systems Signal to Noise Measurements

Description: The Debuncher Momentum cooling systems were carefully measured for signal to noise. It was observed that cooling performance was not optimum. Closer inspection shows that the installed front-end bandpass filters are wider than the pickup response. (The original filters were specified to be wider so that none of the available bandwidth would be clipped.) The end result is excess noise is amplified and passed onto the kickers unimpeded, hence, reducing the achievable system gain. From this data, … more

Development of Numerical Grids for UZ Flow and Transport Modeling

Description: This Analysis/Model Report (AMR) describes the methods used to develop numerical grids of the unsaturated hydrogeologic system beneath Yucca Mountain. Numerical grid generation is an integral part of the development of a complex, three-dimensional (3-D) model, such as the Unsaturated-Zone Flow and Transport Model (UZ Model) of Yucca Mountain. The resulting numerical grids, developed using current geologic, hydrogeologic, and mineralogic data, provide the necessary framework to: (1) develop cali… more

THREE DIMENSIONAL INTEGRATED CHARACTERIZATION AND ARCHIVING SYSTEM (3D-ICAS)

Description: The overall objective of this project is to develop an integrated system that remotely characterizes, maps, and archives measurement data of hazardous decontamination and decommissioning (D&D) areas. The system will generate a detailed 3-dimensional topography of the area as well as real-time quantitative measurements of volatile organics and radionuclides. The system will analyze substrate materials consisting of concrete, asbestos, and transite. The system will permanently archive the dat… more

Design of a System for the Nondestructive Assay of {sup 233}U in Waste Drums

Description: A system for the nondestructive assay of waste drums containing {sup 233}U has been installed in Bldg. 3019. This system employs two 3 x 3 in. NaI scintillation detectors, and standard counting techniques and analyses of the 2.6-MeV gamma radiation emitted by {sup 208}Tl. Thallium-208 is a product of the decay of {sup 232}U, which is usually present as an impurity in {sup 233}U. Results show that the system is capable of determining gram quantities of {sup 233}U in a 55-gal rotating drum. Stand… more

Factors Affecting the Hydrogen Embrittlement Resistance of Ni-Cr-Mn-Nb Welds

Description: Nickel based alloys are often welded with argon/hydrogen shielding gas mixtures to minimize oxidation and improve weld quality. However, shielding gas mixtures with {ge} 1% hydrogen additions can result in hydrogen concentrations greater than 5 wt. ppm in the weld metal and reduce ductility via hydrogen embrittlement. For the conditions investigated, the degree of hydrogen embrittlement is highly variable between 5 and 14 wt. ppm. investigation of hydrogen embrittlement of EN82H GTAW welds via … more

Saturated Zone Colloid-Facilitated Transport

Description: The purpose of the Saturated Zone Colloid-Facilitated Transport Analysis and Modeling Report (AMR), as outlined in its Work Direction and Planning Document (CRWMS M&O 1999a), is to provide retardation factors for colloids with irreversibly-attached radionuclides, such as plutonium, in the saturated zone (SZ) between their point of entrance from the unsaturated zone (UZ) and downgradient compliance points. Although it is not exclusive to any particular radionuclide release scenario, this AMR… more

Mechanisms of Stochastic Diffusion of Energetic Ions in Spherical Tori

Description: Stochastic diffusion of the energetic ions in spherical tori is considered. The following issues are addressed: (I) Goldston-White-Boozer diffusion in a rippled field; (ii) cyclotron-resonance-induced diffusion caused by the ripple; (iii) effects of non-conservation of the magnetic moment in an axisymmetric field. It is found that the stochastic diffusion in spherical tori with a weak magnetic field has a number of peculiarities in comparison with conventional tokamaks; in particular, it is cha… more

Confinement of Neutral Beam Ions in the National Spherical Torus Experiment

Description: The loss of neutral-beam ions to the wall has been measured in the National Spherical Torus Experiment (NSTX) by means of thermocouples, an infrared (IR) camera, and a Faraday cup probe. The losses tend to exhibit the expected dependences on plasma current, tangency radius of the injector, and plasma outer gap. However, the thermocouples and the Faraday cups indicate substantially different levels of loss and this difference has yet to be understood.

Estimation of Fracture Porosity in an Unsaturated Fractured Welded Tuff Using Gas Tracer Testing

Description: Kinematic fracture porosity is an important hydrologic transport parameter for predicting the potential of rapid contaminant migration through fractured rock. The transport velocity of a solute moving within a fracture network is inversely related to the fracture porosity. Since fracture porosity is often one or two orders of magnitude smaller than matrix porosity, and fracture permeability is often orders of magnitude greater than matrix permeability, solutes may travel significantly faster in… more

Results of The Analysis of The Blood Beryllium Lymphocyte Proliferation Test Data From The Oak Ridge Y-12 Study

Description: The potential hazards from exposure to beryllium or beryllium compounds in the workplace were first reported in the 1930s. The tritiated thymidine beryllium lymphocyte proliferation test (BeLPT) is an in vitro blood test that is widely used to screen beryllium exposed workers in the nuclear industry for sensitivity to beryllium. Newman [18] has discussed the clinical significance of the BeLPT and described a standard protocol that was developed in the late 1980s. Cell proliferation is measured … more
