The 75As(n,2n) Cross Sections into the 74As Isomer and Ground State

Description: The {sup 75}As(n, 2n) cross section for the population of the T{sub 1/2} = 26.8-ns isomer at E{sub x} = 259.3 keV in {sup 74}As has been measured as a function of incident neutron energy, from threshold to E{sub n} = 20 MeV. The cross section was measured using the GEANIE spectrometer at LANSCE/WNR. For convenience, the {sup 75}As(n, 2n) population cross section for the {sup 74}As ground state has been deduced as the difference between the previously-known (n, 2n) reaction cross section and the… more

Application of Inorganic Membrane Technology to Hydrogen-hydrocarbon Separations

Description: Separation efficiency for hydrogen/light hydrocarbon mixtures was examined for three inorganic membranes. Five binary gas mixtures were used in this study: H{sub 2}/CH{sub 4} , H{sub 2}/C{sub 2}H{sub 6}, H{sub 2}/C{sub 3}H{sub 8}, He/CO{sub 2}, and He/Ar. The membranes examined were produced during a development program at the Inorganic Membrane Technology Laboratory in Oak Ridge and provided to us for this testing. One membrane was a (relatively) large-pore-diameter Knudsen membrane, and the o… more

ASSESSMENT OF HYDROCARBON SEEPAGE DETECTION METHODS ON THE FORT PECK RESERVATION, NORTHEAST MONTANA

Description: Surface exploration techniques have been employed in separate study areas on the Fort Peck Reservation in northeastern Montana. Anomalies associated with hydrocarbon seepage are documented in all three areas and a variety of surface exploration techniques can be compared. In a small area with established production, Head Gas and Thermal Desorption methods best match production; other methods also map depletion. In a moderate-size area that has prospects defined by 3D seismic data, Head Gas alon… more

A Cavity Ring-Down Spectroscopy Mercury Continuous Emission Monitor Progress Report

Description: Previous work on the detection of mercury using the cavity ring-down (CRD) technique has concentrated on the detection and characterization of the desired mercury transition. Interferent species present in flue gas emissions have been tested as well as a simulated flue gas stream. Additionally, work has been done on different mercury species such as the elemental and oxidized forms. The next phase of the effort deals with the actual sampling system. This sampling system will be responsible for … more

Child Support Enforcement: New Reforms and Potential Issues

Description: P.L. 104-193 (the 1996 welfare reform legislation) made major changes to the Child Support Enforcement (CSE) program. Some of the changes include requiring states to increase the percentage of fathers identified, establishing an integrated, automated network linking all states to information about the location and assets of parents, and requiring states to implement more enforcement techniques to obtain collections from debtor parents. Additional legislative changes were made in 1997, 1998, and… more

Crowtm Process Application for Sites Contaminated With Light Non-Aqueous Phase Liquids and Chlorinated Hydrocarbons

Description: Western Research Institute (WRI) has successfully applied the CROWTM (Contained Recovery of Oily Wastes) process at two former manufactured gas plants (MGPs), and a large wood treatment site. The three CROW process applications have all occurred at sites contaminated with coal tars or fuel oil and pentachlorophenol (PCP) mixtures, which are generally denser than water and are classified as dense non-aqueous phase liquids (DNAPLs). While these types of sites are abundant, there are also many sit… more

Defense Acquisitions: Matching Resources with Requirements Is Key to the Unmanned Combat Air Vehicle Program's Success

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) is developing a new unmanned combat air vehicle (UCAV) that can suppress enemy air defenses and conduct other air-to-ground attacks, particularly against heavily defended targets. Because it may perform these missions at a relatively low cost, the UCAV could be used to replace some of DOD's aging tactical aircraft fleet. A key to UCAV's success will lie in DOD's ability to match… more

The Effect of Applied Pressure During Feeding of Critical Cast Aluminum Alloy Components With Particular Reference to Fatigue Resistance

Description: the medium to long freezing range alloys of aluminum such as A356, A357, A206, 319 for example are known to exhibit dispersed porosity, which is recognized as a factor affecting ductility, fracture toughness, and fatigue resistance of light alloy castings. The local thermal environment, for example, temperature gradient and freezing from velocity, affect the mode of solidification which, along with alloy composition, heat treatment, oxide film occlusion, hydrogen content, and the extent to whic… more

High-Efficiency Steam Electrolyzer

Description: A hydrogen economy will require readily available and affordable hydrogen fuel. Current methods of hydrogen production do not fulfill these requirements. We are working on an electrolyzer system that can provide distributed hydrogen production while taking advantage of the nation's existing natural gas infrastructure. Electrolysis is a promising hydrogen production technology both because of its ability to produce pure hydrogen from water and because it does not require large, centralized plant… more

High Resolution Prediction of Gas Injection Process Performance for Heterogeneous Reservoirs Quarterly Report

Description: This report presents a detailed analysis of the development of miscibility during gas cycling in condensates and the formation of condensate banks at the leading edge of the displacement front. Dispersion-free, semi-analytical one-dimensional (1D) calculations are presented for enhanced condensate recovery by gas injection. The semi-analytical approach allows investigation of the possible formation of condensate banks (often at saturations that exceed the residual liquid saturation) and also al… more

HUMAN MACHINE COOPERATIVE TELEROBOTICS

Description: The remediation and deactivation and decommissioning (D&D) of nuclear waste storage tanks using telerobotics is one of the most challenging tasks faced in environmental cleanup. Since a number of tanks have reached the end of their design life and some of them have leaks, the unstructured, uncertain and radioactive environment makes the work inefficient and expensive. However, the execution time of teleoperation consumes ten to hundred times that of direct contact with an associated loss in… more
