Contract Types: An Overview of the Legal Requirements and Issues

Description: This report provides an overview of the various contract types (e.g., fixed-price, cost-reimbursement) used in federal procurement and the legal requirements and issues pertaining to each. Current congressional and public interest in contract types is, in part, an outgrowth of the reported increase in the use of cost-reimbursement contracts during the George W. Bush Administration and the Obama Administration's proposal to reduce by at least 10% the funds obligated by "high risk-contracting authorities," such as cost-reimbursement, time-and-materials, and labor-hour contracts, in FY2010.

Magnetic excitations in a random exchange system Fe{sub x}Mn{sub 1-x}TiO{sub 3}

Description: In order to examine the influence of exchange frustration on spin wave excitations, inelastic neutron scattering experiments have been performed on a random exchange system Fe{sub x}Mn{sub l-x}TiO{sub 3} with x = 0.00, 0.10, 0.25 and 0.33. For all three mixed systems, the magnetic excitation spectra consist of two components: a well-defined spin wave component and a broad damped component. The latter can be well fitted to a spectral weight function for a damped harmonic oscillator.

Development of Commercial Applications of a FAPY Alloy

Description: The Fe-16 at. (8.5 wt) % Al alloy, known as FAPY, has been identified as a superior material for heating element applications. However, while the 15-lb heats melted at the Oak Ridge National Laboratory (ORNL) could be processed into wire, the large heat melted at Hoskins Manufacturing Company (Hoskins) could not be processed under commercial processing conditions. The primary objective of the Cooperative Research and Development Agreement (CRADA) was to demonstrate that wire of the FAPY alloy could be produced under commercial conditions from air-induction-melted (AIM) heats. The specific aspects of this CRADA included: (1) Melting 15-lb heats by AIM or vacuum-induction melting (VIM) at ORNL. (2) Development of detailed processing steps including warm drawing and annealing temperature and time during cold-drawing steps. (3) Melting of 1400-lb heats at Hoskins by the Exo-Melt{trademark} process and their chemical analysis and microstructural characterization. (4) Development of tensile properties of sections of ingots from the large heats in the ascast, hot-worked, and hot- and cold-worked conditions. (5) Microstructural characterization of cast and wrought structures and the fractured specimens. (6) Successful demonstration of processing of AIM heats at Hoskins to heating element wire. The aspects of this CRADA listed above have demonstrated that the FAPY alloy of the desired composition can be commercially produced by AIM by the use of the Exo-Melt{trademark} process. Furthermore, it also demonstrated that the wire processing steps developed for 15-lb heats at ORNL can be successfully applied to the production of wire from the large AIM heats.

Analysis of Soil Remediation Requirements of Abandoned Centralized and Commercial Drilling

Description: During this reporting period our project focused on (1) review of case studies of remediation of centralized and commercial drilling fluid disposal (CCDD) sites in Texas, and (2) information transfer with preparation of a proceedings paper and a workshop/short course. Texas remediation of certain drilling-fluid disposal sites includes examples at CCDD sites as well as commercial oil reclamation sites and saltwater disposal sites that also disposed of drilling fluids in pits. Site investigations range from qualitative visual inspection and assessment to comprehensive hydrodynamic, chemical, and geophysical analyses of wastes and groundwater. A range of techniques has been used to evaluate waste material, soil, groundwater, and surface water for potential contamination with hydrocarbons, chemicals, saltwater, and naturally occurring radioactive materials (NORM). Most constituents of concern measured in these studies are below regulatory action levels and established guidelines. A proceedings paper summarizes results presented in this and previous semi-annual progress reports will be part of the Transactions of the Gulf Coast Association of Geological Societies (GCAGS). A technology transfer workshop also was prepared as part of that Annual Meeting of the GCAGS to be held in November 2002.

Effect of Canister Movement on Water Turbidity

Description: Requirements for evaluating the adherence characteristics of sludge on the fuel stored in the K East Basin and the effect of canister movement on basin water turbidity are documented in Briggs (1996). The results of the sludge adherence testing have been documented (Bergmann 1996). This report documents the results of the canister movement tests. The purpose of the canister movement tests was to characterize water turbidity under controlled canister movements (Briggs 1996). The tests were designed to evaluate methods for minimizing the plumes and controlling water turbidity during fuel movements leading to multi-canister overpack (MCO) loading. It was expected that the test data would provide qualitative visual information for use in the design of the fuel retrieval and water treatment systems. Video recordings of the tests were to be the only information collected.

Plasma-assisted catalytic reduction of NO<sub>x</sub>

Description: Many studies suggest that lean-NO<sub>x</sub> SCR proceeds via oxidation of NO to NO¬ by oxygen, followed by the reaction of the NO¬ with hydrocarbons. On catalysts that are not very effective in catalyzing the equilibration of NO+O¬ and NO¬, the rate of N¬ formation is substantially higher when the input NO<sub>x</sub> is NO¬ instead of NO. The apparent bifunctional mechanism in the SCR of NO<sub>x</sub> has prompted the use of mechanically mixed catalyst components, in which one component is used to accelerate the oxidation of NO to NO¬, and another component catalyzes the reaction between NO¬ and the hydrocarbon. Catalysts that previously were regarded as inactive for NO<sub>x</sub> reduction could therefore become efficient when mixed with an oxidation catalyst. Preconverting NO to NO¬ opens the opportunity for a wider range of SCR catalysts and perhaps improves the durability of these catalysts. This paper describes the use of a non-thermal plasma as an efficient means for selective partial oxidation of NO to NO¬. When combined with some types of SCR catalyst, the plasma can greatly enhance the NO<sub>x</sub> reduction and eliminate some of the deficiencies encountered in an entirely catalyst-based approach. efficiency for reduction of NO<sub>x</su

Effect of reactor design on the plasma treatment of NO<sub>x</sub>

Description: This paper presents the results of experiments in which various parameters were varied systematically in an attempt to understand how the reactor design affects the energy efficiency for plasma processing of NO <sub>x</sub> . These parameters include the packing material, electrode diameter, and voltage frequency. It is shown that the applied voltage is not the relevant parameter when comparing the performance of different plasma reactors. The important control parameter is the input energy density. In accordance with the observations reported by Penetrante et al. [<i>Applied Physics Letters</i> <b>68</b>, 3719-3721 (1996)], we have found that reactor design has little influence on the basic energy consumption of the plasma. Consequently, different reactor designs should yield basically the same plasma chemistry if the experiments are performed under identical gas composition and temperature conditions.

Effect of gas composition on the NO<sub>x</sub> conversion chemistry in a plasma

Description: Much work has been done on the application of plasmas to the treatment of NO<sub>x</sub> from power plants. In power plant applications, the purpose of the plasma is to oxidize NO to NO<sub>x</sub>, and eventually to nitric acid. The desires products, in the form of ammonium salts, are then obtained by mixing ammonia with the formed acids. Some form of scrubbing is required to collect the final products. For applications to the treatment of exhausts from cars and trucks, it is very important to make a distinction between NO removal by chemical oxidation and NO removal by chemical reduction. To avoid the need for scrubbing of plasma processing products, the desired method of NO removal is by chemical reduction; i.e., the conversion of NO to benign gaseous products like N NO<sub>2</sub>. This paper will discuss the results of an extensive series of experiments aimed towards understanding the effect of gas composition on the NO<sub>x</sub> conversion chemistry in a plasma. The NO<sub>x</sub> conversion chemistry in the presence of the individual components, such as N<sub>2</sub>, O<sub>2</sub>, H<sub>2</sub>O, and CO<sub>2</sub>, as well as the mixture of these, will be presented. We will show that, in a lean-burn gasoline or diesel engine exhaust, the main effect of the gas-phase reactions in a plasma is the oxidation of NO to NO<sub>x</sub> and nitric acid. To implement the reduction of NO<sub>x</sub> to N<sub>2</sub> in the highly oxidizing environment of a lean-burn engine exhaust, it will be necessary to prevent the formation of acid products and combine the plasma with another process that can chemically reduce NO<sub>2</sub> to N<sub>x</sub>.
