1: Mass asymmetric fission barriers for {sup 98}Mo; 2: Synthesis and characterization of actinide-specific chelating agents

Description: Excitation functions have been measured for complex fragment emission from the compound nucleus {sup 98}Mo, produced by the reaction of {sup 86}Kr with {sup 12}C. Mass asymmetric fission barriers have been obtained by fitting the excitation functions with a transition state formalism. The extracted barriers are {approximately} 5.7 MeV higher, on average, than the calculations of the Rotating Finite Range Model (RFRM). These data clearly show an isospin dependence of the conditional barriers whe… more

A 20 ampere shunt regulator for controlling individual magnets in a seriesed string

Description: At the CEBAF accelerator, groups of dipole magnets are often connected together in series and powered from a single large constant-current regulated D-C supply, referred to locally as a {open_quotes}box{close_quotes} supply. Besides the economy realized, this configuration promotes correct field tracking of all elements of a beam transport channel. However, it is often desirable to vary the current in one element of a string independently of the others, particularly at the entrance and exits of… more

222-S Analytical services final results for Tank 241-U-101, grab samples 1U-96-1 through 1U-96-4

Description: This document is the final, format IV, laboratory report for characterization of tank 241-U-101 (U-101) grab samples from risers 1 and 7. It transmits additional analytical data for specific gravity (Sp.G.), and all raw analytical data which were not provided in the 45-day report. The 45-day report is attached to this final report as Part II. Secondary analyses were not performed on any of the U-101 samples. This is because none of the primary analyte limits, which trigger the performance of se… more

340 Representative sampling verification tank sampling and analysis plan

Description: This Sampling and Analysis Plan contains requirements for characterizing the 340 vault tank 1. The objective of the sampling and characterization is to determine if the tank is homogeneous when agitated and which sampling method provides the most representative sample. A secondary objective is to collect and characterize solid samples.

Action plan for response to excessive temperatures in Hanford site high-heat waste tank 241-C-106

Description: Tank 241-C-106 is a single shell tank at the Hanford Site in south central Washington State, and is the only tank on Hanford`s High-Heat Tank Watch List. This action plan defines possible abnormal conditions (such as ventilation system failure or a leaking tank) that could lead to excessive temperature increases in tank 241-C-106, and documents pre-planned contingency actions would effectively mitigate the consequences of such increased temperatures. Potential structural damage may result from … more

Adsorption and desorption of sulfur dioxide on novel adsorbents for flue gas desulfurization. Final report, September 1, 1994--February 29, 1996

Description: A sol-gel granulation method was developed to prepare spherical {gamma}-alumina granular supports and supported CuO granular sorbents for flue gas desulfurization. The prepared {gamma}-alumina supported CuO sorbents exhibit desirable pore structure and excellent mechanical properties. The sorbents contain higher loading (30-40 wt. %) of CuO dispersed in the monolayer or sub-monolayer form, giving rise to a larger SO{sub 2} sorption capacity ({gt}20 wt.%) and a faster sorption rate as compared t… more

Advanced computer techniques for inverse modeling of electric current in cardiac tissue

Description: For many years, ECG`s and vector cardiograms have been the tools of choice for non-invasive diagnosis of cardiac conduction problems, such as found in reentrant tachycardia or Wolff-Parkinson-White (WPW) syndrome. Through skillful analysis of these skin-surface measurements of cardiac generated electric currents, a physician can deduce the general location of heart conduction irregularities. Using a combination of high-fidelity geometry modeling, advanced mathematical algorithms and massively p… more

Advanced direct liquefaction concepts for PETC generic units phase II. Quarterly technical progress report, April--June 1996

Description: A catalyst screening test (CST) was developed to evaluate the activity of various catalyst precursors for their liquefaction activity in a solvent comprising the solids-free components of a recycle solvent generated at Wilsonville, namely a ROSE SR V-130 deashed resid from period A and V-1074 heavy distillate from period B. Since the deashed resid has an elemental composition very nearly the same distillate from period B. Since the deashed resid has an elemental composition very nearly the same… more

Advanced thermally stable jet fuels. Technical progress report, January 1996--March 1996

Description: A reactive structure index was developed to correlate the molecular structures of saturated hydrocarbons with their reactivities using a linear group contribution method. The index is composed of several sub-indices determined from the structure, including carbon group indices, ring index, and conformation index. The effects on decomposition of ring structure, side-chain length, steric isomers, and branching were examined. Good correlations were obtained for two sets of saturated hydrocarbons. … more

Advanced Turbine Systems (ATS) program conceptual design and product development

Description: Achieving the Advanced Turbine Systems (ATS) goals of 60% efficiency, single-digit NO{sub x}, and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NO{sub x} emission. Improved coatings and materials technologies along with creative combust… more

Advances in excimer laser processing of materials

Description: The use of pulsed excimer lasers to surface processing of materials hinges on an understanding of the nature of the interaction between the laser energy and the material. The application of this understanding of the laser materials interaction to surface modification must also recognize the existence of thermodynamic driving forces and kinetic limitations in light of the short duration of a single pulse event. For species that have higher solubility in the liquid than in the solid phase, segreg… more
