Weldability of High Alloys

Description: The purpose of this study was to investigate the effect of silicon and iron on the weldability of HAYNES HR-160{reg_sign} alloy. HR-I60 alloy is a solid solution strengthened Ni-Co-Cr-Si alloy. The alloy is designed to resist corrosion in sulfidizing and other aggressive high temperature environments. Silicon is added ({approx}2.75%) to promote the formation of a protective oxide scale in environments with low oxygen activity. HR-160 alloy has found applications in waste incinerators, calciners… more

Advanced Vehicle Testing Activity: Low-Percentage Hydrogen/CNG Blend Ford F-150 Operating Summary - January 2003

Description: Over the past two years, Arizona Public Service, a subsidiary of Pinnacle West Capital Corporation, in cooperation with the U.S. Department of Energy's Advanced Vehicle Testing Activity, tested four gaseous fuel vehicles as part of its alternative fueled vehicle fleet. One vehicle operated initially using compressed natural gas (CNG) and later a blend of CNG and hydrogen. Of the other three vehicles, one was fueled with pure hydrogen and two were fueled with a blend of CNG and hydrogen. The thr… more

XFD progress report.

Description: In May 2002, the Advanced Photon Source (APS) was reorganized into three divisions: the Accelerator Systems Division (ASD), the APS Operations Division (AOD), and the Experimental Facilities Division (XFD). Parts of the former User Program Division (UPD) were incorporated into XFD; other parts were incorporated into AOD. This Progress Report summarizes the main scientific and technical activities of XFD and parts of the former UPD from January 2001 through June 2002. The report is divided into … more

Regulation of new depleted uranium uses.

Description: This report evaluates how the existing U.S. Nuclear Regulatory Commission (NRC) regulatory structure and pending modifications would affect full deployment into radiologically uncontrolled areas of certain new depleted uranium (DU) uses being studied as part of the U.S. Department of Energy's DU uses research and development program. Such new DU uses include as catalysts (for destroying volatile organic compounds in off-gases from industrial processes and for hydrodesulfurization [HDS] of petro… more

Tuning of laser pulse shapes in grating-based compressors for optimal electron acceleration in plasmas

Description: The temporal shape (rise time, fall time, skewness) of 50 - 200-fs Ti:sapphire laser pulses has been controlled by appropriate adjustment of a grating-pair compressor. It was found that the skewness of the laser pulse envelope is particularly sensitive to the third-order component of the spectral phase. Introducing such a third-order phase offset by detuning the grating pair relative to the optimum pulse compression settings allowed the generation of skewed pulses. As an example of an applicati… more

Crystallization of a member of the recFOR DNA repair pathway, RecO, with and without bound oligonucleotide

Description: RecFOR proteins are important for DNA repair by homologous recombination in bacteria. The RecO protein from Thermus thermophilus was cloned, purified and characterized for its binding to oligonucleotides. The protein was crystallized alone and in complex with a 14-mer oligonucleotide. Both crystal forms grow under different crystallization conditions in the same space group, P3121 or P3221, with almost identical unit cell parameters. Complete data sets were collected to 2.8 Angstrom and 2.5 Ang… more

STUDIES ON THE RCMS RF SYSTEM.

Description: This note addresses the various options for the Rapid Cycling Medical Synchrotron (RCMS) RF. The study was divided into three cases, namely non-tuning, tuning and filter. Each case also includes a few options. The primary study was focused on the non-tuning options. However, it was found that it requires too much driver power to cover the wide band and thus causes the cost being too high to be competitive. The proposal of RCMS is not yet clear if it can be approved or not. The results of this s… more

A Case Study of Selected Photographic Inspection Techniques for a Transparency Regime

Description: Photographic inspection techniques have become technically more sophisticated in recent years with the development of advanced equipment for the mass consumer market. High quality digital cameras, for example, are now available around the world. Combined with an appropriate image analysis program on a personal computer, there is now the ability to produce and analyze high quality photographs with a modest level of resources. This report is the summary of a variety of efforts, all aimed at inves… more

House and Senate Vacancies: How Are They Filled?

Description: This report discusses how vacancies in Congress are filled when a Senator or Representative dies, resigns, declines to serve, or is expelled or excluded from either house. The Constitution requires that vacancies in both houses be filled by special election, but in the case of the Senate, it empowers state legislatures to provide for temporary appointments by the state governor until special elections can be scheduled.

EMSP Final Report: Electrically Driven Technologies for Radioactive Aerosol Abatement

Description: The purpose of this research project was to develop an improved understanding of how electrically driven processes, including electrocoalescence, acoustic agglomeration, and electric filtration, may be employed to efficiently treat problems caused by the formation of aerosols during DOE waste treatment operations. The production of aerosols during treatment and retrieval operations in radioactive waste tanks and during thermal treatment operations such as calcination presents a significant prob… more
