Biscuit Fire: Analysis of Fire Response, Resource Availability, and Personnel Certification Standards

Description: A letter report issued by the General Accounting Office with an abstract that begins "In 2002, the United States experienced one of the worst wildland fire seasons in the past 50 years--almost 7 million acres burned. These fires included the largest and costliest fire in Oregon in the past century--the Biscuit Fire. Following a lightning storm, five fires were discovered in the Siskiyou National Forest over a 3- day period beginning July 13. These fires eventually burned together to form the Bi… more

Carbon Steel and Magnesium Oxide Dissolution for H-Canyon Process Applications

Description: H Area Operations is planning to process plutonium-contaminated uranium metal scrap in its efforts to de-inventory excess nuclear materials. The Savannah River Technology Center (SRTC) performed flowsheet development to support the decision to process the scrap in H-Canyon using 2M nitric acid (HNO3) / 0.025M potassium fluoride (KF) and 2 g/L boron. The scrap will be charged to the H-Canyon dissolver via a stainless steel charging bundle with a carbon steel end cap that must dissolve in an appr… more

DETECTION OF UNAUTHORIZED CONSTRUCTION EQUIPMENT IN PIPELINE RIGHT-OF-WAYS

Description: Natural gas transmission companies mark the right-of-way areas where pipelines are buried with warning signs to prevent accidental third-party damage. Nevertheless, pipelines are sometimes damaged by third-party construction equipment. A single incident can be devastating, causing death and millions of dollars of property loss. This damage would be prevented if potentially hazardous construction equipment could be detected, identified, and an alert given before the pipeline was damaged. The Gas… more

Dissolution of Plutonium Scrub Alloy and Anode Heel Materials in H-Canyon

Description: H-Canyon has a ''gap'' in dissolver operations during the last three months of FY03. One group of material to be processed during the gap is pre-existing scrub alloy material. There are 14 cans of material containing approximately 3.8 kilograms of plutonium. Of the 14 cans, it was anticipated that four cans contain salts, two cans contain anode heel materials, and eight cans contain scrub alloy buttons. H-Canyon desires to process the materials using a flowsheet similar to the SS and C (sand, s… more

Hanford Site Groundwater Monitoring for Fiscal Year 2003

Description: This report presents the results of groundwater and vadose zone monitoring and remediation for fiscal year 2003 (October 2002 through September 2003) on the U.S. Department of Energy's Hanford Site, Washington. The most extensive contaminant plumes in groundwater are tritium, iodine-129, and nitrate, which all had multiple sources and are very mobile in groundwater. The largest portions of these plumes are migrating from the central Hanford Site to the southeast, toward the Columbia River. Conc… more

INTERNAL REPAIR OF PIPELINES

Description: The two broad categories of deposited weld metal repair and fiber-reinforced composite liner repair technologies were reviewed for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Preliminary test programs were developed for both deposited weld metal repair and for fiber-reinforced composite liner repair. Evaluation tria… more

Reaching sub-Angstrom resolution with a mid-voltage TEM

Description: Phase-contrast imaging in the high-resolution electron microscope produces images with peaks at atom positions by extracting the spatial distribution of the relative phase from the electron wave. Usually, the electron wave is imaged by direct interference of diffracted beams at optimum focus. Instead, the One-Angstrom Microscope uses focal-series reconstruction software to derive the relative electron phase from a series of images taken over a range of focus, with peaks that correspond to the a… more

Reactions of Atoms and Radicals in Pulsed Molecular Beams

Description: The final report describes studies of unimolecular reactions of transient species and radicals relevant to combustion processes. Specifically, the dynamics of predissociation of free radicals for which multiple pathways, including molecular rearrangements, compete. These small, prototypical, systems are amenable to treatment by high level theory, and close collaboration with theory continues to be a cornerstone of the program. The chemistry of hydroxyalkyl radicals is important in atmospheric a… more

Statistical Analysis of Elevated Radium and Gross Alpha Measurement in the Sanitary Landfill

Description: In 2002, radium 226 and 228 measurements elevated above the 5 pCi/L groundwater protection standard (GWPS) and gross alpha measurements above the 15 pCi/L GWPS were noticed in several groundwater monitoring wells at the SRS Sanitary Landfill. An additional four quarters of confirmatory measurements for Ra in the SLF groundwater were taken during 2003 as directed by the SC Department of Health and Environmental Control. Elevated radium concentrations in groundwater of the Aiken County area are a… more

Summary of Hanford Site Groundwater Monitoring for Fiscal Year 2003

Description: This document is a summary of the larger report, PNNL-14548. It describes the groundwater monitoring results for FY 2003 at the Hanford Site in southeast Washington State. The Hanford Site, a facility in the U.S. Department of Energy (DOE) nuclear weapons complex, encompasses {approx}1,517 square kilometers northwest of the city of Richland along the Columbia River in southeast Washington State. The federal government acquired the site in 1943, and until the 1980s it was dedicated primarily to … more
