Tc-99 Analysis with Picogram Sensitivity by a Resin-Bead Mass-Spectrometric Isotope-Dilution Technique (open access)

Tc-99 Analysis with Picogram Sensitivity by a Resin-Bead Mass-Spectrometric Isotope-Dilution Technique

This paper describes an improved isotope-dilution mass-spectrometric procedure. Important improvements are a highly selective (yet non-critical) isolation scheme devised primarily from the work of Maeck, et al. and a significant increase in the mass spectrometric ionization efficiency for technetium obtained by analyzing the technetium absorbed on individual anion exchange resin beads.

Oral History Interview with William C. Beyer, March 14, 2001

The National Museum of the Pacific War presents an oral interview with William C. Beyer. Beyer grew up in Texas and joined the Marines in January 1942. After training, he was assigned to the third division in artillery. He departed on the USS Mount Vernon for New Zealand. He anecdotes about meeting with some Maori people. Then he departed on the Cresent City for Guadalcanal in May 1943. From Guadalcanal he left for Bougainville in November 1943. He describes being caught in a foxhole for two days without communication. He also listened to Tokyo Rose on the radio. The Army relieved the Marines January 15, 1944, and his unit returned to Guadalcanal. On July 21, 1944, they landed on Guam and went into battle. Next Beyer left for Iwo Jima. The Third Marine Division was assigned to the central area of the island. He witnessed the raising of the flag. On the 50th anniversary of the war, Beyer and his wife returned to New Zealand and Guam.

Effect of Internal Alpha Radiation on Borosilicate Glass Containing Simulated Radioactive Waste (open access)

Effect of Internal Alpha Radiation on Borosilicate Glass Containing Simulated Radioactive Waste

To evaluate borosilicate glass as a matrix for long-term storage of radioactive waste, samples containing 45 wt. percent simulated waste along with 0.5 wt. percent 244Cm or 1 wt. percent 238Pu as alpha particle emitters were synthesized. A glass containing 238Pu without simulated waste was also made. Effects of internal alpha radiolysis from 244Cm and 238Pu on physical stability, leachability, and dilatation of the glasses were examined. Results confirm that glass may be a desirable matrix for fixing SRP radioactive waste for long-term storage. Internal alpha radiolysis and helium accumulation in the small samples did not significantly damage the glass. Actual values for helium solubility and permeability would be necessary, however, to determine whether helium accumulation might eventually damage larger glass monoliths during long-term storage.

Gas Generation from K East Basin Sludges - Series II Testing (open access)

Gas Generation from K East Basin Sludges - Series II Testing

This report describes work to examine the gas generation behavior of actual K East (KE) Basin floor, pit and canister sludge. Mixed and unmixed and fractionated KE canister sludge were tested, along with floor and pit sludges from areas in the KE Basin not previously sampled. The first report in this series focused on gas generation from KE floor and canister sludge collected using a consolidated sampling technique. The third report will present results of gas generation testing of irradiated uranium fuel fragments with and without sludge addition. The path forward for management of the K Basin Sludge is to retrieve, ship, and store the sludge at T Plant until final processing at some future date. Gas generation will impact the designs and costs of systems associated with retrieval, transportation and storage of sludge.

A Cartesian grid embedded boundary method for the heat equation on irregular domains (open access)

A Cartesian grid embedded boundary method for the heat equation on irregular domains

We present an algorithm for solving the heat equation on irregular time-dependent domains. It is based on the Cartesian grid embedded boundary algorithm of Johansen and Colella (J. Comput. Phys. 147(2):60--85) for discretizing Poisson's equation, combined with a second-order accurate discretization of the time derivative. This leads to a method that is second-order accurate in space and time. For the case where the boundary is moving, we convert the moving-boundary problem to a sequence of fixed-boundary problems, combined with an extrapolation procedure to initialize values that are uncovered as the boundary moves. We find that, in the moving boundary case, the use of Crank--Nicolson time discretization is unstable, requiring us to use the L{sub 0}-stable implicit Runge--Kutta method of Twizell, Gumel, and Arigu.

The Effect of Thermo-mechanical Processing on the Mechanical Properties of Molybdenum-2 Volume%Lanthana (open access)

The Effect of Thermo-mechanical Processing on the Mechanical Properties of Molybdenum-2 Volume%Lanthana

Variations in oxide species and consolidation method have been shown to have a significant effect on the mechanical properties of oxide dispersion strengthened (ODS) molybdenum material. The mechanical behavior of molybdenum - 2 Volume % La[sub]2O[sub]3 mill product forms, produced by a wet doping process, were characterized over the temperature range of -150 degrees C to 1800 degrees C. The various mill product forms evaluated ranged from thin sheet stock to bar stock. Tensile properties of the material in the various product forms were not significantly affected by the vast difference in total cold work. Creep properties, however, were sensitive to the total amount of cold work as well as the starting microstructure. Stress-relieved material had superior creep rupture properties to recrystallized material at 1200 degrees C, while at 1500 degrees C and above the opposite was observed. Thus it is necessary to match the appropriate thermo-mechanical processing and microstructure of molybdenum - 2 volume % LA[sub]2O[sub]3 to the demands of the application being considered.

Seeing atoms only 0.78A apart (open access)

Seeing atoms only 0.78A apart

The one-Angstrom microscope (OAM) project at the USDOE's National Center for Electron Microscopy has extended the limits of high-resolution transmission electron microscopy to sub-Angstrom levels. The OAM combines image-processing software with a modified 300keV electron microscope equipped with a highly-coherent field-emission electron gun. We have found that a reduction in the OAM's electron-gun extraction voltage allows us to ''see'' silicon atoms separated by only 0.78A.

Pipeline Safety: Federal Program and Reauthorization Issues (open access)

Pipeline Safety: Federal Program and Reauthorization Issues

The 107th Congress is considering legislation that would amend federal pipeline safety law, which directs the U.S. Secretary of Transportation to regulate pipeline transportation and storage of natural gases and hazardous liquids. Those bills also would authorize funding for the Office of Pipeline Safety (OPS) of the U.S. Department of Transportation (DOT), which is charged with implementing federal pipeline safety law. Among the topics discussed as part of the process of reauthorizing the OPS program are: state versus federal roles in pipeline safety, increased community involvement, funding amounts to support OPS, and new regulatory directives and authorities intended to improve the OPS program and associated state activities. S. 235, as amended, the "Pipeline Safety Improvement Act of 2001," passed the Senate on February 8, 2001. This report will be updated as necessary.

Reducing Emissions of Volatile Organic Compounds - Final Report - 08/15/1997 - 02/14/2001 (open access)

Reducing Emissions of Volatile Organic Compounds - Final Report - 08/15/1997 - 02/14/2001

The overall objective of this research was to determine if the shallow suspended growth reactor (SSGR) could provide sufficient treatment performance of organic and reduced sulfur (TRS) compounds, at 50 C to meet the EPA ''cluster rule'' regulatory limits. The biodegradation of a mixture of organic compounds that could be present in pulp and paper high volume low concentration gas streams was evaluated at 50 C in a bench-scale SSGR. The removal of methanol was followed in particular, and was mathematically modeled to evaluate the effect of process design and operating parameters on methanol removal. Additional tests were performed to obtain mass transfer and biodegradation kinetic parameters for the model. The acclimation of microbial populations capable of degrading TRS compounds from various seed sources was studied in batch reactors at 30 and 50 C. The degradation of TRS compounds in bench-scale SSGR was studied at 20-50 C. Also, the biodegradation kinetic and mass transfer coefficients for alpha-terpinene and gamma-terpinene were studied. Finally, a pilot plant was constructed and operated at Simpson pulp and paper mill in Tacoma, WA.
