DOE management of high-level waste at the Hanford Site

Description: Approximately 60 million gallons of high-level radioactive waste--caustic liquids, slurries, saltcakes, and sludges--are stored in underground tanks at the Department of Energy`s Hanford Site. At least one-third of the tanks are known to have leaked waste into the enviroranent, and there are many unresolved tank safety issues. In order to resolve the environmental and safety concerns, the Department plans to retrieve the waste, immobilize it, and dispose of it in a permanent geologic repository… more

Gamma ray self attenuation correction factor study. Final report

Description: The overall focus of this work was an attempt to better understand the nature of self attenuating particles of SNM for the purpose of developing procedures for correcting for particle self attenuation relative to improving the quantitative non-destructive assay of these materials. This report is a summary of the various schemes, calculations, data and data analysis performed relative to this subject.

Hydrogen peroxide safety issues

Description: A literature survey was conducted to review the safety issues involved in handling hydrogen peroxide solutions. Most of the information found in the literature is not directly applicable to conditions at the Rocky Flats Plant, but one report describes experimental work conducted previously at Rocky Flats to determine decomposition reaction-rate constants for hydrogen peroxide solutions. Data from this report were used to calculate decomposition half-life times for hydrogen peroxide in solutions… more

Novel approaches to the production of higher alcohols from synthesis gas

Description: A detailed technical plan for research on higher-alcohol synthesis in a slurry reactor was prepared and approved internally, as part of the University's requirements for the doctoral degree. The focus of this plan is the high-pressure methanol synthesis catalyst, and modifications thereof. A major challenge of the research will be to identify a slurry medium that is stable at the typical operating temperature ofthis catalyst, i.e., about 400[degrees]C. Two shakedown runs were made in the stirre… more
