Abstract:

Porous plates delivered calcium chloride at a negative potential to the top of blocks of partially welded (20.1 x 20.1 x 66.6 cm) and densely welded (30.1 x 20.1 x 48.1 cm) tuff with discrete fractures. During infiltration, flux increased through the partially welded block's fracture as the applied suction was lowered to 2.3 cm. The wetting front advanced 66.6 cm in 239 days. Chloride concentration and temporal moments from five tracer tests with 0 to 5 cm of applied suction indicated that preferential fracture flow occurred. Displacement transducer data reflect a decrease in fracture aperture

Abstract:

This study examines the relationship between atomic energy production and community identity in Richland, Washington. Over the past fifty years, the identity of southeastern Washington has been intimately tied to production and industry at the Hanford Site. Today, however, environmental restoration and waste management programs have replaced plutonium production. The decline of the nuclear industry has influenced reinterpretations of local history and community identity through public display, commodity goods, and the re-scripting of historical texts.<br>Department of Anthropology

Abstract:

The purpose of this thesis is to explore the distributional side of environmental risks and burdens and, more particularly, to explain the significance of including intergenerational and intragenerational equity concerns within the fashioning of a legal regime governing the transboundary movement of radioactive waste. The thesis focuses on fairness and equity considerations between generations (intergenerational equity) and within contemporary generations (intragenerational equity) in the context of transboundary movements of radioactive wastes.

Abstract:

The disposal of waste is a growing environmental, political, and economic problem. Low level radioactive waste (LLW) disposal is no exception. The major purposes of this dissertation are to examine the economic tradeoffs which arise in the process of LLW disposal and to derive a framework within which the impact of these tradeoffs on LLW disposal policy can be analyzed. There are two distinct stages in the disposal of LLW--the transportation of the waste from sources to disposal sites and the disposal of the waste. The levels of costs and risks associated with these two stages depend on the nu

The purpose of the project was to determine the effect of various petroleum amendments on the migration rate of Cu. The petroleum amendments used in this research are frequently added to the soil surface in petroleum landfarming. Such petroleum wastes often contain significant amounts of Cu and other metals.Soil columns were amended with citric acid, used crankcase oil and Illinois crude oil. Each amendment was spiked (treated) with three different concentrations of Cu and each treatment was replicated three times. The columns were leached once per week, for ten weeks, with distilled water aci

Abstract:

In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA method, the activity concentrations are determined from the net counts of the windows set around individual &gamma<br>-ray peaks associated with the decay of U, Th and K. In the FSA method, the full energy spectrum is considered and the measured spectrum is described as the sum of the three standard spectra (associated with U, Th and K, respectively), each multiplied by an unk

The water quality above the landfill was high but decreased downstream. The water below the disposal site contained high levels of chemicals in both studies. However, the concentrations of chemicals were lower in the water two years after the cleanup.Numbers of macroinve

A gas-filled magnetic spectrometer (GFM) was proposed for the separation of 36Cl from its isobar, 36S. Semi-empirical Monte-Carlo ion optical calculations were conducted to define optimal conditions for separating 36Cl and 36S. A 180° GFM was constructed and installed at the dedicated AMS beam li
