MCNP5 modeling of the Oregon State TRIGA Reactor for skyshine dose estimation after a loss of coolant accident

Creator:: Sarmast, Katharine Danielle
Abstract:: This thesis evaluates dose rates from the TRIGA® reactor by comparing ion chamber measured exposure rates to exposure rates calculated from MCNP5 model data. The first step evaluates the energy distribution required to match ion chamber exposure rates from measurements taken at 1 foot increments above the reactor core. Next,...

The Environmental, Economic, and Social Factors that Contribute to the Importance of the Pacific Razor Clam (Siliqua patula) Fishery for Oregon Coastal Communities: A Northern Oregon Case Study

Creator:: Baker, Laura C.
Abstract:: Pacific razor clams (Siliqua patula) are narrow oblong bivalves that can be found in sandy habitats along the western coast of the United States, from Alaska (Aleutian Islands) to southern California (Pismo Beach). In Washington state, the razor clam fishery has been documented to be an important contributor to the...

Describing the thermal regimes of two northeastern Oregon streams

Creator:: Raven, Sonja E.
Abstract:: Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....

The Pursuit of Hoppiness : Propelling Hop into the Genomic Era

Creator:: Hill, Steven T.
Abstract:: Hop (Humulus lupulus L. var lupulus) is a plant of great cultural significance, used as a medicinal herb for thousands of years, and for flavor and as a preservative in brewing beer. Studies of the medicinal effects of the unique compounds produced by hop have led to interest from the...

Geomorphic and Climatic Controls on Water Temperature and Streambed Scour, Copper River Delta, Alaska : Implications for Understanding Climate Change Impacts to the Pacific Salmon Egg Incubation Environment

Creator:: Adelfio, Luca A.
Abstract:: Pacific salmon (Oncorhynchus spp.) face numerous challenges associated with climate change. Most research has emphasized the potential effects of elevated summer water temperatures; however, climatic changes are also projected to significantly alter incubation and rearing habitats during the late autumn, winter, and spring months ("the incubation period"). Along the southern...

A novel linear generator for wave energy applications

Creator:: Ernst, Steven George
Abstract:: With the increasing effort to identify alternative methods of energy generation, extraction of ocean energy has gathered a large interest. Research and industry have begun considering wave energy as the next new alternative energy. The unique challenges of ocean energy requires a wave energy converter to be both robust and...

The impact of physical and biological properties on the erodibility of sediments along the western Adriatic Sea, Italy

Creator:: Stevens, Andrew W.
Abstract:: During two cruises in February and June of 2003, the erodibility of sediment along the western Adriatic Sea was measured using a "Gust erosion chamber". In addition, the surficial sediment properties were characterized through a suite physical and biological measurements including porosity, grain-size, inorganic carbon, organic carbon and colloidal carbohydrate....

MCNP 6 Simulations of Short-Lived, Low-Yield Fission Byproducts, Gamma-Ray Spectrometry, and their Comparison to Natural Uranium Measurements for the Evaluation of Available Evaluated Nuclear Data Files

Creator:: Jeffries, Tanner D.
Abstract:: Natural uranium samples were irradiated in-core for 7 seconds using the pneumatic rabbit system within the TRIGA Mark II Reactor at Oregon State University, and then used to generate a gamma-ray spectrum with a high purity germanium (HPGe) detector. The irradiated sample was simulated in Monte Carlo N-Particle (MCNP), a...

Growth, morphology, and in vitro development of transgenic poplars with RNAi-inhibited PtDDM1-1/2 gene expression

Creator:: Zhu, Ruoqing
Abstract:: Epigenetic mechanisms are important for control of plant development, and may play a particularly important role in trees given their long life cycles and distinctive and stable tissue types. To help understand the role of epigenetics in tree development, we produced transgenic poplars with reduced activity of the DDM1 genes,...

Neutron radiography and tomography : determining and optimizing resolution of neutron sensitive multi channel plate detectors

Creator:: Williams, Walter James
Abstract:: The objective of this work was to determine and optimize the resolution of a neutron sensitive Multi-Channel Plate (MCP) detector in order to determine its capabilities in radiography and tomography. The Oregon State University, Neutron Radiography Facility added an MCP Detector in 2012 in order to analyze these capabilities. The...
