Establishment of concentration ratios for riparian and shrub steppe areas of the eastern Washington Columbia basin

Creator:: Napier, Jonathan Bamberger
Abstract:: Concentration ratios are used to determine the transfer of nuclides from soil to biota to fauna. Some nuclides have limited associated data though, this has not prevented predictions from being performed at sites without associated data. These ratios are site specific and are not fully applicable when applied to other...

Development of a Fast Spectrum Test Loop at the Advanced Test Reactor

Creator:: Higgins, Anton
Abstract:: The United States currently has no infrastructure to provide a fast neutron flux for research purposes. With the increased interest in Sodium Fast Reactor (SFR) technology, this type of infrastructure is necessary for further development of key components such as Versatile Test Reactor. The purpose of this research is to...

Analysis of Asymmetric Heating on a Scaled High Temperature Gas Reactor Experiment During a Pressurized Conduction Cooldown

Creator:: Moore, Thomas
Abstract:: Among the candidates for the next generation of nuclear power plant is the high temperature gas reactor (HTGR). Since the HTGR does not have the same operational history as water cooled reactors do in the United States, investigation into the response of different accident phenomena is still an active area...

Development of a Novel MEMS Thermal Sensor Array for Pebble Bed HTGRs

Creator:: Hertel, Matthew A.
Abstract:: A novel high temperature thermal instrument is proposed, which utilizes a dual-sensing platinum resistor encased in a mono-crystalline alpha-alumina (sapphire) substrate. The instrument is comprised of four platinum trace elements, oriented with 90° rotational symmetry atop a 1120 oriented crystal lattice substrate. All four of these sensors measure temperature directly...

Thermal hydraulic and fuel performance analysis for innovative small light water reactor using VIPRE-01 and FRAPCON-3

Creator:: Mai, Anh T.
Abstract:: The Multi-Application Small Light Water Reactor (MASLWR) is a small natural circulation pressurized light water reactor design that was developed by Oregon State University (OSU) and Idaho National Engineering and Environmental Laboratory (INEEL) under the Nuclear Energy Research Initiative (NERI) program to address the growing demand for energy and electricity....

Investigation of Drag Coefficient and Virtual Mass Coefficient on Rising Ellipsoidal Bubbles

Creator:: Dueñas, Alexander M.
Abstract:: Accurately describing drag and virtual mass forces in two-phase flows is crucial for high fidelity modeling of nuclear thermal hydraulic safety systems. This study compares existing drag coefficient correlations commonly used in computational fluid dynamics (CFD) applications for air bubbles to experimental data collected for ellipsoidal air bubbles of varying...

Development of a binary mixture gas composition instrument for use in a confined high temperature environment

Creator:: Cadell, Seth R.
Abstract:: With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities...

A New Approach of Computational Fluid Dynamics Studying Power Transient Critical Heat Flux

Creator:: Chen, Tsung-Wen
Abstract:: Power transient boiling has been studied for decades, however, the mechanistic understanding of phenomena which occur during such an event remains incomplete. Due to a dearth of systematic researches, the information of studied phenomenon, detailed physics and applicable hypothesis are very limited. Transient critical heat flux (CHF) is paramount in...

A Game of Silent Irreverence : Passive Resistance in The Dalles, Oregon

Creator:: Maddoux, Maryanne
Abstract:: 210 East First Street (site 35WS453) contains the only extant remains of a once thriving Overseas Chinese settlement, in the city of The Dalles, Oregon. Very little is known about the everyday lives of these early settlers, or the pressures that they faced. This thesis will help to enrich the...

Caution! High Water: A Historical Archaeological Investigation of the Champoeg Townsite (ORMA26) after the 1861 Flood

Creator:: Hill, Cayla L.
Abstract:: The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...
