High Order Finite Elements SN Transport in X-Y Geometry on Meshes with Curved Surfaces in the Thick Diffusion Limit

Creator:: Woods, Douglas N.
Abstract:: The high-order finite element S[subscript N] transport equations are solved on several test problems to investigate the behavior of the discretization method on meshes with curved edges in X-Y geometry. Simpler problems ensured the correct implementation of MFEM, the general fi nite element library employed. A convergence study using the...

Discrete Ordinates Radiation Transport using High-Order Finite Element Spatial Discretizations on Meshes with Curved Surfaces

Creator:: Woods, Douglas N.
Abstract:: We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...

Neutron Attenuation and Hydration of Cement Paste made with Light and Heavy Water

Creator:: Goodwin, Margaret N.
Abstract:: Neutron radiography has been used to study cementitious materials. This thesis studies the impact of heavy water on both the rate of hydration and neutron radiography. The neutron attenuation coefficients of light and heavy water were measured. Cement pastes were made with both heavy and light water. The attenuation coefficients...

Skin depth dose response of an ionization chamber and a thermo-luminescent dosimeter system using low energy X-rays

Creator:: Fowler, Adam (Adam James)
Abstract:: The use of Ionization Chambers and Thermo-luminescent dosimeters (TLD's) in the medical field has established a need to determine if the skin depth dose response is comparable between the two detectors. This research will determine if the dose response from an Ionization chamber is comparable to a Thermo-luminescent dosimeter system...

Comparison of Attila SN Particle Transport Code with MCNP in the Analysis of Small Modular Reactor Shielding

Creator:: Rose, Charlotte
Abstract:: Of great importance in the design of a nuclear power plant is the evaluation of shielding from the ionizing radiation produced in the core of the nuclear reactor. This requires simulation software to predict the dose rates in the areas of interest. Comparing the simulation of the same modeled system...

Development of a Fundamental Depth-Dependent Neutron Dosimetry Model

Creator:: Anspach, Logan J.
Abstract:: Current neutron dosimetry methods rely on the assumption that charged particle equilibrium (CPE) is established within the tissue medium. This maintains that the kinetic energy transferred to the medium (KERMA) is equivalent to absorbed dose. However, this assumption is only valid for large volumes such as the whole body. For...

Comparing Random and Nonrandom Spatial Patterns of Artifacts within Lithostratigraphic Unit 3 at Cooper’s Ferry, Idaho

Creator:: Gregory, Alex R.
Abstract:: Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...

Material Expressions of Class, Status and Authority amongst Commissioned Officers at Fort Yamhill and Fort Hoskins, Oregon, 1856-1866

Creator:: Eichelberger, Justin E.
Abstract:: During the 19th century the United States Army was a military institution characterized by a hierarchical system of authoritative, social and economic inequality between members of its different military grades. Although necessary for insuring military discipline within the Army this system of inequality also influenced the non-military social lives of...

Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

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...
