Insight into Western Stemmed Tradition cultural patterns based on analysis of Pit Feature 95 at the Cooper's Ferry Site (10IH73), Idaho

Creator:: McPherson, Gabrielle
Abstract:: Excavations at the Cooper’s Ferry site (10IH73) revealed a long record of repeated human occupation extending from the late Pleistocene into the early Holocene (~16,000-10,000 cal BP) and have yielded unique insights into the Western Stemmed Tradition (WST), which includes. Several studies have focused on WST pit features encountered at...

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...

Archaeological Textile Fragments Present an Opportunity In the Study of Social and Landscape Interactions

Creator:: Lopez, Kirsten M.
Abstract:: Textiles (including basketry, cordage, woven, knotted, or plaited products) make up a considerable portion of the perishable archaeological record in dry caves of the northern Great Basin region, much of which is created from plants and plant fibers. The archaeological study of precontact textiles greatly informs our understanding of how...

Feasibility Study on MHD Energy Conversion for Applications in Liquid Metal Cooled Nuclear Reactors

Creator:: Qiu, Hanrui
Abstract:: The application of two-phase magnetohydrodynamic(MHD) in liquid metal cooled nuclear reactors presents opportunities to simplify the power generation system by eliminating moving components like a turbine for enhanced safety. The proposed system in this thesis consists of two loops with immiscible working ﬂuids. The compressed gas expands in the two-phase...

On the mechanism transition of power transient critical heat flux

Creator:: Yan, Yikuan
Abstract:: The reactivity-initiated accident (RIA) accident has stirred wide interest for the need of designing advanced and high tolerance fuels for next generation nuclear power plants. For pressurized water reactors (PWRs), the accidentally induced reactivity pulse adds transient energy input to the fuel. As a result, boiling may happen locally. Boiling...

Dosimetry Model for Alpha Emitters in a Radioactive Skin Patch for Treatment of Early-Stage Nonmelanoma Skin Cancers

Creator:: Squillante, Joyce
Abstract:: Nonmelanoma skin cancer (NMSC) is the most common malignancy in Caucasian populations. One existing treatment modality for NMSCs is external radiotherapy delivered to the skin cancer tumor by a beta-emitter-containing radioactive skin patch. Alpha emitters, with their higher linear energy transfer than beta particles and shorter range in tissue, make...

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...

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...

A Theoretical Model for Spherical Cap Bubble Geometry

Creator:: Wieland, Isaiah T.
Abstract:: The significant variation in bubble geometry, as a function of size, has fascinated scientists for hundreds of years. However, a comprehensive explanation for these observations and the underlying physics has eluded researchers. A theoretical model which describes a the relationship between forces that produce spherical cap bubble geometry has been...

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...
