The Modeling of Core-Wide Behavior of Pebble Bed Reactors Using Static and Dynamic Graphite Pebble Properties to Predict Core Performance and Safety Behaviors

Creator:: Cox, Jordan T.
Abstract:: The United States Department of Energy has identified the pebble-bed reactor as a high priority for US research with the end goal of licensing a pebble-bed reactor (PBR) for operation in the United States. Before this can be accomplished significant research must be done regarding the safety of the pebble-bed...

Manufacturing Process Design for a Stamped Microchannel High-Temperature Recuperator

Creator:: Song, Chuankai
Abstract:: Microchannel high temperature recuperators have the advantage of higher heat transfer coefficients and lower size and weight than traditional high temperature recuperators. However, the industrial application of microchannel recuperators are restricted by the high cost of photochemical machining and diffusion bonding. The objective of this paper is to introduce a...

Usage of Digital Image Correlation in Single and Multiple Stereo Systems for Strain and Shape Measurement

Creator:: McKinley, Timothy A.
Abstract:: This dissertation details the application of digital image correlation (DIC) in novel methods for mechanical testing and shape characterization. The first usage manifested in the development of a novel composite test specimen that provided the ability to characterize the matrix compression energy release rate at initiation and subsequent crack propagation....

Development of a Strain Gage Program for the Measurement of Strain on Prototypic, Plate-type, High Performance Research Reactor Fuels under Flow Testing

Creator:: Weiss, Aaron W.
Abstract:: A large, multi-year experimental program has been conducted to develop a strain gaging program for application to the flow testing of prototypic, plate-type fuel for high performance research reactors. This test program has resulted in the selection of appropriate strain gage construction, adhesives, and protective coatings to allow the acquisition...

Computational modeling of a diffusion bonded microchannel under high pressure and temperature

Creator:: Pratte, William
Abstract:: Diffusion bonded microchannels provide significant benefits by reducing space requirements while improving thermal efficiency when used in heat exchangers. In particular, these microchannels have potential to improve efficiencies for combining concentrated solar power with supercritical CO2 Brayton cycles, where structures operate at high temperatures (760 ˚C) and high pressures (25...

An Approach to Modeling Fuel Plate Deformations in Fluid-Structure Interactions

Creator:: Howard, Trevor
Abstract:: As computational power increases, so does the desire to use fluid-structure interaction (FSI) software to design complex systems and components such as fuel plates. Presently, an effort is underway to support the design and qualification of a new nuclear fuel material which is intended for applications in select, plate-type, research...

Development of a Rapid Power Transient Critical Heat Flux Model

Creator:: Brown, Emory G.
Abstract:: The understanding of critical heat flux is crucial for the safety of nuclear reactors. To this end, many studies have been carried out to understand various aspects of the boiling crisis phenomenon. Power transient critical heat flux trigger mechanisms is a small category that is relatively under-studied and not well...

Quantifying System Similarity Between EBR-II and the VTR Integral Test Facility Through Hierarchical Two-Tiered Scaling and RELAP5 Simulations

Creator:: Leitherer, Brett C.
Abstract:: Advanced reactor designs offer many advantages over typical Light Water Reactors (LWRs) including fast neutron capability, passive safety features, and improved performance. While the future for these reactors seems promising, operating and test experience is necessary to further validate such claims. The development of full-scale facilities has proved to be...

Two-Color Laser Induced Fluorescence Imaging of Fluid Temperature for Free Convection and Vapor Condensation

Creator:: McAfee, Rachel
Abstract:: The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-color laser induced fluorescence (LIF) provides a non-invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they allow...

The Use of Fractal-Like Bifurcating Flow Channels for Biological Targeted Cooling

Creator:: Stottlemyre, Wyatt
Abstract:: In the wake of climate change, the risk of heat related illnesses has continuously increased over the past several decades. While thermal management solutions have continued to improve, there is a need for efficient cooling systems that conform with the human body. This study combines the solutions from fractal-like flow...
