A Numerical Investigation into Capillary-Wrapped Liquid Sodium Pin-Bundles for Instrumentation Development

Creator:: Vietz, Stefan
Abstract:: Liquid sodium is a challenging fluid to perform verification and validation for. Its chemical reactivity, large thermal conductivity, and opacity make both modeling and experimental data gathering difficult. Converting the wire wraps of liquid sodium reactor fuel pin geometry into capillaries, and inserting fiber optic temperature sensors, promises to capture...

Feasibility Study of a Thermal Spectrum Thorium Breeder Reactor Without Chemical Reprocessing

Creator:: Keppen, Jackson D.
Abstract:: This thesis presents a feasibility study of a thorium fueled thermal spectrum breeder-burner reactor that operates without chemical reprocessing. Materials were evaluated for their potential as moderators using standard analytical methods. These materials were then used as moderators to evaluate criticality and enrichment in an infinite fuel pin lattice. The...

Scaling analysis of the Direct Reactor Auxiliary Cooling System for Gas-cooled Fast Reactors during a Depressurized Loss of Forced Convection Event

Creator:: Blake, Grant C.
Abstract:: The Direct Reactor Auxiliary Cooling System (DRACS) is a passive safety system capable of removing decay heat directly from the reactor core. Its modularity makes it scalable for use in reactors with various power levels. Work has previously been completed to support inclusion of the DRACS in liquid metal reactors...

Capabilities of Detecting Medical Isotope Facilities through Radioxenon Sampling

Creator:: MacDougall, Matthew R.
Abstract:: Medical Isotopes are a necessity in modern medicine for cancer treatments and medical imaging. In order to ensure that the needs and demands are met for the medical procedures, facilities are put in place to produce these isotopes. There are over 25 different isotopes of interest being produced by more...

Proof of concept of the use of RAVEN and RELAP5-3D for risk informed safety margin characterization

Creator:: Riley, Thomas H.
Abstract:: This project was a proof of concept of the use of the RAVEN software, a tool developed for the Risk Informed Safety Margin Characterization (RISMC) approach, with RELAP5-3D. This novel approach combines older probabilistic and mechanistic approaches to look at how and why the complex systems of a nuclear power...

Multi-Scale, Multi-Physics Reactor Pulse Simulation Method with Macroscopic and Microscopic Feedback Effects

Creator:: Zabriskie, Adam X.
Abstract:: The Transient Reactor Test facility (TREAT) at Idaho National Laboratory (INL) is a unique reactor capable of stressing test fuel during a power pulse transient. TREAT fuel is composed of high enriched uranium (HEU) heterogeneous fuel; microscopic UO₂ fuel grains with an average radius of 10 μm are randomly distributed...

Distributed OpenCL : a platform for distributed, heterogeneous computing for domain scientists

Creator:: Dillon, William H.
Abstract:: It is possible to purchase, for as little as $10,000, a cluster of computers with the capability to rival the supercomputers of only a few years ago. Now, users that have little to no experience developing distributed applications or managing a cluster are in a position to do so. To...

Crustal structure of the Queen Charlotte Transform Fault Zone from multichannel seismic reflection and gravity data

Creator:: Scheidhauer, Maren
Abstract:: The Queen Charlotte Fault system is a segment of the North America - Pacific plate boundary. From 45 Ma - 5 Ma, plate motion has been primarily translational. Since 5 Ma, transpression has been the dominant mode of interaction. The plate boundary west of the Queen Charlotte Islands is characterized...

Natural circulation scaling of a pressurized conduction cooldown event in the upper plenum of the modular high temperature gas reactor

Creator:: King, Brian M.
Abstract:: In a Modular High Temperature Gas Reactor (MHGTR), the Pressurized Conduction Cooldown (PCC) event is an accident scenario in which there is a loss of forced convection of the coolant through the system but the pressure boundary remains intact. When the PCC event occurs, natural circulation onsets which results in...

Effect of Initial System Temperature on Initiation of Natural Circulation during a Depressurized Conduction Cooldown Event in the High Temperature Test Facility

Creator:: Brumback, Kyle E.
Abstract:: High Temperature Gas Reactors (HTGR) are a type of power plants that can provide industrial process heat and high efficiency, carbon-free electricity. The High Temperature Test Facility (HTTF) has been designed to provide data that can be used for the validation of system codes and verification of passive safety features...
