Application of Spectroscopic Techniques for In-Situ Oxygen Monitoring in Liquid Sodium

Creator:: Walton, Seth L.
Abstract:: In liquid sodium environments like those proposed for next-generation sodium fast reactors (SFRs), the presence of impurities in the sodium, particularly chemical species containing oxygen, can lead to increased corrosion on sodium-wetted components. It is important to monitor oxygen concentration in the sodium melt, but temperatures of 500 ℃ and...

Benchmark comparison of the Oregon State TRIGA reactor between MCNP6 and Serpent 2

Creator:: Law, Tyler
Abstract:: A model of the Oregon State TRIGA reactor was developed in Serpent 2 by translating a previously accepted MCNP model. Both models were verified and validated via comparison of each model and data gathered from the core start-up. Reactivity bias in each code was determined. Using the rod drop method,...

CFD Verification, Validation, and Sensitivity Study of Internally Heated Concentric Tube Thermosyphon O-SERTTA

Creator:: Miller, Jaden
Abstract:: Irradiation experiments are a critical aspect of the nuclear fuels and materials qualification process. Determining the flow conditions of these experiments is necessary for understanding response of nuclear components during transient and normal operation. Quality flow data is lacking for cartridge-type irradiation experiments with annular flow natural circulation designs. Data...

Thermal Stability of Advanced Metallic Nuclear Fuel Microstructures

Creator:: Wright, Alexander A.
Abstract:: Metallic nuclear fuels have long been studied for use in advanced nuclear reactors, with efforts invested in improving the viability of metallic nuclear fuel elements and overall safety of advanced reactor design concepts. During reactor operations, fuel forms undergo restructuring due to a variety of physical phenomena. Expansion of the...

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...

Quantifying System Distortions between the VTR and IVTR facilities through H2TS Scaling Methodology and RELAP5-3D Simulations

Creator:: Johnson, Juwan A.
Abstract:: Sodium Cooled Fast Reactors (SFR) are complex and expensive due to high operating temperatures and neutron flux which pose technical challenges for these reactors. To overcome these challenges with SFRs, research and development of small scale and large-scale facilities are needed to bridge the gap in understanding. Scaling analyses develop...

Identifying the Effects of Combustion Products, Turbulent Fluctuations, and Delivered Energy on Ignition Characteristics of Forced Ignition of Jet-A/air Mixtures

Creator:: Teope, Kaz I.
Abstract:: The operation of gas turbine engines depends on the reliable ignition of fuel/air mixtures. Gas turbine engines are commonly used as commercial and military aviation power plants. However, consistent ignition within gas turbine engines is still a problem, especially for more challenging operating conditions such as emergency operations. This work...

High Fidelity 3-Omega Probe Installation and Verification in a Scanning Electron Microscope

Creator:: Powers, Robert D.
Abstract:: There are efforts underway at Idaho National Laboratory to design, modify, and implement an array of techniques into a nuclear material ready Scanning Electron Microscope (SEM) to accelerate comprehensive characterization of the physical properties and microstructures of irradiated fuels and materials. The goals of adding a micro four-point probe (M4PP)...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...
