Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...

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...

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...

Modeling the Fusion Reaction in an Inertial Electrostatic Confinement Reactor with the Particle-in-Cell Method

Creator:: van de Lindt, Jacob
Abstract:: Nuclear fusion has the potential to meet the energy needs of our civilization for centuries to come and does not produce harmful greenhouse gasses or produce long-lasting radioactive waste. A fusion reaction can be readily demonstrated in a confinement scheme known as inertial electrostatic confinement (IEC) fusion. In this work,...

Thermal hydraulic analysis of the Oregon State TRIGA Reactor using RELAP5-3D

Creator:: Marcum, Wade R.
Abstract:: Oregon State University has recently conducted a complete core conversion analysis as part of the Reduced Enrichment for Research and Test Reactors Pprogram. The goals of the thermal hydraulic analyses were to calculate natural circulation flow rates, coolant temperatures and fuel temperatures as a function of core power for both...

Problems of Shape and Information in Multiscale Modeling of Transport Phenomena

Creator:: Ostvar, Sassan
Abstract:: This work is a compilation of problems that deal with multiscale analysis of transport phenomena in environmental systems. A common feature among the problems studied here is the presence of non-negligible microscale structure in various forms. Each problem is approached from the perspective that a macroscopic observable encodes aspects of...

Predicting mechanical instability of a cylindrical plate under axial flow conditions

Creator:: Marcum, Wade R.
Abstract:: Five U.S. high performance research reactors (HPRRs) are currently part of an international nonproliferation program with the objective of ultimately converting their highly enriched uranium (HEU) fuel to a new high density, low enriched uranium (LEU) fuel while still maintaining their reactor kinetic and thermal hydraulic performance. A uranium-molybdenum (U-Mo)...

Tabletop fusion reactors : construction and testing of a demonstration inertial electrostatic confinement fusor

Creator:: Holler, Logan R.
Abstract:: Nuclear fusion reactors comprise a significant field of study due to their potential to provide a limitless, clean, and sustainable source of energy. The inertial electrostatic confinement fusor is a type of fusion-generating device that accelerates deuterium gas to the conditions required for fusion. The goal of this research was...

Experimental and theoretical analysis of radial porosity in a monodisperse sphere packing

Creator:: Nakamoto, Nathan
Abstract:: This thesis presents an experimental study of radial porosity in a manually filled cylindrical container with glass spheres. The symmetric distribution of bead diameter allowed for normalization of container properties and porosity models. The aspect ratio of the container was approximately 3.9, with tube-to-particle-diameter ratio λ ≈ 24.6 and height-to-particle-diameter...
