A Rapid β-/γ Autoradiographic Imaging Method for Post-detonation Nuclear Forensics and Radiological Emergency Response

Creator:: Foley, Ari A. R.
Abstract:: In a radiological emergency scenario, the capability to rapidly visualize radiation emitted from debris, contamination, or absorbed in biological samples, while visualizing the non-radioactive (or “conventional” image) features within a ﬁeld of view, will provide critical information to support optimization of further analysis, sample collection, and decision making. This research...

Dosimetric Evaluation of Nasal Cavity Basal Cell Layer during Radiotracer Administration

Creator:: Flora, Rigel
Abstract:: New delivery methods for radiotracers are constantly being proposed. Two key properties of the delivery method must be analyzed: dose to patient and effectiveness of delivery. In this work, the localized skin dose for intranasal administration of 18F was determined utilizing MCNP code. An anatomically accurate nasal cavity was constructed...

Flat Plate Free Convective Heat Transfer

Creator:: Bristol, Benjanmin R.
Abstract:: The OSU MASLWR Test facility is a scaled integral systems LOCA and proof-of-concept test facility for the Multi-Application Small Light Water Reactor design concept. A unique feature of this design is to utilize a small high pressure containment vessel to provide the safety containment function for an integral reactor pressure...

Nitrogen concentration sensitivity study of the lock exchange phenomenon in the high temperature test facility

Creator:: Utberg, John E., Jr
Abstract:: The Modular High Temperature Gas-Cooled Reactor (MHTGR) is a graphite moderated reactor that utilizes helium as its coolant. One consideration of importance is how the MHTGR will perform during a Depressurized Conduction Cooldown (DCC) accident, which generally can be divided into three phases: depressurization, air ingress, and natural circulation. After...

Reactor physics model of the Advanced Test Reactor using TRIGA® fuel through application of Serpent 2

Creator:: Lyons, Jennifer
Abstract:: The Advanced Test Reactor (ATR), under the Reduced Enrichment for Research and Test Reactors (RERTR) Program and the Global Threat Reduction Initiative (GTRI), is conducting feasibility studies for the conversion of its fuel from a highly enriched uranium (HEU) composition to a low enriched uranium (LEU) composition. These studies have...

Dissolution of uranium dioxide microspheres in carbonate and hydrogen peroxide solutions

Creator:: Adams, Timothy G.
Abstract:: Uranium dioxide has been used in industry both as a fuel for power reactors and as a target for the production of radioisotopes. One of the most important radioisotopes produced using these targets is molybdenum-99 (Mo-99, 65.94hr half-life), which is the parent isotope to technetium-99m (Tc-99m, 6.01hr half-life), a radioisotope...

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...

Phase distribution parameter determination by neutron radiography

Creator:: Skinner, Jesse B.
Abstract:: A phase distribution parameter has been added to the one-dimensional two-phase horizontal flow conservation equations. The phase distribution parameter was incorporated into the conservation equations in an attempt to add stability and remove correlation switching by incorporating gravity. Determination of the phase distribution parameter requires an average void fraction profile...
Resource Type:: Masters Thesis

On the effects of centrifugal forces in air-water two-phase flow regime transitions of an adiabatic helical geometry

Creator:: Young, Eric P.
Abstract:: Two-phase flow in helical conduits is important in many industries where reaction between components, heat transfer, and mass transport are utilized as processes. The helical design is chosen for the effects of secondary flow patterns that reduce axial dispersion, increased heat transfer, and also their compact design. The first is...

Peak reconstruction of single particle mass spectrometry transient signals to recapture ion count and improve SNM ratio measurements

Creator:: Mannino, Mitchell
Abstract:: Quick and accurate measurements of nanoparticles have important applications in biology, environmental and non-proliferation areas. Calculation of isotopic ratios, particularly in special nuclear materials, has relied on integration of nanoparticle counts and limited the capability of counting minor isotopes. Rapid transient detection method of nanoparticles has demonstrated the effectiveness of...
