A Deterministic Photon and Electron Dosimetry Model for the Lens of the Eye

Creator:: Boozer, David L.
Abstract:: The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...

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...

Design and analysis of a nuclear reactor core for innovative small light water reactors

Creator:: Soldatov, Alexey I.
Abstract:: In order to address the energy needs of developing countries and remote communities, Oregon State University has proposed the Multi-Application Small Light Water Reactor (MASLWR) design. In order to achieve five years of operation without refueling, use of 8% enriched fuel is necessary. This dissertation is focused on core design...

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...

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...

Measurement and analysis of soft error vulnerability of low-voltage logic and memory circuits

Creator:: Pawlowski, Robert
Abstract:: Scaling the supply voltage into the sub/near-threshold domain is one of the most effective methods for improving the energy efficiency of next-generation electronic microsystems. Unfortunately, the relationship between low-voltage operation and radiation-induced soft error rate is not widely known, as little research has been previously performed and reported for soft-error...

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...

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...

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...
