Measurement of 239Pu, 237Np, and 238U Fission Product γ Rays

Creator:: Tamashiro, Aaron S.
Abstract:: Fission product yields (FPYs) are used for a wide range of applications including nuclear fission theory, nuclear reactor design, reactor antineutrino anomaly, stellar nucleosynthesis, and nuclear forensics. These applications rely on FPYs that were last evaluated in 1993, which included measurements from all over the world up until 1993. In...

Characterization of Radionuclide Resuspension via Aeolian Processes at the Ambrosia Lake West Mill Facility

Creator:: Adriatico, Vanessa L.
Abstract:: The Ambrosia Lake West Site is a former uranium recovery facility located north of Grants, New Mexico. It currently serves as a uranium mill tailings site undergoing reclamation and decommissioning. High velocity winds are common in the area, causing soil erosion via aeolian processes. Strong winds may carry soil for...
Resource Type:: Masters Thesis

Inter-code Comparison of Time Independent Pulsed Sphere Benchmark Results

Creator:: Northrop, Jordan
Abstract:: The pulsed sphere benchmark problems are a set of physical experiments that have been used to verify Monte Carlo codes and evaluate nuclear data. All Monte Carlo codes rely on benchmark experiments that test the features of the code to verify that the simulations are producing realistic results. In the...

Effects of MCNP Model Resolution on Predicting Water Equivalent Thickness of Nanocomposite Materials in High-Energy Proton Fields

Creator:: Freilich, Justina A. M.
Abstract:: Manned missions beyond low-Earth orbit present tremendous, multifaceted radiological challenges. The deep space radiation environment contains high-energy protons and heavy ions, which are not sufficiently shielded by the aluminum alloys that have historically been used in spacecraft. To address these shielding concerns, polymer-based nanocomposites have been proposed. Radiation transport simulations...

Development of a High-Energy Neutron Sniffer and Subsequence Dose Quantification for High-Energy Particle Accelerator Shielding Surveys

Creator:: Overbay, Lauren A.
Abstract:: The objective of this research is to design a portable neutron detector that is lightweight and responds to neutrons with energies of 20 MeV and greater. The instrument will be used as a ‘sniffer’ probe for identifying shielding weaknesses at high-energy particle accelerators and be paired with a plastic scintillator...

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...

Design of a 3-D Printed Eye Model for Quantification and Analysis of Retinal Image Distortion in the Ophthalmic Plaque Brachytherapy Treatment Planning Process

Creator:: Smith, Lauren D.
Abstract:: Ophthalmic plaque brachytherapy is a form of internal radiation treatment for uveal melanoma, the most common eye cancer in adults. During treatment, a plaque containing radioactive seeds is surgically attached to the sclera, directly adjacent to the ocular tumor site. Plaque Simulator™ is an eye plaque brachytherapy planning software that...

Atmospheric Radon Modeling for Aerial Measurements

Creator:: Owensby, Brittany N.
Abstract:: The Ariel Measuring System (AMS) is a national asset in responding to radiological or nuclear events. The AMS operates out of several aerial platforms, such as the BK-117 helicopter and the P3 Long Range Tracker, under many equipment configurations. Measurements can be telemetered real time to reach back for evaluation...

Feasibility of Enrichment Measurements with a Pixelated CdTe HEXITEC Detector: A Comparison of Methods

Creator:: Kasparek, Dustin
Abstract:: The International Atomic Energy Agency (IAEA) is responsible for verifying the mass of elemental uranium in various forms (powders, pellets, scrap) as part of safeguards inspections at nuclear fuel fabrication facilities in support of the nuclear non-proliferation treaty. Current methods require in-field dissolution chemistry, which is time consuming and imposes...

Soft Robotics in Radiation Environments : A Prospective Study of an Emerging Automated Technology for Existing Nuclear Applications

Creator:: Oshiro, Tyler T.
Abstract:: Traditional robots have a long history in nuclear-related work because their integration decreases risk to humans in dangerous environments. Soft robotics is one promising new branch of traditional robotics with proposed applications in industry, medicine, and society. Collaborators from the Robotics mLab at Oregon State University (OSU) are currently working...
