Evaluation of ²³⁵U and ²³⁸U Fast Fission Product Yields from Godiva-IV Burst Irradiation via Gamma Detection

Creator:: Tamashiro, Aaron S.
Abstract:: During the past few decades, the U.S. Department of Energy (DOE) has made significant investments to improve nuclear data libraries, as the quality of this data impacts nearly all analyses of nuclear systems. Nuclear fission product yields are one component of these libraries, and are important for the analysis of...

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...

MCNP 6 Simulations of Short-Lived, Low-Yield Fission Byproducts, Gamma-Ray Spectrometry, and their Comparison to Natural Uranium Measurements for the Evaluation of Available Evaluated Nuclear Data Files

Creator:: Jeffries, Tanner D.
Abstract:: Natural uranium samples were irradiated in-core for 7 seconds using the pneumatic rabbit system within the TRIGA Mark II Reactor at Oregon State University, and then used to generate a gamma-ray spectrum with a high purity germanium (HPGe) detector. The irradiated sample was simulated in Monte Carlo N-Particle (MCNP), a...

Impacts of prompt radiation on nuclear blast waves

Creator:: VandenRaadt, Cody
Abstract:: Prompt radiation accounts for 3% of the energy released in a nuclear blast. Simulating the prompt radiation will help identify the potential changes to the ambient temperature and pressure of air around the blast. The changes in ambient conditions may alter blast wave effects. The relationship between the energy deposition...

Characterization of Soft Robotic Materials in Radiation Environments for Nuclear Industry Applications

Creator:: Holley, Logan
Abstract:: Recent advances in robotics have led to interest in exploring soft robotic technologies as an engineering control for reducing the risk of radiation exposure for workers in the nuclear industry. These emerging “soft” technologies offer many advantages over traditional rigid robotic systems and can perform a wide range of tasks...

Predicting Thermal Conductivity in Nuclear Fuels using Rattlesnake-Based Deterministic Phonon Transport Simulations

Creator:: Harter, Jackson R.
Abstract:: The Boltzmann transport equation derived in the Self-Adjoint Angular Flux (SAAF) formulation is applied to simulate phonon transport. The neutron transport code Rattlesnake is leveraged in this fashion, slightly modi ed to accept input from variables consistent with phonon transport simulations. Several benchmark problems are modeled to assess the potential...

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...

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...

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...
