Progress in the development of a portable phoswich-style skin contamination dosimeter

Creator:: Tang, Matthew M.
Abstract:: The Code of Federal Regulations (10CFR20.1201) mandates occupational dose limits to the shallow, lens and deep tissue layers. The NRC-accepted procedure of estimating dose to these layers from contamination events is laborious. The current work aims to further the development of a portable phoswich-style skin dosimeter that will operate in...

Design, construction, and analysis of a skin contamination dosimeter

Creator:: Cazalas, Edward J.
Abstract:: International recommendations provided by the International Commission on Radiation Protection (ICRP), as well as national regulations, set by the U.S. Nuclear Regulatory Commission (NRC), state that the exposure of skin to highly concentrated radioactive sources should be monitored at specified depths in skin and kept below specific dose equivalence levels....

Comparison of object detection and image quality between conventional digital mammography and digital breast tomosynthesis through contrast measurements and phantom image evaluation

Creator:: Leek, Angela E.
Abstract:: Advancements in digital detector technology over the past decade have facilitated the transition of mammography image acquisition from film screen to full field digital applications. Nearly 90% of the mammography performed in the United States utilizes digital imaging technologies. The ability to capture the image information in an electronic format...

Synthesis and testing of a novel soft donor organic extractant molecule for targeted soft metal extraction from aqueous phases

Creator:: Gullekson, Brian J.
Abstract:: Spent nuclear fuel (SNF) resultant from the generation of nuclear power is a chemically and radiologically diverse system which is advantageous to chemically process prior to geologic disposal. Hydrometallurgy is the primary technology for chemical processing for light water reactor spent fuels, where spent fuel is dissolved in an acid...

Steady-State Computational Fluid Dynamics Analysis of a Quarter-Core Liquid Metal-hydride Cooled Microreactor

Creator:: Stevens, Kaeley R.
Abstract:: This thesis assessed the passive, natural circulation, design for a Bi-Ca-CaH2 cooled microreactor based on initial figures of merit. The values for the figures of merit selected for this thesis were: the maximum temperature in the core should not be more than 150 K above the average core outlet temperature,...

Analysis of the method of tubes characteristic schemes in the thick diffusive limit

Creator:: Rising, Michael E.
Abstract:: Characteristic methods are widely known to be very accurate approaches to the solution of numerical transport problems. These methods are most often used for neutron transport applications (i.e. lattice physics calculations) where spatial cells are of intermediate optical thickness (O(1) - O(100) mean free paths, depending on the energy group)...

Generation of Multigroup Multiband Cross Sections with Monte Carlo Simulations

Creator:: Lam, Adam Q.
Abstract:: This is the investigation into The generation of high-fidelity multigroup multiband cross sections from Monte Carlo neutron transport simulations. Previous methods for generating multigroup multiband (MGMB) cross sections, and multigroup cross sections, assume an approximate shape for the scalar flux. This approximate flux shape is the product of an energy-dependent...

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...

Vibration Analysis of Advanced Test Reactor Miniplate Hydraulic Test in the OSU HMFTF

Creator:: Latimer, Griffen D.
Abstract:: Current research on the topic of advanced reactor fuel types include the use of ultrahigh density Uranium-Molybdenum fuels, towards their use in high-performance research reactors. These reactors operate with high power densities, and the increased cooling requirements therefore place high relevance on the fluid-structure interaction with these fuel elements; therefore...

An assessment of a mesh-based method for slab-geometry transport in stochastic materials

Creator:: Bassett, Brody R.
Abstract:: There exists a variety of methods to solve the radiation transport equation in stochastic materials, including the Levermore-Pomraning method and the atomic mix method, each of which is designed to replicate the results given by benchmarks with materials rearranged in a randomized fashion. While the atomic mix method is very...
