Analysis of the potential for flow-induced deflection of nuclear reactor fuel plates under high velocity flows
(University of Missouri--Columbia, 2015)
The University of Missouri Research Reactor (MURR) is one of five High Performance Research Reactors(HPRRs) in the U.S. that still utilizes high enriched uranium (HEU) fuel. Currently, a novel LEU fuel is under consideration ...
Development and experimental benchmarking of numeric fluid structure interaction models for research reactor fuel analysis
(University of Missouri--Columbia, 2015)
As part of the Global Threat Reduction Initiative (GTRI) reactor conversion program, five U.S. High Performance Research Reactors (HPRRs) are currently studying a novel Low Enriched Uranium (LEU) foil based fuel to replace ...
An experimental investigation of the fluid structure interactions of a single curved nuclear fuel plate in a narrow channel
(University of Missouri--Columbia, 2017)
Nuclear research reactors are major scientific tools used by researchers all over the word to produce medical isotopes, irradiated materials, as well as study nuclear processes. Most fuel for research reactors is in the ...
Numeric modeling of a micro-scale differential thermal calorimeter for the purpose of cryopreservation
(University of Missouri--Columbia, 2017)
Cryopreservation requires biological material to be stored at temperatures well below the freezing point of water. During the process of cryopreservation, the cooling rate should be carefully chosen to avoid cell damage ...
Analysis of resonant ultrasound spectroscopy as a technique to evaluate material property changes
(University of Missouri--Columbia, 2017)
The objective of this thesis is to validate Resonant Ultrasound Spectroscopy (RUS) as a non-destructive evaluation tool that can be used to study effects of radiation on the mechanical properties of a material, mainly its ...
Fabrication and testing of a tool for thermodynamic characterization of micro-samples
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cryopreservation utilizes very low temperatures to preserve living cells and tissues. Successfully cryopreservation protocols for a limited number of ...
Lifetime analysis of irradiated beryllium in research reactors /
(University of Missouri--Columbia, 2017)
The objective of this study is to develop a technique to predict onset of cracking and ultimately failure of materials exposed to neutronic bombardment. Beryllium is commonly used in research reactors as a reflector material ...
A parametric study of a curved nuclear fuel plate in a narrow channel using numeric fluid structure interaction modeling
(University of Missouri--Columbia, 2017)
In 2004 the Global Threat Reduction Initiative (GTRI) was established by the National Nuclear Security Administration (NNSA) to quickly identify, secure, remove and/or closely monitor nuclear and radiological materials ...
Thermal-mechanical analysis of a low-enriched uranium foil based annular target for the production of molybdenum-99
(University of Missouri--Columbia, 2011)
One of the US department of Energy's global threat reduction initiative goals is to eliminate the use of high-enriched uranium from the production of the radio-isotope Molybdenum-99. One strategy to achieve this goal is ...
The thermal-mechanical analysis of targets for the high volume production of molybdenum-99 using a low-enriched uranium metal foil
(University of Missouri--Columbia, 2012)
Molybdenum-99 diagnostic imaging is the most commonly practiced procedure in nuclear medicine today with the majority molybdenum-99 produced with proliferation sensitive HEU. International and domestic efforts to develop ...
Microfabrication and modeling of a tool for thermodynamic characterization of micro-samples
(University of Missouri--Columbia, 2012)
Cryopreservation is the process of preserving biological samples indefinitely at subzero temperatures. Successful cooling procedures have been developed for a limited number of cell types through an extensive amount of ...
Electron emission thermal energy conversion
(University of Missouri--Columbia, 2010)
Electron emission from a surface can be achieved via two mechanisms: tunneling and thermionics. Converting thermal energy to electrical power using these mechanisms is achieved by generation of an electron current from the ...

Thermal mehcanical hydraulic experimental tools for molybdenum-99 production target analysis
(University of Missouri--Columbia, 2013)
As the nuclear community adapts to meet a constantly changing environment driven by policy development, so must the technology associated; in particular is the case of technology qualification. While government institutions ...
Evaluation of using ferrofluid as an interface material for a field-reversible thermal connector
(University of Missouri--Columbia, 2013)
The electrical functionality of an avionics chassis is limited due to heat dissipation limits. The limits arise due to the fact that components in an avionic computer boxes are packed very compactly, with the components ...
