Transport of helium and fission product gases in porous/fractured geometry
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Measuring and quantifying the transport of helium and fission products in reactor materials is a critical element in the future success of Very High ...
Modeling and analysis of a portable, solid-state neutron detection system for spectroscopic applications
(University of Missouri--Columbia, 2012)
This paper discusses a new neutron detection system that allows local volumetric identification of fast neutron thermalization in the context of forming a solid state Bonner-like neutron spectrometer. The resulting departure ...
State-based simulations of tumor response to radiotherapy
(University of Missouri--Columbia, 2012)
A tumor is comprised of biologically different subdivisions and microenvironmental factors affect the treatment response to radiation therapy (RT). In this work, a state-based tumor response model was developed based on ...
Theoretical and experimental investigations in characterizing and developing multiplexed diamond-based neutron spectrometers
(University of Missouri--Columbia, 2012)
In this work a novel technique of multiplexing diamond is presented where electronic grade diamond plates are connected electrically in series and in parallel to increase the overall detection efficiency of diamond-based ...
Novel techniques towards improving helical tomotherapy delivery and quality assurance
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] TomoTherapy (TomoTherapy, Inc., Madison, WI), an Image-Guided Intensity Modulated Radiation Therapy (IG-IMRT) modality, has been used to treat a variety ...
PIDEC[alpha] : photon intermediate direct energy conversion using the alpha emitter polonium-210
(University of Missouri--Columbia, 2012)
This work details the development of two proof-of-concept Photon Intermediate Direct Energy Conversion systems using the α-emitter Po-210 (PIDECα). Ch. I begins with a short history of nuclear battery development and then ...
Solutions of some transport problems in molecular and phonon transport
(University of Missouri--Columbia, 2012)
Nuclear reactor fuel undergoes vast changes during its lifetime. The fuel generates heat energy while simultaneously suffering neutron bombardments and swelling/rupture due to fission product/gas migration, aggregation and ...
Photon intermediate direct energy conversion using a Sr-90 beta source
(University of Missouri--Columbia, 2012)
This thesis covers an examination of a need for a compact, long lived power source and a proof of concept for one such design. To begin, tests were done dealing with photovoltaics and their lifetime while undergoing radiation ...
Direct simulation Monte Carlo study of phonon heat conduction in solid nuclear fuels
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Heat transfer in solid nonmetallic thin films can be best described by the phonon Boltzmann transport equation (BTE). In this study, the direct simulation ...
Direct simulation Monte Carlo exploration of charge effects on aerosol evolution
(University of Missouri--Columbia, 2012)
Aerosols are potentially generated both during normal operations in a gas cooled Generation IV nuclear reactor and in all nuclear reactors during accident scenarios. These aerosols can become charged due to aerosol generation ...
Modification of materials for high oxidation resistance
(University of Missouri--Columbia, 2012)
As a result of high oil prices and the increase effects of greenhouse gases due to the combustion of fossil fuels is necessary to find other sources of energy. Hydrogen has the potential to replace part of the fossil fuel ...
Development of instrumentation and techniques for preclinical image guided microirradiation
(University of Missouri--Columbia, 2012)
Radiation therapy accounts for more than half of cancer treatments in the US, and in order to provide the most effective treatment to patients, new developments are implemented each year. Before a novel radiation therapy ...
Quantification of absorbed doses from radioactive gold nanoparticles and chromium 51 seed implants
(University of Missouri--Columbia, 2012)
In the ever ending search to seek better options of treatments in radiation therapy, few novel approaches are presented in this thesis. The work presented is in 2 folds. Potentially both can be applied in radiation dose ...
Volumetric modulated arc therapy (VMAT) : advanced delivery techniques for static and moving targets
(University of Missouri--Columbia, 2012)
Volumetric Modulated Arc Therapy (VMAT) is a rotational radiation therapy which has been used to treat various cancer sites. The continuous delivery of a specific treatment plan for arc therapy can be achieved with multiple ...
