The influence of surface tension on F2-Bubble Morphology at detachment from carbon electrodes in KF-2HF molten fluoride salt
(2020-04-01)Molecular F2 and H2-bubbles were generated electrochemically on amorphous carbon electrodes in KF-2HF molten salt to study the effect of surface tension (ϒ) on the profile of a bubble. F2 is used for the purification and ... -
Investigation of the bubble detector response to high LET space radiation
(2018-08-01)The radiation environment aboard spacecraft is a complex mixture of neutrons, photons, protons, heavy ions and other particles. A special type of superheated droplet detectors referred to as space bubble detectors (SBD) ... -
Methods for optimization of neutron detector performance in nuclear power plants
(2018-08-01)Safety of nuclear power plants (NPPs) requires shutdown systems to mitigate design-basis accidents. Shutdown is based on measurements from in-core flux detectors. Thus, this thesis proposes a methodology for managing ... -
A new approach to neutron spectrometry with multi-element scintillators
(2014-02-01)The combined effects of the nuclear industrial renaissance, the events of 9/11, and the Fukushima disaster have had a significant impact on the research and development of radiation detection instrumentation. Notably, there ... -
New approaches in training for in situ visualization of ionizing radiation measurements
(2022-08-01)Surveying an environment for sources of ionizing radiation requires the use of measurement tools and skills developed from training in order to understand and analyze measurements. Recent advances in technology allow for ... -
Retrospective assessment of human exposures to low dose ionizing radiation using Electron Paramagnetic Resonance (EPR) dosimetry with tooth enamel
(2022-04-01)This study collected the extracted teeth from people of different ages in the Durham region and analyzed them using the X-band CW EPR spectroscopy. The total dose rate from the natural and anthropogenic sources was 1.9721 ... -
Specifics of forced-convective heat transfer to supercritical CO2 flowing upward in vertical bare tubes
(2015-04-01)Heat transfer in the forced convection regime of fluids at supercritical conditions has been studied extensively for the past 60 years. The dominant approach to summarize the experimental results was by proposing empirical ... -
Study on specifics of thermalhydraulics and neutronics of pressure-channel supercritical water-cooled reactors (SCWRs)
(2017-08-01)A group of countries has initiated an international collaboration to develop a next generation (i.e., Generation IV) of nuclear reactors. Chosen as one of the six Generation‒IV nuclear-reactor concepts, the SCWRs are ...
