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 ...
CFD determination of fluid and geometry related localized heat transfer phenomena for supercritical water flow
(2017-04-01)
The proposed concept of Supercritical Water-cooled Reactor (SCWR) as part of the Generation IV International Forum aims to improve the thermal efficiency over current power plants by utilizing cooling water at pressures ...
Special isotopes of the FUGEN nuclear reactor
(2022-04-01)
The Canadian and Japanese nuclear regulatory bodies have shown dissimilarities between the isotopes considered to be of interest in decommissioning similarly styled heavy water reactors. This research examines the quantity ...
Development of neutron monitor for fusion systems
(2022-04-01)
Currently, the detection of neutrons employs sensors with a high thermal neutron response embedded in a thermalizing medium. However, this approach does not provide much information on neutron energy and, therefore, is ...
Using MELCOR with enhanced predictive capabilities via Thermochimica to model two severe accident cases of a generic BWR with Zry-2 and FeCrAl
(2022-07-01)
The primary goal of this work was to enhance MELCOR’s material modelling capabilities via one-way coupling of Thermochimica. MELCOR is a state-of-the-art code used to simulate the severe accident progression of a nuclear ...
A benchmarked dynamic model of xenon behavior in a molten salt reactor
(2019-12-01)
Molten salt reactors are a type of nuclear reactor that are being considered for deployment in the fourth generation nuclear power technology. Molten salt reactors use molten a alkali / actinide halide salt melt at ...
The conceptualization and parameterization of a gaseous detector rasterizing pinhole gamma camera
(2016-08-01)
This thesis details the conceptualization and parameterization of a gaseous detector rasterizing pinhole gamma camera. In this thesis, there is a literature review that describes the historical development of gamma imaging, ...
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 ...
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 ...
Study of LaBr3 (Ce) detector response to high energy helium ions
(University of Ontario Institute of Technology, 2022-04-01)
The space radiation environment is a complex mixed field composed of neutral and charged particles such as photons, protons, alpha, and other particles. The mixture of these different particles creates a challenge in any ...
