Design and construction of a one-dimensional particle tracker for measurement of alpha particle stopping power
(2019-08-01)
The energy deposited by a charged particle in a medium is non-uniform and peaks near the end of the particle’s path. The energy deposition through the medium is known as stopping power and the shape of this function is ...
An experimental study of the relative response of plastic scintillators to photons and beta particles within the context of tritium monitoring
(2011-08-01)
A scintillation counting system has been constructed with the use of BC-400 and EJ-212 series plastic scintillators along with a subminiature photomultiplier tube to investigate the effect of increasing plastic scintillator ...
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
(2015-08-01)
In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ...
Development of a semi-autonomous directional and spectroscopic radiation detection mobile platform
(2014-03-01)
This thesis presents a method for a small, inexpensive mobile robot equipped with a single high resolution scintillation detector to quickly survey an area and convey information about local sources of gamma radiation to ...
Thermal aspects of using alternative nuclear fuels in supercritical water-cooled reactors
(2010-11-01)
A SuperCritical Water-cooled Nuclear Reactor (SCWR) is a Generation IV concept currently being developed worldwide. Unique to this reactor type is the use of light-water coolant above its critical point. The current research ...
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 ...
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 ...
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, ...
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 ...
