Local dose coefficients for radionuclide contamination in wounds
(2020-05-01)The objective of this research is to create local dose coefficients for radionuclide contaminated wounds to accompany dose coefficients obtained by Oak Ridge Institute for Science and Education looking at whole body effects ... -
Low energy photon mimic of the tritium beta decay energy spectrum
(2013-04-01)Tritium is a radioactive hydrogen isotope that is typically produced via neutron interaction with heavy water (D2O), producing tritiated water (DTO). As a result of this, tritium accounts for roughly a third of all ... -
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 ... -
Moderator displacers for reducing coolant void reactivity in CANDU reactors: a neutronics scoping study.
(2014-08-01)When the coolant is voided in a CANDU lattice, the net reactivity change is positive, due primarily to the fact that the coolant and moderator are separated and the coolant volume is much smaller than the moderator volume. ... -
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 ... -
Neutron production in a spherical phantom aboard the international space station
(2010-12-01)Since the beginning of space exploration in last century, several kinds of devices from passive and active dosimeters to radiation environment monitors have been used to measure radiation levels onboard different space ... -
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 ... -
One-dimensional single phase natural circulation model of FLiNaK in Molten Salt Loop
(2019-04-01)This work studied a coolant for a molten salt type reactor in terms of a natural circulation behavior. A natural circulation model using MATLAB was developed. This model is for the Molten Salt Loop currently under development ... -
Optimization of a GEM-based detector to measure tritium and discriminate against other radiation types
(2019-11-01)Tritium poses a radioprotection issue, in the Canadian Nuclear industry due to the operation of its fleet of Canadian Deuterium Uranium (CANDU) heavy water reactors. Although it is a less penetrative radionuclide, tritium ... -
Optimization of plastic scintillator thicknesses for online beta detection in mixed fields
(2010-12-01)For efficient beta detection in a mixed beta gamma field, Monte Carlo simulation models have been built to optimize the thickness of a plastic scintillator, used in whole body monitor. The simulation has been performed ... -
Petri net modeling of fault analysis for probabilistic risk assessment
(2013-04-01)Fault trees and event trees have been widely accepted as the modeling strategy to perform Probabilistic Risk Assessment (PRA). However, there are several limitations associated with fault tree/event tree modeling. These ... -
Planning and optimization of nuclear-renewable micro hybrid energy systems for off-grid applications
(2020-11-01)Resilient operation of medium/large scale off-grid energy systems is a key challenge for energy crisis solutions, which requires continuous and sustainable energy resources. In this context, microreactors are incorporated ... -
Polarization, passivation, intercalation, and generation: an examination of In-Situ and Ex-Situ analytical techniques for the study of carbon anode materials for the electrochemical generation of elemental fluorine.
(2011-12-01)The field of industrial fluorine generation has not made significant progress in the past 60 years due to the difficulty and hazards surrounding the use of hydrofluoric acid (HF) and fluorine gas. This work examines various ... -
Retrospective assessment of human exposures to low dose ionizing radiation using Electron Paramagnetic Resonance (EPR) dosimetry with tooth enamel
