Developing a framework for thermodynamic measurements of fluoride salt nuclear fuel
(2019-10-01)
With a single liquid acting simultaneously as a primary coolant and a nuclear fuel, molten salt reactor development has been challenged with understanding the behavior of its complex fluoride solution under various conditions. ...
Study of contaminants in plasmas during decommissioning processes
(2020-12-01)
With the intention of eventual development of on-site radionuclide capture technologies, methods to simulate radionuclide behaviour when contaminated components are subjected to plasma-based decommissioning processes are ...
Towards low dose retrospective dosimetry on shelled species
(2020-08-01)
This work investigates calcified tissues of shelled species for retrospective dosimetry using electron paramagnetic resonance (EPR) spectroscopy. To determine applicable samples for low dose studies, shells of crustacean ...
Simulation of in-core dose rates for an offline CANDU reactor
(2016-04-01)
This thesis describes the development of a Monte Carlo simulation to predict the dose rates that will be encountered by a novel robotic inspection system for the pressure tubes of an offline CANDU reactor. Simulations were ...
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 ...
Examination of secondary electrons generated by encapsulated gamma sources to improve contact dosimetry estimates
(2017-04-01)
Secondary electron generation on the surface of encapsulated gamma sources can play a large role in the dose measured near the surface of the encapsulation. The National Council on Radiation Protection and Measurements ...
Characterization of neutron fields around an intense neutron generator
(2016-12-01)
Neutron fields in the vicinity of the University of Ontario Institute of Technology neutron facility have been investigated in a series of simulations and experiments. The neutron fluence at several locations around the ...
A generic methodology for the three dimensional display of radiation fields
(2010-04-01)
The radiation field visualization options available for engineers, scientists and health physicists have traditionally been based in the 2d realm, with techniques such as the generation of isodose curves. From the perspective ...
Investigation of sub-cell homogenization for PHWR lattice cells using superhomogenization factors
(2016-12-01)
To avoid the computational effort associated with full-core neutron transport calculations, full-core neutronics calculations for Pressurized Heavy-Water Reactors (PHWRs) are usually performed in diffusion theory using an ...
Dynamic accident sequence analysis using dynamic flowgraph method and Markov/cell-to-cell mapping technique
(2018-07-01)
In the recent years, numerous concerns have been raised regarding the capabilities and adequacy of classical probabilistic safety assessment (PSA) techniques (fault/event tree) to account for dynamic system interactions ...
