Comparative assessment of small modular reactor Passive Safety System design via integration of dynamic methods of analyses
(2019-12-01)Integral Pressurized Water Reactor (iPWR) type SMR designs were studied featuring Passive Safety Systems (PSS) in all cases. As many as 11 current SMR designs use PSS to remove decay heat. Variations in PSS designs were ... -
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 ... -
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 ... -
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. ... -
An investigation of early radiation damage in exposed eye-lenses of rainbow trout
(2019-08-01)The objective of this work is to contribute to the study of radiation effects in non-human biota and potentially to the study of eye-lens damage in humans by investigating the effects of low-energy X-rays on the lenses of ... -
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 ... -
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 ... -
A Computational Fluid Dynamics based model that predicts wall shear stress in CANDU outlet feeder pipes
(2018-01-01)Wall thinning of carbon steel in CANDU reactor outlet feeder pipes due to Flow Accelerated Corrosion (FAC) is identified as one of the challenges for CANDU reactors since it would force them to shut down due to safety ... -
