Transmutation rates in the annulus gas of pressure tube water reactors
(2011-07-01)
CANDU (CANada Deuterium Uranium) reactor utilizes Pressure Tube (PT) fuel channel design and heavy water as a coolant. Fuel channel annulus gas acts as an insulator to minimize heat losses from the coolant to the moderator. ...
Dosimetric characterization of a miniature x-ray source for biophysics studies
(2015-07-01)
Tritium is a low energy beta emitter that is found in abundance at CANDU nuclear power plants and is a cause of concern since it accounts for roughly thirty three percent of the total occupational exposure of nuclear ...
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 ...
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. ...
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 ...
Implementation of power electronics in nuclear power plants: DC electrical system conceptual design and its financial analysis
(2018-05-01)
A Power Electronic (PE) device is a semiconductor-based device which enable many advanced conversion of electricity which have been used widely in many industries. Due to the recent development in both circuit design and ...
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 ...
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 ...
Characterization of PVA-Borax-fructose gel for the capture of radioactive wastes generated during nuclear decommissioning activities
(2021-05-01)
With the long-term objective of using polymer gels for the capture of solid, liquid and gaseous waste generated from decommissioning works, characterization of gel properties as well as the properties of the individual ...
Experimental investigations of thermodynamic properties of the LiF –CsF binary system and FliNaK
(2020-07-01)
Generation IV nuclear power technologies, including various molten salt reactor designs are considered to accommodate growing energy needs with minimal impact on the environment. The development of the molten salt reactor ...
