Development and optimization of new generation start-up instrumentation systems (SUI) for domestic CANDU reactors
(2010-12-01)
Due to the age and operating experience of Bruce Power units, equipment ageing and obsolescence has become one of the main challenges that need to be resolved for all systems, structures and components in order to ensure ...
Thermal aspects of high efficiency channel with conventional and alternative fuels in SuperCritical water-cooled reactor (SCWR) applications
(2011-03-01)
Chosen as one of six Generation‒IV nuclear-reactor concepts, SuperCritical Water-cooled Reactors (SCWRs) are expected to have high thermal efficiencies within the range of 45 ‒ 50% owing to reactor‘s high outlet temperatures. ...
Determining the effectiveness of nuclear security through computer simulation
(2015-09-01)
There is a growing concern from both national regulators and the International
Atomic Energy Agency (IAEA) about the threat posed by attacks against iconic targets such as nuclear power plants. This has led to an increased ...
Developing 1-D heat transfer correlations for supercritical water and carbon dioxide in vertical tubes
(2014-03-01)
Taking into account the expected increase in global energy demands and increasing climate change issues, there is a pressing need to develop new environmentally sustainable energy systems. Nuclear energy will play a major ...
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 ...
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 ...
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 ...
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 ...
