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 ...
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 ...
The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
(2010-04-01)
Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. ...
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 ...
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 ...
Conceptual design of a thermal hydraulic loop for multiple test geometries at supercritical conditions named supercritical phenomena experimental test apparatus (SPETA)
(2012-04-01)
The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. ...
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. ...
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 ...
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 ...
