Design of a fault tolerant control scheme based on sliding mode for Canadian supercritical water reactor
(2016-08-01)
Canadian Super Critical Water Reactor (SCWR) is one of the Generation IV reactor types and possible heat source for co-hydrogen production through copper chlorine thermochemical cycle. To maintain the balance between the ...
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
(2015-08-01)
In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ...
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 ...
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 energy compensated Geiger Muller detector based on the T2416A Canberra Co. GM detector
(2013-07-08)
Geiger Muller counters have been a fundamental device in radiation detection for decades due to their simplicity and low cost. Canberra Company has been designing and manufacturing Geiger Muller detectors in various designs ...
Simulation of dynamic response of Self-Powered-Inconel-Neutron-Detector lead cables using a semi-empirical model
(2013-11-01)
The work presented here was devoted to the modelling and simulation of the dynamic response of lead cables of Inconel self-powered neutron detectors in a CANDUpower reactor. The main goal was to develop a semi-empirical ...
Encapsulated source contact dose estimates incorporating secondary electron emission
(2015-04-01)
Secondary electron emission generated at the surface of thin material from interaction with gamma rays form a significant component of the surface dose. The intensity of this emission is known to vary with material composition ...
Three dimensional heterogeneous finite element method for static multi-group neutron diffusion
(2010-08-01)
Because current full-core neutronic-calculations use two-group neutron diffusion and rely on homogenizing fuel assemblies, reconstructing pin powers from such a calculation is an elaborate and not very accurate process; ...
The application of experimental microdosimetry to mixed-field neutron-gamma dosimetry
(2012-12-01)
Absorbed dose distributions in lineal energy for neutrons and gamma rays were measured by using both a tissue-equivalent walled counter (TEPC) and a graphite-walled low pressure proportional counter (GPC) in the Am-Be ...
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 ...
