Development and characterization of a high resolution portable gamma spectrometer
(2012-04-01)
The recent disaster of Fukushima in Japan combined with the high demand to enhance nuclear safety and to minimize personal exposure to radioactive materials has a significant impact on research and development of radiation ...
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 ...
Specifics of forced-convection heat transfer to supercritical water flowing upward in annular and bundle flow geometries
(2016-08-01)
Since annulus- and bundle-flow geometries impede coolant flow, heat transfer to the coolant would occur differently than in bare tubes. The main objective of this work is to propose and verity a universal method to accurately ...
Development of thermodynamic cycles for sodium-cooled-fast reactors.
(2013-12-01)
Currently, one engineering challenge is designing Generation IV (GEN-IV) Nuclear Power Plants (NPPs) with significantly higher thermal efficiencies compared to current NPPs, and to match, or at least to be close to, 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 ...
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 ...
Evaluation of the bubble spectrometer performance in space-like neutron fields
(2021-02-01)
The Space Bubble Detector Spectrometer (SBDS) consists of six bubble detectors each with a different neutron energy threshold. To characterize the spectrometer in a space-like neutron field, a series of experiments were ...
