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 ...
Steam-reheat option for supercritical-water-cooled reactors
(2010-12-01)
SuperCritical-Water-cooled Reactors (SCWRs) are being developed as one of the Generation-IV nuclear-reactor concepts. Main objectives of the development are to increase thermal efficiency of a Nuclear Power Plant (NPP) and ...
Electrohydrodynamic enhancement of extraterrestrial capilliary pumped loops for nuclear applications
(2010-12-01)
This work examines electrohydrodynamic enhancement of capillary pump loops (CPL) for use in extraterrestrial nuclear applications. A capillary pump uses capillary action through a porous wick to transport heat and mass. ...
Conceptual design for a re-entrant type fuel channel for supercritical water-cooled nuclear reactors
(2011-04-01)
Current CANDU-type nuclear reactors use a once-through fuel-channel with an annulus gas insulating it from the moderator. The current reference design for a CANDU-type SuperCritical Water-Cooled Reactor (SCWR) is to eliminate ...
