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; ...
Neutron production in a spherical phantom aboard the international space station
(2010-12-01)
Since the beginning of space exploration in last century, several kinds of devices from passive and active dosimeters to radiation environment monitors have been used to measure radiation levels onboard different space ...
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 ...
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. ...
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 ...
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 ...
Thermal aspects of using alternative nuclear fuels in supercritical water-cooled reactors
(2010-11-01)
A SuperCritical Water-cooled Nuclear Reactor (SCWR) is a Generation IV concept currently being developed worldwide. Unique to this reactor type is the use of light-water coolant above its critical point. The current research ...
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. ...
Optimization of plastic scintillator thicknesses for online beta detection in mixed fields
(2010-12-01)
For efficient beta detection in a mixed beta gamma field, Monte Carlo simulation models have been built to optimize the thickness of a plastic scintillator, used in whole body monitor. The simulation has been performed ...
