Three dimensional heterogeneous finite element method for static multi-group neutron diffusion
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
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
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
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. ...
Thermodynamic performance assessment of three biomass-based hydrogen production systems
Hydrogen is likely to be an important energy carrier in the future. It can be produced by the steam reforming of natural gas, coal gasification and water electrolysis among other processes. However current processes are ...
Steam-reheat option for supercritical-water-cooled reactors
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 ...
A generic methodology for the three dimensional display of radiation fields
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 ...

Conversion of a scroll compressor to an expander for organic Rankine Cycle: modeling and analysis
Profile extrusion of wood plastic cellular composites and formulation evaluation using compression molding
Wood Plastic Composites (WPCs) have experienced a healthy growth during the last decade. However, improvement in properties is necessary to increase their utility for structural applications. The toughness of WPCs can be ...
Enhancing geothermal heat pump systems with parametric performance analyses
Parametric performance analyses and comparison of a basic geothermal heat pump, a heat pump cycle with motor cooling/refrigerant preheating, and a heat pump cycle utilizing an economizer with respect to first law is conducted ...
