<![CDATA[In this experiment, the study focusses on reactor core thermohydraulic aspects especially the distributions of fuel surface temperature, fluid temperature and fluid axial velocity. Simulation data were obtained in the middle, at the edge and at the comer sub-channels. In this experiment, modeling of hexagonal conï¬guration of reactor core and reflector was carried out. The power generations were assumed constant at 250 kwatt, 375 kwatt and 5 00'kwatt for each ï¬lel element. This model was prepared and analyzed using Fluent Version 4.25 package program available at the Thermodynamic Laboratory of IURC-ES. The result shows that this reactor core model gives low fuel surface and fluid temperatures.]]>
