In the design process of nuclear reactor there are three analysis to be done i.e. <br /> <br /> <br /> <br /> <br /> analysis of neutronic, thermal hydraulic analysis and thermodynamic analysis. <br /> <br /> <br /> <br /> <br /> The focus in this &#133;nal project is the thermal hydraulic analysis, which has a <br /> <br /> <br /> <br /> <br /> very important role in terms of system e¢ ciency and the selection of the opti- <br /> <br /> <br /> <br /> <br /> mal design. This analysis is performed in a type of Gas Cooled Fast Reactor <br /> <br /> <br /> <br /> <br /> (GCFR) using cooling Helium (He). The heat from nuclear &#133;ssion reactions in <br /> <br /> <br /> <br /> <br /> nuclear reactors will be distributed through the process of conduction in fuel <br /> <br /> <br /> <br /> <br /> elements. Furthermore, the heat is delivered through a process of heat convec- <br /> <br /> <br /> <br /> <br /> tion in the &#135;uid &#135;ow in cooling channel. Temperature changes that occur in <br /> <br /> <br /> <br /> <br /> the cooling channels cause a decrease in pressure at the top reactor core. The <br /> <br /> <br /> <br /> <br /> governing equations in each channel consist of mass balance, momentum bal- <br /> <br /> <br /> <br /> <br /> ance, energy balance, mass conservation and ideal gas equation. The problem <br /> <br /> <br /> <br /> <br /> is reduced to &#133;nding &#135;ow rates in each channel such that the pressure drops <br /> <br /> <br /> <br /> <br /> at the top of the reactor core are all equal. The problem is solved numerically <br /> <br /> <br /> <br /> <br /> with the genetic algorithm method. Flow rates and temperature distribution <br /> <br /> <br /> <br /> <br /> in each channel are obtained here.
