It is known that fusion reactions are fueled by deuterium and tritium, which are found easily in water and are known as unlimited energy resource, would release enormous energy for driving power generation system. The aim of this study is to examine and compare the plant efficiency of power generation systems using magnethydrodynamic (MHD) generator, Gas Turbine (GT), Steam Turbine (ST) and Inertial Confinement Fusion (ICF) reactor as heat source to generate electrical power. Three systems were considered including the MHD single system, the MHD/GT system and the MHD/ST system, and the highest plant efficiency of each system was 61.06%, 58.34% and 60.76% respectively. This result showed that the MHD single system could be expected as the most effective system because of the highest plant efficiency and the simplest system. However, it also showed that the plant efficiency decreased with the increase of the reactor outlet temperature because of the reactor's blanket limit temperature. For this reason, it was understood that too high a reactor outlet temperature was not desirable. The temperature of 1999K and enthalpy extraction of 33.5% would be most preferable parameters to MHD single system.
