In this study, the two-type temperature model of Inertial Confinement Fusion (ICF) reactor as a heat source is used for driving the power generation system. At this fusion reactor model, 1300K-1700K temperature is extracted from the blanket and high temperature about 2000K-2400K can be extracted from the first wall separately. It is known that the gas turbine can use temperature only until 1700K because of its material temperature limitation while an Magnetohydrodynamic (MHD) generator can use high temperature more than 2000K for high efficiency. For that reason, the temperature extracted from the blanket is used for driving the gas turbine cycle and the temperature extracted from the first wall is used for driving an MHD cycle. It is found that, when the MHD enthalpy extraction is 26.5 percent and the first wall output temperature is 2400K, the plant efficiency reaches the highest 55.68 percent. However the fusion output power greatly affects the plant efficiency, therefore sometimes even when the first wall output temperature or an enthalpy extraction increases, the plant efficiency decreases. It is also understood that, because of the gas turbine temperature limitation, the output temperature more than 2400K can not be used.
