The heat source required to produce the gas flow supplied by the nuclear fission reactor. Using mass, energy and exergy balance equations all cycle equipment have been analyzed individually and energy efficiency, exergy efficiency and irreversibility has been calculated for each of them as required. The results of the analysis show that the maximum efficiency of the first and second law of the cycle at a nominal load of 250 MW with a temperature output of 2300 K and enthalpy extraction 34.79% using a Faraday MHD generator are 51.17%. Paying more attention to the exergy destruction ratio is about 48.83% of the exergy entering in CCMHD cycles. Hence, the remaining 51.17% is converted to power. The MHD generator in this case is the most important cause of exergy destruction in cycle about 20%. Effects of compressor stage number, regenerator efficiency and cooler operating temperature on plant efficiency were studied. ER -
