Özet

The neutronic performance parameters, fissile breeding and temperature distribution in the fuel rod are investigated for different coolants ('He, CO2 'Li2BeF4', 'Li', and 'Li17Pb83') in the fissile fuel breeding zone with volume ratios Of V-coolant/V-fuel, epsilon, (0.5,1,2) under various first wall loads (P-w = 2-10 MWm(-2)) in a fusion-fission reactor fueled with ThO2. Depending on the type of coolant in the fission zone, first wall loads and volume ratios, fusion power plant operation periods between 1 and 4 years are evaluated to achieve a fissile fuel enrichment quality between 1.2274% and 13.7305% in the above mentioned situation for intervals of half month and by plant factor of 75%. A fusion reactor with (D,T) reaction acts as an external high energetic neutron source. The fissile fuel zone, containing 10 fuel rod rows in the radial direction, covers the cylindrical fusion plasma chamber with 300 cm chamber dimension.
