Effective use of fusion energy goes hand in hand with effective energy recovery of the generated heat. One of the most promising working medium suitable for this purpose is supercritical carbon dioxide (S-CO2) due to its thermal properties. Six S-CO2 cycle layouts were optimized for the effective use of the heat generated in the DEMO fusion reactor. The main investigated parameter is the outlet temperature from the blanket and the first wall. The temperature range is 350–550 °C. The second parameter is the compressor intake temperature at two temperature levels 25 and 31 °C. The analysis of thermodynamic cycles was performed using new custom-built high-performance computing software. The parametric study of each layout shows the suitability of the given cycle for heat recovery and its sensitivity to the main heat source temperature.
