The transition to low-carbon technologies lies in the support of modern energy sources, which are also represented by fusion power plants. One first plants will be European Union DEMOnstration plant. Among key attributes that influence entire design this plant, belongs conversion system. In addition classic Rankine steam cycle, it is possible use different cooling media, such as supercritical CO2 Brayton cycle. advantages mainly compactness system, is, lower investment costs for plant while maintaining high efficiency question can choice system levelized cost electricity. direct cycles compared cycles, general. On other hand, offer slightly (by approximately 1.5 percentage points), negatively influences electricity 10 %–20 % against cycles.
