dc.description.abstract-translatedThis doctoral research at Sapienza University of Rome, in collaboration with ENEA and ENI MAgnetic Fusion Energy (MAFE), examines the design and performance of Balance of Plant (BoP) systems for advanced fusion reactors, particularly the ARC and EU-DEMO designs. The study supports global eSorts to achieve commercially viable fusion energy. For the ARC reactor, a compact tokamak developed by MIT and Commonwealth Fusion Systems (CFS) with ENI, the research evaluates three diSerent energy conversion cycles, supercritical Rankine, CO₂ Brayton, and He Brayton, using the software GateCycle and identifying the Rankine cycle as most eSicient and technologically mature. It also explores a preliminary design of a Double-Wall Heat eXchanger (DWHX), analysing transient performance trade-oSs between temperature stability and turbine power output by using RELAP5-3D software. In the case of the EU-DEMO reactor promoted by EUROfusion, the research focuses on the Water-Cooled Lead-Lithium (WCLL) Breeding Blanket, developing a Helical Coil Steam Generator (HCSG) and proposing strategies to manage operational fluctuations. Thermal-hydraulic modeling under steady-state, operational, and accidental scenarios confirms overall system reliability, though some localized hot-spots are noted. Ultimately, the thesis contributes significant insights into the eSiciency, safety, and integration of fusion reactor BoP systems.en
