Abstract
Efficient and reliable conversion of fusion energy into electricity is a crucial requirement for the development of sustainable fusion power plants, overcoming the challenges of high outlet temperatures. Fusion reactors generate high thermal energy at temperature ranges across the divertor 200 °C to 300 °C, blanket 300 °C to 1000 °C, and structural components 150 °C to 250 °C, each with distinct heat fluxes. This review highlights advancements in energy conversion systems, including Rankine, Brayton, combined cycle and hybrid cycles integrated with a primary heat transfer system. The choice of thermodynamic cycle, configuration, and working fluid strongly influences system performance, efficiency, exergy losses, and operational flexibility. Integration strategies for primary heat transfer systems and energy conversion systems are discussed, with a focus on managing high temperature plasma facing components and optimizing power conversion cycles. Insights from operational and conceptual designs demonstrate pathways to enhance efficiency, minimize exergy destruction, and enable resilient, scalable fusion power generation. The review also identifies future directions, including hybrid cycle optimization, advanced working fluids, and adaptive control strategies, to fully harness the thermal potential of fusion reactors and advance sustainable energy solutions.
