[Introduction] The power output of China Fusion Engineering Test Reactor (CFETR) is periodic, which can not directly meet the stable and continuous input requirements of conventional power generation equipment. CFETR fusion power plant needs to integrate a specific process system between nuclear island and conventional island. [Method] By investigating the application of concentrating solar power plants and the literature research of fusion power plants, this paper presented a discussion based on the preliminary performance of CFETR about the comparison between energy storage and energy supplement, energy storage techniques, thermal storage mediums and thermal storage system schemes. [Result] For fusion reactors with water-cooled blanket and helium cooled blanket, it is proposed to integrate an indirect double-tanks sensible thermal storage system with hydrogenated triphenyl heat transfer oil and solar salt molten salt as thermal storage medium respectively, so as to ensure the stable and continuous operation of the power generation system. [Conclusion] The proposed energy storage scheme meets the conditions of large-scale commercial applications and supports the overall design of CFETR fusion power plant.
