Hydrogen isotope separation technology is a widely used technology in nuclear fusion reactors, and there are many separation methods, among which thermal cycling adsorption process (TCAP) has the advantages of high degree of automation, strong separation capacity and low tritium retention capacity. In this paper, the development of TCAP technology is reviewed, and the properties and preparation processes of different filling materials (Pd/k, Pd/Al2O3, Pd-Pt) and the research progress of TCAP at home and abroad are highlighted. By comparing the research results at home and abroad, this paper explores the potential of TCAP technology in improving the efficiency of hydrogen isotope separation and reducing costs. Finally, the future research directions are prospected, including the development of new materials, the improvement of the performance of Pd materials, and the optimization of the efficiency of TCAP separation system.
