Abstract: The synthesis of superheavy elements has long been one of the forefront topics in the field of nuclear physics. Utilizing actinide rare nuclides as target materials and inducing nuclear reactions with heavy-ion beams represent a key approach for synthesizing superheavy elements. However, the stable supply of actinide rare nuclide targets has become a critical bottleneck restricting further advancements in superheavy element synthesis. The Tsinghua High Flux Reactor (THFR), characterized by its high neutron flux and strong irradiation capability, can provide essential support for the production of actinide rare nuclide targets, thereby facilitating the experimental discovery of superheavy elements. This paper first reviews recent progress in superheavy element synthesis and then explores potential pathways for applying THFR to cutting-edge nuclear physics research, with a focus on analyzing the feasibility of using THFR to supply target materials for superheavy nuclei synthesis. Through theoretical calculations, key parameters such as yield and purity of the primary actinide rare nuclide targets that can be produced by THFR are presented. The findings offer valuable references for preparation of targets on superheavy nuclei synthesis based on ultra-high flux reactor.
