As a pivotal player in China’s nuclear energy R&D, the Institute of Nuclear and New Energy Technology (INET) of Tsinghua University has launched the Tsinghua High Flux Reactor (THFR), a next-generation scientific mega-project set to upgrade nuclear fuel testing, isotope production, and neutron research, etc.. The reactor is slated for completion in 2029 at the Rongcheng Research Base of Tsinghua University.

THFR: A Technical Leap

Designed for 80 MW power, THFR combines a compact vessel-in-pool structure with light water cooling and beryllium reflectors. Its innovative reactor core achieves thermal/fast neutron fluxes of 2×10¹⁵ n/cm²/s while enhancing safety through lower power density. The reactor will support fuel and material testing, high specific isotope synthesis, and neutron science. The auxiliary systems encompass hot cells, advanced isotope production lines, etc..

Strategic Impact

Upon commencing operations, THFR will be open for collaboration, serving as a hub for nuclear innovation, interdisciplinary research, and talent development. By enabling domestic production of strategic isotopes and materials, it aims to obviate China’s dependence on imports, empower deep-space missions, and meet China’s medical isotope demands. The project is expected to catalyze advancements in clean energy, aerospace, and healthcare, thereby reinforcing China’s autonomy in the scientific domain.

Currently in the preliminary design phase, THFR further amplifies Tsinghua University’s role in propelling China’s tech self-reliance and fostering next-gen industries.
