摘要：

Modular high temperature gas-cooled reactors (HTGRs) have inherent safety characteristics with high reactor outlet temperatures which can be coupled with closed Brayton or Rankine cycles to provide efficient power generation. The helium turbo-compressors and circulators are essential power components that couple the HTGRs with these two cycles. This research investigated the steady-state and dynamic thermodynamic characteristics for a closed helium Brayton cycle for two helium turbo-compressor designs, the 2.2 MW prototype and a 120 MW commercial helium turbo-compressor. Helium circulators were also developed for the 10 MW HTGR (HTR-10) and the HTGR demonstration plant (HTR-PM) with complete performance data for the helium circulators. An experimental platform was then built to test the two types of helium circulators, one with magnetic bearings and one with dry gas seals. This research shows that the Institute of Nuclear and New Energy Technology, Tsinghua University, has developed helium turbo-compressors and circulators for advanced nuclear power plants. © 2021, Tsinghua University Press.
