The numerical simulation model has been built and the thermodynamic performance of the system has been further evaluated. As results showed, the thermodynamic efficiency of HHTCC system is up to 50% even based on the helium gas turbine inlet temperature (850°C), which is very promising in the energy conversion system of high-temperature nuclear reactor. Otherwise, the specific power of HHTCC is more than twice over that of conventional combinedcycle and the optimized pressure ratio of this system is also remarkably reduced compared with that of the later.展开更多
