Simulation for the Secondary Loop of the Chinese 200Mwe HTR-PM Base on Vpower

HTR-PM simulator is urgently developed as one of the important major sub-projects of the HTR-PM which is one of the Major national science and technology projects. The HTR full-scope simulator is currently still a blank throughout the world. In this situation, based on the vPower simulation platform, the structure of the simulation system of secondary loop was presented in detail in this paper, and the whole system was jointly debugged between secondary loop and the steam generator of Nuclear island side by embedding THERMIX /BLAST code into the vPower simulation environment. Steady state and transient process of some key parameters have been studied by the help of this simulation system. Current simulation results analysis shows that it is agreed with the design values and expectations and fitted for practical application
