The hot helium temperature follows HTR-10's nuclear power changes slowly, and there is a large coupling between them, so the RPHHT system adopts cascade control, the minor loop is fast, and the major loop is hot helium temperature control loop whose dynamic response is slow; there is also a large coupling between main helium loop and steam-water loop, and both the main steam temperature measure signal and the heating process of the once-through steam generator are delayed, therefore, the MHFMST applies cascade control, the minor is main helium flow control loop whose dynamic response is fast, and the major is the main steam temperature control loop whose dynamic response is slow.
