Table 1 . Pairing of controlled variables and manipulated variables for coordinated control
From: Testing the feasibility of multi-modular design in an HTR-PM nuclear plant
Controller | Controlled Variable | Manipulated Variable | |
|---|---|---|---|
1 | Neutron flux controller | Neutron flux of reactor core | Control rod speed |
2 | Hot helium controller | Hot helium at the primary inlet of steam generator | Revision to the setpoint of neutron flux |
3 | Helium flowrate controller | Primary helium flowrate | Rotational rate of the primary helium blower |
4 | Steam temperature controller | Steam temperature at the secondary outlet of steam generator | Revision to the setpoint of primary helium flowrate |
5 | Feedwater flowrate controller | Feedwater flowrate of the steam generator | Rotational rate of the feedwater pump |
6 | Thermal power controller | Output thermal power of the reactor module | Revision to the setpoint of feedwater flowrate |
7 | Main steam pressure controller | Steam pressure at the inlet of steam turbine | Openings of main steam regulating valve and bypass regulating valve |
