Abstract Development of appropriate load following control schemes is an ongoing research interest in the nuclear power plants. As such, a simple state feedback control approach has been proposed in this work for a small modular reactor. A one-fuel/two-coolant model has been adopted to reasonably reflect the coupled thermo-neutronic phenomena inside the reactor core. A feasible state feedback control which makes use of directly measurable coolant node temperatures is employed. Dominant pole placement technique already available for PID controllers is further refined to cover the attempted three term state feedback regulator in this work. To this end, certain theoretical backgrounds have been addressed. Simulation results for the nonlinear model confirm efficient output tracking for the finely tuned closed loop during load following scenarios.
