A Multi-Objective Nuclear Core Control Performing Hot and Cold Leg Temperature Control
Résumé
This paper proposes an innovative evolution of the current Pressurized Water Reactor (PWR) Nuclear Core Control strategies in order to satisfy more and more stringent maneuverability requirements. The following new control objectives are introduced: the hot and cold leg temperatures in contrast to the Average Coolant Temperature (ACT) in standard PWR control designs. This is made possible thanks to the use of the Primary Coolant Flowrate as a new control input. The proposed control design strategy first considers a point kinetic nuclear core non-linear model, calibrated on a highly realistic nuclear core simulation code. Secondly, it proceeds to a multi-objective H 2 /H ∞ control synthesis, using an adequate control structure and non-smooth optimization.
