Abstract :
The inherent dynamic behavior of thermal reactors is governed by external reactivity input and xenon poisoning, as well as other power induced reactivity effects. In that respect, accurate knowledge of xenon concentration and external reactivity is important in reactor control. Sliding mode observers are developed based on Chernick´s model (1960) and point reactor kinetics model to estimate the xenon concentration and reactivity in a nuclear reactor. The simulation results are also shown
