High-amplitude power oscillations are undesirable in a nuclear boiling water reactor, since they are a disturbance to reactor operation. The core stability is estimated from passive measurements of the neutron flux, using AR or ARMA models, to verify the stability within the operating domain. Our main concern is to estimate the core stability as accurately as possible. The aim of this paper is to...
The aim of this work is to investigate whether it is possible to extract information from process noise measurements by combining physical knowledge with system identification methods. This could be used for implicit measurements of process variables, tuning the model in a multidimensional parameter space, or simply for increasing our knowledge of the dynamical process, for example BWR stability.
