Abstract EN
BWRs are thus far the simplest energy systems to transform fission energy into electrical power.
However, there are still many aspects in their operation that, under certain conditions, may induce BWR unstable behavior.
The default indicator to study BWR unstable behavior is the Decay Ratio (DR).
However, due to the fact that BWRs show very complex responses under instability and responses that may even be chaotic, the DR might not be a suitable choice to rely on to accommodate for such intricate behavior.
In this work a novel methodology based on the Sample entropy (SampEn) and the noise-assisted multivariate empirical mode decomposition (NA-MEMD) is introduced.
Such methodology was developed thinking for a real time-implementation of a stability monitor.
The proposed methodology was tested with a set of signals that stem from several nuclear power plants in operation today that have experienced in the past unstable events, each one of a different nature.
