Abstract: The global activity fields of a nuclear core can be reconstructed using dataassimilation. Data assimilation allows to combine measurements frominstruments, and information from a model, to evaluate the best possibleactivity within the core. We present and apply a specific procedure whichevaluates this influence by adding or removing instruments in a givenmeasurement network possibly empty. The study of various networkconfigurations of instruments in the nuclear core establishes that influence ofthe instruments depends both on the independant instrumentation location and onthe chosen network.
