Abstract: We apply a data assimilation techniques, inspired from meteorologicalapplications, to perform an optimal reconstruction of the neutronic activityfield in a nuclear core. Both measurements, and information coming from anumerical model, are used. We first study the robustness of the method when theamount of measured information decreases. We then study the influence of thenature of the instruments and their spatial repartition on the efficiency ofthe field reconstruction.
