In this work we have presented an estimation algorithm based on Kalman filter to monitor the condition of the core of AGR nuclear stations. In particular, using data stored during the core refueling phase, it is possible to estimate the friction force that the fuel rod apply on the supporting brushes which are embedded in the core wall. In this way it is possible to estimate the shape of the graphite bricks that compose the core and therefore the condition of the core itself.
