Abstract :
Matched filters are designed for an automatic identification of failed rods in fuel assemblies, which are tested using an ultrasonic pulse-echo method. The detection technique is based on processing echoes from the continuous emitted ultrasonic pulses. All of the failed rods are correctly identified, with a false alarm probability smaller than 3%. Comparisons with other methods are also performed
