• A series of experiments on LMFBR local core accidents were carried out in an out-of-pile sodium test loop. In the experiments were used 37- and 61-pin bundle test sections which simulated fuel subassemblies. Throughout these experiments temperature and flow fluctua-tion signals were measured by thermocouples and by an eddy-current type flowmeter that serve to develop an anomaly detection method with high sensitivity.<BR>The experimental results indicate that flow fluctuation at the outlet could be more effectively used for the detection of a large local boiling than temperature fluctuation and that a burst type single cladding failure could be detected by use of the flow fluctuation.<BR>We proposed a real time anomaly detection algorithm based on the whiteness test for the residual random process. A study was made on the relation between the algorithm and the spectral error measure and its performance. It shows the applicability of the method to a real time system and the effective features of the algorithm.
