The acoustic emission technique is a non‐destructive testing method used for inspection and surveillance of structures and pressurized components. In particular, the purpose of the measurement on the 5 MW research reactor SAPHIR was to investigate and evaluate the abnormally high noise levels during operation of the heat exchangers of the cooling system. The results showed that 5 heat exchangers out of the total of 9 (assembled in 3 groups) were responsible for the higher noise level. This is probably due to some abnormal vibration of the tube bundles therein, caused by the through‐flow of the pool water. Indeed, attempts of localizing the source showed that there must be several, distributed sources.
